I was obtaining my departure clearance the other day (UK) and we were allocated a squawk code of 7701. I did not query it at all but I felt that it was a bit close to the emergency code in that in flight it is not beyond plausibility that the 1 switch could be moved accidently to 0 by fingers, a food tray or some other reason. Highly unlikely but a chance nevertheless. Surely out of the thousands of codes available, why give one so close to 7700?? If we had incorrectly set it and it had turned the radar screen red (?) and there had been lots of frantic calls here and there, would this sort of code continue to be in use for a standard flight? Also I have as I sure others have had 760* and 750* from departure clerance. Thank you for your replies.
