Warnings, Cautions & Notes
WARNING: Navigation and terrain separation must NOT be predicated upon
the use of the terrain function. The aera 795/796 Terrain Proximity feature
is NOT intended to be used as a primary reference for terrain avoidance
and does not relieve the pilot from the responsibility of being aware of
surroundings during flight. The Terrain Proximity feature is only to be used
as an aid for terrain avoidance and is not certified for use in applications
requiring a certified terrain awareness system. Terrain data is obtained from
third party sources. Garmin is not able to independently verify the accuracy
of the terrain data.
WARNING: The displayed minimum safe altitudes (MSAs) are only advisory
in nature and should not be relied upon as the sole source of obstacle and
terrain avoidance information. Always refer to current aeronautical charts
for appropriate minimum clearance altitudes.
WARNING: The altitude calculated by aera 795/796 GPS receivers is geometric
height above Mean Sea Level and could vary significantly from the altitude
displayed by pressure altimeters. Always use pressure altitude displayed by
the aircraft altimeter when determining or selecting aircraft altitude.
WARNING: Do not use outdated database information. Databases used in
the aera 795/796 system must be updated regularly in order to ensure that
the information remains current. Pilots using any outdated database do so
entirely at their own risk.
WARNING: Do not use data link weather information for maneuvering in,
near, or around areas of hazardous weather. Information contained with in
data link weather products may not accurately depict current weather conditions.
WARNING: Do not use the indicated data link 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 data link transmission, the weather information shown by the data
link weather product may be significantly older than the indicated weather
product age.

190-01194-00 Rev. C
Warnings, Cautions & Notes
WARNING: To reduce the risk of unsafe operation, carefully review and
understand all aspects of the aera 795/796 Pilot’s Guide documentation and
the Pilot’s Operating Handbook of the aircraft. Thoroughly practice basic
operation prior to actual use. During flight operations, carefully compare
indications from the aera 795/796 to all available navigation sources, including
the information from other NAVAIDs, visual sightings, charts, etc. For safety
purposes, always resolve any discrepancies before continuing navigation.
WARNING: For safety reasons, aera 795/796 operational procedures must
be learned on the ground.
WARNING: When installing the aera™ 795/796, place the unit so it does not
obstruct the field of view or interfere with operating controls.
WARNING: The indicators represented on the Panel are based on GPS-derived
data and may differ from the instruments in the aircraft.
WARNING: The United States government operates the Global Positioning
System and is solely responsible for its accuracy and maintenance. The GPS
system is subject to changes which could affect the accuracy and performance
of all GPS equipment. Portions of the Garmin aera 795/796 utilize GPS as a
precision electronic NAVigation AID (NAVAID). Therefore, as with all NAVAIDs,
information presented by the aera 795/796 can be misused or misinterpreted
and, therefore, become unsafe.
WARNING: The data contained in the terrain and obstacle databases comes
from government agencies. Garmin accurately processes and cross-validates
the data, but cannot guarantee the accuracy and completeness of the data.
WARNING: Do not use basemap (land and water data) information for
primary navigation. Basemap data is intended only to supplement other
approved navigation data sources and should be considered as an aid to
enhance situational awareness.

Warnings, Cautions & Notes
BATTERY WARNINGS:
If these guidelines are not followed, the internal lithium-ion battery may
experience a shortened life span or may present a risk of damage to the
GPS device, fire, chemical burn, electrolyte leak, and/or injury.
• Do not leave the device exposed to a heat source or in a hightemperature location. To prevent damage, remove the device from the
aircraft or store it out of direct sunlight.
• Do not puncture or incinerate the device or battery.
• When storing the device for an extended time, store within the
following temperature range: from 32˚ to 77˚F (from 0˚ to 25˚C)
• Do not operate the device outside of the following temperature range:
from -4˚ to 131˚F (from -20˚ to 55˚C).
• Contact your local waste disposal department to dispose of the
device/battery in accordance with applicable local laws and
regulations.
Additional User-Replaceable Battery Warnings:
• Do not use a sharp object to remove the battery.
• Keep the battery away from children.
• Do not disassemble, puncture, or damage the battery.
• Only replace the battery with the correct replacement battery. Using
another battery presents a risk of fire or explosion. To purchase a
replacement battery, see your Garmin dealer or the Garmin Web site.
WARNING: Do not rely solely upon the display of traffic information for collision
avoidance maneuvering. The traffic display does not provide collision avoidance
resolution advisories and does not, under any circumstances or conditions, relieve
the pilot’s responsibility to see and avoid other aircraft.
WARNING: Do not rely solely upon the display of traffic information to accurately
depict all of the traffic within range of the aircraft. Due to lack of equipment, poor
signal reception, and/or inaccurate information from aircraft or ground stations,
traffic may be present that is not represented on the display.
CAUTION: Avoid using any chemical or abrasive cleaners on the touchscreen
and/or plastic casing. Clean the touchscreen with a soft, clean, lint-free cloth.
Use water, isopropyl alcohol, or eyeglass cleaner, if needed.

