15.1 Equipment Description
The GPS 20A provides an ADS-B Out position source. The WAAS/SBAS position information is
compatible with a wide range of 1090 ES transponders to meet the position requirements of
14 CFR 91.227. The GPS 20A also provides position data to all G3X™ avionics and G3X Touch™
avionics displays.
NOTE
If a GPS 20A (and connected GA 35, GA 36, or GA 37 antenna) is used for GPS position,
additional GPS antennas (connected to GDU™ 37X/4XX display units) may be used for
redundancy, but are not required.
NOTE
The GPS 20A is not an FAA-approved product and thus is not eligible for installation in
certified aircraft.
