Which of the following is a method used to dissipate excess energy during the glide to high key position?

All the listed methods – minimum descent rate, power reduction, and dragging the aircraft – can be effectively used to dissipate excess energy during the glide to the high key position.

Minimum descent rate involves maintaining a configuration that allows the aircraft to lose altitude at the slowest possible rate. By optimizing the aircraft’s lift-to-drag ratio, pilots can manage their energy and control their descent during approach. This method is crucial when approaching the high key position, which aids in managing glide performance effectively.

Power reduction refers to the gradual reduction of engine power to decrease the aircraft’s airspeed and kinetic energy. It is a necessary technique that helps pilots to manage their energy state, ensuring they do not overshoot the intended glide path or altitude at high key.

Dragging the aircraft can involve extending the landing gear or flaps, which increases drag and decreases airspeed. By employing this technique, pilots can effectively reduce altitude and energy, allowing for more precise control during the descent.

Utilizing all these methods in conjunction can help a pilot manage the aircraft’s energy more effectively when transitioning to the high key position, ensuring safe and controlled flight operations.
