Which of the following is not a responsibility of the Air Boss?

The role of the Air Boss, also known as the Air Officer, is primarily focused on managing the operations on an aircraft carrier's flight deck. This includes overseeing the launch and recovery of aircraft, ensuring that flight deck operations run smoothly and safely, and coordinating various elements of air traffic in the vicinity of the carrier.

Determining glideslope refers to the vertical path that an aircraft follows during an approach for landing. This responsibility typically falls to the pilots and other roles directly involved in the landing approach, rather than the Air Boss. While the Air Boss is responsible for overseeing the launch and recovery processes and ensuring effective communication with pilots, the actual management of glideslope is not within their direct purview. Therefore, this choice correctly identifies an area that is outside the scope of the Air Boss's responsibilities.
