Chanda, N., "Redundant Transmitting System in Aircraft (RTSA)," SAE Technical Paper 2015-01-2443, 2015, doi:10.4271/2015-01-2443.
Aircrafts use Transponder for transmitting data to Air Traffic Control ground stations. Transponders automatically transmit a unique four-digit code when they receive a radio signal sent by radar. But when Transponder is shut down, and the redundant transponder fails to operate, there is no system within the aircraft which can continue transmitting altitude and important data to ATC ground stations. This has necessitated active research work to fundamentally design better and effective communication systems. At present, there is no evident redundant system to transponder unlike in case of Power-Plants, three-fold reliable, safety cum redundant power supply system are present. The present work introduces a novel design ‘RTSA’ which can be effective in catering safe transmission of emergency signal.
