Section 1. GENERAL
1.1 GDL 82
The Garmin GDL 82 UAT Datalink Transmitter is a remote-mounted ADS-B Out
UAT transmitter designed to complement an existing Mode A/C transponder to
meet regulation 14 CFR §91.225 and §91.227 in accordance with AC 20-165B.
The GDL 82 transmits the ADS-B Out UAT message through a shared L-band
antenna while momentarily suppressing the Mode A/C output of the companion
transponder. When the GDL 82 is not transmitting, the Mode A/C transponder
operates normally. Depending on the model, the GDL 82 can either use its own
internal GPS/SBAS receiver or another approved external GPS/SBAS source.
The GDL 82 performs the following functions:
•
Transmission of ADS-B out data on 978 UAT (978 MHz)
o
•
Integration of data from internal and external sources to transmit the
following data per 14 CFR §91.227:
▪
GPS Position, Altitude, and Position Integrity
▪
Ground Track and/or Heading, Ground Speed, and Velocity Integrity
▪
Air/Ground Status
▪
Flight ID, Call Sign, ICAO Registration Number
▪
Capability and Status Information
▪
Transponder Squawk Codes between 0000-7777.
▪
Emergency Status
▪
IDENT - initiates SPI (Special Position Identification) pulse for 18
seconds
“Anonymous” mode (optional) transmits a temporary address instead of the
aircraft’s-assigned ICAO 24-bit address and “VFR” instead of the aircraft’s
registration number, when the interfaced Mode A/C transponder is set to the VFR
code, “1200”.

Section 2. LIMITATIONS
2.1
Required Equipment
The GDL 82 must have the following system interfaces fully functional to be
compliant with the requirements for 14 CFR §91.227 ADS-B Out operations:

2.2
ADS-B OUT
The GDL 82 will only comply with 14 CFR §91.227 for ADS-B OUT when all the
above required equipment are operational. If the optional ADS-B OUT FAIL
annunciator is installed, it will illuminate when the GDL 82 is not transmitting a
valid or complete ADS-B OUT message.
2.3
Maximum Operating Altitude
In accordance with 14 CFR §91.225, aircraft with ADS-B Out UAT equipment,
operating on 978 MHz and meeting the requirements in TSO-C154c, are limited to
operations below 18,000 feet MSL.
Aircraft Operational Ceiling:
 18,000 feet (UAT Operating Altitude Limit per AC 20-165B)
 15,000 feet (Class B Transponder Equipment Operating Altitude Limit per 14
CFR Part 91.413)

2.4
Anonymous Mode Operation (if installed)
In the event the GDL 82 is installed with an ADS-B In device (e.g., GDL 39), when
the GDL 82 anonymous mode is initially enabled, the ADS-B In receiver may
detect the aircraft’s registration number change as a nuisance ownship shadow and
report a traffic alert (TA) at the aircraft’s location and altitude. This is due to the
aircraft’s identification changing from the known registration number to “VFR” and
a temporary address.
It is not recommended to enable the anonymous mode during flight. To enable the
anonymous mode, it must be activated on-ground to avoid receiving an ownshipshadow TA.
Anonymous Mode Switch Installed:
 YES (comply with anonymous mode operation limitations in AFMS)
 NO

Section 3. EMERGENCY PROCEDURES
3.1
Emergency Procedures
No Change.
3.2
3.2.1
Abnormal Procedures
LOSS OF AIRCRAFT ELECTRICAL POWER GENERATION
When the aircraft electrical charging system becomes inoperative or degraded,
avionics will continue to operate for a limited time using aircraft battery power.
The pilot should become familiar with electrical load-shedding methods and
equipment requirements for the various phases of flight. If an electrical emergency
exists or the aircraft’s charging system is compromised, the pilot should consider
turning off the GDL 82 to preserve the operation of more essential avionics when
using only battery power.
Subject to aircraft equipment electrical load-shedding priorities,
XPDR UAT Circuit Breaker Position ............................................... CONSIDER
NOTE
Pulling the XPDR UAT circuit breaker will turn off both the GDL 82 and the
companion transponder. ADS-B OUT UAT and transponder functions will no
longer be available. Also, without power, the GDL 82’s ADS-B OUT FAIL
annunciator will not illuminate.
This guidance is supplementary to any guidance provided in the Pilot’s Operating
Handbook (POH) for the Mooney M20-series aircraft for loss of power generation.
3.2.2 LOSS OF GPS/SBAS POSITION DATA
When the configured GPS/SBAS receiver is inoperative or GPS position
information is not available or invalid, the GDL 82’s ADS-B OUT FAIL
annunciator will illuminate. In this case, though the GDL 82 will continue to
transmit ADS-B OUT UAT data without a valid GPS position, the ADS-B OUT
message is neither complete nor compliant.
ADS-B OUT FAIL Annunciator (if installed)………………ILLUMINATED
For GDL 82 installations that use an external GPS position source:
Interfaced GPS position source................................................ VERIFY GPS
POSITION SOURCE IS ON AND FUNCTIONING PROPERLY WITH A
VALID POSITION

Section 4. NORMAL PROCEDURES
The GDL 82 requires no pilot intervention or control for normal operation. The
GDL 82 is powered on with avionics and will automatically begin to operate once
the configured Mode A/C transponder is set to ALT and a GPS/SBAS position is
available.
The pilot may select the Anonymous Mode if the optional Anonymous Mode
switch is installed and the transponder code is set to “1200”.
4.1
GDL 82 Unit Power On
Avionics Master ............................................................................................... ON
Transponder ................................................................................... Code set, ALT
Anonymous mode switch (if installed) ........................................... AS DESIRED
ADS-B OUT FAIL annunciation (if installed) ........................ EXTINGUISHED
NOTE
AIM 4-1-20 a. 3. encourages pilots to operate with the transponder in the altitude
reporting mode and ADS-B Out transmissions enabled (if equipped) at all airports,
any time the aircraft is positioned on any portion of an airport movement area.
If the ADS-B OUT FAIL annunciator is installed, it may illuminate momentarily as
the unit powers on and begins to receive input from external systems, including the
GPS/SBAS position source. Ensure lamp is operational prior to flight by pressingto-test.
The configured Mode A/C transponder must be set to ALT and the optional ADS-B
OUT FAIL annunciation must be EXTINGUISHED for the system to meet the
requirements specified in 14 CFR §91.227. This system must be operational in
certain airspaces after January 1, 2020 as specified by 14 CFR §91.225.
