According to website Aviation Matters, a 'squawk code' is a code assigned by Air Traffic Control that pilots enter into their transponder that identifies the aircraft on the controllers screen.
A 7700 is a squawk code that is reserved for emergency situations and immediately alerts Air Traffic Control (ATC) and other units that the aircraft squawking 7700 is in distress.
