AMC 20-24 Compliance
The TT21 or TT22 transponder can be connected to the following GPS units to form the basis of
an AMC20-24 compliant ADS-B installation:

Freeflight 1201 & 1204 WAAS/GPS Sensors

NexNav MINI & NexNav MAX WAAS/GPS Sensors

Garmin GNS 400W/500W series
For installations seeking certification to AMC 20-24 or other applicable standards, additional

Automatic Air/Ground Determination
The SV-XPNDR-261/262 can report ADS-B surface and airborne messages. This can be
accomplished via a squat switch input that is designed to be used with an automatic air/ground
switching device, or via automatic detection. These options are fully explained in the SV-
XPNDR-261/262 Installation, Configuration, and Testing Section of this guide.
