View Full Version : What's a chandelle?

I've been reading James Duffy's account of flying the Hellcat in this months Flypast magazine (wetting the appetite for PF), and a couple of times he refers to a maneouver that he calls a chandelle. Just wondered what it is.

Thanks

From http://www.iac.org/begin/figures.html
"The Chandelle is not used in aerobatic competition. On the FAA power commercial pilots test a Chandelle is defined as a maximum performance climbing turn through 180 degrees while maintaining a constant turn rate. The idea is that this is a "plan ahead" maneuver. You first establish a medium bank depending on the performance of your aircraft. Then a smooth pullup is started. The angle of bank stays constant during the first 90 degrees of turn, while the pitch angle increases steadily. At the 90 degree point the plane has the maximum pitch angle which should be close to the critical angle of attack. During the second 90 degrees of turn, the pitch angle is held constant, while the bank angle is smoothly decreased to reach 0 degrees of bank at 180 degrees of turn with the airspeed close to the stall speed. The plane should not settle during the last part of the maneuver and the recovery. The decreasing bank angle during the second half of the Chandelle will maintain a constant turn rate together with the decreasing airspeed. The turn needs to be kept coordinated by applying the right amount of rudder. A Chandelle to the left is quite different than one to the right because of the ever increasing amount of p-factor in the second half of the maneuver."
