any losses or damage to the product incurred while the product is in transit or is being shipped
for repair. Insurance is recommended.
LIMITATION OF IMPLIED WARRANTIES - Except as set forth above, all other expressed or implied
warranties, including those of fitness for any particular purpose and merchantability, are hereby
disclaimed. Some states do not allow limitations on warranties, so the above limitation may
not apply to you.
EXCLUSIONS - This warranty does not cover the following: Installation, Finishes, Defects resulting
from installation. Any damage due to accident, resulting from inaccurate satellite transmissions.
Inaccurate transmissions can occur due to changes in the position, health, or geometry of a
satellite. Any damage due to shipping, misuse, negligence, tampering or improper use. Servicing
performed or attempted by anyone other than an authorized AvMap representative.
Attenzione! L’esposizione del display ai raggi ultravioletti può accorciare la vita dei
cristalli liquidi usati nel vostro plotter cartografico. Questo limite è dovuto alla tecnologia costruttiva
degli attuali display. Evitare inoltre che il display si surriscaldi per non causare una diminuzione di
contrasto che, in casi estremi, può rendere lo schermo completamente nero. Tale condizione è
comunque reversibile durante il raffreddamento.
Warning! Exposure of display to UV rays may shorten life of the liquid crystals used in
your plotter. This limitation is due to the current technology of the LCD displays. Avoid overheating
which may cause loss of contrast and, in extreme cases, a darkening of the screen. Problems which
occur from overheating are reversible when temperature decreases.
Achtung! Ultraviolette Strahlen können die Lebensdauer vom Flüssigkristalldisplay
verkürzen. Die derzeitige LCD-Technologie bedingt diese verkürzte Lebensdauer.
Überhitzung des Displays durch Sonneneinstrahlung führt zu einem Kontrastverlust und in extremen
Fällen sogar in eine Schwär zung des Bildschirmes. Bei sinkenden Temperaturen normalisiert sich
der Kontrast wieder und die Bildschirminformation wird wieder ablesbar.
Attention! L’exposition de votre écran LCD aux ultra-violets lors de soleil intense
réduira la durée de vie de l’afficheur de votre lecteur. Cette contrainte est liée à la technologie des
écrans LCD. Une augmentation trop importante de température peut obscurer des zones de votre
écran et le rendre ainsi inutilisable (non couvert par la garantie).
Aviso! La exposición de la pantalla a los rayos UV puede acortar la vida del cristal líquido
usado en su ploter. Esta limitación se debe a la tecnología actual de las pantallas LCD. Evitar que
la pantalla se caliente en exceso pues puede causar pérdida de contraste y, en caso extremo, la
pantalla puede quedar totalmente negra. Este problema revierte al enfriarse la pantalla
Warning!!!
A measure of knowledge by the user is required for proper and safe use of the chart plotter.
Read the User Manual and the Warranty completely.
Use Good Judgement
This product is an excellent navigation aid, but it does not replace the need for careful
pilotage and good judgement. Never rely solely on one means of naviga-tion.
Use Care to Avoid Inaccuracies
The Global Positioning System (GPS) is operated by the U.S. Government, which is solely
responsible for the accuracy and the maintenance of GPS. Certain conditions can make the
system less accurate.
Accuracy can also be affected by poor satellite geometry.
The accuracy of position fixes is subject to changes in accordance with the Department of
Defense civil GPS user policy and the Federal Radionavigation Plan.
Cleaning Procedure for the Chartplotter Screen
Cleaning of the chartplotter screen is a very important operation and must be done carefully.
Since the surface is covered by a antireflective coating, the procedure for cleaning all the
surfaces can be performed using the following procedure: You need a tissue or lens tissue
and a cleaning spray containing Isopropanol (a normal spray cleaner sold for the PC screen,
for example PolaClear by Polaroid). Fold the tissue or lens tissue into a triangular shape,
moisten the tip and use the index finger behind a corner to move the tissue across the
surface, in overlapping side to side strokes. If the tissue is too wet, a noticeable wet film will
be left in its path and you will need to repeat the process. If too dry, the tissue won’t glide
easily, and may damage the surface.

1.3 FLYING START
These pages provide a very brief overview of several of the EKP-IV’s important features, the Main
Menu, the Moving Map, GoTo flights and locating a Waypoint in the Database. It does not replace
the User Manual, which should be read to get the fullest possible use from your EKP-IV.
Note
The EKP-IV is an aid to navigation. It does not replace paper charts and good judgement.
13
1.3.1The Moving Map
Before starting, connect the EKP-IV to power and place the antenna with a clear view of the sky.
Turn On the unit pressing ‘POWER’. Press ‘ENTER’ to exit from the Warning page and enter the
Moving Map mode. The Moving Map is the default state displaying the Moving Map screen and the
Data Window. The Data Window contains navigation information boxes (See Chapter 3 for details
on Moving Map mode).
Note: If no Fix is available, red dashed cross is displayed over the map for increased Pilot
Awareness.
To Change the Scale of the Moving Map
Use ‘ZOOM IN’ and ‘ZOOM OUT’ to change the map display scale.
To Select Position
Use the cursor key to scroll to the location you want.
1.3.2The Main Menu
From Moving Map press ‘MENU’ for 1 second to display the Main Menu:
Fig. 1.3.2 - Main Menu
1.3.3 Moving Map Functions
The Moving Map operates in Auto Home, Auto Zoom, and Cursor Mode. The screen will behave
differently based on the mode of operation selected. The Auto Home mode will allow the user to
pan away from his present position to view other parts of the map, and return to present position
automatically when no buttons are pushed for a pre-determined amount of seconds. Auto Zoom
mode will keep your present position, and your destination in the screen at all times. The screen
will automatically zoom in as you get closer. To shut off this function, simply select OFF.
The Cursor Mode (OFF Selected) will allow you to move the map to any position to view data or
details. To return to your present position, just press ‘CLEAR’ while in moving map.
The control for these functions is found in the Moving Map Menu, under Auto Position Mode.
14
1.3.4 Moving Map Icons
The following icons are displayed on the Moving Map to represent Waypoints, navigation aids and
airports.
Fig. 1.3.4 - Moving Map Icons
1.3.5 Course Predictor
Indicates the projected position at the set time interval if the current speed and heading are kept.
This allows the pilot to correct for wind drift, in real time, right from the moving map. To select
course predictor:
> ‘MENU’ 1 sec. + “SYSTEM SETUP” + ‘ENTER’ + “FIX SETUP” + ‘ENTER’ + “COURSE
PREDICTOR” + ‘ENTER’
1.3.6 GoTo
GoTo sets a 1-leg course from the present position to any location or selected Waypoint. To activate
a GoTo Flight Plan move the cursor to the desired location or Waypoint and press ‘GOTO’. The
GoTo menu box will open enabling you to activate the current cursor position or search the
Database for a specific object to fly to. To activate the current cursor position, highlight “CURSOR”
and press ‘ENTER’. To activate a GoTo Flight Plan to a specific Database item, select the category
and press ‘ENTER’. Select the database item and press ‘GOTO’ again to activate.
15
To deactivate, press ‘GOTO’ and select “DEACTIVATE”.
1.3.7 Crossed Airspaces Advisor
> GOTO + “CROSSED AIRSPACES ADVISOR”
When this function is enabled, every time a new leg of an active FP is entered, the navigator
warns with an alert whether the leg is approaching an airspace among the ones selected in the
function sub menu. The message contains the list of the approaching arispaces. As soon as a new
leg is entered, or a new destination is set with the Direct To function, an altitude check is made in
order to detect all the crossed airspaces in a 3D space at the current FIX altitude. The fix altitude is
registered, but when changes of more than 500 (five hundred) feet occur, the advisor triggers again
the check and saves the new altitude.
1.3.8Database
The Database function allows the user to access information stored in the data cartridges on
Airports, VOR’s, NDB’s, Intersections and User Waypoints. Searching the Database allows the user
to activate GoTo Flight Plans and locate the item on the map. There are two methods of accessing
the Database information. The first is through the Database function within the Main Menu and the
second is directly from the Moving Map display (see Chapter 3).
1.3.9 Battery Compartment and Batteries
The EKP-IV is designed with a battery compartment for 6 rechargeable AA batteries. It is located
in the rear of the unit underneath the removable knee mount. The unit provides a ‘trickle’ charge
to the batteries when the unit is plugged into external power and powered ON. Rechargeable AA
batteries are required. Install them only after the batteries are fully charged. With fully-charged
batteries, the normal discharge time will be close to two hours, depending upon the condition of
the batteries, as well as the brightness and contrast of the screen settings. AvMap highly recommends
that NiMH AA batteries be used (available from AvMap/Navigation, or from any electronics shop).
DO NOT USE ALKALINE BATTERIES, as they may damage the unit and void the warranty.
16
2The Basics
This chapter provides general information about the functions of the keys and entering data
(connecting the EKP-IV to power and using the antenna are described in Chapter 15).
2.1THE KEYBOARD
The EKP-IV has 10 keys, which access and control features. Some keys perform different tasks
based on the operation mode. A quick key guide is displayed at the bottom of many menus for
easy reference.
Below we indicate the keys in capital letters enclosed between single inverted commas, for example
‘MENU’. When a key, for example ‘MENU’, must be pressed and held down for more than 1
second it is shown as ‘MENU’ 1 sec.
The POWER key
‘POWER’: press and hold to turn the EKP-IV On.
‘POWER’ 3 seconds: once the EKP-IV has been turned On turns the EKP-IV Off.
‘POWER’: (immediately release!) once the EKP-IV has been turned On displays the Brightness and
the Contrast Menu.
The PAGE key
Displays a list of the 20 nearest objects, including private airports which contain runways of at least
500 ft. in lenght, relative to fix position or cursor position if no fix is available. Press and hold to
access the NavData Page.
The GOTO key
Activates a Flight Plan to the cursor position (in Moving Map) or to selected object (in other
modes).
The ZOOM-OUT key
Shows less detail of a larger area by changing the chart scale and zooming out on the map display.
The CURSOR key
Moves the cursor on the Moving Map, quickly and accurately. Also scrolls to the desired options
in menu page(s).
The ZOOM-IN key
Shows more detail of a smaller area by changing the chart scale and zooming in on the map
display.
The MENU key
‘MENU’: selects the Moving Map Menu.
‘MENU’ 1 sec.: opens Main Menu (equivalent to press ‘MENU’ twice).
The ENTER key
Selects the desired option or confirms selection. Also opens the Cursor/Position Menu.
The CLEAR key
Rejects an action, closes a window or activates Home or Auto Zoom mode. By pressing and holding
CLEAR button for 2 seconds the Fix icon can be positioned on the 20% central area of the map

The operation mode will determine the options available within the screen. The Data Window
contains the navigation information pertaining to the active flight; these fields can be customized.
From the Moving Map screen you can obtain Automatic Info and Full Info for Database objects.
Here you can also open the Cursor/Position Menu for features related to Flight Plans, Waypoints
and airspace.
3.1OPERATING MODES
3.1.1 Cursor Mode
In Cursor mode the screen is controlled by your movement of the cursor. When in Cursor mode, a
data field line will appear under the Data Window providing LAT/LON of the cursor position. If a fix
has been computed, a distance and bearing will also appear from the position fix to the cursor.
