What is the squawk code for a hijacking situation?

The squawk code for a hijacking situation is 7500. This specific transponder code is universally recognized within aviation communications and protocols. When an aircraft is in a situation where it is being hijacked, the crew may enter this code to alert air traffic control and other aircraft that there is a serious threat to the safety of the flight. The use of this code allows authorities to quickly and discreetly identify and respond to the emergency situation.

In contrast, other codes such as 7600 indicate a radio communication failure, while 7700 signifies an emergency situation that is not necessarily related to hijacking, like an urgent mechanical issue. The squawk codes are standardized within aviation regulations to ensure that pilots and air traffic controllers can communicate effectively and respond appropriately during various emergencies.
