Do aircrews need to report high key every time they orbit after being directed to do so?

Aircrews are required to report high key each time they orbit after being directed to do so. This is essential for maintaining situational awareness and ensuring that both the aircrew and the control tower are synchronized regarding the position of the aircraft. Reporting high key allows controllers to monitor the aircraft's progress during practice patterns, ensuring safe operations within the airspace and facilitating proper coordination for any subsequent instructions or maneuvers.

This requirement enhances communication, as it informs the controller when the aircraft is at a key point in the traffic pattern, thus ensuring that any necessary adjustments or clearances can be effectively managed. Regular reporting fosters a disciplined approach to flight operations, promoting safety and efficiency during training exercises.

The other options do not capture the necessity of consistent communication during each orbit, which could lead to misunderstandings and complicate air traffic management.