Warnings, Cautions & Notes
CAUTION: The Garmin aera 795/796 does not contain any user-serviceable
parts. Repairs should only be made by an authorized Garmin service center.
Unauthorized repairs or modifications could void both the warranty and the
pilot’s authority to operate this device under FAA/FCC regulations.
NOTE: The Garmin aera 795/796 has a very high degree of functional integrity.
However, the pilot must recognize that providing monitoring and/or selftest capability for all conceivable system failures is not practical. Although
unlikely, it may be possible for erroneous operation to occur without a fault
indication shown by the aera 795/796. It is thus the responsibility of the pilot
to detect such an occurrence by means of cross-checking with all redundant
or correlated information available in the cockpit.
NOTE: All visual depictions contained within this document, including screen
images of the aera 795/796 panel and displays, are subject to change and
may not reflect the most current aera 795/796 system and aviation databases.
Depictions of equipment may differ slightly from the actual equipment.
NOTE: This product, its packaging, and its components contain chemicals
known to the State of California to cause cancer, birth defects, or reproductive
harm. This notice is being provided in accordance with California’s Proposition
65. If you have any questions or would like additional information, please
refer to our web site at www.garmin.com/prop65.
NOTE: Use of polarized eyewear may cause the display to appear dim or
blank.
NOTE: Temporary Flight Restriction (TFR) data is provided by the FAA and
may not be updated outside of normal business hours. Confirm data currency
through alternate sources and contact your local FSS for interpretation of TFR
data.

During initialization, current database information is displayed. Database information
includes valid operating dates, cycle number, and database type. When this information
has been reviewed for currency (to ensure that no databases have expired), the pilot
is prompted to continue.
GPS Navigation
The first time the unit is turned on, the receiver must collect satellite data and
establish its present location. To ensure proper initialization, the aera 795/796 is
shipped from the factory in AutoLocate mode, which allows the receiver to “find itself”
anywhere in the world.
Overview
The power button can be used to quickly set the backlight intensity. A momentary
press of the power button (after the unit is powered on) will display a window showing
the current backlight setting. From this window the backlight setting can be adjusted
with the on screen controls, or a second momentary press of the POWER Button
changes the backlight level to full bright (10).

SECTION 2 GPS NAVIGATION
Overview
2.1 INTRODUCTION
Flight Planning
An aircraft icon is placed on the Navigation Map at the location corresponding
to the calculated present position. The aircraft position and the flight plan legs are
accurately based on GPS calculations. The basemap upon which these are placed is
from a source with less resolution, therefore the relative position of the aircraft to map
features is not exact. The leg of the active flight plan currently being flown is shown as
a magenta line on the navigation map. The other legs are shown in white.
GPS Navigation
The Navigation Map displays aviation data (e.g., airports, VORs, airways, airspaces),
geographic data (e.g., cities, lakes, highways, borders), and topographic data (map
shading indicating elevation). The Navigation Map can be oriented three different
ways: North Up (NORTH UP), Track Up (TRK UP) or Desired Track Up (DTK UP).

HSI
Overview
The HSI/Panel shows GPS-derived data in a graphical format. Keep in mind the
differences between the GPS-derived panel and mechanical instruments, as mechanical
panel instruments use sensors that provide information different from that derived
using GPS.
Overview
GPS Navigation
The course deviation scale appears on the lower right corner of the HSI. There
are four CDI Scale settings ('Automatic', '0.25 nm', '1.25 nm', and '5.00 nm'. Three
factors are used to determine the distance from the center of the CDI to full left or right
limits when the CDI Scale is set to 'Automatic':
•CDI scale = 0.25 - on an approach leg or within 2 nm of the FAF or MAP.
GPS Navigation
•CDI scale = 1.25 - within 30 nm of any airport in the active route.
•CDI scale = 5.0 - if the previous two conditions do not exist.

