FAA APPROVED
4) South of 55° South latitude between longitude 120° E and 165° E
Loss of the G500H heading and attitude may occur near the poles, but this will
not affect the GPS track.
1.5 AHRS Operation
The GRS 77 AHRS used in the G500H uses GPS data, air data, and
magnetometer inputs to improve availability. The GRS 77 will operate in
reversionary modes that do not require these inputs.
When operating in no magnetometer or no magnetometer/no air data modes
rapid pitch or roll movements may result in temporary loss of attitude indication.
1.6 Airspeed Limitations and Indicator Markings
The original type design approved airspeed limitations remain in effect. The
airspeed limitations stated in the AFM/POH, standby airspeed indicator and/or
airspeed limitation placards must be observed.
The airspeed markings on the G500H PFD match those on the standby indicator
(if installed) regardless of operating altitude. This rotorcraft was originally
equipped only with a placard for determining maximum airspeed based on
altitude; that placard remains as the means to determine maximum airspeed.
1.7 Navigation Angle
The GDU 620 Navigation Angle, which defines whether the GDU 620 headings
are referenced to True or Magnetic North can be set to either True or Magnetic
on the AUX page. The Navigation Angle set in the GDU 620 shall be set by the
pilot to match that which is set on all GPS/SBAS navigators interfaced to the
unit.
1.8 Helicopter Synthetic Vision Technology (HSVT)
Helicopter Synthetic Vision Technology (HSVT) is for situational awareness
ONLY. The use of the synthetic vision display alone for aircraft control,
navigation, or obstacle/terrain/traffic avoidance is prohibited.
1.9 Terrain and Obstacle Display
Terrain elevation information can be selected for display on the MFD as red,
orange, yellow, green, and black tiles. Obstacle and wire information is
displayed in red, yellow, and gray towers (obstacles). The information is
depicted for advisory purposes only and shall not to be used for aircraft
maneuvers or navigation. Terrain HSVT alerts are not equivalent to warnings
provided by HTAWS.
The terrain display is intended to serve as a situational awareness tool only. By
itself, it may not provide either the accuracy or the fidelity on which to base
decisions and plan maneuvers to avoid terrain or obstacles.
1.10 Moving Map
RFMS Garmin G500H as installed in Bell 206L-1
FAA APPROVED
190-01150-16 Rev. D
Page 7 of 25
The moving map on the MFD is advisory in nature and is shall not be used for
course guidance. The moving map on the MFD must be cross checked for
correctness against the PFD HSI, published charts, or other approved sources of
navigation information.
1.11 Datalinked Weather Display (XM, GFDS, FIS-B weather)
This limitation applies to datalinked weather products from SiriusXM via a GDL
69/69A, FIS-B via a Garmin ADS-B receiver, and Connext via a GSR 56.
Do not use data link weather information for maneuvering in, near, or around
areas of hazardous weather. Information provided by data link weather products
may not accurately depict current weather conditions.
Do not use the indicated data link weather product age to determine the age of
the weather information shown by the data link weather product. Due to time
delays inherent in gathering and processing weather data for data link
transmission, the weather information shown by the data link weather product
may be significantly older than the indicated weather product age.
Do not rely solely upon data link services to provide Temporary Flight
Restriction (TFR) or Notice to Airmen (NOTAM) information. Not all TFRs and
NOTAMS may be depicted on the G500H.
1.12 Traffic Display
Traffic may be displayed on the G500H System when connected to an approved
optional TCAS, TAS, TIS, or ADS-B traffic device. These systems are capable
of providing traffic monitoring and alerting to the pilot. Traffic shown on the
display may or may not result in traffic alerts. The display of traffic is an aid to
visual acquisition and shall not be utilized for aircraft maneuvering.
CAUTION
Some TAS systems may not automatically transition to operate mode upon
becoming airborne or may remain in standby mode if power to the TAS
system is cycled in the air. The pilot must be aware of the operating status
of the TAS traffic system by referring to the traffic icon on the map pages
or the status annunciator on the traffic page. If the traffic system is in
STANDBY mode use the traffic page softkeys to change to the OPERATE
mode.
1.13 Surface Operations
SafeTaxi or Chartview functions shall not be used as the basis for ground
maneuvering. SafeTaxi and Chartview functions do not comply with the
requirements of AC 20-159 and are not qualified to be used as an airport moving
map display (AMMD). SafeTaxi and Chartview use is limited to airport surface
orientation to improve flight crew situational awareness during ground
operations.
1.14 MFD Video Display
Video images displayed on the MFD are intended for use as an aid to situational
awareness only. Aircraft maneuvering based solely on the MFD video display is
prohibited.

