GENERAL
The G500H TXi system is a display and sensor system which provides one or
more of the following functions:
•
Primary Flight Display (PFD) – Provides attitude, heading, air data and
navigation information to the pilot
•
Multi-Function Display (MFD) – Provides pilot awareness of factors
that may affect the overall conduct of the flight
The G500H TXi system consists of one or more of the following displays:
•
GDU 1060 – 10” PFD/MFD
•
GDU 700P – 7” Portrait PFD, MFD
•
GDU 700L – 7” Landscape PFD
PFD functions are supported by interfaced AHRS/ADC (either integrated or
external) and at least one GPS navigator. An optional GCU 485 controller
provides additional dedicated controls for PFD operation. Other PFD interfaces
may include VHF navigation radios and radar altimeter.
MFD functions are supported by GPS navigator interfaces and a variety of other
optional interfaces such as datalinks, traffic systems, and video sources.
GDU 1060
The GDU 1060 is a 10” PFD/MFD display. Each function is segregated into a
portion of the display. The MFD can be selectively hidden/shown with the PFD
expanding into the MFD space when the MFD is hidden.
GDU 700P
The GDU 700P is a 7” portrait display which provides a single PFD or MFD. In
some installations, a 700P display may provide backup PFD information in the
event that the primary PFD display fails or malfunctions.
GDU 700L
The GDU 700L is a 7” landscape PFD display.
AHRS / ADC
The AHRS and ADC sense rotorcraft attitude and air data to be used for display
to the pilot and for use by other installed systems. The AHRS and ADC are
remotely-mounted.
All AHRS units have a magnetometer interface for determining magnetic
heading. The AHRS also requires GPS and airspeed inputs to aid the system.
All ADC units have an OAT probe interface for measuring outside air
temperature.

Standby Instruments
PFD installations require standby altitude instruments and in some jurisdictions
standby airspeed and attitude instruments.
PFD Controller
An optional GCU 485 PFD controller may be installed to provide dedicated PFD
controls. Although control of all PFD functions is available using the GDU
knobs and touchscreen, the PFD controller provides dedicated knobs for
heading, altitude, vertical speed, airspeed, and BARO setting. Dedicated
buttons are also provided for CDI source selection.
Block Diagrams
The following diagrams illustrate the typical TXi installation. Due to the large
scalability of the TXi system, it is not practical to represent every possible
installation combination.

Software Version
GDU
PFD, MFD
2.30
NOTE
This section is not intended to be a comprehensive list of
approved software. It is intended to provide a means to
determine if this RFMS revision is applicable to the software
that is installed in the rotorcraft. Do not use this RFMS
revision if the installation has a software version less than that
shown in the Table above.
AHRS Operational Area
The AHRS used in the TXi Flight Display System is limited in its operational
area: AHRS operation is not assured north of 72N and south of 70S latitudes.
In addition, AHRS operation is not assured in the following four regions:
1) North of 65° North latitude between longitude 75° W and 120° W
2) North of 70° North latitude between longitude 70° W and 128° W
3) North of 70° North latitude between longitude 85° E and 114° E
4) South of 55° South latitude between longitude 120° E and 165° E
Loss of attitude and heading may occur near the poles and in areas where the
magnetic variation is greater than 99.9 degrees East or West.

FAA APPROVED
190-02401-02 Rev. 2
Page 10 of 43
ADAHRS and AHRS Normal Operating Mode
The Attitude and Heading Reference System integrity monitoring function
requires external GPS and Air Data to be provided to the AHRS. An ADAHRS
receives Air Data internally and therefore only requires external GPS.
NOTE
Attitude will remain valid if either GPS or Air Data is lost.
Sensor Selection
Do not select or operate on cross-side AHRS or ADC sensors (e.g. PFD 1 using
AHRS/ADC 2), unless directed to do so as part of an emergency or abnormal
procedure in this RFMS.
Synthetic Vision
The synthetic vision presentation must not be used as the sole reference for
rotorcraft control (without reference to the primary flight instruments).
The synthetic vision presentation must not be used as the sole reference for
navigation or obstacle/terrain/traffic avoidance.
If the installed HTAWS or Terrain Alerting system is inoperative, the synthetic
vision display on the PFD must be selected off.
HTerrain FLTA
HTerrain FLTA alerting shall only be inhibited when in visual contact with
terrain and when the pilot can be assured of maintaining clearance from terrain,
obstacles, and wires.
RP Mode shall only be used when in visual contact with terrain.
Airspeed Limitations
Display of power on VNE and power off VNE on the TXi corrects VNE for changes
in temperature and altitude but does not account for additional limitations to VNE
such as for weight, doors off, or external loads.
Standby airspeed indications do not account for changes to V NE due to changes
in weight, temperature, altitude or other factors.
The pilot must refer to the Rotorcraft Flight Manual to determine the correct V NE
for the current conditions and configuration.
Moving Maps
Moving map displays (ownship position relative to map features) must not be
used as the primary or sole means of navigation or course guidance.
RFMS, G500H TXi P27 AML STC
FAA APPROVED
190-02401-02 Rev. 2
Page 11 of 43
Terrain Display
Rotorcraft maneuvers and navigation shall not be predicated upon the use of the
terrain display.
The terrain display is intended to assist the pilot with maintaining awareness of
the proximity of terrain, obstacles, and wires to the rotorcraft. By itself, the
terrain display may not provide either the accuracy or the fidelity on which to
base decisions and plan maneuvers to avoid terrain, obstacles, or wires.
Datalink Products (SiriusXM, FIS-B, and Connext)
Do not use datalink weather information for maneuvering in, near, or around
areas of hazardous weather. Information provided by datalink weather products
may not accurately depict current weather conditions.
Do not use the indicated datalink weather product age to determine the age of
the weather information shown by the datalink weather product. Due to time
delays inherent in gathering and processing weather data for datalink
transmission, the weather information shown by the datalink weather product
may be significantly older than the indicated weather product age.
Do not rely solely upon datalink services to provide Temporary Flight
Restriction (TFR) or Notice to Airmen (NOTAM) information. Not all TFRs
and NOTAMS may be depicted.
Traffic Display
The display of traffic is intended as an aid to visual acquisition and must not be
used as the sole basis for rotorcraft maneuvering.
Surface Operations
SafeTaxi or Chartview functions shall not be used as the sole basis for
maneuvering in the airport environment. SafeTaxi and Chartview use is limited
to airport surface orientation to improve flight crew situational awareness during
airport operations.
MFD Video Display
Video images displayed on the MFD are intended for use as an aid to situational
awareness only. Rotorcraft maneuvering based solely on the MFD video display
is prohibited.
Glove Usage
No device may be used to cover fingers used to operate the TXi display unless
the Glove Qualification Procedure located in the Pilot’s Guide has been
successfully completed. The Glove Qualification Procedure must be
successfully completed for each combination of pilot, glove, and GDU
1060/700P/700L that is intended to be used.

