Is it permissible to perform motoring with the canopy open?

Performing motoring with the canopy open is not recommended due to several safety considerations. When the canopy is open, there is a heightened risk of debris entering the cockpit, which could cause injury to the pilot or compromise the operation of the aircraft's controls. Additionally, the open canopy affects the aerodynamic characteristics of the aircraft, potentially leading to instability or unwanted movements during the motoring process.

In a training or operational environment, maintaining proper safety protocols is crucial. Keeping the canopy closed ensures that the cockpit remains a controlled environment, minimizing distractions and enhancing the pilot's ability to focus on engine operations, systems checks, and other critical tasks. Therefore, recommending not to perform motoring with the canopy open aligns with best practices for ensuring flight safety and the integrity of the aircraft.