Section 2. NORMAL PROCEDURES
Refer to the Garmin G500H PFD/MFD System Cockpit Reference Guide P/N
190-01150-03 or G500H Pilot’s Guide P/N 190-01150-02, for detailed operating
procedures. This includes all Primary Flight Display and Multi-Function Display
information.
Although intuitive and user friendly, the G500H PFD/MFD System requires a
reasonable degree of familiarity to avoid becoming too engrossed at the expense
of situational awareness. Pilots should take full advantage of training tools to
enhance familiarity with the G500H system.
2.1 PFD Knob & PFD Soft Keys
The basic PFD controls are adjacent to and beneath the PFD display. The rotary
knob performs the function annunciated on the display just to the upper left of
the HSI: HDG, CRS, ALT, V/S, or BARO. If no function is annunciated, the
knob is providing a HDG function. Assigning the function of the knob is done by
pressing/releasing one of the dedicated function buttons adjacent to the PFD.
The knob defaults back to HDG if it is not rotated for a period of 10 seconds.
The Garmin G500H PFD/MFD System Cockpit Reference describes each
function and its operation.
The soft keys at the bottom of the PFD display are used to configure the course
data displayed in the HSI (CDI button, 1-2 button) and select the optional
bearing pointers (BRG1 and BRG2 button) which may be overlaid in the HSI
presentation on the PFD. The soft keys operate by press and release.
The ATT SYNC soft key synchronizes the miniature aircraft symbol to the
horizon line at the time it is pressed. Pressing the soft key again will return the
miniature aircraft symbol to its zero reference. When ATT SYNC is active
small marks will appear at the outboard edges of the attitude display that show
the zero reference.
The units and markings on the PFD are not user configurable. They match the
units as specified in the aircraft’s FAA approved Rotorcraft Flight Manual and
standby instruments. Display and control of the airspeed references are made via
the AUX page of the MFD; consult the Garmin G500H Cockpit Reference
Guide for description and operation of these references.
2.2 MFD Knobs & MFD Soft Keys
The MFD controls are adjacent to and beneath the MFD display. The rotary
knobs are used to scroll through various pages/page groups of the MFD.
Pressing the knob will activate a cursor and allow for the user to enter data and
manipulate settings.
Soft keys at the bottom of the display allow for the rapid selection of pre-defined
functions to be performed on each page. The soft keys operate by press and
release. More detailed configuration is typically available by pressing the MENU
button, located on the right side of the display.

Pressing and holding down the CLR key will display the main map page on the
MFD. Details of the functions available on the MFD are explained in the Garmin
G500H Cockpit Reference Guide.
2.3 Helicopter Synthetic Vision Technology (HSVT)
The HSVT function may be turned on or off, as desired. To access the HSVT
soft key menu, press the PFD soft key on the GDU 620, followed by the SYN
VIS soft key. Synthetic vision terrain, horizon headings, and airport signs can be
toggled on and off from this menu. Press the BACK soft key to return to the root
PFD menu.
2.4 HSVT Terrain
When the G500H has SVT enabled aural and visual terrain, obstacle, and wire
alerting will be provided by the Terrain HSVT function of the G500H system.
Terrain HSVT modes (normal, RP, and inhibit) can be selected via soft key on
the Terrain page on the G500H MFD.
2.5 Altitude Alerter
The Altitude Bug Setting will flash when approaching within 1000 feet of the
selected altitude, and an audio tone is played when approaching or deviating
within 200 feet of the selected altitude.

