主旨摘要
- A design deficiency causes the transponder to revert to standby mode if a change of the 4096 ATC code (also referred to as the Mode A code) is not completed within 5 seconds. As a consequence, the SSR radar symbol and label associated with the aircraft’s position will no longer be shown on the ATC ground radar display. Also, aircraft collision avoidance systems (ACAS) on board own and other aircraft will be comprimised. Current operational procedures, typically, do not require the crew to recheck the transponder status after changing the
4096 ATC Code. This type of failure will increase ATC workload and will result in improper functioning of ACAS.