Backup GPS
The Backup GPS is an emergency positional awareness function and must not
be used as a normal means of navigation.
Service Required
It is prohibited to initiate flight when a “Service Required” advisory is present
on the PFD or MFD.
ESI-500 Standby Indicator (if installed)
The pilot selectable units on the ESI-500 standby and TXi PFD are set to
matching units. This includes Barometric Correction and Altitude Type (meters
or feet).
Portable Electronic Devices
This STC does not relieve the operator from complying with operational
regulations regarding portable electronic devices.
The Flight Stream interface and data provided to a portable electronic device is
not approved to replace any rotorcraft display equipment, including navigation
or traffic/weather display equipment.
Database Updates
Database updates via MMC / SD card or Flight Stream wireless transfers must
be done while the rotorcraft is on the ground and stationary. In-flight database
transfers or updates are prohibited in flight unless part of the Database SYNC
function that occurs in the background to move databases from one LRU to
another.
Kinds of Operations
Equipment installed in a certified rotorcraft is approved for Day and Night /
VFR operations only when appropriately maintained.
One indication of altitude and magnetic heading, other than the G500H TXi, is
required. Operational regulations may require additional indication(s).

Abnormal Procedures
3.2.1 Heading Failure
Heading failure is indicated by removal of the digital magnetic heading display
on the HSI and a red
annunciation.
If GPS ground track is available, it will automatically be displayed in place of
heading. The 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.
NOTE
Without magnetic heading or GPS track, the CDI provides no
directional information. Only course deviation information is
presented, and the orientation of the CDI is based on the
selected course, regardless of rotorcraft heading. Course
deviation indications will behave like a traditional CDI. VOR
deviations will be relative to 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.

Display Brightness
Display brightness is controlled automatically based on input to a bezel mounted
photocell. The brightness level can be manually adjusted using controls in the
System → Backlight selection. Optionally, brightness can be controlled using
cockpit lighting dimmer switches.
System Power Sources
The G500H TXi system depends on electrical power to function. The Garmin
Display Unit (GDU) and Air Data Attitude and Heading Reference System
(ADAHRS) (or separate AHRS and ADC) are directly connected to the
rotorcraft’s main or essential bus and energized when the rotorcraft master
switch is turned on. Other systems, like the navigation equipment and weather
datalink are typically located on the avionics bus and may not be functional
when this bus is powered off.
The major components of the G500H TXi system are circuit breaker protected
with resettable type breakers available to the pilot. These breakers are labeled as
follows (appropriate boxes will be checked):

System Status
The G500H TXi system status can be viewed via the status page; this includes
the GDU serial number and system ID of the unit, the software version loaded
on the unit, and the AHRS and ADC software if the integral ADAHRS is
installed.
An External LRUs list displays information and status of various units that are
interfaced to the TXi system. This list only includes LRUs that can report status
information, which is typically limited to other Garmin LRUs. Software
versions, serial numbers, and LRU status is typically provided. A green
checkmark indicates normal online status, and a red X indicates offline or failed
status. Some LRUs, like the GDL 69, GSR 56, and GTX 345, provide a button
to see more detailed information about the status of that unit. These LRUspecific status pages provide additional controls, like the ability to register the
unit, as applicable.