When in Cursor mode it is possible to scroll on the map such that the position fix will not be
displayed on the screen. When this occurs, you can quickly display your position by activating
Home mode (press ‘CLEAR’ once). At this time, the system will operate in Home mode (see below
Par. 3.1.2).
If you have a position fix, and would like to continue with the cursor at the last position, press
‘CLEAR’ again (if the cursor key have not been pressed between these two ‘CLEAR’ presses, the
cursor will revert to the original position). To activate the cursor from the current fix position, simply
press the cursor key and the Cursor mode becomes active at the present fix position. The cursor can
be used to create and edit Waypoints and Flight Plans; identify airspace, obtain info about objects,
project radial lines and measure distance (see Cursor Menu, Par. 3.6).

The shaded elevation map — Terrain Depiction — and associated software features are designed
to aid pilots by graphically and numerically displaying the approximate elevation of any location on
the map. It is not designed to replace any onboard altitude/elevation instrumentation (i.e. altimeters
or other altitude/elevation measuring devices).Terrain Depiction can be displayed in either the
Vertical or Horizontal display modes.
The “Map Orientation” is set to Track-Up and the Terrain Depiction is set to ON at system start-up,
and can be changed as needed (see below for instructions on how to change the Map Orientation
from Track-Up to Course-Up or North-Up, as well as how to turn OFF the Terrain Depiction Shaded
Land Elevations).
Note
Course Up mode with Terrains (TAWS) is aligned to Track Up behaviour and Map rotation on TRACK UP mode is
made continuously in accord with the HEAD UP RESPONSE setting when in any TERRAIN mode.
3.5.11.1Terrain “ON”
With the “Terrain” set to ON, the following occurs:
• With Map Orientation set to North-Up and Track-Up, the Terrain Depiction is displayed on all
mapping scales from 1 Nm and above. No Terrain Depiction is displayed with the mapping scale
from1/2 Nm and below.
• With the Map Orientation set to Course-Up, no Terrain
Depiction occurs on any map scale.
Note: Terrain Depiction is disabled at 1/2 mile and below to allow for a normal Track-Up Map
Orientation to be used thus allowing for airport traffic patterns to be displayed on the map.
To turn-on/off the land elevation mapping, follow these steps:
> ‘MENU’ + “TERRAIN” + ‘ENTER’
To change map orientation:
> ‘MENU’ + “MAP ORIENTATION” + ‘ENTER’
With “Terrain” set to OFF, the following occurs: Normal mapping is displayed at all map scales
(without shading).
Determining the Elevation of any area on the map (with “Terrain” turned ON):
The cursor, when moved anywhere on the map, will open up a dialog box that will give the
approximate elevation of that point on the map. Units of measurement default to feet. To switch
to meters, go to MENU.
> ‘MENU’ x3+ “UNITS SETUP” + ‘ENTER’+”ALTITUDE”
3.5.11.2TAWS
TAWS (Terrain Awareness Warning System), depicts the separation that exists between the terrain
and the airplane.
In order to properly display TAWS, you’ll need to configure the EKP-IV. In MAP mode, press the
MENU key, select TERRAIN and press ENTER. A menu is displayed. Select TAWS and confirm by
pressing ENTER.
Important Note: After TAWS is enabled; TAWS will not be displayed on the map. You will need to
acquire a position fix. The simulation mode can be used for training purposes. Press the MENU key
34
twice and select ‘Simulator’ from the Main Menu. Press ENTER, and set to “ON.”
Once TAWS has been enabled, the EKP-IV will display a legend in the lower left corner of the
display that depicts the TAWS color scheme:
Fig. 3.5.11.2- TAWS
Please Note
When TAWS is enabled, the color scheme is always displayed. The rules for TAWS are divided into two levels:
1. L1=500 ft. agl / M1=1,000 ft. agl / H1=2,000 ft. agl
2. L2=1,000 ft. agl / M2=2,000 ft. agl / H2=3,000 ft. agl
The TAWS rules allow you to calculate the color scheme to be used for depicting the OCH: Obstacle Clearance
Height.
The OCH: Obstacle Clearance Height, is the difference of your own altitude (GPS Altitude) less
the Land Elevation:
OCH = ALT – LE
This calculation considers the Lowland and Highland definition, where:
A - Lowland is the terrain under 3,000 feet of elevation
B - Highland is the terrain over 3,000 feet of elevation
In the Lowland case, the TAWS colors will be red, yellow and green according to the following
values of the OCH:
§ Red: L1= from < 0 ft. up to 500 ft.
§ Yellow: M1= from </= 500 ft. up to 1,000 ft.
§ Green: H1= from </= 1,000 up to 2,000 ft.
§ Transparent (no color): > 2,000 ft.
In the Highland case, the TAWS colors will be red, yellow and green according to the following
35
rules of the OCH:
§ Red: L1= from < 0 ft. up to 1,000 ft.
§ Yellow: M1= from </= 1,000 ft. up to 2,000 ft.
§ Green: H1= from </= 2,000 up to 3,000 ft.
§ Transparent (no color): > 3,000 ft.
In the Auto case, the EKP-IV shifts the level of the TAWS depending terrain altitudre.
In addition to the TAWS legend in the lower left corner of the screen, all vertical obstructions (i.e.
towers, tanks, etc.) will be displayed in the appropriate TAWS color scheme.
Note
If no Fix and/or no Altitude are available, TAWS legend window content is displayed with red background and
warning message “NO ALTITUDE NO TAWS AVAILABLE” .
