What is expected from the intercepting aircraft if the intercepted aircraft cannot keep pace?

When an intercepting aircraft is tasked with following an intercepted aircraft that is unable to maintain speed or altitude, it is expected to visually signal the pilot of the intercepted aircraft. The correct protocol in this scenario includes flying a race-track pattern and rocking wings to indicate to the intercepted aircraft that it should acknowledge the presence of the interceptor. This visual signaling is crucial for ensuring that the intercepted aircraft is aware of the interceptor's intentions and can respond appropriately.

The practice of rocking wings serves as a non-verbal communication method that is easily recognizable and effective in ensuring that both pilots are aware of each other's statuses. By flying a race-track pattern, the intercepting aircraft demonstrates that it is maintaining a visual on the intercepted aircraft, which can be reassuring for the pilot of the intercepted aircraft who may be struggling to keep pace.

This method is part of a broader set of established protocols aimed at enhancing safety and clarity during such intercept scenarios, allowing the intercepted aircraft to understand what is being communicated and to follow the required evasion or compliance measures as necessary.
