What must be done if intercepted by another aircraft?

When an aircraft is intercepted by another aircraft, it is crucial to follow the instructions given by the intercepting aircraft. This is primarily for safety and security reasons, as interceptions typically occur under specific circumstances where one aircraft may need to verify the identity of another, often related to national security or airspace violations.

Following the instructions provided by the intercepting aircraft ensures compliance with air traffic control protocols and helps maintain order in the airspace. Such instructions may include directing you to land at a specific airport, changing your flight path, or other actions necessary to resolve the situation. Engaging cooperatively not only enhances safety but also fosters clear communication with the intercepting aircraft, which might be a military or law enforcement entity.

Visual contact with the intercepting aircraft is beneficial and can assist in understanding their intentions, but it should not take precedence over adhering to their instructions. Ignoring the aircraft entirely can lead to misunderstandings and could escalate the situation, while changing altitude immediately without guidance could complicate the scenario further without proper situational awareness. Thus, following the intercepting aircraft's directions is the appropriate and safe course of action.
