What is the recommended entry speed in chandelles and lazy eight?

• A. 95 knots
• B. 149 knots
• C. 70-80 knots
• D. 55 knots

Answer: (A)

The speed chosen for starting chandelles and lazy eights is all about energy management and having enough control authority to complete the maneuver safely. You want enough airspeed to maintain lift and a clean climb without stalling, but not so much that you can’t execute the required pitch and bank changes smoothly or overshoot the maneuver. About 95 knots gives that sweet balance. It sits well above stall speed, so you have a comfortable margin to hold a steady climb and to coordinate the turns, yet it isn’t so fast that you’re chasing altitude or lose precise control during the 180-degree portion of the maneuver. If you start much faster, you gain energy but you sacrifice maneuverability and risk overshooting or stressing the aircraft during the turns. If you start much slower, stall risk and insufficient energy to complete the required energy exchange become real concerns. So, 95 knots is the practical entry speed that provides enough performance margin and control to perform chandelles and lazy eights safely and predictably.
