The next time you introduce a student to stalls in a turn, try the following. Begin by telling the student that stalls often occur when a pilot is distracted. Reduce power as if you're approaching to land while in the traffic pattern. Tell the student that ATC has just asked you to follow an airplane on base leg. Explain to the student that, as you're looking for traffic, you overshoot your turn to final and attempt to steepen up the turn. As you do, the airplane exceeds its critical angle of attack and stalls. Voil�! Context has given the maneuver meaning.
Now your students will be more likely to remember the activity. They are also more likely to be motivated to learn other maneuvers when it becomes apparent that these activities aren't just useless exercises designed to satisfy some bureaucrat's idea of what makes flying safe.
You can apply context to everything you teach. Take turns about a point, for instance. After you introduce your students to the fundamentals of the maneuver, show them its value during a forced landing. Explain that when circling down over a landing site after an engine failure, they will be able to check for wind drift based on the principles that this maneuver teaches. This will help determine the proper landing directions. For instance, the portion of their constant-radius descending turn that requires the steepest bank represents the downwind direction. This means that a landing should be attempted in the opposite direction if possible.
Context is everything when it comes to making flight training maneuvers meaningful to your students. With a little thought and careful preparation, you should be able to present every flight training maneuver in a meaningful context. Your students will really appreciate it.
