original by the selected distance. The original course line will be drawn in gray.
The aircraft will navigate to the parallel track course line and external CDI/HSI
guidance will be driven from the parallel track.
When you reach the end of the flight plan, a message will state, “Parallel
offset terminating in X seconds.” The message will be given when the aircraft
reaches the offset distance from the end of the parallel track. This will give the
pilot sufficient time to intercept the original course.

PROCEDURES
Foreword
The GTN 7XX allows you to fly non-precision and precision approaches to
airports with published instrument approach procedures. The system can also
provide visual approach guidance to most airports. Approach procedures are not
the same as the approach plates available in ChartView or FliteCharts, which are
separate databases.
The Procedures Page is displayed by touching the PROC key on the Home
page. The Procedures Page provides access to approaches, departures and
arrivals. Selections are also shown to: Activate Approach, Vectors to Final, and
Activate Missed Approach.
NOTE: With the exception of Charted Visual Flight Procedures (CVFPs),
visual approaches do not have associated approach charts.

Proc
Charts
NOTE: The Chart feature provides a digital representation of a paper
chart and provides no vertical or lateral course guidance. Flight Plan and
Procedures are separate from Charts, and do provide vertical and lateral
course guidance for the loaded route or procedure shown on the Flight
Plan page. The term “Chart Unavailable” means that the chart cannot be
viewed on the Charts due to either a chart not being published, or an error
in the Chart database, but does not preclude its availability or inclusion of
the procedure in the Flight Plan or Procedures portion of the system. The
absence of a chart for a particular Departure, Arrival, or Approach does
not preclude its availability or inclusion in the Flight Plan or Procedures
portion of the system. The absence of a particular Departure, Arrival, or
Approach under the Flight Plan or Procedures portion of the system does
not preclude the ability to view the Chart for that procedure under the
Chart feature.
NOTE: Baro-corrected altitude is not required by the GTN unit to meet
the requirements of TSO-C146c; however, to take full advantage of
the GTN unit's capabilities, an optional baro-corrected altitude source
is recommended for automatic sequencing of altitude leg types. If no
baro-corrected altitude data is provided to the GTN unit, altitude leg types
must be manually sequenced.

Basic Approach Operations
The GTN 7XX provides lateral and, when appropriate, vertical guidance
for visual and GPS/RNAV approaches. The moving map pages can also be used
as an aid to situational awareness for ILS, VOR, and NDB approaches (and
non-precision localizer-based approaches), but the appropriate radio navigational
aid MUST be used for primary approach course guidance for non-GPS approaches.
Approaches designed specifically for GPS are often very simple and don’t require
overflying a VOR or NDB. Currently, many non-precision approaches have “GPS
overlays” to let you fly an existing procedure (VOR, VOR/DME, NDB, etc.) more
accurately using GPS.
Many overlay approaches are more complex (in comparison to GPS-only
approaches). The GTN 7XX displays and guides you through each leg of the
approach — automatically sequencing through each of these legs, up to the missed
approach point (MAP). Approaches may be flown “as published” with the full
transition — using any published feeder route or initial approach fix (IAF) — or
may be flown with a vectors-to-final transition.
Phase of flight annunciations are provided on the bottom of the display
indicating the current mode of flight.
Procedures are arranged around the existing flight plan in the following order:
Departure, En Route, Arrival, and Approach. For example, Departure waypoints
are inserted before the En Route waypoints in the flight plan and Arrival waypoints
are inserted between the En Route waypoints and the approach waypoints. Always
verify that the transition waypoints between each phase are correct.

Visual Approach Procedures
Foreword
NOTE: This feature is available in software v6.30 and later. Not all airports
in the database support visual approaches.
The GTN generates visual approaches, providing advisory horizontal and
optional vertical guidance for the selected runway. Advisory guidance aids in
the performance of a stabilized approach and ensures the aircraft is in line with
the destination runway.
There are three different methods for loading and activating visual approaches.
Method 1: Select the Visual key on the map. When the aircraft is within
10 NM of the destination airport the Visual key displays. For information about
key configuration, refer to "Visual Approach Selector".

For both methods, pressing the Visual key prompts a list of available visual
approaches. Once selected, the visual approach immediately loads and becomes
active.
Method 3: Visual approaches load from the PROC - Approach page or the
Airport Info - Procedures tab (similar to published instrument approaches). For
information on how to use this page, refer to section 6.4.
After a visual approach loads, a confirmation pop-up prompts, detailing
the glidepath angle (GPA) and threshold crossing height (TCH) when vertical
guidance is available. When unavailable it reads, "NO VERTICAL GUIDANCE."

