The chandelle stands apart from most training maneuvers because its purpose is not simply to practice a flight path — it is to extract the absolute maximum climb performance an airplane can produce while reversing course by 180 degrees, arriving at the slowest possible airspeed the moment the wings level. The Airplane Flying Handbook (FAA-H-8083-3) defines it explicitly as a maximum-performance climbing turn, and that word maximum carries real weight on both the commercial and flight instructor practical tests. For the flight instructor candidate, the chandelle represents a dual challenge: mastering the personal execution to ACS standards and simultaneously developing the ability to detect, explain, and correct the characteristic errors students produce. This article builds from first principles — aerodynamics, coordination, and timing — so you can teach the maneuver, not just fly it.
The Aerodynamic Foundation
Before breaking the chandelle into its two phases, it helps to understand what the airplane is doing aerodynamically throughout the maneuver. As the nose rises and airspeed decreases, the angle of attack increases. In a banked turn, the stall speed is higher than in wings-level flight because the wing must generate enough lift to support both weight and the centripetal force of the turn. The chandelle exploits this relationship deliberately: the bank is maintained through the first 90 degrees while pitch rises, then the bank is steadily removed in the second 90 degrees precisely because reducing bank lowers the stall speed, allowing the airplane to decelerate all the way to minimum controllable airspeed (MCA) without actually stalling. If the bank were held constant into the second phase, the airplane would stall well before the 180-degree point. This is why the two-phase structure is not arbitrary — it is aerodynamically necessary.
As airspeed decreases dramatically during the second phase, the propeller-related left-turning tendencies intensify. P-factor becomes pronounced as the descending propeller blade operates at a higher angle of attack. Torque reaction continues to roll the airplane left. Gyroscopic precession acts when the nose pitches up and the propeller disk precesses, producing a yawing force. All three demand progressive, increasing right rudder input — not a fixed deflection — as the second 90 degrees unfolds.
Phase-by-Phase Execution
Phase One: The First 90 Degrees of Turn
Entry begins at or below the manufacturer's recommended airspeed — typically maneuvering speed (VA) or a specific entry speed in the POH — to protect the airframe from overstress during the abrupt pitch change. The pilot simultaneously rolls to a 30-degree bank and begins a smooth, continuously accelerating pitch-up. The 30-degree bank is the standard for most training aircraft; a shallower bank reduces the rate of direction change and diminishes the performance demonstration, while an excessively steep bank increases stall speed during the first phase and can cause a stall before completion.
The critical requirement for phase one is timing: the nose must arrive at its maximum pitch attitude — the highest attitude the pilot can hold without stalling the airplane throughout rollout — exactly as the airplane completes the first 90 degrees of heading change. Reaching that pitch attitude early means the pilot must hold it longer, but cannot change it in phase two, causing the nose to drop as airspeed bleeds. Reaching it late means the pitch is still changing after the 90-degree point, which is a direct violation of the phase-two requirement. The pitch should feel like a smooth acceleration to a precise target, not a lurch or a lazy drift upward.
Phase Two: The Second 90 Degrees of Turn
At the 90-degree heading mark, the pilot freezes the pitch attitude — absolutely fixed — and begins rolling out of the bank at a constant rate calculated to reach wings-level precisely at the 180-degree point. The only control input changing during this phase is aileron (with coordinated rudder). The elevator holds the nose at its established attitude. The throttle remains at full power throughout the entire maneuver.
The rollout rate must be planned, not improvised. A pilot who waits until 150 degrees to begin rolling out aggressively will either stall or arrive wings-level well past 180 degrees. A pilot who starts rolling too early arrives wings-level before 180 degrees with excess airspeed — demonstrating that maximum performance was not extracted. The correct technique is to calculate a constant, uniform roll rate from 90 degrees all the way to 180 degrees, so that the control pressure feels steady and deliberate throughout.
At the 180-degree point, the completion standard is: wings level, coordinated flight, at MCA — sometimes called the slow flight speed or just above the stall warning. The airplane should feel on the edge, responding sluggishly but still controllably. If the airspeed is noticeably above MCA, either the pitch attitude was too low or the rollout was completed early.
Maximum Performance Criteria: Key Numbers and Standards
- Entry airspeed: At or below VA, or POH-specified entry speed. Starting too fast risks structural overstress; starting too slow leaves no margin to demonstrate deceleration to MCA.
- Bank angle: 30 degrees for most training airplanes, established simultaneously with the pitch-up.
- Pitch target timing: Maximum nose-high attitude reached at exactly the 90-degree heading mark — neither before nor after.
- Phase-two pitch: Absolutely constant. Zero pitch change is the standard. The horizon reference must be held without deviation.
- Rollout completion: Wings level at the 180-degree heading. ACS tolerances for the commercial certificate require completing the maneuver within plus or minus 10 degrees of the entry heading and rolling out at an airspeed within plus 5 knots of minimum controllable airspeed (but not below stall), with coordinated flight at completion.
- Power: Full throttle for the entire maneuver; carb heat off (if applicable) before entry.
- Coordination: Ball centered throughout, with progressively increasing right rudder during the second phase.
Common Pitch and Bank Coordination Errors
Pitch Errors
Pitch attitude not reached at 90 degrees. This is the most structurally damaging error because it corrupts everything that follows. If the nose is still rising at the 90-degree point, the pilot faces an impossible choice in phase two: hold that still-rising attitude (violating the constant-pitch standard) or stop the pitch early (meaning the target attitude was never reached). Instructors should watch the longitudinal axis during the first phase and note whether the pitch acceleration is smooth and timed to arrive at 90 degrees.
Allowing pitch to change in phase two. This is the most frequently tested error on knowledge and practical tests. Any nose movement — up or down — after the 90-degree point represents a loss of attitude discipline. Students commonly let the nose drop as airspeed decreases because the airplane feels heavy and they relax back pressure. The correct response is to maintain the same back pressure that established the pitch, recognizing that as speed decreases, the elevator becomes less effective and additional pressure may actually be needed to hold position.
Bank Coordination Errors
Non-uniform rollout rate. Students who do not plan the rollout rate in advance tend to roll too slowly through 90 to 150 degrees, then rush the last 30 degrees, producing an abrupt, skidding completion. The rollout must feel like a metered, constant unwinding of bank throughout the entire second 90 degrees.
Bank creep in phase two. Without deliberate aileron pressure, the bank may increase or decrease unintentionally. At low airspeeds, even small lateral control inputs produce noticeable bank changes. The instructor should observe the bank indicator continuously and note any deviation from the planned rollout arc.
Insufficient right rudder during deceleration. This is the coordination error most closely tied to aerodynamic understanding. As the airplane decelerates through the second phase, left-turning tendencies grow. Students who apply a fixed right rudder deflection at the start and do not increase it will drift into a left skid. The slip/skid indicator ball will move right (ball right, push right rudder). At minimum controllable airspeed, an uncoordinated skid dramatically increases stall speed and reduces control effectiveness, creating a potentially dangerous situation at slow speed and a high nose attitude.
Teaching Strategies for the Instructor Candidate
When introducing the chandelle, demonstrate the maneuver once at a comfortable pace while narrating each control input and the aerodynamic reason behind it. Emphasize to the student that the two phases have completely different tasks — pitch changing in phase one, pitch frozen in phase two — and use the horizon as the primary attitude reference throughout. Establish a habit of picking a reference point on the horizon at the 90-degree position before entry, so the student knows exactly when to freeze the pitch. During debriefs, focus on one error at a time: was the pitch altitude reached on time? Was it held constant? Was the rollout uniform? Was the ball centered at the 180-degree point? Isolating errors makes correction actionable rather than overwhelming.
Common Test Traps
- The chandelle is a maximum performance maneuver — the goal is minimum airspeed at rollout, not maximum altitude. Confusing the two leads to incorrect descriptions on the knowledge test.
- Pitch must be constant in the second 90 degrees. Any pitch change in phase two is an error, regardless of how close the attitude is to correct.
- Rolling out early produces excess airspeed and proves the performance was not truly maximum. Rolling out late risks a stall before wings-level.
- Right rudder demand increases progressively throughout the second phase — a single fixed input is inadequate and one of the most common practical test failures.
- ACS standards apply independently: heading, airspeed, and coordination must all be correct simultaneously at the 180-degree point for the maneuver to be satisfactory.