The “Approaching VNAV Profile” message appears one minute prior to the initial
descent point. The descent angle locks to prevent changes in speed from altering the
profile. The VNAV feature does not take into account any changes in groundspeed that
occur during the transition from level flight to descent or climb.
At 500 ft above the target altitude, the “Approaching Target Altitude” message
appears, the ‘Estimated Time To VNAV’ goes blank, and the VNAV indicator disappears
from the HSI.
CAUTION: The aera 795/796 is a VFR navigation tool and should not be used
to perform instrument approaches.
CAUTION: VNAV is only a VFR navigation aid and is not intended for
instrument approaches.

AIRWAYS
Low Altitude Airways (or Victor Airways) primarily serve smaller piston-engine,
propeller-driven airplanes on shorter routes and at lower altitudes. Airways are eight
nautical miles wide and start 1,200 feet above ground level (AGL) and extend up
to but not including 18,000 feet mean sea level (MSL). Low Altitude Airways are
designated with a “V” before the airway number (hence the name “Victor Airways”)
since they run primarily between VORs.
High Altitude Airways (or Jet Routes) primarily serve airliners, jets, turboprops, and
turbocharged piston aircraft operating above 18,000 feet MSL. Jet Routes start at
18,000 feet MSL and extend upward to 45,000 feet MSL (altitudes above 18,000 feet

Low Altitude Airways are drawn in gray. High Altitude Airways are drawn in green.
When both types of airways are displayed, high altitude airways are drawn on top of
Low Altitude Airways.
Waypoints are predetermined geographical positions (internal database) or pilotentered positions, and are used for all phases of flight planning and navigation.
Appendices
The waypoint function allows the pilot to review airport/runway information,
frequencies, Airport Directory information (if available), weather information (if available) and Terminal Procedure Charts, by touching the desired tab (Info, Freq, WX,

SECTION 3 FLIGHT PLANNING
3.1 INTRODUCTION
Hazard Avoidance
Additional Features
Whenever an approach is loaded into the active flight plan it replaces the destination
airport with a sequence of waypoints for the selected approach. The airport must have
a published instrument approach and only the final course segment (usually from final
approach fix to missed approach point) of the published approach is available in the
aera 795/796.
Flight Planning
Up to 50 flight plans with up to 300 waypoints each can be created and stored in
memory. One flight plan can be activated at a time and becomes the active flight plan.
The active flight plan is erased when the destination is reached and the system is turned
off. When storing flight plans with an approach, the aera 795/796 uses the waypoint
information from the current database to define the waypoints. If the database is
changed or updated, the aera 795/796 automatically updates the information if the
procedure has not been modified. If an approach is no longer available, the procedure
is deleted from the affected stored flight plan(s), and an alert is displayed.
GPS Navigation
Flight planning on the aera 795/796 consists of building a flight plan by entering
waypoints one at a time and inserting approaches as needed.

NEXRAD (NEXt-generation RADar), is a network of multiple high-resolution Doppler
radar sites 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. In addition to a wide array of services, the NEXRAD network provides important
information about severe weather and air traffic safety.
Appendices
NEXRAD
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 or any radar
data to maneuver in or near areas of hazardous weather. Rather, use it in an earlywarning capacity of pre-departure and enroute evaluation.
Composite data from all the NEXRAD radar sites in the United States is shown. This
data is composed of the maximum reflectivity from the individual radar sweeps. The
display of the information is color-coded to indicate the weather severity level.
The display of radar coverage is always active when NEXRAD is selected. Areas
where NEXRAD radar coverage is not currently available or is not being collected are
indicated in grayish-purple. Radar capability exists in these areas, but it is not active
or is off-line.
NEXRAD Abnormalities
There are possible abnormalities regarding displayed NEXRAD images. Some, but
not all, of those include:
•Ground clutter
•Strobes and spurious radar data
Additional Features
Hazard Avoidance
Flight Planning
GPS Navigation
Overview
Hazard Avoidance
•Sun strobes, when the radar antenna points directly at the sun
•Military aircraft deploy metallic dust (chaff) which can cause alterations in radar

NEXRAD Limitations
Certain limitations exist regarding the NEXRAD radar displays. Some, but not all, are
listed for the user’s awareness:
•NEXRAD base reflectivity does not provide sufficient information to determine
cloud layers or precipitation characteristics (hail vs. rain). For example, it is not
possible to distinguish between wet snow, wet hail, and rain.

Hazard Avoidance
Overview
•NEXRAD base reflectivity is sampled at the minimum antenna elevation angle. An
individual NEXRAD site cannot depict high altitude storms at close ranges, and
has no information about storms directly over the site.
•Radar coverage only extends to 55°N.
NEXRAD Intensity
Hazard Avoidance
RADAR Legend
Flight Planning
Colors are used to identify the different NEXRAD echo intensities (reflectivity)
measured in dBZ (decibels of Z). “Reflectivity” (designated by the letter Z) is the
amount of transmitted power returned to the radar receiver. The dBZ values increase
as returned signal strength increases. Precipitation intensity is displayed using colors
corresponding to the dBZ values.
GPS Navigation
•Any precipitation displayed between 52°N and 55°N is unknown.

Winds Aloft are displayed using wind barbs or a wind streamline depending on
the selected range. The wind barbs indicate wind speed and direction. The wind
streamline indicates wind direction with arrows.
The wind barbs always point in the direction that the wind is coming from. The wind
speed is depicted using flags at the end of the wind barb. A short wind flag is 5 knots,
a long wind flag is 10 knots, and a triangle flag is 50 knots.

METARS AND TAFS
NOTE: METAR information is only displayed within the installed aviation
database service area.
METAR (METeorological Aerodrome Report) is an international code used for
reporting weather observations. METARs are updated hourly or as needed. METARs
typically contain information about the temperature, dewpoint, wind, precipitation,
cloud cover, cloud heights, visibility, and barometric pressure. They can also contain
information on precipitation amounts, lightning, and other critical data. If METAR data
is available for an airport, a color-coded flag is shown next to the airport.
TAF (Terminal Area Forecast) is the standard format for 24-hour weather forecasts.
TAFs may contain some of the same code as METAR data. It typically forecasts
significant weather changes, temporary changes, probable changes, and expected
changes in weather conditions.
An abbreviated version can be viewed by selecting the METAR flag with the map
pointer. Touching the Map Feature Button will display additional information. METAR
and TAF data can be displayed as raw or decoded text.

When a FIS-B weather product is active on a map, the age of the data is displayed
on the screen in the lower left corner. The age of the product is based on the time
difference between when the data was assembled on the ground and the current GPS
time. Weather products are broadcast at specific intervals (see broadcast interval in
the table below).
Index
Appendices
FIS-B weather broadcasts are updated regularly and may take approximately
ten minutes to transmit all available weather data. Therefore, weather data is not
immediately available. No pilot action is required to receive FIS-B weather information.
Weather product status can be viewed on the dedicated Weather Page,or the Data Link
Page from the Tools menu.

FIS-B WEATHER PRODUCTS
If, for any reason, a weather product is not refreshed within the Expiration Time
intervals (see table), the data is considered expired and is removed from the display.
This ensures that only data that is consistent with FIS-B broadcast data is displayed.
If more than half of the expiration time has elapsed, the color of the product age
displayed changes to yellow. The system displays dashes instead of a product age
when a product has expired. If a weather product is not available or has not been
received, the system displays ‘N/A’ instead of a product age.
The table below shows the FIS-B weather expiration time and the broadcast interval.

NEXRAD (NEXt-generation RADar), is a network of multiple high-resolution Doppler
radar sites 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. In addition to a wide array of services, the NEXRAD network provides important
information about severe weather and air traffic safety.

Overview
Hazard Avoidance
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 or any radar
data to maneuver in or near areas of hazardous weather. Rather, use it in an earlywarning capacity of pre-departure and enroute evaluation.
Composite data from all the NEXRAD radar sites in the United States is shown. This
data is composed of the maximum reflectivity from the individual radar sweeps. The
display of the information is color-coded to indicate the weather severity level.
The display of radar coverage is always active when NEXRAD is selected. Areas
where NEXRAD radar coverage is not currently available or is not being collected are
indicated in grayish-purple. Radar capability exists in these areas, but it is not active
or is off-line.
NEXRAD Abnormalities
There are possible abnormalities regarding displayed NEXRAD images. Some, but
not all, of those include:
•Ground clutter
•Strobes and spurious radar data
•Sun strobes, when the radar antenna points directly at the sun
•Military aircraft deploy metallic dust (chaff) which can cause alterations in radar
scans
Index
Appendices
•Interference from buildings or mountains, which may cause shadows
•Poor reception from Ground Based Transceivers (GBTs) can cause portions of the
received radar imagery to not be displayed
NEXRAD Limitations
Certain limitations exist regarding the NEXRAD radar displays. Some, but not all, are
listed for the user’s awareness:

NEXRAD Intensity
Flight Planning
Colors are used to identify the different NEXRAD echo intensities (reflectivity)
measured in dBZ (decibels of Z). “Reflectivity” (designated by the letter Z) is the
amount of transmitted power returned to the radar receiver. The dBZ values increase
as returned signal strength increases. Precipitation intensity is displayed using colors
corresponding to the dBZ values.
GPS Navigation
•NEXRAD base reflectivity is sampled at the minimum antenna elevation angle. An
individual NEXRAD site cannot depict high altitude storms at close ranges, and
has no information about storms directly over the site.
Overview
•NEXRAD base reflectivity does not provide sufficient information to determine
cloud layers or precipitation characteristics (hail vs. rain). For example, it is not
possible to distinguish between wet snow, wet hail, and rain.

METARS AND TAFS
NOTE: METAR information is only displayed within the installed aviation
database service area.
METAR (METeorological Aerodrome Report) is an international code used for
reporting weather observations. METARs are updated hourly or as needed. METARs
typically contain information about the temperature, dewpoint, wind, precipitation,
cloud cover, cloud heights, visibility, and barometric pressure. They can also contain
information on precipitation amounts, lightning, and other critical data. If METAR data
is available for an airport, a color-coded flag is shown next to the airport.
TAF (Terminal Area Forecast) is the standard format for 24-hour weather forecasts.
TAFs may contain some of the same code as METAR data. It typically forecasts
significant weather changes, temporary changes, probable changes, and expected
changes in weather conditions.
An abbreviated version can be viewed by selecting the METAR flag with the map
pointer. Touching the Map Feature Button will display additional information. METAR
and TAF data can be displayed as raw or decoded text.

4.2 TERRAIN
NOTE: Terrain depicted in the Profile View is always “ahead” of the aircraft,
and will change as ground track changes.
The Terrain function displays altitudes of terrain and obstructions relative to
the aircraft position and altitude with reference to a database that may contain
inaccuracies. Terrain and obstructions are shown only if they are in the database.
Terrain and obstacle information should be used as an aid to situational awareness.
They should never be used to navigate or maneuver around terrain.
Note that all obstructions may not be available in the terrain and obstacle database.
No terrain and obstacle information is shown without a valid 3-D GPS position.
Appendices
The aera 795/796 GPS receiver provides the horizontal position and altitude of the
aircraft. Aircraft GPS altitude is derived from satellite position. GPS altitude is then
converted to a mean sea level (MSL)-based altitude (GPS-MSL altitude) and is used to
determine terrain and obstacle proximity. GPS-MSL altitude accuracy is affected by
satellite geometry, but is not subject to variations in pressure and temperature that
normally affect pressure altitude sensors. GPS-MSL altitude does not require local
altimeter settings to determine MSL altitude. It is a widely-used MSL altitude source.
Terrain and obstacle databases are referenced to MSL. Using the GPS position
and altitude, the Terrain feature portrays a 2-D picture of the surrounding terrain and
obstacles relative to the position and altitude of the aircraft. GPS position and GPSMSL altitude are used to calculate and predict the aircraft’s flight path in relation to the
surrounding terrain and obstacles. In this way, the pilot can view predicted dangerous
terrain and obstacle conditions.

the aera 795/796 is configured with both a Mode S transponder capable of receiving
TIS-A traffic and a GDL 39 capable of receiving ADS-B/TIS-B traffic the aera 795/796
will automatically switch between traffic sources. The following conditions describe
the traffic display logic.
•If the GTX is not receiving TIS-A traffic data, GDL 39 ADS-B traffic will be displayed.
•If the GDL 39 is receiving both air-to-air ADS-B traffic data and ground uplink
TIS-B traffic, then the GDL 39 ADS-B traffic will be displayed.
•If the GTX is receiving TIS-A traffic, and the GDL 39 is not receiving ground uplink
TIS-B traffic, then GTX TIS-A traffic will be displayed.

only reduces the “nuisance” alerting due to proximate aircraft. For example, when the
first Traffic Advisories appear on the TIS-A display, the user is alerted audibly. So long
as a single aircraft remains on the TIS-A display, no further audio alert is generated. If
a second (or more) aircraft appears on the screen, a new audio alert is sounded.