Databases
The G500H TXi system utilizes databases to provide some system functions.
Database status information is available to the pilot at system startup on the
MFD splash screen and during normal operations on the MFD system status
page for units with an MFD, or PFD Menu for PFD only units. Controls are
provided for enabling database sync and chart streaming and for manually
initiating a database update. System time (as received from an interfaced GPS
navigator or the internal backup GPS) is used to determine if a database is
within its effective period. On the splash screen, databases are displayed in
amber if they are expired, not yet effective, or if the current date/time is
unknown. Databases are displayed in white if they are within their effective
date range. All database status information is depicted in white on the System
Status page.
The GDU utilizes two sets of databases – those which are active, and standby
databases which are databases whose valid period has not yet begun. Upon
reaching the effective date of a standby database the pilot is prompted to update
the database in use.
Internal database validation prevents incorrect data from being displayed.
Databases can be updated using an SD card, by Syncing with other compatible
units, or using database concierge through a FS510 and PED. Databases are
stored internally on the GDU.
The terrain and basemap databases are updated periodically and have no
expiration date.
The Garmin or Jeppesen navigation database contains data associated with
navigation including airports, navigation aids, airways, airspaces, and other data.
The obstacle database contains data for obstacles and wires that pose a potential
hazard to helicopters. Coverage of the obstacle database includes the United
States and Europe. Wire coverage is limited to the United States and some
portions of Canada and Mexico. This database is updated on a 56-day cycle.
CAUTION
Not all obstacles or wires are included in the databases.
The Garmin SafeTaxi database contains airport diagrams for selected airports.
This database is updated on a 56-day cycle.
The Garmin FliteCharts or Jeppesen ChartView electronic charts database
contains procedure charts for the coverage area purchased. An own-ship position
icon will be displayed on these charts when the rotorcraft icon on the chart page
is not X’d. This database is updated on a 28-day cycle. If not updated within 180
days of the expiration date, FliteCharts or 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
RFMS, G500H TXi P27 AML STC
190-02401-02 Rev. 2

directory information may be available from multiple sources and coverage
areas. This database is updated on a 56-day cycle.
The magnetic variation model contains data about variations in the earth’s
magnetic field based on location. This database is loaded using the GDU and is
stored on the AHRS. This database is included with the navigation database and
is updated on a five year cycle.
Crew Profiles
The crew profile function is provided for units which have an MFD to allow the
management of pilot controlled settings. If the rotorcraft is operated by multiple
pilots, each pilot can recall their individual settings for use. These profiles
include settings from all displays in the system.
Upon power up, the MFD splash screen provides the option for the pilot to
select a crew profile. If no selection is made the unit will default to the crew
profile used on the last power cycle. Profiles can be managed via the System –
Setup page. Only one profile may be selected as active at a time. New profiles
are created with the settings currently in use.
Display Backup Modes
Display backup modes are provided to replace the functionality of a failed PFD
by providing the same function on another display. Display backup capability is
enabled based on the configuration of the equipment installed in the rotorcraft.
Backup GPS
Each Garmin TXi GDU is equipped with a backup GPS receiver. When the
optional backup GPS antenna is connected, the TXi system will provide 2D GPS
position information from the backup GPS if all the certified GPS sources are
lost. There is no pilot action required to enable use of backup GPS data.
Backup GPS data is only used to provide non-safety critical functions after the
failure of all certified GPS position sources. Backup GPS data will only be
provided if a valid GPS position has been received from a certified GPS source
since becoming airborne and is subsequently lost.
Backup GPS data is utilized to provide the following functions: ownship
position on the moving map, GPS track display, waypoint bearing/distance
information, ground speed, and wind calculations. When backup GPS data is in
use, a yellow “BACKUP GPS” annunciation is displayed on all georeferenced
maps. Navigation using backup GPS is not provided. Overlays of traffic,
terrain, and obstacles on the moving map is disabled when backup GPS is in use.
Traffic information from TIS-A and TCAS sources is still available on the
traffic page. Other functions which are inhibited include bearing pointer on
waypoint info page, chart geo-referencing, Synthetic Vision, GPS altitude
displays, GPS navigation status field, and terrain page display.

Rotorcraft Audio Interface
The Pilot PFD is interfaced to the rotorcraft audio system to provide aural alerts
(altitude alerter, minimums, terrain).
GDU 700P MFD displays may be interfaced to audio system for terrain alerts or
touch clicks, but only if there is no Pilot PFD installed.
Advisory Notifications
An Advisory notification system is available on all installed GDUs. This system
notifies the pilot when a new advisory is available and displays a queue of active
advisories.
When a new advisory occurs, an “Advisory” button appears and flashes at the
bottom of each GDU.
Pressing the advisory button opens a popup window with a list of the active
advisories. Advisories are scrollable and are separated by a horizontal line
between entries.
Advisories are common to all GDUs, meaning that the same list of advisories is
displayed on all GDUs.
System Settings
The Setup page provides pilot controls for click volume, time format, and local
time offset. Controls are provided to set the nearest airport criteria so that
airports not usable by the rotorcraft type do not appear in waypoint searches. A
control is provided that allows the pilot to select which weather receiver is used
for the weather shortcut accessed by turning the outer dual concentric knob.
Crew profiles are managed from this page. Settings on this page are crossfilled
to all other GDUs in the system.
Units of Measure for temperature, barometric pressure, nav angle, altitude, fuel,
distance, and wind speed are pilot controllable via the System → Units page.
These units are propagated throughout the system with the exception of Air
Temperature Reference and Fuel Computer units which only affect the display
being used to make the selection.
The units and markings on the PFD are not user configurable. They match the
units as specified in the rotorcraft’s FAA approved Rotorcraft Flight Manual and
standby instruments.
System Data Logging
The TXi system incorporates a data logging feature that can record parameters
related to the rotorcraft’s primary flight instruments and rotorcraft configuration.
Recorded data is stored in internal memory and can be exported to an SD Card
by the pilot. Data logs can be sent via the Flight Stream 510 to a PED in the
cockpit.