Section 3. EMERGENCY PROCEDURES
3.1 Loss of Electrical Power
In the event of a total loss of electrical power, the G500H system will cease to
operate and the pilot must utilize the standby instruments and visual references
to fly the aircraft.
Section 4. MALFUNCTION PROCEDURES
These procedures supersede those presented as markings or placards, or
documented in the aircraft’s FAA approved Rotorcraft Flight Manual as a result
of the installation of the G500H system. All other emergency procedures remain
in effect.
4.1 Primary Flight Display
If primary flight information (Heading, Altitude or Airspeed) on the PFD is not
available or appears invalid, utilize the standby instruments installed and visual
references as required.
4.2 AHRS Failure
A failure of the Attitude and Heading Reference System (AHRS) is indicated by
a removal of the sky/ground presentation, a red X over the attitude indicator, and
a yellow “AHRS FAILURE” shown on the PFD. A heading failure will also be
indicated.
1. Use visual references for aircraft control
2. Set course datum using CRS selection of the PFD knob
The Attitude, Heading and Reference System (AHRS) requires at least one GPS
or air data input to function properly. In the unlikely event that GPS data and air
data is not received by the AHRS, the system will not provide Attitude, Heading,
Altitude, or Airspeed information; however, if the PFD is receiving valid GPS
information, the reversionary data on the PFD provides GPS Track and GPS
Altitude data along with course information and deviations which are still valid
and may be used to navigate.
4.3 Heading Failure
Heading failure is indicated by replacement of the digital heading display with
amber “HDG” text and a red X.
If valid GPS ground track is available, it will automatically be displayed in place
of heading. The HSI heading bug and course pointer will continue to function
normally, using GPS ground track as a reference instead of magnetic heading.
If GPS track is not available:
1. Use standby compass for heading reference.

2.
Verify selected course using “CRS” button and PFD knob.
CAUTION
No directional references will be displayed on HSI. The
heading bug will be removed, and the course pointer will
remain fixed at the top of the HSI regardless of aircraft
heading. Course deviation indications will behave similar to a
traditional CDI. VOR deviations will be relative the selected
course with a TO/FROM indication. Localizer deviations will
not be affected by the selected course, and reverse sensing will
occur when tracking inbound on a localizer back course.
4.4 Air Data Computer (ADC) Failure
Complete loss of the Air Data Computer is indicated by a red X and yellow text
over the airspeed, altimeter, vertical speed, TAS and OAT displays. Some
derived functions, such as true airspeed and wind calculations, will also be lost.
1. Use Standby Altimeter, visual references, and secondary cues
4.5 GPS Data Failure
GPS data failure may be indicated by any or all of following:
 Loss of GPS course deviation information on HSI
 Amber “LOI” text on the HSI

Amber “NO GPS POSITION” text on the MFD moving map

Loss of waypoint bearing or distance information
Select alternate GPS source, if available, by pressing “1-2” softkey on
PFD.
If alternate GPS source is not available:
2. Select alternate navigation source using “CDI,” “1-2,” or “BRG”
softkeys on PFD, or refer directly to external navigation data.

4.6 Navigation Data Failure (VOR/LOC/GS/ADF)
Navigation data failure may be indicated by any or all of following:

Loss of course deviation information on HSI

Loss of glideslope/glidepath information on PFD

Loss of bearing pointer on HSI
1.
Select alternate navigation source using “CDI,” “1-2,” or “BRG”
softkeys on PFD, or refer directly to external navigation data.
4.7 Synthetic Vision
The synthetic vision display of terrain uses several data sources (GPS, terrain
database, attitude information, etc.) in order to accurately display terrain. If any
of these data sources become unreliable or unavailable, the display of synthetic
190-01150-16 Rev. D

terrain will automatically revert to the non-SVT PFD display of blue over brown.
If there is a discrepancy between actual terrain around the aircraft and terrain
shown on the SVT display, the display of synthetic vision should be turned off
manually.
To turn off SVT:
1. Press the “PFD” softkey on the PFD.
Press the “SYN VIS” softkey to turn off SVT.
4.8 Display Dimming
When operating at high Outside Air Temperatures, typically in excess of 20°C,
the GDU 620 display may automatically dim to reduce equipment temperatures.
The display will return to full brightness when operating temperatures are
reduced.
4.9 Warnings, Cautions, and Advisory Annunciations