DATA LINK TRAFFIC (GDL 39)
The GDL 39 is a Bluetooth® enabled receive-only data link radio with on-board
GPS, 978 MHz (Universal Access Transceiver frequency band), and 1090 MHz Extended
Squitter (1090 ES) receivers. It is designed to receive, process, and output traffic (ADS-B
air-to-air, and TIS-B traffic information), and weather (Flight Information ServiceBroadcast (FIS-B)) information to the aera 795/796 through a power/data cable.
ADS-B (Automatic Dependent Surveillance-Broadcast) is a surveillance technology
deployed across the United States as the cornerstone of the FAA’s Next Generation Air
Transportation System (NextGen). ADS-B enables improved surveillance services, both
air-to-air and air-to-ground, especially in areas where radar is ineffective due to terrain
or where it is impractical or cost prohibitive. Initial applications of air-to-air ADS-B are
for “advisory” use only, enhancing a pilot’s visual acquisition of other nearby ADS-B
equipped aircraft either when airborne or on the airport surface.

ADS-B System
For the purpose of distinguishing between levels of ADS-B service, there are three
classifications of aircraft or system capability; ADS-B In, ADS-B Out, and ADS-B
participating. ADS-B In refers to the capability to receive ADS-B information. ADS-B
126
Garmin aera 795/796 Pilot’s Guide
190-01194-00 Rev. C
Hazard Avoidance
Out refers to the capability to transmit ADS-B information. ADS-B participating refers
to the capability to both send and receive ADS-B information. Aircraft lacking either
ADS-In, ADS-B Out, or both ADS-B capabilities may also be referred to as ADS-B nonparticipating aircraft.
Overview
Currently, rule-compliant ADS-B Out capability in the United States requires a
TSO’ed SBAS-enabled GPS, such as a Garmin GPS 400W or similar, and one of two
possible data links: 1090 ES transponder or a 978 MHz UAT. Either data link system
is capable of transmitting the aircraft’s position, velocity, identification, and other
information every second to compatible aircraft and ground stations called Ground
Based Transceivers (GBTs).

TIS-B traffic information includes non-participating aircraft detected by ATC
surveillance radar. As TIS-B data is derived from ATC surveillance radar data, TIS-B
traffic position updates typically occur every three to thirteen seconds. Therefore,
Additional Features
FIS-B service is provided continuously, but ADS-R including TIS-B will only be
broadcast by a GBT when an ADS-B participating aircraft is within the GBT’s defined
service volume. In this case, a GBT will only rebroadcast TIS-B information relative
to the ADS-B participating aircraft. Only traffic that is within 15 nm lateral
and 3,500’ vertical of the ADS-B participating aircraft is provided in the
broadcast. Non-participating traffic aircraft located farther than 15 nm laterally and
3,500’ vertically from the participating aircraft is are excluded from the information
transmitted by the GBT.
Hazard Avoidance
Thus, the GDL 39 receives traffic information directly from any ADS-B Out aircraft
within range as well as the rebroadcast of ADS-B information from any nearby GBT.
This rebroadcast is called Automatic Dependent Surveillance-Rebroadcast (ADS-R) and
is automatically triggered by the detection of an ADS-B participating aircraft within the
service volume of the GBT. As a 978 MHz (UAT frequency) receiver, the GDL 39 can
receive both the Traffic Information Service-Broadcast (TIS-B) and Flight Information
Service-Broadcast (FIS-B) provided in conjunction with ADS-R services when in range
of a GBT.
Flight Planning
Because 1090 ES transponders and UATs operate on different frequencies, aircraft
not similarly equipped cannot transmit/receive data link information directly to/from
each other. Instead, operation within range of a GBT is required to receive data link
information on both frequencies. The GDL 39 is unique in its ADS-B In capability since
it can receive data link information from both 1090 ES transponders and UATs.
TIS-B traffic may be displayed with degraded positional accuracy. Aircraft
without operating transponders are invisible to TIS-B. Aircraft operating
outside of the ATC radar coverage area are also not displayed.
Since the GDL 39 is a receive-only device, even when used onboard an aircraft
equipped with a qualifying GPS and 1090 ES transponder, a GBT may not identify it as
an ADS-B participating aircraft. The squitter of some 1090 ES transponders, including
the Garmin GTX 330, must be configured to communicate that the aircraft has 978
MHz receive capability in order to be identified as an ADS-B participating aircraft.

Additional Features
The GDL 39 automatically adjusts its Traffic Advisory (TA) sensitivity level to reduce
the likelihood of nuisance TA alerts during various phases of flight. TAs are issued for
traffic when they are predicted to be within a specified volume of airspace around your
aircraft in a specified amount of time. The protected volume and time interval varies
based on the current geodetic altitude and groundspeed. Thus, the protected volume
of airspace increases with altitude and ground speed. Refer to the following table for
details.

TRAFFIC ALERTS (ADS-B TIS-B)
A traffic audio alert is generated whenever the number of Traffic Advisories on the
aera 795/796 display increases. Limiting Traffic Advisories only reduces the “nuisance”
alerting due to proximate aircraft. For example, when the first Traffic Advisories appear
on the display, the user is alerted audibly. So long as a single aircraft remains on the
display, no further audio alert is generated. If a second (or more) aircraft appears on
the screen, a new audio alert is sounded. Traffic Advisories can only be issued when
the GDL 39 knows its own altitude and the altitude of the intruder aircraft.
If the number of Traffic Advisories on the traffic display decreases and then increases,
a new audio alert is sounded. The traffic audio alert is also generated whenever TIS-B
service becomes available. The following traffic audio alerts are available:
• “Traffic”—TIS-B/ADS-B traffic alert received.

MOTION VECTORS
There are two pilot-selectable and mutually exclusive types of motion vectors, Absolute
and TargetTrend, which are differentiated by color and function. Absolute vectors are
white and indicate ground track as reported by the traffic. TargetTrend vectors are green
and indicate the flight path and position, relative to your aircraft, at which the traffic
will be after the passing of one of four predetermined time intervals. The end of the
TargetTrend vector indicates the traffic's predicted location relative to your predicted
location at the end of the look-ahead time. For example, if traffic is ahead of you and
traveling along the same track but at a slower rate, the motion vector would point
opposite of its indicated direction of flight showing that you are overtaking the traffic.

5.1 3D VISION
WARNING: Use appropriate systems for navigation, and for terrain, obstacle,
and traffic avoidance. 3D Vision does not provide either the accuracy or
reliability upon which to base decisions and/or plan maneuvers to avoid
terrain, obstacles, or traffic.
3D Vision is a visual enhancement to the aera 795/796. 3D Vision depicts the
topography as seen from outside the aircraft. The depicted imagery is derived from
the aircraft's three-dimensional position, and databases of terrain, obstacles, and other
relevant features. Loss of the GPS signal, will cause 3D Vision to be disabled until it
is restored.
The 3D Vision terrain display shows land contours (colors are consistent with those
of the topographical map display), large water features, towers, and other obstacles
over 200’ AGL that are included in the obstacle database (if present). Cultural features
on the ground such as roads, highways, railroad tracks, cities, and state boundaries
are not displayed even if those features are found on the Navigation Map. The terrain
display also includes a north-south east-west grid with lines oriented with true north.
Terrain is integrated within 3D Vision to provide visual and auditory alerts to indicate
the presence of terrain and obstacle threats relevant to the projected flight path.
Terrain alerts are displayed in red and yellow shading.
3D Vision does not provide the accuracy or fidelity on which to base decisions and
plan maneuvers to avoid terrain or obstacles. Navigation should not be predicated
upon the use of the terrain or obstacle data displayed by 3D Vision.
Touch and drag the three-dimensional view to change the perspective.

The figure below, shows examples of off-scale areas, indicated by the grey shading.
Note, the grey shading is for illustrative purposes only and will not appear on the
published chart or display. These off-scale areas appear on the chart to convey
supplemental information. However, the depicted geographical position of this
information, as it relates to the chart planview, is not the actual geographic position.
Therefore, when the aircraft symbol appears within one of these areas, the aircraft
position indicated is relative to the chart planview, not to the off-scale area.
Flight Planning
The geo-referenced aircraft position is indicated by an aircraft symbol displayed on
the chart when the current position is within the boundaries of the chart. Inset boxes
are not considered within the chart boundaries. Therefore, when the aircraft symbol
reaches a chart boundary line, or inset box, the aircraft symbol is removed from the
display.
GPS Navigation
ChartView resembles the paper version of Jeppesen terminal procedure charts. The
aircraft position is displayed on the moving map in the plan view of the approach
charts and on airport diagrams.

present that is not represented on the display.
TIS-A relies on surveillance of the Mode-S radar system, which is a “secondary
surveillance” radar system similar to that used by ATCRBS. Many limitations are
inherent in secondary radar surveillance. Information provided by TIS-A is neither

