G. TAWS/RWS and Transponder Digital Output Data
(1) GCAM Event Data
The T
3
CAS TAWS events are caused by terrain and weather conditions. An
event begins when a terrain or weather condition causes the T
3
CAS to declare a
TAWS caution or warning alert or when the aircraft telemetry causes a Bank
Angle Callout. This data is recorded each time an alert occurs (caution or
warning) and contains information about the triggering event. The T
3
CAS then
transmits the GCAM Event Data over one of the programmable ARINC 429
output busses in 10.
Table 4-58 shows the GCAM Event Data Labels transmitted on the A429 output
Bus.