GENERAL INFORMATION
Garmin G500H Flight Display System
Reference Garmin G500H PFD/MFD System Cockpit Reference Guide P/N
190-01150-03 for basic operational aspects of the system. For a complete
detailed explanation of all the G500H’s capabilities see the G500H Pilot’s Guide
P/N 190-01150-02.
The G500H Flight Display System consists of a Primary Flight Display (PFD)
and Multi-Function Display (MFD) housed in a single Garmin Display Unit
(GDU 620), an Air Data Computer (GDC 74H ADC) and Attitude and Heading
Reference Systems (GRS 77H AHRS).
The G500H interfaces with other installed systems in the aircraft, including
Garmin GPS/SBAS navigators, VHF navigation radios, datalinks, traffic
systems, weather radars, audio panels, video sources, and radar altimeters.
The G500H system can optionally provide Terrain Alerting functions and
display of Terminal Procedures.
The primary function of the PFD is to provide attitude, heading, air data and
navigation information to the pilot. The primary function of the MFD is to
provide data which will facilitate the pilot’s awareness with respect to
surrounding factors that may affect the overall conduct of the flight.
Figure 4 - GDU 620 Displays
The required standby instruments (altimeter and magnetic compass) are
completely independent from the PFD and will continue to operate in the event
the PFD is inoperative. These standby instruments should be included in the
pilot’s normal instrument scan and must be utilized if the PFD data is in
question.

System Power Sources
The G500H system depends on electrical power to function. The Garmin
Display Unit (GDU), Attitude and Heading Reference System (AHRS), and Air
Data Computer (ADC) are connected to the aircraft main bus.
The major components of the G500H are circuit breaker protected with resetable type circuit breaker available to the pilot. These breakers are located on the
overhead circuit breaker panel and are labeled as follows:
Circuit
Breaker
Label
Equipment
PFD
Garmin Display Unit
(PFD/MFD), GDU 620
AHRS
Attitude and Heading
Reference System
ADC
Air Data Computer
Pitot-Static System
The pitot-static system supplies pitot-static pressure to the GDC 74H, standby
altimeter, and standby airspeed indicator.
Databases
The G500H utilizes several databases. Database titles display in yellow if
expired or in question (Note: the G500H receives the calendar date from the
GPS, but only after acquiring a position fix.). Database cycle information is
displayed at power up on the MFD screen, but more detailed information is
available on the AUX pages. Internal database validation prevents incorrect data
from being displayed.
The upper Secure Digital (SD) data card slot is typically vacant as it is used for
software maintenance and navigational database updates. The lower data card
slot should contain a data card with the system’s terrain / obstacle information
and optional data including Safe Taxi, FliteCharts and ChartView electronic
charts.
The terrain databases are updated periodically and have no expiration date.
Coverage of the terrain database is between North 75° latitude and South 60°
latitude in all longitudes.
The obstacle database contains data for obstacles and wires that pose a potential
hazard to aircraft. It is very important to note that not all obstacles are
necessarily charted and therefore may not be contained in the obstacle database.
Coverage of the obstacle database includes the United States and Europe. This
database is updated on a 56-day cycle.

The Garmin SafeTaxi database contains detailed airport diagrams for selected
airports. These diagrams aid in following air traffic control instructions by
accurately displaying the aircraft position on the map in relation to taxiways,
ramps, runways, terminals, and services. This database is updated on a 56-day
cycle.
The Garmin FliteCharts database contains procedure charts for the coverage area
purchased. This database is updated on a 28-day cycle. If not updated within 180
days of the expiration date, FliteCharts will no longer function.
The Jeppesen ChartView electronic charts database contains procedure charts for
the coverage area purchased. An own-ship position icon will be displayed on
these charts. This database is updated on a 14-day cycle. If not updated within 70
days of the expiration date, ChartView will no longer function.
The airport directory database contains information on landing facilities, such as
operating hours, services available, and transportation/lodging resources.
Airport directory information may be available from multiple sources and
coverage areas. This database is updated on a 56-day cycle.
AHRS Operation
The GRS 77 AHRS used in the G500H uses GPS data, air data, and
magnetometer inputs to improve availability. The GRS 77 will operate in
reversionary modes that do not require these inputs.
When operating in no magnetometer or no magnetometer/no air data modes
rapid pitch or roll movements may result in temporary loss of attitude indication.
Airspeed Markings
The airspeed markings on the G500H PFD match those on the standby indicator
(if installed) regardless of operating altitude. This rotorcraft was originally
equipped only with a placard for determining maximum airspeed based on
altitude; that placard remains as the means to determine maximum airspeed.
Navigation Sources
The G500H requires at least one Garmin GPS/SBAS navigation unit to be
installed to ensure the integrity of the Attitude and Heading Reference System.
The AHRS will still operate in reversionary mode if all GPS sources fail, and the
PFD attitude display will still be presented.
The HSI on the G500H can display course deviation information from up to four
sources: GPS 1, GPS 2, VLOC 1, or VLOC 2. In addition, the HSI can display
two simultaneous bearing pointers sourced from GPS 1, GPS 2, VLOC 1, VLOC
2.
Course Pointer Auto Slewing
The G500H HSI will auto slew, i.e. automatically rotate the GPS course pointer
to the desired course defined by each GPS leg. The system will also auto slew
the VHF NAV course pointer when the CDI transitions to a LOC setting if an

