### Objective Understand purpose and procedures of a chandelle. Develop skills required to execute a chandelle to ACS standards. ### References - [[Commercial ACS]] Sec V.C - [[AFH Ch10]] - [[All Maneuvers Quick Reference]] ### Builds On - [[PPL2.1 Slow Flight and Power-Off Stalls]] ### Schedule Ground 0.5 hr, Flight 2.0 hr ### Lesson Elements > [!maneuver]- 3D Visualizer: Chandelle > <iframe src="https://maneuvers.cfijack.com/?embed&m=chandelles" width="100%" height="520" style="border:0;border-radius:12px"></iframe> 1. Purpose 1. The goal is to gain the most altitude possible for a given bank angle and power setting 2. **However**, the standard used to judge the maneuver is not the amount of altitude gained, but rather the pilot’s proficiency in maximizing climb performance 2. Technique ![[Chandelle.jpeg]] 1. A maximum performance, 180° climbing turn 2. Begins from approximately straight-and-level flight 3. Concludes with the airplane in a wings-level, nose-high attitude just above stall speed 3. Flying the Maneuver 1. Clear Area, Start > 1500 AGL, pick 0, 90, and 180 reference points 2. Establish cruise at Va (or POH recommendation), gear and flaps UP. 3. Constant-Speed prop – leave at cruise power during maneuver 4. Enter 30° bank turn, with continuous slow pitch up 5. Set power: (Fixed-pitch – slowly add full power during pitch up. Constant-Speed prop – leave at cruise power during maneuver) 6. At 90° point, reach max pitch attitude and hold it 7. From the 90° point to the 180° point, continuously reduce bank angle from 30° back to wings level, while maintaining that same max pitch attitude 8. Wings should become level just as the 180° point is reached. Airspeed should be just above Vs1 9. Hold Vs1 momentarily, then recover to cruise flight, maintaining altitude. ### Common Errors - Letting pitch increase too quickly at the onset of the maneuver - Letting the pitch sag during the second half of the maneuver - Rolling out too suddenly ### Completion Standards Learner is able to rollout at the 180° point, ±10°, and just above a stall airspeed, then maintain that airspeed momentarily while avoiding a stall. Recover to cruise flight, maintaining altitude. ### Required Logbook Phraseology [[FAR 61.127 CPL Flight Reqs]]: - Performance maneuvers ### Required Homework None ### Recommended Homework - [ ] Demonstrate the maneuver using a model airplane - [ ] Chair fly chandelle *Return to [[~ CPL Lesson Plan Outline|Table of Contents]]^*