Primary Flight Display
PFD functions are controlled by the dual concentric knob located adjacent to the
PFD and using touchscreen controls. The outer knob assigns the function of the
inner knob and is annunciated at the bottom of the display adjacent to the knob.
The PFD knobs control Selected Heading Bug, Course Pointer, Selected
Altitude Bug, Vertical Speed Bug, Airspeed Bug, and Barometric Correction. In
addition, the inner knob provides for numeric entry. The knob function defaults
to HDG if it is not rotated for a period of 10 seconds.
The PFD can also be controlled using the touchscreen controls. Touching any of
the buttons on the screen will display a context sensitive menu. The inner knob
may be used to directly change the displayed value or buttons within the menu
may be used to access additional control or utilize the touchscreen to enter data.
The PFD can optionally be controlled using a remotely mounted controller
which provides dedicated knobs and buttons for Selected Heading Bug, Course
Pointer, Selected Altitude Bug, Vertical Speed Bug, Airspeed Bug, and
Barometric Correction.
A Menu button on the PFD provides access to additional controls and settings.
7.13.1 Primary Flight Data
The PFD displays attitude, heading, airspeed, barometric altitude, and vertical
speed data. Airspeed and altitude displays include a six second trend indicator.
Pilot selectable bugs may be provided for airspeed, altitude, vertical speed, and
heading.
The G500H TXi requires at least one Garmin GPS/SBAS navigation unit to
ensure the integrity of the Attitude and Heading Reference System. The
ADAHRS or AHRS will continue to operate in a reversionary mode if the GPS
fails, and the attitude display on the PFD will still be presented.
When dual ADC or AHRS sensors are installed and configured, the pilot is
provided with AHRS/ADC source selection controls via the PFD Menu →
Sensors menu.
The default ADC or AHRS source on power up is ADC 1 and AHRS 1 for the
pilot side PFD and ADC 2 and AHRS 2 for the co-pilot side PFD.
Selection of ADC 2 or AHRS 2 as the sensor source will cause a “ON ADC 2”
or “ON AHRS 2”, respectively, to be displayed with black text on a white
background, to the right of the HSI.
When dual ADC or AHRS sensors are installed and configured, software
monitors provide detection of sensor miscompares. If a monitor detects a
difference between sources exceeding the allowable limit, a visual attitude,
altitude, or airspeed miscompare annunciation will be shown on the PFD.
RFMS, G500H TXi P27 AML STC
190-02401-02 Rev. 2
Page 32 of 43
Miscompares are annunciated using black text on a yellow background as
follows: airspeed miscompare is “IAS” shown below the airspeed pointer,
barometric altitude miscompare is “ALT” below the barometric altitude pointer,
and attitude miscompare is “ATTITUDE” on the attitude indicator. The PFD
inhibits the “IAS”, “ALT”, and “ATTITUDE” annunciations in dual TXi PFD
installations when both PFDs are displaying the same sensor source.
A no compare monitor is used to determine when data to the second ADC or
AHRS source is not able to be used for comparison. No compares are
annunciated using black text on a white background in the same location and
same text as miscompare annunciations.
7.13.2 Attitude
The attitude display is a blue over brown presentation and optionally can display
synthetic vision data (SVT).
Standard rate turn marks are provided on the roll scale for bank angles less than
30 degrees. A turn rate indicator is displayed across the top of the HSI compass
dial. Tick marks are shown for half-standard and standard rate turns.
If pitch exceeds 20° nose down or 30° nose up, or bank angle exceeds ±65°, the
attitude display will automatically declutter removing non-essential data to
facilitate recognition and recovery from extreme attitudes. Red chevrons which
indicate the direction to level pitch are displayed when pitch attitudes exceed
30° nose down or 50° nose up.
Slip/skid information is shown using a white trapezoid below the sky pointer.
7.13.3 Synthetic Vision Technology
SVT may optionally be provided to assist the pilot in maintaining situational
awareness with regard to the terrain, obstacles, and traffic surrounding the
rotorcraft.
SVT controls are provided via Menu → Terrain/SVT. Synthetic terrain, horizon
headings, and airport signs can be toggled on and off from this menu.
SVT provides additional information on the PFD:
•
Synthetic Terrain: an artificial, database derived, three dimensional
view of the terrain ahead of the rotorcraft within a field of view of
approximately 25 degrees left and 25 degrees right of the rotorcraft
heading.
•
Obstacles: obstacles such as towers, including buildings that are within
the depicted synthetic terrain field of view.
•
Powerlines: 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 rotorcraft. The FPM is displayed when synthetic
terrain is selected for display and groundspeed is greater than 30 knots.
RFMS, G500H TXi P27 AML STC
190-02401-02 Rev. 2
Page 33 of 43
•
Traffic: a display on the PFD indicating the position of other rotorcraft
detected by a traffic system interfaced to the G500H system.
•
Horizon Line: a white line indicating the true horizon is always
displayed on the SVT display.
•
Horizon Headings: 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.
The synthetic terrain display is intended to aid the pilot awareness of the terrain
and obstacles in front of the rotorcraft. 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 rotorcraft control in place of the primary flight instruments.
7.13.4 Airspeed
The airspeed tape on the left side of the PFD displays a red band to indicate the
power on maximum allowable airspeed (VNE) and either a red/white line or blue
line to indicate the power off VNE. These maximum allowable airspeed displays
can be configured to indicate the current appropriate maximum allowable
airspeed for the helicopter dynamically accounting for changes in altitude and
temperature. Dynamic display of power on VNE and power off VNE do not
account for additional limitations to VNE such as for doors off or external load.
Standby airspeed indications do not account for changes to V NE due to changes
in temperature and altitude. The pilot must refer to the Rotorcraft Flight Manual
(RFM)to determine the correct VNE for the current conditions and configuration.
Depending on configuration, a yellow arc may be displayed between zero knots
and the bottom or green arc to denote that airspeed indications are unreliable in
this range.
Airspeed will be configured to be displayed in units (knots, MPH, KMH)
matching the units used for limitations in the RFM and will match the standby
indicator units.
Airspeed reference bugs are provided on the airspeed tape and are pilot
configurable via Menu → Airspeeds.
True airspeed and groundspeed are displayed below the airspeed tape and are
always in knots.
RFMS, G500H TXi P27 AML STC
190-02401-02 Rev. 2
Page 34 of 43
7.13.5 Barometric Altitude and Vertical Speed
Barometric Altitude and Vertical Speed are displayed on the right side of the
display. Barometric correction can be set using dual rotary knobs or
touchscreen. Selected altitude and vertical speed bugs may be provided and
when set are synchronized across all PFDs. The selected altitude bug may be
removed by selecting a value of -1,000ft.
Barometric altitude is required for Vertical Navigation (VNAV) calculations on
interfaced GTN.
Barometric altitude (vertical speed) units are set during installation and will be
displayed in either feet (ft/sec) or meters (m/s). There is not pilot control for
altitude units.
Barometric correction units may be selected by the pilot.
The vertical speed indication an instantaneous type which uses acceleration data
from the AHRS to reduce lag in the display of vertical speed. In the event of an
AHRS failure the vertical speed indication will revert to a non-instantaneous
type and will have more lag.
7.13.6 Navigation
Navigation information is presented on the PFD through a combination of
horizontal situation indicator (HSI), a lateral deviation indicator (LDI) above the
heading display, vertical deviation indicator (VDI), and GPS navigation status
information. Optional bearing pointers and marker beacon annunciations may
be displayed.
Navigation information can be cycled through up to four independent sources by
pressing the “CDI” touchscreen button at the bottom center of the display. The
selected navigation source is shown on the left side of the HSI or LDI.
Automation of CDI source selection and course selection is provided in the
following situations:
•
•
•
Localizer CDI Switch Prompting – the CDI button on the PFD will
flash when established on the final approach course of a LOC-based
approach, if the CDI source is GPS. This serves as a reminder to
change the CDI source to LOC.
Localizer Course Auto-Slewing – the appropriate LOC course will be
automatically preset when a LOC-based approach is loaded in the
navigator and the CDI source is not already selected to LOC.
Missed Approach Point Auto-Switching from VLOC to GPS – When
the missed approach segment of an approach is begun (navigator
unsuspended after the missed approach point), the CDI source will
automatically switch from VOR/LOC back to GPS.
RFMS, G500H TXi P27 AML STC
190-02401-02 Rev. 2
Page 35 of 43
7.13.7 HSI
The course pointer and deviation indicator are shown as a single, solid line for
GPS 1 and VLOC 1, and as an outline with no fill for GPS 2 and VLOC 2. GPS
and VLOC sources are further differentiated with color.
The selected course is displayed above and to the right of the HSI. The selected
course is set via touchscreen keyboard entry or dual-concentric knob.
In addition, the HSI can display two simultaneous bearing pointers sourced from
GPS, VHF NAV.
The bearing pointer display and navigation source are pilot controlled under the
PFD Menu → HSI Setup → Bearing Pointers sub menu.
On the GDU 1060 and GDU 700P PFDs an enhanced HSI may be selected by
the pilot under the PFD Menu → HSI Options sub menu. The enhanced HSI
includes an integral moving map within the HSI depiction. HSI map data is a
subset of the data on the MFD map page. Traffic, terrain, obstacle, topographic,
and weather overlays are also available for the HSI map. Flight plan, runways,
terrain alerts, and TFRs are always displayed. Overlays are controlled on the
HSI Map Overlays menu.
7.13.8 Lateral Deviation Indicator (LDI)
A Lateral Deviation Indicator (LDI) is always displayed on the PFD above the
heading display. This LDI shows course deviation, navigation source, and
VLOC station identifier or GPS phase of flight. The LDI uses the same color
convention as the HSI .
The LDI incorporates automatic reverse sensing correction into the deviation
display. When the difference between the heading and the selected course is
greater than 107°, the LDI will enable reverse sensing correction. Reverse
sensing correction inverts the course deviation needle and to/from indicator so
that they correctly indicate the direction of the course and waypoint. The course
deviation needle will be deflected in the direction of the desired course, and the
to/from indicator will point in the direction of the waypoint (similar to how the
HSI depiction inverts with heading changes).
Message, waypoint, OBS, SUSP, phase of flight, LOI, and DR annunciations
from a GTN or GNS interfaced to the TXi are annunciated on the upper CDI.
7.13.9 Vertical Deviation Indication (VDI)
Vertical guidance is shown by a vertical deviation indicator (VDI) inboard of the
barometric altitude tape. The VDI displays either glideslope (GS) information
from an ILS source or enroute VNAV or glidepath (GP) information from for a
GPS approach.
RFMS, G500H TXi P27 AML STC
190-02401-02 Rev. 2
Page 36 of 43
7.13.10
Marker Beacon Display
The PFDs can show marker beacon annunciations from an interfaced marker
beacon receiver. The marker beacon annunciations are shown to the left of the
selected altitude.
7.13.11
Radar Altimeter Display
If interfaced to a radar altimeter the radar altitude will be displayed on the PFD
adjacent to the altitude tape. Additionally, when the radar altitude AGL value is
within the viewable range of the barometric altitude tape, a ground awareness
band is displayed.
The units of measure for radar altitude will be the same as those for barometric
altitude (ft or meters).
If the installed radar altimeter includes self-test capability the Test controls are
provided in the “Test” sub-menu under the PFD Menu. Refer to the Radar
Altimeter user documentation for information about values displayed during
Test.
NOTE
For KRA 405 Radar Altimeters the displayed Test value will
be between 25 and 50ft.
7.13.12
Altitude Minimums Display and Alerting
When configured at installation an aural alert will be provided when descending
through 100 ft (30 meters) radar altitude. There are no pilot controls for this
alert.
When enabled by the pilot, an altitude minimums bug will be displayed in cyan
on the barometric altitude tape. If a radar altimeter is installed, the pilot can
select between barometric or radar-altitude minimums.
Altitude minimums are accessed under the PFD Menu → Minimums sub menu
and can be set by touchscreen keypad or dual-concentric knob.
Both visual and aural altitude minimums alerts are provided. During a descent
to minimums, the minimums bug will change from cyan to white when the
rotorcraft descends to within 100 ft of minimums. An aural “Minimums,
Minimums” alert will be triggered when the rotorcraft’s altitude descends
through minimums and the minimums bug will change to yellow. As the
rotorcraft altitude climbs back above minimums, the minimums bug will change
to white 50 ft above minimums and cyan 150 ft above minimums. Alerting is
rearmed once the rotorcraft is 150 ft or more above the minimums altitude.
7.13.13
Outside Air Temperature/Density Altitude
The PFD provides a pilot configurable display of outside air temperature or
density altitude information below the airspeed tape. The pilot can choose to
show Static Air Temperature (SAT), Total Air Temperature (TAT), or
RFMS, G500H TXi P27 AML STC
190-02401-02 Rev. 2
Page 37 of 43
temperature delta from the International Standard Atmosphere (ISA). Density
Altitude can also be configured to be displayed instead of the temperature.
MFD Functions
The MFD functions are controlled using the dual concentric knob located
adjacent to the MFD or using touchscreen controls. The outer knob can be used
to select various MFD pages and is annunciated at the bottom of the display
adjacent to the knob. The inner knob can be used to control the display range.
Various MFD functions can be controlled using the touchscreen.
On all MFD pages, the nose of the ownship symbol represents the actual
location of your rotorcraft.
7.14.1 Map Page
A 2D moving map function is provided on the MFD. The appearance and
determination of data displayed on the moving map is controlled by pilot
selections made via a Menu button. The map menu provides on/off controls for
map overlays, a map detail selector, and a map setup button which accesses
additional map controls.
The map range can be altered using the touchscreen or rotary knob to allow for
display of data pertinent to the operation being conducted. The current zoom
scale or range of the map is continuously indicated by a range ring centered
around the ownship with a range indication at the 11 o’clock position on the
ring. In addition to zooming, a panning function is provided to allow the
position of the map to be centered on a location other than the ownship.
Panning mode is entered by dragging a single finger on the display. The map
orientation can be changed to North Up by pressing the North indicator arrow in
the top left corner.
If an active flight plan is present in the interfaced navigator, it will be depicted
on the map. Traffic, Terrain, Weather, Land, and Aviation data can be selected
for overlay on the map.
NOTE
The pilot may select map orientations of HDG UP, NORTH
UP, or TRACK UP. Use of TRACK UP is not preferred due to
the difficulty of interpreting display data in sideward and
rearward flight.
7.14.2 Traffic Display
The MFD can display traffic data from interfaced traffic systems. Sources of
traffic data include TIS-A, TAS/TCAS, and ADS-B traffic. The information
from these systems is displayed on and controlled using the MFD.
Traffic system operating controls and system status are provided on the
dedicated traffic page via touchscreen control in the lower left corner and/or the
RFMS, G500H TXi P27 AML STC
190-02401-02 Rev. 2
Page 38 of 43
Menu button, depending on the interfaced traffic system type. A display altitude
filter is provided in the lower right corner. Filtering of targets based on altitude
is accomplished by the display and affects the traffic page and map page. When
interfaced to a TIS traffic system, altitude filtering is not available.
The center of the traffic target icon serves as the reported location for the target
rotorcraft.
Additional functions are provided on the dedicated traffic page when an ADS-B
traffic system is interfaced including the depiction of motion vectors.
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 rotorcraft.
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 rotorcraft 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 rotorcraft.
Traffic can displayed on the moving map as an overlay. Additional filtering
based on traffic type (all, advisories, alerts) can be selected using the Menu
Traffic selection. For TIS-A traffic selection of the advisories and alerts will
result in display of alerted targets only.
Traffic page units are always in nautical miles and feet. If systems units for
altitude are selected to meters, then an annunciation is provided on the traffic
page indicating that traffic altitudes are depicted in feet and the traffic overlay
icon for the map includes a “FT” indication.
If a traffic alert occurs and the MFD is not selected to the dedicated traffic page,
then a traffic “popup window” is provided which depicts the traffic and
provides controls to either go to the dedicated traffic page or close the popup
window. On a GDU 1060, if a traffic alert occurs and display is showing a full
screen PFD, then a button is provided which will return to split screen mode and
display the dedicated traffic page. On systems with a PFD installed, a yellow
TRAFFIC annunciator is provided adjacent to the HSI.
CAUTION:
Due to limitations of the TIS-A traffic system resultant from it
being a track based system the displayed bearing of target
aircraft is not reliable when in hovering, rearward, or sideward
flight.

