What is the appropriate response from the flight crew during a hijacking?

During a hijacking, the appropriate response from the flight crew involves securing the flight deck, which is effectively achieved through flight deck door lockdown. This procedure is critical for ensuring the safety of the pilots and maintaining control of the aircraft. By locking the flight deck door, the crew can prevent unauthorized access and protect themselves from potential threats posed by hijackers.

This response is part of a broader set of protocols designed to respond to such critical incidents, focusing on maintaining control of the aircraft rather than taking potentially dangerous actions like an emergency landing or passenger evacuation, which may put passengers at greater risk. Locking down the flight deck helps to create a secure environment from which the flight crew can assess the situation and communicate with air traffic control, enabling them to manage the incident more effectively.
