The ICAO transponder emergency distress code is 7700 while hijacking is (I think??) 7200. There's also one for NORDO (No Radio) which I think is 7600. 7500 for hijack. Your other guesses are correct. 77 and 76 came from the old 64 code days. Back when there was only 10 airplanes within a hundred miles of an airport :-) 00 was the intercept code, and 11 was the interceptor weapons free code (nuclear). 12 was contact flying below 12kft. |