GTN 725/750 Pilot’s Guide
190-01007-03 Rev. P
The availability of vertical guidance advisories for visual approaches is
dependent on terrain and obstacle obstructions along the approach path.
If no known obstructions are within the approach path, vertical guidance is
provided to a maximum distance of 28 NM from the runway. If there are known
obstructions further than 3 NM, but within the 28 NM maximum distance from
the runway along the approach, vertical guidance is limited to the approach path
portion after crossing the known obstructions. This is indicated by the shortened
magenta line on the map after loading the approach. If obstructions are within
3 NM to the runway, along the approach path, advisory vertical guidance is not
provided. Lateral guidance is always provided for visual approaches.
Published data is used to determine the visual approach GPA and TCH for
the selected runway. If no published data is available, the default is 3º GPA and
50 FT TCH.
NOTE: If the GTN does not have a valid terrain database, advisory vertical
guidance is not available for visual approaches.
NOTE: Only external CDI/VDI displays provide vertical deviation indications.

• When flying a localizer-based approach (other than backcourse) with
automatic CDI switching enabled:
1. “GPS” guidance may be used while flying outbound and on
the initial portion of the procedure turn.
2. “VLOC” guidance is used on the remainder of the approach
from the time you turn inbound on the procedure turn.
3. The localizer frequency must be active to use “VLOC” guidance
at the MAP.
• When flying a localizer-based approach with automatic CDI switching
disabled:
1. You may select “VLOC” guidance at any point on the approach
prior to reaching the FAF.
2. The localizer frequency must be active to use “VLOC” guidance.

CHARTS
Foreword
NOTE: The availability of SafeTaxi, ChartView, or FliteCharts in electronic
form may not preclude the requirement to carry paper charts aboard the
aircraft. See the AFMS for more information.
NOTE: The Chart feature provides a digital representation of a paper
chart and provides no vertical or lateral course guidance. Flight Plan and
Procedures are separate from Charts, and do provide vertical and lateral
course guidance for the loaded route or procedure shown on the Flight
Plan page. The term “Chart Unavailable” means that the chart cannot be
viewed on the Charts due to either a chart not being published, or an error
in the Chart database, but does not preclude its availability or inclusion of
the procedure in the Flight Plan or Procedures portion of the system. The
absence of a chart for a particular Departure, Arrival, or Approach does
not preclude its availability or inclusion in the Flight Plan or Procedures
portion of the system. The absence of a particular Departure, Arrival, or
Approach under the Flight Plan or Procedures portion of the system does
not preclude the ability to view the Chart for that procedure under the
Chart feature.

NOTE: Features that are selectable on the main map page, such as obstacles,
airports, airspace, and other waypoint types that are not visible beneath the
overlaid chart, remain selectable even when an approach chart is overlaid
on the main map.
NOTE: Do not use SafeTaxi or Chartview functions as the basis for ground
maneuvering. SafeTaxi and Chartview do not comply with the requirements
of AC 120-76C and are not qualified to be used as an airport moving map
display (AMMD). SafeTaxi and Chartview should only be used by the flight
crew to orient themselves on the airport surface.
The chart page will default to the nearest airport if no flight plan or destination
airport is present. While you are on the ground, the displayed charts will default
to the current airport location regardless of flight plan. The optional ChartView
and FliteCharts provide on-board electronic terminal procedures charts.
Electronic charts offer the convenience of rapid access to essential information.
Either ChartView or FliteCharts may be configured in the system, but not both.

The ChartView database is revised every 14 days. Charts are still viewable
during a period that extends from the cycle expiration date to the disables date.
ChartView is disabled 70 days after the expiration date and is no longer available
for viewing upon reaching the disable date. When turning on the GTN unit, the
Power-up Page indicates the criteria for ChartView availability. An enablement
card that is purchased from Garmin is separate from the Jeppesen database and
is required to enable ChartView. Jeppeson charts that do not contain a specific
effective date are effective upon receipt.

SafeTaxi®
SafeTaxi® is an enhanced feature that gives greater map detail when zooming
in on airports. The airport display on the map reveals runways with numbers,
taxiways with identifying letters/numbers, airport Hot Spots, and airport
landmarks including ramps, buildings, control towers, and other prominent
features. Resolution is greater at lower map ranges (zooming in). When the
aircraft location is within the screen boundary, including within SafeTaxi ranges,
an airplane symbol is shown on any of the navigation map views for enhanced
position awareness.
NOTE: Do not use SafeTaxi or Chartview functions as the basis for ground
maneuvering. SafeTaxi and Chartview do not comply with the requirements
of AC 120-76C and are not qualified to be used as an airport moving map
display (AMMD). SafeTaxi and Chartview should only be used by the flight
crew to orient themselves on the airport surface.
Designated Hot Spots are recognized at airports with many intersecting
taxiways and runways, and/or complex ramp areas. Airport Hot Spots are
outlined to caution pilots of areas on an airport surface where positional
awareness confusion or runway incursions happen most often. Hot Spots are
defined with a magenta circle or outline around the region of possible confusion.

Graphically Edit Flight Plan Mode
The Edit Flight Plan Mode allows making quick changes to the active flight
plan directly on the display. The process is simply touching the display to start
Map Pan Mode, touching the Graphically Edit FPL key, dragging the desired
leg to a new waypoint or airway, and touching the Done key. When graphically
editing the active flight plan leg, the active leg course and TO Waypoint will be
added to the flight plan as a Direct-To. At any point, a step may be removed by
touching the Undo key or the whole process ended by touching the Cancel key.
The Undo key will remove up to nine steps.
NOTE: It is not possible to graphically add an intermediate waypoint
between the current position and a Direct-To waypoint unless that waypoint
is in the flight plan. Garmin recommends deleting any flight plan prior to
graphically editing a Direct-To waypoint.

TCAS II
A Traffic Alert and Collision Avoidance System II (TCAS II), such as the
GTS 8000, improves flight safety by monitoring nearby airspace for aircraft flying
with operating transponders. The TCAS II system provides traffic information to
the displays. If separation from other aircraft is within certain limits, the system
issues Traffic Advisories (TAs) assisting the flight crew in the visual acquisition of
traffic, or Resolution Advisories (RAs) providing recommended vertical guidance
maneuvers to resolve traffic conflicts.
10.9.1
TCAS II Theory of Operation
When the TCAS II system is operating in TA/RA or TA Only Mode, the system
interrogates the transponders of other aircraft in the vicinity, and monitors for
their replies. Based on successive replies, the system tracks the range, bearing,
and (if reported) the altitudes of other aircraft. For each detected aircraft
transponder, the system calculates time to, and separation at, the closest point
of approach (CPA) around the potential collision area surrounding own aircraft.
Based on CPA time, own aircraft altitude, and selected TCAS II system mode,
the system determines if a TA or RA should be issued for a detected intruder.

Table 10-17 Altitude-based TCAS II TA/RA Alert Thresholds
Proc
The TCAS II system categorizes detected traffic into four groups of increasing
collision threat potential:
Charts
• Other Traffic (OT), displayed as a hollow white diamond, is not currently
a threat.
• Proximate Traffic (PT), displayed as a filled white diamond, is not
currently a threat, but is within 6 nm and ±1,200 feet of the own-aircraft
altitude.
• Traffic Advisory (TA), displayed as a filled yellow circle, indicates traffic is
within 20-48 seconds of a potential collision area. If a Traffic Map is shown,
and the TA traffic is beyond the selected map range, the system displays a
half-TA symbol at the edge of the map at the approximate relative bearing
of the TA traffic. If TA traffic subsequently meets the criteria for an RA, the
system will issue an RA.
• Resolution Advisory (RA), displayed as a filled red square, indicates
traffic is within 15-35 seconds of a potential collision area. If a Traffic
Map is shown, and the RA traffic is beyond the selected map range, the
system displays a half-RA symbol at the edge of the map positioned at the
approximate relative bearing to the RA traffic.

TCAS II with ADS-B
When the GTS 8000 TCAS II is in operating mode, it interrogates Mode-S
transponder data while automatically receiving ADS-B position and velocity
information directly from a comparably equipped aircraft target. The system
attempts to match (or “correlate”) the two surveillance data sources to increase
the preciseness of its target location. When a correlation is made, the system
displays the traffic information for the source determined to be the most
accurate. Any traffic that is not correlated (i.e., only detected by one system but
not the other) is also displayed for the flight crew. This may occur, for example,
if another aircraft is beyond the surveillance range of the TCAS II, but the
GTS 8000 is still receiving position and velocity information from other ADS-B
equipped aircraft. The traffic correlation feature improves the accuracy of the
traffic displayed, while reducing the occurrence of displaying a single target
twice.
NOTE: Aircraft that are surveilled by ADS-B In only will not trigger a TCAS
resolution advisory.

Resolution Advisories
Resolution Advisories (RAs) are TCAS II recommended vertical guidance
maneuvers to be flown to resolve a traffic conflict. If the targeted threat
aircraft is also TCAS II equipped, the two traffic systems use Mode S data
link interrogations to generate complimentary responses to the RAs. During
an RA event, the system monitors the performance and status of the aircraft
response. It may command an increase/decrease vertical speed, and/or reverse
climb/descend commands until the aircraft is clear of the conflict.
RAs are categorized in two resolution types: preventive and corrective:
Preventive Resolutions
Foreword
Getting
Started
Audio &
Xpdr Ctrl
Com/Nav
FPL
Direct-To
Preventive RAs are issued when the aircraft's present vertical speed will
resolve a traffic conflict. The system displays a range of vertical speed avoidance
limits. These limits are displayed to help the pilot from climbing or descending
into conflicting traffic.
Corrective Resolutions
Proc
Charts
Wpt Info
Corrective RAs are issued when the aircraft's present vertical speed will
not resolve a traffic conflict. The VSI indicates a range of vertical speeds to be
avoided,while the current vertical speed appears in white with a red background.
For advisory, the VSI indicates a green “fly to” vertical speed range that needs
to be flown to resolve the RA conflict. In some cases, the TCAS II system logic
determines it will be necessary to cross through the intruder aircraft’s altitude to
resolve the traffic conflict.
The following tables illustrate Preventive Advisories, Corrective Advisories,
and TCAS II Voice Alerts.

NEXRAD
WSR-88D, or NEXRAD (NEXt-generation RADar), is a network of
158 high-resolution Doppler radar systems that are operated by the National
Weather Service (NWS). NEXRAD data provides centralized meteorological
information for the continental United States and selected overseas locations.
The maximum range of a single NEXRAD radar site is 250 NM. The NEXRAD
network provides important information about severe weather for air traffic
safety.
NEXRAD data is not real-time. The lapsed time between collection,
processing, and dissemination of NEXRAD images can be significant and may
not reflect the current radar synopsis. Due to the inherent delays and the relative
age of the data, it should be used for long-range planning purposes only. Never
use NEXRAD data for maneuvering in, near, or around areas of hazardous
weather. Instead, use it in an early-warning capacity of pre-departure and en
route evaluation.

FIS-B Weather
Foreword
NOTE: FIS-B information is to be used for pilot planning decisions
and pilot near-term decisions focused on avoiding areas of inclement
weather that are beyond visual range or where poor visibility precludes
visual acquisition of inclement weather. FIS-B weather and NAS status
information may be used as follows:
(a) To promote pilot awareness of own ship location with respect to
reported weather, including hazardous meteorological conditions, NAS
status indicators, and enhance pilot planning decisions and pilot
near-term decision-making.
(b) To cue the pilot to communicate with the Air Traffic Control
controller, Flight Service Station specialist, operator dispatch, or airline
operations control center for general and mission critical meteorological
information, NAS status conditions, or both.
FIS-B information, including, weather information, NOTAMs, and TFR
areas, are intended for the sole purpose of assisting in long- and
near-term planning decision making. The system lacks sufficient
resolution and updating capability necessary for aerial maneuvering
associated with immediate decisions.
The Flight Information Services (FIS-B) function is capable of displaying text
and graphic weather information with GDL 88 and GTX 345 installations. No
subscription for FIS-B services is required.
The FIS-B Function is a graphic weather display capable of displaying
graphical weather information on UAT equipped installations. Graphical data
overlaid on the map indicates the rainfall detected by ground based radar for a
specific area. Color transitions from light green (light rainfall) to magenta (heavy
rainfall) represent an increase in precipitation. Review the Limitations section in
the front of this guide for the limitations that apply to the FIS-B data.

GPS Faults
The GTN communicates various fault conditions that can affect the accuracy
of the GPS. These include loss of integrity, loss of navigation, and a loss of
position.
Loss of Integrity
A loss of integrity is when the integrity of the GPS position does not meet the
requirements for the current phase of flight. This only occurs before the final
approach fix (if an approach is active).
The GTN indicates a loss of integrity by displaying the amber "LOI"
annunciation at the bottom of the screen.
Loss of Navigation
A loss of navigation can be caused by any of the following conditions:
• Aircraft is after the final approach fix and GPS integrity does not meet the
active approach requirements
Map
• Insufficient number of satellites supporting aircraft position (i.e., more
than 5 seconds pass without adequate satellites to compute a position)
Traffic
• GPS sensor detects an excessive position error or failure that cannot be
excluded within the time to alert
Terrain
• On-board hardware failure
Weather
The GTN indicates a loss of navigation by invalidating the active course
guidance, and issuing a system message describing the cause.

Resolving Database SYNC Conflicts
Foreword
Database conflicts must be resolved for synchronization to occur. Conflicts
exist when multiple LRUs have a database of the same cycle, but with different
regions or types (e.g., fixed wing vs. rotorcraft navigation database, different
regions of the navigation database, or different obstacle database types).
The GTN attempts to resolve these by automatically synchronizing the most
recently installed database across all other LRUs (software v6.30 and later). Pilot
intervention is required when conflicts cannot be resolved automatically. Conflicts
occurring with earlier software versions also require manual intervention.
To manually resolve database conflicts, touch the Resolve Conflicts key on
the display containing the desired database version. This key is located on the
Conflicts tab of the System Information page.