ILS, LOC, LOC BC, LDA, or SDF approach is activated in the GPS/SBAS
navigator.
The VHF NAV (green) course pointer will only auto slew if the approach is
active in the navigator, the LOC frequency is loaded in the active NAV
frequency, and then the HSI source is changed to the corresponding VHF NAV
for the approach. Back Course approaches will auto slew to the reciprocal
course.
The system is not capable of automatically setting the inbound VHF NAV course
pointer if an approach is not active in the GNS Navigation System.
The pilot should always double check the inbound course pointer prior to
initiating any transition on any VHF NAV approach. Auto slewing the VHF
NAV course pointer to the correct selected course is a database dependent
function.
Helicopter Synthetic Vision Technology (Optional)
HSVT uses an internal terrain database and GPS location to present the pilot
with a synthetic view of the terrain and obstacles in front of the aircraft. The
purpose of the SVT system is to assist the pilot in maintaining situational
awareness with regard to the terrain and traffic surrounding the aircraft. A typical
HSVT display is shown below:
Figure 5 - Typical HSVT Display
HSVT provides additional features on the G500H primary flight display (PFD)
which include the following information:
 Synthetic Terrain; an artificial, database derived, three dimensional
view of the terrain ahead of the aircraft within a field of view of
approximately 25 degrees left and 25 degrees right of the aircraft
heading.


Obstacles; obstacles such as towers, including buildings that are within
the depicted synthetic terrain field of view.

Flight Path Marker (FPM); an indication of the current lateral and
vertical path of the aircraft. The FPM is displayed when synthetic
terrain is selected for display and ground speed is more than 30 knots.

Horizon Line; a white line indicating the true horizon is always
displayed on the SVT display.

Horizon Heading; a pilot selectable display of heading marks
displayed just above the horizon line on the PFD.

Airport Signs; pilot selectable “signposts” displayed on the synthetic
terrain display indicating the position of nearby airports that are in the
G500H database.

Runway Highlight; a highlighted presentation of the location and
orientation of the runway(s) at the destination airport.

Traffic (Optional); a display on the PFD indicating the position of
other aircraft detected by a traffic system interfaced to the G500H
system.
The synthetic terrain depiction displays an area approximating the view from the
pilot’s eye position when looking directly ahead out the windshield in front of
the pilot. Terrain features outside the field of view are not shown on the display.
The synthetic terrain display is intended to aid the pilot awareness of the terrain
and obstacles in front of the aircraft. It may not provide either the accuracy or
fidelity, or both, on which to solely base decisions and plan maneuvers to avoid
terrain or obstacles. The synthetic vision elements are not intended to be used for
primary aircraft control in place of the primary flight instruments.
Depiction of Obstacles and Wires
Dedicated Terrain Page
The dedicated Terrain page will always depict point obstacles at zoom scales of
10 nm or less and depict wire obstacles at zoom scales of 5 nm or less. The
obstacle or wire overlay icon, shown below, will be shown near the bottom of
the display when the obstacle or wire depiction is active based on the zoom
scale.
NOTE
The Obstacle or Wire Overlay Icon is displayed when wires
or obstacles will be available on the Terrain Page based on
the zoom scale. Only obstacles and wires within 2,000 ft
vertically of the aircraft will be drawn on the Terrain Page.

