What is the role of the instructor in a practical test scenario?

In a practical test scenario, the instructor's primary role is to evaluate and guide the student. This means that the instructor assesses the student's performance based on established criteria and provides constructive feedback throughout the testing process. The instructor's evaluations are crucial in determining whether the student has met the standards required for the practical test.

Guidance from the instructor can also help the student improve their technique and understanding of the maneuvers being tested. This support is valuable not only for the assessment at hand but also for the student's overall development in their flying skills. The effective guidance and evaluation facilitate a learning environment that encourages students to demonstrate their competence and confidence in their abilities.

While the other options touch on aspects of an instructor's duties, they do not encapsulate the core responsibility during a practical test. For instance, demonstrating maneuvers could occur, but the main focus should remain on the student's performance assessment. Additionally, completing maneuvers on behalf of the student would not contribute to an accurate evaluation of the student's skills, and merely observing and reporting does not engage the instructor's role in guiding the student's performance. Hence, the evaluation and guidance role stands out as the fundamental aspect of an instructor's function in a practical test scenario.
