What does this code mean?
With 7700 the crew declares an emergency. Air traffic control then gives the aircraft priority and space, and emergency services stand by at the airfield it is heading for. Common reasons are a technical problem (an engine, the hydraulics, cabin pressure, a warning in the cockpit), a sick passenger, or smoke or a strange smell on board. Often it is precautionary and the aircraft simply lands.
What was going on?
We don't know: a transponder only transmits the code, not the reason. A code can also be set briefly by mistake. If you want to know more, you can look further here:
