SECTION 12 FDL-978 LITE SERIES

12.1 General System Description

The FDL-978 Lite Series includes the FDL-978-XVRL Transceiver (ADS-B Out & In) with
FWF-125 Wi-Fi Module and the FDL-978-TXL Transmitter (ADS-B Out only). The FDL-
978-XVRL transmits ownship position, velocity, and flight data (ADS-B Out) and receives
position, velocity, and flight data from other aircraft and ground station equipment (ADS-
B In) via a UAT data link. The FDL-978-XVRL satisfies the TSO requirements referenced
in Section 1.1 and the associated MOPS for UAT ADS-B class A1S equipment. The
FDL-978-TXL has transmit capability only and satisfies the TSO requirements for UAT
ADS-B class B1S equipment.
The FDL-978 Lite Series contain an integrated GPS to provide all necessary position and
velocity data, allowing it to be used in aircraft that are not equipped with a GPS. Existing Garmin
GTX transponders can be used to input squawk codes, IDENT, and mode. A compatible
serialized altitude encoder can be used to provide pressure altitude. The FDL-978-XVRL also
can provide TIS/FIS data to the cockpit on the pilots PED (e.g. iPad or Android device) through
a Wi-Fi connection.
If the aircraft does not have a transponder or altitude encoder, the FDL-978 Lite Series products
come with the TC978 control head. The TC978 provides all control input for squawk, IDENT,
call sign, mode, and altitude inputs required for ADS-B compliance.
The FDL-978-XVRL Transceiver provides both UAT transmit and receive (ADS-B In/Out) and
GPS capabilities. The transceiver part number covered by this installation manual is:
•
87098-00-FX0L
The FDL-978-TXL Transmitter provides UAT transmit (ADS-B Out) and GPS capabilities. The
Transmitter part number covered by this installation manual is:
•
87098-00-FT0L
These units include four status LEDs, serial interfaces (controller input, altitude encoder input,
and Wi-Fi Module interface), and discrete inputs/outputs.