3.5.12Selective Display Settings
In addition to the above Moving Map Settings the Selective Display feature allows you to further
customize the display by selecting the chart scale level at which the category of data will begin

Fig. 4 - Nav/Location screen
4.1NAVIGATION & LOCATION DATA
The Navigation data displayed in this window is based on the current Flight Plan leg or active
Waypoint. If no Flight Plan is active, only Ground Speed and Track can be displayed. The CDI is
a graphic display of Cross Track Error (XTE). The airplane remains at the center, with the course
line needle moving right and left in relation to the airplane icon. When the line is to the left of the
airplane, you are right off course and must turn left (fly to the line) to close on the course.
Note
Distances are measured horizontally.
If the icon rotates 180° and points toward the bottom of the display, you are moving away from the
destination. The numbers on either side of the CDI represent a full-scale deflection.
To change the CDI scale press the left/right cursor key.
The EKP-IV references navigation information to the next Waypoint in the active Flight Plan. When
you reach the destination of one leg, the EKP-IV automatically switches to the next leg.
This leg switching occurs when the airplane crosses the bisector of the 2 legs, as shown in
the diagram. The pilot may choose a different leg (forward of the present location) by using the
Flight Plan menu and activating the leg destination.
38
> ‘MENU’ 1 sec. + “FLIGHT PLAN” + ‘ENTER’

7 The Global Positioning System
The Global Positioning System (GPS) is a constellation of satellites that orbit the earth twice a day,
transmitting precise time and positioning information to anywhere on the globe, 24 hours a day.
The system was designed and deployed by the U.S. Department of Defense to provide continuous,
worldwide positioning and navigation data to U.S. and allied military forces. GPS broad commercial
applications were recognized early in the system’s development, and the U.S. government decided
to allow free access to GPS signals. Today, GPS is used in a wide variety of commercial and scientific
applications.
7.1 GPS PAGE
The GPS page shows GPS data in graphic mode, displaying satellite availability and status.
> ‘MENU’ 1 sec. + “GPS PAGE” + ‘ENTER’
Fig. 7.1 - The GPS page
This page displays the current status and location of all available satellites in the GPS constellation,
referenced to the initial position or last fix.
On the bottom half of the screen (see previous figure) there is a polar representation of the Azimuth
and Elevation of the satellites used to compute a position fix.
The Elevation is the height of the satellite above the horizon, with 5° (lowest) near the horizon and
90° (highest) being directly overhead (the EKP-IV does not normally use satellites with Elevations
lower than 10°). Azimuth is the satellite’s location in relation to true north, measured clockwise as
a bearing. A satellite with an Azimuth of 90° is to the east.
The circle contains a number indicating the number of the satellite and it is green (or blue for WAAS
satellites) when it is used for the fix solution (red otherwise). On the left side there are histograms
indicating the S/N ratio (SNR). The bar is green (or blue for WAAS satellites) when the satellite is
used for the fix (red otherwise). When a valid fix is received, the EKP-IV displays the current position
47
coordinates, Date, Time, HDOP, VDOP,GS, TRK and ALT on the GPS page.

7.3HOW GPS WORKS
Each GPS satellite continuously broadcasts two signals: an SPS (Standard Positioning Service) signal
for worldwide civilian use and a PPS (Precise Positioning Service) signal for U.S. and Allied military
use. The SPS signal is a spread-spectrum signal broadcast at 1575.42 MHz. The signal is virtually
resistant to multipath and nighttime interference and is unaffected by weather and electrical noise.
All commercial and consumer GPS receivers are SPS receivers.
The SPS signal contains two types of orbit data: almanac and ephemeris. Almanac data contains the
health and approximate location of every satellite in the system. A GPS receiver collects almanac
data from any available satellite, then uses it to locate the satellites that should be visible at the
receiver’s location. Ephemeris data represents the precise orbital parameters of a specific satellite.
Receivers listen to signals from many satellites simultaneously and triangulate a position fix using
the interval between the transmission and reception of each satellite signal (a receiver tracks more
satellites than are actually needed for a position fix, so that if one satellite becomes unavailable, the
receiver knows exactly where to find the best possible replacement).
Three satellites are required for two-dimension positioning (which determines position only) and
four satellites are required for three-dimension positioning (to determine position and elevation).
7.3.1 Accuracy
In general, an SPS receiver can provide position information with an error of less than 25 Meters
and velocity information with an error of less than 5 Meters per second. For applications that require
much greater accuracy the effects of SA and environmentally produced errors can be overcome by
using a technique called Differential GPS (DGPS), which increases over-all accuracy.
7.3.2 WAAS
The Federal Aviation Administration (FAA), in cooperation with other DOT organizations and DOD,
is augmenting the GPS/SPS with a satellite-based Wide Area Augmentation System (WAAS). WAAS
will provide a signal-in-space to WAAS compatible receivers to support en route through precision
approach navigation. After achieving initial operational capability, WAAS will be incrementally
improved to expand the area of coverage, increase the availability of precision approaches, increase
signal redundancy and reduce operational restrictions.
7.3.3Differential GPS
Differential GPS (DGPS) uses a GPS receiver at a fixed point with a known position of sub-meter
accuracy. This is the control unit. The receiver collects data for all visible satellites and computes
predicted satellite ranges, which are compared with actual ranges. The difference is the satellite
range error, which is converted to correction signals for use by a roving receiver.
It is assumed that this correction will be the same for other GPS receivers that are in the same
area and are using the same satellites for positioning. If the correction is communicated to other
receivers in the area (usually by a beacon on the same site), the range error can be removed from
satellite signals and precise fixes calculated by these receivers.
It should be noted that not all data errors can be corrected in this way. Errors that are caused
by receiver noise (which is inherent in any GPS receiver) and multipath problems cannot be
eliminated with differential corrections. (Multipath errors occur when the receiver’s antenna “sees”
48
the reflections of signals that have bounced off of surrounding objects.)
Using DGPS to eliminate the effects of correctable errors requires that the user’s GPS receiver be
connected to a compatible differential beacon receiver and be within range of the broadcasting
beacon. The differential beacon receiver accepts and demodulates the broadcast corrections, which
are then relayed to the GPS receiver. The GPS receiver applies the corrections to the navigation
data it uses to compute a position solution and displays differentially corrected data. Care must be
taken to ensure that the DGPS receiver and the GPS receiver are compatible for this procedure to
be successful.
7.3.4 Monitoring & Controlling The GPS
The Global Positioning System is monitored and controlled by the U.S. Air Force, which is responsible
for updating and maintaining exact satellite position and signal data accuracy.
It is also responsible for performing maintenance on the satellites, which may require the satellite
being taken off-line. Since the system is subject to periodic updates and changes, the almanac data
broadcast by the satellites is current for a limited time — generally about 14 days.
7.3.5 GPS Information Sources
The needs of the worldwide civil GPS user community are served by the Civil GPS Information
Center (GPSIC) in Virginia. The GPSIC is operated and maintained by the U.S. Coast Guard for the
Department of Homeland Security.
Its primary function is to provide information on the Global Positioning System and satellite status
and to serve as a point of contact.
The GPSIC has general GPS literature available free upon request. The Center also maintains upto-date almanac data and Operational Advisory Broadcasts containing current constellation status
and planned satellite outages.
There are three ways to quickly obtain current information about the Global Positioning System
from the GPSIC:
1.Recorded phone message at (703) 313-5907
2.WebSite: www.navcen.uscg.mil
3.Live information at phone (703) 313-5900.

8 Waypoint & Database
The EKP-IV uses three types of Waypoints:
Jeppesen Waypoints are contained in the Compact Flash and include Airport, VOR, NDB and
Intersection Waypoints. Each of these Waypoints is displayed on the Moving Map by an icon. These
Waypoints can be searched in the Database Menu and identified on the Moving Map with Quick
Info or Full Info. Each of these Waypoints can be used in a Flight Plan, for the Nearest Search or
GoTo functions. When used in a Flight Plan, details regarding the Waypoint are displayed in the
Destination box during flight (when DEST is chosen for display in the Data Window, see Par. 3.5.2).
Our Jeppesen library is updated every 28 days. The info regarding the Jeppesen cycle (the cycle
number, the validity period Start Date and Expiring Date) displayed on Title page and on About
page. Please contact your local C-MAP office for update orders and pricing.
User-Defined Waypoints (also called User Waypoints) are created by the user. The user can create
unique 8 character names and choose from 16 icons for each waypoint. Waypoints can be created
and edited both on the Moving Map and in the User Waypoint Database page. Like the Jeppesen
Waypoints, they can be used in a Flight Plan, for the Nearest Search or GoTo functions. The EKP-IV
can store up to 1,000 User-Defined Waypoints within the internal memory. The internal waypoint
memory capacity is shared with Flight Plan waypoints; i.e. if you have 15 flight plans with 10
waypoints stored in the unit memory, there is room for 900 User Waypoints.
Temporary Waypoints are created only on the Moving Map and are associated with a particular
Flight Plan. They are named in the format WPT001, WPT002 etc. Temporary Waypoints can be
used at the beginning, middle or end of Flight Plans. They can be used as the destination of a
Direct-To Flight Plan, but cannot be accessed in the Nearest function.

9 Approach Data Procedures
WARNING!!!
The EKP-IV is not certified for use as the only navigation device during Instrument Flight Rules as established by the
FAA. Instrument approach points displayed in the unit are for information only and do not establish authority for
a pilot to fly the IFR approach procedure in actual instrument flying conditions. For IFR flight. The final “Approach
Segment & Missed Approach Point” the EKP-IV is to be used strictly as a monitoring instrument only.
An approach procedure is a series of pre-determined maneuvres for the orderly transfer of an
aircraft, under instrument flight conditions, from the beginning of the initial approach to a point
from which a safe landing may be made visually. Generally, the approach pattern and procedure is
not chosen until arrival in close proximity of the destination airport, since conditions may change on
route. To activate an “Approach” it is necessary to have an active “Flight Plan” or “GOTO”.
For each airport with at least one published final approach, there exists one or more named
approach procedures. Each approach procedure can be related to a runway and to nearby NavAids
(such as ILS, VOR, NDB, GPS...).
9.1 APPROACH FROM THE MOVING MAP
Note
You must start with an empty flight plan.
While navigating or planning in the moving map screen, the pilot will not be able to establish an
approach on a flight plan, without changing into the Flight Plan mode, but can place the cursor over
the selected airport. To display the quick data box press:
> ‘ENTER’ 1 sec + ‘ENTER’ (for detailed information).
The detailed information on the airport will be displayed, beginning with the general information
and frequencies. By pressing the cursor key on the left, the approaches for the chosen airport will
display in the box and the bearing for the viewed approach will display on the moving map. By
continuing to press the cursor key on the left the other approaches for the airport will display, the
last bearing for the last approach viewed will become white on the moving map and the bearing for
the viewed approach will be displayed in black on the moving map.
Note
The white approach bearings will disappear once the screen redraws itself.
9.2 APPROACH FROM FLIGHT PLAN DATABASE
Refer to Chapter 6 for Flight Planning.
Flight Plan mode allows the pilot to plan and activate up to ten flight plans with up to 100 individual
legs each. Now the EKP-IV allows the pilot to pre-program an approach at the destination end of
the flight plan and to change the approach as desired.
Once an airport is present as a final waypoint in the flight plan, press ‘MENU’ and “SELECT
APPROACH” + ‘ENTER’ and the available approaches for the destination airport will be displayed.
Highlight the approach desired, press ‘ENTER’ and the waypoints associated for that approach will
show in the flight plan list. Press ‘CLEAR’ + ‘CLEAR’ and the flight plan will appear on the moving
map.
54
To change the desired approach for the airport, if one is selected
> ‘MENU’ + ‘MENU’ + “FLIGHT PLAN” + ‘ENTER’ + ‘MENU’ + “CHANGE APPROACH”
- select the approach + ‘ENTER’.
This will substitude the previous approach including the waypoints on the moving map for the new
approach and add the new waypoints to your flight plan and the moving map.
To remove desired approach
> ‘MENU’ + ‘MENU’ + “FLIGHT PLAN” + ‘ENTER’ + ‘MENU’ + “REMOVE APPROACH”
+ ‘ENTER’.
9.3 SELECT APPROACH FOR GOTO
If a ‘GOTO’ to an airport is active or an FP containins an airport as destination point, pressing
“GOTO” from the map will display the GOTO menu (regardless of your cursors position).
If an approach to the destination airport is not yet selected (the approach has to be present in the
Jeppesen® database), the “GOTO Menu” will display “Select Approach”.
If an approach is already selected, the “GOTO Menu” will show the options: “Change Approach”
or “Remove Approach”.
Selecting “Select Approach” or “Change Approach” will open a new window with available
approaches for the destination airport.
After selecting the desired approach, the EKP-IV will remove the GOTO destination airport
and replace it with the approach waypoints. The ‘GOTO’ destination is now the first approach
waypoint.
The EKP-IV will take you to the first point of the approach, and after passing through this point
automatically, will go to each of the other points of the approach. Selecting “Remove Approach”
removes the approach waypoints from the GOTO destination replacing them with the corresponding
airport waypoint (that was originally selected).
Activating a GOTO with an Approach from database
If you are in the airports database page
> ‘MENU’ + ‘MENU’ + “DATABASE” + “AIRPORTS”
and the screen is displaying approach information, by pressing ‘GOTO’ you will activate a ‘GOTO’
to the selected airport and automatically opened the “Select Approach” window.
If you don’t want to select any approaches just press ‘CLEAR’.

The Countdown Timer will sound an alarm at the end of the set time interval. The time calculations
continue in the background of the software, even if you are not on the Calculator page or do not
display the timer data in the data fields window.
The system does require a GPS fix to begin the timer, as the calculation of time is based on the GPS
data. If the GPS fix is lost during this mode, the timer will display dashes in the right hand column.
The time calculation will continue to work in the background.
> ‘MENU’ 1 sec. + “CALCULATOR” + ‘ENTER’ + “COUNTDOWN TIMER” + ‘ENTER’
A box will appear in the right hand column allowing you to set the hours, minutes and seconds. Using
the cursor key select the number desired and press ‘ENTER’ to accept and begin the countdown.
Entering 00:00:00 equals Off. The default setting is Off (00:00:00).

press ‘ZOOM IN’ + ‘ENTER’ to confirm action.
To Clear all totals (all fields): While on the Trip Computer Page, press ‘ZOOM OUT’ + ‘ENTER’
to confirm action.
10.4VERTICAL NAVIGATION
The Vertical Navigation (VNAV) function prepares a descent profile and recommends a descent
to the altitude of the destination of the active Flight Plan or to some OFFSET point from the
destination. The Vertical Situation Indicator in the HSI display is activated with this function (the
units of measure used for the values entered here are selected from Units Setup menu in the System
Setup Menu, see Par. 14.5). This feature requires that a Flight Plan be activated.
> ‘MENU’ 1 sec.+ “CALCULATOR” + ‘ENTER’ + “VERTICAL NAVIGATION” +
‘ENTER’
User data is entered in the fields at the bottom half of the screen. To set Vertical Navigation
parameters use ‘ENTER’ to edit the selected field (a box appears around the active field) and the
cursor key to move between fields. Press ‘CLEAR’ to return to Calculator menu.
Note
The Vertical Navigation solution estimates the target altitude (altimeter reading) from glideslope, distance to the
Waypoint, and the total altitude change. GPS altitude is not accurate enough for stand alone vertical navigation.
Some values are automatically displayed. Time To Go, Distance, Descent Rate and Altitude From
are based on current GPS data. An Altitude To is displayed if a Traffic Pattern Altitude for the
destination exists in the Database. Altitude From, Altitude To, Offset Distance and Glide Slope can
be edited. Vertical Navigation is a full screen page with the following structure:
Fig. 10.4 - Vertical Navigation page
58
Fig. 10.4a - Vertical Navigation function
Vertical Navigation can be activated (On) only if a Flight Plan is active (destination present).
Destination point for Vertical Navigation is the last point of the Route or destination of GoTo
mode.
Prior to the Descent Point being reached the Distance To Go displays TO, Time To Go to Descent
point and Descent Rate from the current position. After passing Descent point the system displays
TO, Time To Go to the Destination and Target altitude based on actual descent profile. Time To
Descent or Target ALT values can be displayed in the Data Window of Moving Map and HSI modes.
The Vertical Navigation value displayed in the HSI is calculated as a difference between current
altitude (from GPS) and Target altitude.
10.5WIND CALCULATION
The Wind Calculation feature computes winds aloft by comparing Ground Speed and Track with
indicated heading, indicated air speed and Outside Air Temperature.
> ‘MENU’ 1 sec. + “CALCULATOR” + ‘ENTER’ + “WIND CALCULATION” + ‘ENTER’
User data is entered in the fields at the bottom half of the screen. To set Wind Calculation parameters
use ‘ENTER’ to edit the selected field (a box appears around the active field) and the cursor key to
move between fields. Press ‘CLEAR’ to return to Calculator menu.