Terrain Awareness and Alerting
The following terrain awareness and alerting functions may be provided by the
TXi system: HTerrain Proximity or HTerrain FLTA. If the TXi system is
interfaced to a GNS or GTN navigator equipped with HTAWS, then the TXi
will display HTAWS parameters provided by the GNS or GTN. The Terrain or
TAWS function being provided by the TXi system is indicated by a text box in
the lower left corner of the Terrain Page.
Terrain Proximity function is a 2D depiction of terrain, obstacle, and powerlines
with no alerting. A dedicated terrain page is provided on the MFD on which the
relative height of terrain, obstacles, and powerlines are depicted using color to
convey the height of the obstruction relative to rotorcraft altitude based on
database data. An obstacle and/or wire overlay icon will be shown near the
bottom of the display when the obstacle or wire depiction is being provided as
determined by the zoom scale. The Terrain Proximity function is present on the
system regardless of other higher level terrain functions that may be selected.
Relative terrain elevation is depicted using a five color scale in which terrain
that is at or above the helicopter’s current altitude is depicted in orange and red
while terrain within 250 feet of the helicopter’s current altitude is shown in
yellow.
Obstacles (including wire segments) on the dedicated terrain page or main map
are depicted in the following manner:
• Lines and obstacles more than 500 ft below the helicopter are not
depicted.
• Lines and obstacles between 500 ft and 250 ft below the helicopter are
depicted as white.
• Lines and obstacles between 250 ft below and at the same GPS altitude
of the helicopter are depicted as amber.
• Lines and obstacles at the same altitude or above the helicopter are
depicted as red.
CAUTION
The Obstacle Database contains only KNOWN obstacles and
wires, and does not contain ALL existing obstacles or wires that
may pose a threat to the helicopter.
If SVT is enabled in the TXi system, then the HTerrain - FLTA function is
provided. Forward Looking Terrain Alerts and Reduced Terrain Clearance
Alerts are provided for terrain, obstacles, and wires.
If the TXi is interfaced to a GNS or GTN with HTAWS enabled, then TAWS
alerts are only displayed from the GPS/TAWS navigator interfaced as GPS 1
and are displayed regardless of the CDI 1-2 setting.
Visual indications are provided for terrain, obstacle, and wire alerts as follows:

