Chandelle

Chandelle is an advanced aerobatic maneuver and flight training exercise that combines elements of climbing and turning, demonstrating a pilot's skill in controlling the aircraft under varying conditions. The term "chandelle" originates from the French word for candle, which metaphorically represents the maneuver's appearance from the ground—a smooth, graceful ascent and turn, resembling the shape of a candle flame.

Description

The chandelle is executed by the pilot initiating a steep climb at full power while simultaneously banking into a turn. The goal is to achieve the maximum possible change in direction—up to 180 degrees—while losing as little airspeed as possible and not stalling the aircraft. The maneuver is completed when the aircraft reaches the apex of the climb, at which point it should be nearly at a stall speed, and then it is leveled off smoothly.

Purpose and Application

The chandelle is used as a training exercise to teach pilots about aircraft handling at the edge of its performance envelope, particularly in managing stall and spin conditions. It also enhances a pilot's ability to control the aircraft through a combination of maneuvers, which is essential for emergency situations, combat flying, and aerobatic performance. In practical terms, a chandelle can be used to quickly change direction and altitude simultaneously, which could be useful in avoiding terrain or an obstacle.

Technique

To perform a chandelle, the pilot must: 1. Enter the maneuver at cruise speed and begin a climbing turn into the wind. 2. Apply full power to increase the rate of climb and maintain a constant bank angle. 3. As the aircraft's speed decreases, gradually reduce the bank angle to maintain lift and prevent stalling. 4. Near the top of the climb, as the airspeed approaches stall speed, level the wings and ease the nose down to exit the maneuver in level flight.

Proper execution of the chandelle requires precise control of the throttle, rudder, and ailerons to maintain the desired flight path and airspeed.

Training and Safety

The chandelle is taught in advanced flight training programs and is a required maneuver for certain pilot certifications. Pilots must practice under the supervision of a qualified flight instructor to ensure safety and mastery of the technique. It is critical to perform the chandelle in an area clear of obstacles and with sufficient altitude to recover from a stall should one occur during the maneuver.

In Popular Culture

While primarily a training and performance maneuver, the chandelle has been featured in various forms of popular culture, including movies and airshows, showcasing the skill and precision of pilots.
