Description
A.
ADS-B OUT System with Dual Transponder System (Diversity or Non-Diversity).
(1) The Dual Transponder System, both transponders are the Enhanced Mode S
transponders with or without the antenna diversity by Garmin, models GTX–33(D).
Both transponders, XPDR 1 and XPDR 2, are located behind the Instrument Panel

located in the cockpit on the lower left instrument panel.
3.
Operation
A.
The ADS-B OUT system utilizes the Extended Squitter (ES) capability of the
transponders.
GPS 3 (GDL 88) with internal GPS provides the necessary ADS-B OUT compliant
position data to the already installed transponders. GPS 3 outputs the ADS-B OUT
compliant GPS data to both transponders via a dedicated RS-232 line.
B. GPS 3 (GDL 88) makes use of the GPS 2 antenna through the GPS 2 Antenna Splitter,
which is located below the aft baggage compartment floor.
C. The ADS-B system failure indicator provides an advisory message to the pilot via a white
ADS-B FAIL indication if any of the following events occur:
• GPS 3 loses its integrity
• During R Smoke Clear procedure
• Manually pulling ECB
• Battery-only Load shed
• Unintended power loss