Note
This function works best when the airplane is straight and level.
Wind Calculation is a full screen page with the following structure:
59
Fig. 10.5 - Wind Calculation page
The EKP-IV computes wind velocity and direction from the information entered above and from
the current Ground Speed,Track and Altitude, which are derived from GPS data. ETE to Waypoint
is also based on GPS Ground Speed and Track. Wind information will be recomputed when the
heading, air speed, air temperature or Altitude values are edited.
Note
The wind calculator does not correct for local barometric pressure, which may not be known accurately enroute.
The values produced by the wind calculator may therefore differ from the true winds by up to 5%.
10.6FUEL CONSUMPTION
The EKP-IV computes Fuel Consumption for each leg of the active Flight Plan or the fuel used in
flight, based on entries made by the pilot. This is a useful feature for flight planning purposes. Actual
Fuel Consumption will vary based on flight conditions and engine settings.
Fuel can be calculated in pounds, liters or gallons; the units of measure used for the valuesentered
here are selected from Units Setup menu in the System Setup Menu (see Par. 14.5).
> ‘MENU’ 1 sec. + “CALCULATOR” + ‘ENTER’ + “FUEL CONSUMPTION” + ‘ENTER’
CARBURANTE” + ‘ENTER’
60
Fig. 10.6 - Fuel Consumption page
To set Fuel Consumption parameters use ‘ENTER’ to edit the selected field (a box appears around
the active field) and use the cursor key to move between fields. Press ‘CLEAR’ to return to the
Calculator Menu. If your current Ground Speed is over 20 Knots, the EKP-IV will display “Actual GS”
and will not allow you to edit the value.
The EKP-IV will compute and display Fuel Consumption for each leg of a Flight Plan, and total fuel
needed for the flight in the Flight Plan page (see Chapter 6). When selected for display, the data
fields window will provide information on the flight time remaining before the reserve fuel has
been reached.
Note
The Fuel Consumption represents calculated fuel use based on user data. The reserve does not represent actual
fuel available in the aircraft.
Fuel Consumption can be modified en route by increasing or decreasing the fuel burn rate to match
actual usage. The new fuel computation will be averaged over the full distance and provide a good
estimate of fuel remaining. When refueling en route, combine the amount of new fuel and the
remaining fuel to enter the new “Starting Fuel” total for true computation of To Reserve data.
Note
Fuel calculations are only as accurate as the entries made. Always double-check fuel calculations.

15 Operating Requirements
The EKP-IV must be connected to a 10–35 V DC power source and the antenna requires a clear
view of the sky in order to operate.
Fig. 15 - I/O Connector
Note
The cable that ends with wires is available as an optional part. Please contact your local C-MAP office for details.
15.1ANTENNA ASSEMBLY & PLACEMENT
The antenna comes with a 5 meter cable with a SMB connector. The antenna is designed for use
inside the aircraft. It can be temporarily mounted on the aircraft’s dashboard using the included
velcro strip.
The antenna must have a clear view of the sky in order to receive satellite signals. GPS uses “line
of sight” signals to locate and track satellites. If the signals are obstructed by dense objects such as
aluminum, steel or even heavy ice, the EKP-IV will not operate properly.
Signals may also be blocked by heated wind screens (fiberglass, plexiglass and other plastics are
nor-mally transparent to GPS signals).
The antenna can be mounted to any convenient surface that has a clear view of the sky. If you
find that the EKP-IV does not locate and track satellites quickly or consistently, move the antenna.
Moving the location of the antenna a few inches often provides a better view of the sky.
15.2SECURING THE EKP-IV
The EKP-IV was designed to be mounted on your leg for operation. This will put the EKP-IV close at
hand and in an easily visible location without interfering with other equipment.
Use the elastic strap provided to secure the EKP-IV to your leg. Position the elastic strap around
your leg with the long looped strip on top. Fasten with the hook and loop closure at each end of
the strap. Hold the EKP-IV over the strap on your leg and lower into place.
Press down a little to be sure the strips are secure. If you prefer there are after market mounts
available for attachment to the yoke assembly or the seat rail tracks. Please contact your dealer for
more details on these items.
Note
Yoke mounts may not be appropriate for your aircraft. Use care to ensure that the EKP-IV does not obscure the
primary instruments.

15.4INSERT / CHANGE BATTERIES
Note
High capacity NiMh rechargeable batteries are needed.DO NOT use non rechargeable alkaline batteries. The unit
provides a ‘trickle’ charge to the batteries when the unit is plugged into external power and powered ON. In case
you power the EKP with batteries, you need to recharge them later with external charger.
15.5TROUBLESHOOTING
The following is a brief guide to some of the problems you may experience while using the EKP-IV
with common solutions.
15.5.1Power
No Power — The power connections are loose or not fully engaged. Make sure all Power Cable
connections are secure. Make sure the power supply is operating properly. Check the fuse located
at the end of the cigarette plug. (To open unscrew the middle circle at the tip of the adaptor.)
15.5.2GPS Fix
Position fix doesn’t change — The signal from one or more satellites has been lost; the positioning
information displayed is the most recent available.
Position fixes vary a lot — GPS accuracy is affected by several variables, the most prevalent of
which are the geometric quality of the fix. Therefore, the specified accuracy of 15 Meters RMS
in 2D is statistical, not absolute and assumes the absence of Selective Availability which was
discontinued in April 2000.