•
For all TXi configurations which provide alerts and all configurations
where the TXi is interfaced to GNS or GTN with HTAWS enabled:
o An annunciator located on the PFD adjacent to the HSI
provides text annunciations of system status, self-test, and
alert conditions using yellow, red, or white as appropriate to
the condition.
•
For all TXi configurations which provide alerts and configurations
where the TXi is interfaced to a GTN with HTAWS enabled:
o If a terrain alert occurs and the MFD is not selected to the
dedicated terrain page, then a terrain “popup window” is
provided, which depicts the obstruction generating the alert
with controls provided to either go to the dedicated terrain
page or close the popup window. On a GDU 1060, if a terrain
alert occurs and the display is showing a full screen PFD, a
button is provided which will return to split screen mode and
display the dedicated terrain page.
o The terrain page and map page will depict the area or
obstruction causing the alert as an area of color corresponding
to the alert severity and encircling the obstruction.
o If Synthetic Vision depiction is turned on, an area
corresponding to the alert area on the map/terrain page is
shaded in the corresponding color for terrain alerts. Obstacle
and powerline alerts will cause the relevant obstacle to be
depicted in the alert color in SVT.
Controls are provided for terrain, obstacle, and wire alerts as follows:
•
For all TXi configurations in which the TXi system provides alerts:
o Controls are provided in the menu on the Terrain Page. An
“RP Mode” button inhibits caution alerts and reduces the
times and distances for terrain, obstacle, and powerline
warnings when pressed. A “Terrain Inhibit” button inhibits
terrain, obstacle, and powerline alerts when pressed.
Annunciations are provided on the PFD and Terrain Page to
indicate that RP Mode is selected or alerts are inhibited. A
“Terrain Test” button initiates a self-test sequence which
results in aural and visual self-test annunciations.