TIS-A LIMITATIONS
Appendices
The main difference between the Traffic Information System (TIS-A) and Traffic
Advisory (TAS) or Traffic Collision Avoidance Systems (TCAS) is the source of surveillance
data. TAS/TCAS uses an airborne interrogator with a half-second update rate, while
TIS-A utilizes the terminal Mode-S ground interrogator and accompanying data link to
provide a five-second update rate. TIS-A and TAS/TCAS have similar ranges.
Additional Features
TIS-A VS. TAS/TCAS
Hazard Avoidance
The Traffic Information Service (TIS-A) provides traffic advisory information to nonTAS/TCAS-equipped aircraft. TIS-A is a ground-based service providing the relative
locations of all ATCRBS (Air Traffic Control Radar Beacon System) Mode-A and Mode-C
transponder equipped aircraft within a specified service volume. The TIS-A ground
sensor uses real-time track reports to generate traffic notification. The aera 795/796
displays TIS-A traffic information on the Navigation Map. Surveillance data includes all
transponder-equipped aircraft within the coverage volume. The aera 795/796 displays
up to eight traffic targets within a 7.5-nm radius, from 3,000 feet below, to 3,500 feet
above the requesting aircraft.

WARNING: Do not rely solely upon the display of traffic information for collision
better nor more accurate than the information used by ATC. TIS-A is intended only to
assist in visual acquisition of other aircraft in visual meteorological conditions (VMC).
While TIS-A is a useful aid for visual traffic avoidance, system limitations must be
considered to ensure proper use. No recommended avoidance maneuvers are given,
nor authorized, as a direct result of a TIS-A intruder display or TIS-A advisory.
•TIS-A operation may be intermittent during turns or other maneuvering.
•TIS-A is dependent on two-way, line-of-sight communications between the aircraft
and the Mode-S radar antenna. Whenever the structure of the aircraft comes
between the transponder antenna and the ground-based radar antenna, the signal
may be temporarily interrupted.
NOTE: Refer to the TIS-A Limitations section of the Aeronautical Information
Manual (AIM) for a more comprehensive explanation of limitations and
anomalies associated with TIS-A.

Overview
Appendix F
NOTE: TIS-A is unavailable at low altitudes in many areas of the United States.
This is often the case in mountainous regions.
NOTE: Garmin is not responsible for Mode S geographical coverage. Operation
of the ground stations is the responsibility of the FAA. Refer to the AIM for a
Terminal Mode S radar site map.
TIS-A information is collected during a single radar sweep. Collected information
is then sent through the Mode S uplink on the next radar sweep. Because of this,
the surveillance information is approximately five seconds old. TIS-A ground station
tracking software uses prediction algorithms to compensate for this delay. These
algorithms use track history data to calculate expected intruder positions consistent
with the time of display. Occasionally, aircraft maneuvering may cause variations in
this calculation and create slight errors on the Navigation Map which affect relative
bearing information and the target track vector and may delay display of the intruder
information. However, intruder distance and altitude typically remain relatively
accurate and may be used to assist in spotting traffic. The following errors are common
examples:

These are rare occurrences and are typically resolved within a few radar sweeps once
the client/intruder aircraft course stabilizes.

Flight Planning
Pilots using TIS-A can provide valuable assistance in the correction of malfunctions
by reporting observations of undesirable performance. Reports should identify the time
of observation, location, type and identity of the aircraft, and describe the condition
observed. Reports should also include the type of transponder and transponder
software version. Since TIS-A performance is monitored by maintenance personnel,
not ATC, malfunctions should be reported in the following ways:
GPS Navigation
•When a rapidly closing intruder is on a course that intercepts the client aircraft
course at a shallow angle (either overtaking or head-on) and either aircraft abruptly
changes course within 0.25 nm, TIS-A may display the intruder aircraft on the
incorrect side of the client aircraft.
Overview
•When the client or intruder aircraft maneuvers excessively or abruptly, the tracking
algorithm may report incorrect horizontal position until the maneuvering aircraft
stabilizes.

Additional Features
Your current location can be viewed on the GPS in the form of coordinates. Since
different charts use different location formats, Garmin GPS units allow you to choose
the correct coordinate system for the type of chart you are using. The most common
format is latitude and longitude, which is used by all Garmin units. You can change the
location format to use with other coordinate systems. Several other grids, including a
user-definable grid (for the advanced user), are available.

LOCATION FORMATS
GPS Navigation
A datum is a mathematical model of the Earth that approximates the shape of the
Earth and enables calculations to be carried out in a consistent and accurate manner.
The datum is physically represented by a framework of ground monuments (such as
trig. stations) whose locations have been accurately measured and calculated on
