transponder used signal emergencies such hijackings (7500). in event of hijacking pilot squawks 7500, universal code hijacking. instantly tells atc aircraft under duress, without knowledge of hijackers.

1 of reasons faa had problems tracking hijacked aircraft on 9/11 hijackers took direct control of aircraft , switched off transponders. leaves faint trace on radar screen no identification information , many specialized radars lose track of aircraft without transponder data. since 9/11, various rules changes have been proposed prevent transponder being turned off , lock 7500 squawk once it's been dialled in.