7.15.1 Charts
The MFD provides depiction of aeronautical charts on a dedicated charts page as
well as the map page. Charts are geo-referenced on both the map and charts
pages. The map page will always depict the chart that is currently selected on
the charts page; this chart is overlaid on top of the terrain, TOPO, and Basemap
layers but below the traffic and ownship layers. The overlaid chart is oriented
appropriately for the current orientation of the map considering the selected map
orientation and position/direction of the ownship. The charts page will include a
depiction of the ownship, colored magenta, if the selected chart supports georeferencing and the ownship is located within a geo-referenced portion of the
selected chart. If geo-referencing is not available on the charts page an icon is
presented that indicates the ownship is not being depicted.
7.15.2 Flight Plan Page
The MFD includes a Flight Plan page which displays the active flight plan from
the interfaced GPS navigator. The flight plan page is only a display of the active
flight plan from the navigator (flight plans in the navigator catalog cannot be
displayed). The active flight plan cannot be edited using the MFD. Flight plan
waypoints for which addition information is available appear as buttons.
Touching a button will jump to the Waypoint Info page for that waypoint.
On a GDU 1060, the active flight plan is shown for the GPS source that
corresponds to the PFD CDI selection (e.g. GPS 1 when the CDI source is GPS
1 or VOR/LOC 1, GPS 2 when the CDI source is GPS 2 or VOR/LOC 2). This
is the same GPS source shown on the PFD NAV Status field..
On a GDU 700P MFD, the active flight plan for GPS 1 is always displayed. The
GPS 2 flight plan is never shown on a GDU 700P MFD.
7.15.3 Weather Data
The MFD can display weather data from interfaced datalink systems. Sources of
weather data include the Garmin “GDL 69(A)” and “GDL 69(A) SXM” Sirius
XM receivers, Garmin GSR 56 Iridium Transceiver, and Garmin ADS-B
transceivers. If one of these optional weather datalink receivers is installed, the
pilot will be able to access graphical and text weather products using the MFD.
Datalink weather products use color and/or timestamps to indicate the recency
with which the data was received.
Selected weather products from each receiver can be overlaid on the map page
as well as the enhanced HSI map while all received products can be displayed
on the dedicated weather pages. The products available on the map page and
HSI are different for each weather receiver. The map page and HSI provide
controls to select the desired weather receiver; only one weather receiver can be
selected at a time.
Text and graphical datalink weather associated with a facility can only be
viewed when a database which includes that facility is installed.