The EKP-IV is not obtaining position fixes — If the EKP-IV is using an internal GPS Receiver,
proceed to the GPS status screen:
>‘MENU’ 1 sec. + “GPS PAGE” + ‘ENTER’
Review the number of satellites in use. If zero, check that the antenna has a clear view of the
80
sky and that the connections have been made properly. If less than four satellites are in use, the
GPS receiver may have difficulty receiving a fix. Try repositioning the antenna. A GPS fix requires
a minimum of three satellites and a poor Signal Quality on one or more satellites may preclude
receiving a position fix.
Verify the user setting for Fix Source is listed as Internal GPS:
> ‘MENU’ 1 sec. + “SYSTEM SETUP” + ‘ENTER’ + “FIX SETUP” + ‘ENTER’ + “FIX
SOURCE” + ‘ENTER’ + “INTERNAL GPS” + ‘ENTER’
If the EKP-IV is using an External GPS receiver, proceed to Fix functions screen:
> ‘MENU’ 1 sec. + “SYSTEM SETUP” + ‘ENTER’ + “FIX SETUP” + ‘ENTER’
Verify that the Fix Source is listed properly (External NMEA) as indicated in the System Setup section
(see Chapter 14) and that the Baud Rate is set correctly for your GPS receiver (the EKP-IV requires
9600- Baud Rate). Verify that the data cable connections are proper.
External device is not responding — The data port is not turned on or is not outputting messages
in the correct format. Refer to the external device’s user guide to determine the correct message
format. Check the Installation Settings menu and make any necessary changes. The EKP-IV may
not be properly connected to the external device. Check all connections to be sure they are
correctly made and secure.
Navigate feature does not work — Blanks are displayed in the navigation data fields until a GPS
fix has been obtained; this usually occurs within a few Minutes. Also a Flight Plan must be active
to display values for navigation-related information (such as Cross Track Error) and you must be
travelling at least 2 Knots to display values for velocity-related information (such as GS). Activate
a Flight Plan and/or increase your speed.
Fluctuations in positioning and navigation data — Small fluctuations in positioning and velocityrelated navigation is normal.
15.5.3When Nothing Else Works
The list above should allow you to solve most of the operating problems you are likely to encounter.
Simply disconnecting the EKP-IV from power for a moment may solve your problem as well. If this
does not help, try resetting the EKP-IV to the factory defaults:
> ‘MENU’ 1 sec. + “SYSTEM SETUP” + ‘ENTER’ + “FACTORY DEFAULTS” + ‘ENTER’
If this does not help, you can try one additional memory clear option. This is a factory default
RAM Clear that should only be tried after all other attempts have been made. When using the
RAM Clear feature, you will loose all user stored information and the EKP-IV will default to factory
settings. Before this step, you have the option of saving user Marks, Track history and Routes to a
User Compact Flash (this is an optional purchase from your dealer). To perform a RAM Clear see
Par. 15.5.1.
15.5.4Customer Support
If you are unable to solve your operation problems, please contact C-MAP Aviation at 133 Falmouth
Road Mashpee, MA 02649, 508-539-3115 or 800.363.2627, reporting the Software Release and

Appendix B - MAP DATUM
A map datum is a mathematical description of the earth or a part of the earth and is based on the
ellipsoid or the arc of an ellipsoid that most closely represents the area being described. In addition,
the datum is centered at a specific location (the datum origin). A datum may describe a small
part of the earth, such as California or Iceland or may describe the entire earth, such as WGS84,
depending on which ellipsoid or ellipsoidal arc is selected.
87
Since datums use different ellipsoids and origins, the LAT/LON coordinates of the same position
differs from one datum to another. The difference may be slight or great, depending on the datums
involved, but will affect the apparent accuracy of the positioning information provided by a GPS
receiver. GPS (and all of the EKP-IV cartridges) use the WGS84 datum, which is the model of the
earth that is the closest possible average of the planet as a whole. Your chart datum is usually found
in the legend. If the datum is not WGS84 means that position coordinates determined with the
EKP-IV may not appear to agree with coordinates determined from a printed chart.
Appendix C - ICAO codes
The EKP-IV Database of airports is drawn from the system of ICAO (International Civil Aviation
Organization) identifiers. Unlike the IATA (International Airline Transport Association) identifiers
seen on charts and luggage tags, the ICAO codes minimize the possibility of duplicate identifiers
and allow pilots to identify an airport’s region and nearby large city. ICAO codes for international
airports use a 2-character identifier for the region, followed by 1 character that identifies the
airport’s general area, then 1 character of the airport.
For example, the ICAO code for Melbourne, Australia is YMML (IATA code MEL). All of Victoria and
Tasmania are in the YM region and the international airports in the Melbourne area start with “M”.
Therefore, Melbourne International Airport is YMML and the nearby Moorabbin Airport is YMMB.
In North America, the region containing Los Angeles begins with a “K” and the airport identifier of
L.A. International Airport is “KLAX”. Merrill Field in Anchorage, Alaska, begins with region code PA;
its identifier is PAMR.
The ICAO codes for the hundreds of smaller airports around the world whose names include
numbers are not preceded by a region prefix. For example, Barrie Executive Airport in Barrie,
Ontario, Canada is NA3.
The following pages contain maps and a table of ICAO codes. The map of the continental U.S.
contains the 2-character codes that identify the U.S. (“K”) and the area (the following number). The
world map shows the region codes only. The ICAO codes in the table are 2-character codes; like
“K2” and similar ICAO codes for the U.S., these codes identify both region (the first character) and
a geographical area within the region (the second character). Where necessary, the geographical
area or nearest nation is also included in parentheses. Please note that these regions and nations
are provided for loca-tion only and do not necessarily indicate possession by the nation indicated.
All areas are as described by the standard ARINC 424 format.
A list of worldwide ICAO codes is also available in book form from the International Civil Aviation
Organization. Ask for ICAO Location Indicators, document number 7910/70.
