Which of the following methods is NOT used to dissipate excess energy during the glide to high key position?

The method of dissipating excess energy during the glide to the high key position that is not typically used is clearing turns. Clearing turns are primarily performed to ensure that the area around the aircraft is clear of other traffic before maneuvering, rather than being a specific method for energy management during a glide.

In contrast, slips or S-turns, 360° turns, and lowering the gear early or extending the speed brake are all techniques designed to effectively lose altitude and reduce airspeed in a controlled manner as the aircraft approaches the high key position. These methods directly impact the aircraft’s energy state, providing a way to manage it to complete a safe landing approach.

By focusing on techniques that involve changes in flight path or configuration adjustments, pilots can actively control their energy and ensure they reach the desired position in a safe manner.