7.15.4 Video Display
The MFD can display images from up to 2 video inputs. The TXi does not
provide a means to control the video source; however the digital images from
some video sources can be adjusted using the MFD.
7.15.5 Waypoint Information
The MFD provides pages that display information about the different waypoint
types. These pages can be accessed by touching one of the supported waypoint
types on the map and then pressing the provided Waypoint Info button, or by
navigating to the Waypoint Info page group from the home page.
Flight Stream 510 (Optional)
The Flight Stream product line uses a wireless transceiver to provide data to and
from a TXi to personal electronic devices (PEDs). The Flight Stream 510 is
mounted in the TXi display SD card slot and includes a Bluetooth and Wi-Fi
transceiver.
Data such as traffic, datalink weather, entertainment audio information, and
attitude information is sent from the Flight Stream to the PED. The PED is
capable of sending databases to the Flight Stream which will then be available
on the TXi and other interfaced equipment. Limitations regarding database
operations are found in Section 2.21.
Garmin provides a list of tested and compatible devices that can be used with the
Flight Stream. Connection to the Flight Stream may be possible with devices
other than those on the supported device list, but Bluetooth® and/or Wi-Fi
stability and wireless data integrity cannot be guaranteed.
For details about the Garmin supported devices and apps for use with the Flight
Stream product line, please visit: http://garmin.com/connext/supported_devices
Database Provided Altitudes
When the TXi displays altitude data for waypoints included in IFR procedures,
the altitudes provided are those shown on the procedure chart for “Turbojet” or
“Jet” aircraft. If altitudes for other aircraft are required, the crew must manually
edit the waypoint altitude on the GTN navigator.
