What is the main goal of the terminate call in the absence of safety issues?

The primary purpose of the terminate call is to indicate that a particular maneuver or training objective has been satisfactorily achieved. In a training context, this call signifies that the instructor has determined that the learning objectives for that specific phase of flight have been met, allowing the student to recognize their progress and readiness to move on to another task or maneuver.

This approach helps to structure the training session effectively, ensuring that time is spent efficiently and that the student receives timely feedback on their performance. The focus is on delivering quality instruction and ensuring that learning is taking place, rather than on procedural steps such as changing frequencies, preparing for landing, or signing off from a flight, which do not directly relate to the educational objectives of the training session.
