What does this code mean?
With 7600 the crew signals that the radio isn't working, or that they can no longer hear air traffic control. The aircraft then follows its last clearance and a fixed procedure, and air traffic control keeps the airspace around it clear. The tower can use light signals. Often it is a broken radio or a wrongly set frequency, and contact is restored within minutes.
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:
