Why is a preflight briefing important in flight instruction?

A preflight briefing is important in flight instruction primarily because it sets expectations for the flight. This is crucial for both the instructor and the student pilot, as it helps establish a clear and mutual understanding of the goals, objectives, and structure of the upcoming flight. During the briefing, the instructor can communicate what the student should focus on, what maneuvers will be practiced, and what performance standards are expected. This clarity fosters a productive learning environment and helps the student prepare mentally for the flying experience.

While the other choices refer to aspects that might be included in a flight briefing, they do not encompass the primary purpose of setting expectations. A weather report is only one piece of information, and while it is important, the briefing itself covers a broader range of topics including safety, objectives, and skill acquisition. Similarly, a checklist of the aircraft and tools for air traffic control, although relevant, are secondary to establishing a clear and focused plan for the instructional flight.
