What is the expected energy gain/loss when performing a chandelle maneuver?

In a chandelle maneuver, the aircraft is executed in a climbing turn which typically results in an increase in potential energy due to the climb. As the pilot performs the maneuver, the aircraft gains altitude while also achieving a change in direction. This combination of a climb and a turn means that more lift is required to sustain the maneuver, which can increase drag.

However, the primary intent of the chandelle is to end in a higher altitude and maintain controlled flight, thereby resulting in an overall gain in potential energy. This is why the expected energy gain during a chandelle maneuver is categorized as gaining energy. While adjustments in airspeed and maneuvering can influence drag and performance, the overall outcome of the chandelle is designed to increase altitude, clearly illustrating that the correct answer is gaining.

In contrast, neutral, losing, and variable do not accurately capture the energetic outcome of a well-executed chandelle, which is primarily focused on climbing and turning simultaneously.
