Comparison Air Data Sensor
Type No. 3D731-A-2
Ref. No. V.A.A.S No. 202 (ET)
Ser. No. 126/64
In the Air Data Sensor static and dynamic pressure are sensed and three components are derived. The main outputs from the Air Data Sensor are duplicated but the outputs of the actual sensing capsule servos are compared with identical outputs from the Comparison Air Data Sensor designed by Elliott Bros. The alarm and disconnect circuits are activated when a discrepancy between the two signals exists.
The aircraft system has duplicated Comparison Air Data Sensors.