INTERFACED EQUIPMENT
GTN 6XX or 7XX Series Navigator
The G500H requires an approved navigator such as a GTN 6XX/7XX or GNS
400W or 500W series navigator. The G500H can display annunciations
received from the navigators.
Audio Panel
The G500H Avionics Display System is interfaced with the audio panel installed
in the rotorcraft to provide aural altering generated by the G500H.
Traffic Display
The G500H system can display traffic data from interfaced traffic systems.
Sources of traffic data include TIS-A traffic via the Garmin GTX Series Mode-S
Transponders, TAS/TCAS traffic from various active traffic awareness systems,

and ADS-B traffic from Garmin ADS-B transceivers. The information from
these systems is displayed on and controlled using the MFD.
Weather Data
The G500H system can display weather data from interfaced datalink systems.
Sources of weather data include the Garmin GDL69 and GDL69A Sirius XM
receivers, Garmin GSR 56 Iridium Transceiver, and Garmin GDL 88 ADS-B
transceiver. If one of these optional weather datalink receiver is installed, the
pilot will be able to access graphical and text weather products using the MFD.
Textual weather products may not be available in all regions of the world.
Video Display
The G500H can display images from up to 2 video inputs. Video images are
displayed on the MFD. The G500H does not provide a means to control the
video source; however the digital images from the video source can be adjusted
using the G500H.
Radar Altimeter
The G500H supports the display of radar altitude on the PFD from certain radar
altimeters.
High Speed Data Bus Interface
Some Garmin equipment connected to the G500H system utilizes the High
Speed Data Bus (HSDB) interface. HSDB is similar to an Ethernet bus and
provides a high-speed interface between Garmin avionics. Like Ethernet, data
between two units may be passed through intermediate “hub” units. Interfaced
equipment that uses HSDB includes the GTN 6XX/7XX navigators, GDL 69
datalink receiver, GDL 88 ADS-B transceiver, and GTS 8XX traffic systems.
The HSDB interfaces are installed to so that maximum data path redundancy is
achieved. However, depending on the number of HSDB units installed, failure
of one HSDB unit may result in loss of data on the G500H from “downstream”
HSDB units. Any loss of data will be annunciated on the G500H.
HTAWS Annunciations on the PFD [from a Garmin navigator]
The G500H will display HTAWS (Helicopter Terrain Awareness and Warning
System) annunciations on the PFD if the G500H is interfaced to a Garmin
navigator with integrated HTAWS as GPS 1. The required HTAWS
annunciations appear in the upper right of the PFD.
HTAWS alerts on the PFD of the G500H System are only displayed from the
GPS/TAWS navigator interfaced as GPS 1 and are displayed regardless of the
system 1-2 setting, which drives all other PFD and MFD data used by the
G500H.

ADS-B Traffic System Interface
The G500H system can be interfaced to sources of ADS-B traffic. The nose of
the ownship symbol on both the G500H main map page and dedicated traffic
page serves as the actual location of your aircraft. The center of the traffic target
icon serves as the reported location for the target aircraft. Motion vectors for
traffic may be displayed in either absolute or relative motion. The location of
the traffic targets relative to the ownship are the same, regardless of the selected
motion vector.
Absolute motion vectors are colored white and depict the reported track of the
traffic target referenced to the ground. An absolute motion vector pointed
towards your ownship symbol does not necessarily mean the traffic target is
getting closer to your aircraft.
Relative motion vectors are colored green and depict the motion of the traffic
target relative to your ownship symbol. The direction the traffic target is pointed
may vary greatly from the motion vector and a target may be getting closer to
your aircraft independent of the direction the target is pointed. A green relative
motion vector pointed towards your ownship indicates that the traffic target is
converging on your aircraft.
Traffic targets displayed on the dedicated traffic page may be selected using the
MFD knobs in order to obtain additional information about a traffic target.Flight
Plan
The Flight Plan shown on the GDU 620 is the same as that provided by the GPS
navigation source selected on the PFD. When waypoints are removed from the
Flight Plan on the GPS navigator or when the entire flight plan is deleted it may
take as long as 20 seconds for the change to be reflected on the G500/600 Flight
Plan page and map.
