In all cases, uncompensated latency due to the transponder is less than 10
milliseconds. Analysis of the system latency should add this to the latency of the
GPS system and the transmission time of the position data from the GPS to the
transponder to determine the overall latency.
1.28 FAA 91.227 Compliance
