When should ATC initiate action to transfer the control of interceptor aircraft?

The correct choice emphasizes the importance of procedural protocol in air traffic control operations, particularly regarding the handoff of interceptor aircraft. Control transfers should be conducted when the aircraft reaches a designated control point or upon request from the Air Defense Command Facility (ADCF). This ensures that the interceptor is being managed in accordance with established airspace protocols and tactical needs.

When a control point is reached, it indicates that the interceptor is in a position where it can effectively engage or monitor a target, allowing for timely and coordinated actions. Additionally, an ADCF request indicates the operational authority’s need to maintain oversight or adjust the aircraft’s mission, ensuring proper communication and command structure within the military air operations framework.

Other scenarios, such as safety violations or aircraft being grounded, do not prompt a standard transfer of control, as they deal with immediate operational risk management rather than the structured transfer process. Conducting a fuel check is also a procedural task linked to aircraft readiness but is not directly related to the timing of control transfer, making it a less relevant choice in this context.
