Which statement is a canopy safety precaution?

• A. Do not use battery power to open canopy below zero degrees Fahrenheit.
• B. Do not leave canopy in an intermediate position or open/close canopy when the aircraft is in motion.
• C. Operate the canopy using a manual crank during all operations.
• D. Ignore debris around the canopy deck before operation.

Answer: (B)

Safety around canopy operation relies on controlling its position relative to the aircraft’s movement. When the aircraft is moving, wind and aerodynamic forces can push or pull the canopy, and a partially open or actively opening/closing canopy can snap, jam, or injure someone nearby. Keeping the canopy fully closed and securely locked before taxi or takeoff eliminates that risk and ensures the cockpit remains protected and the egress path is clear in an emergency.

That’s why the best safety precaution is to avoid leaving the canopy in an intermediate position and avoid opening or closing it while the aircraft is in motion. The other statements don’t address the same immediate risk: using a manual crank for all operations isn’t standard practice and can create its own hazards, and ignoring debris around the canopy deck before operation is obviously unsafe.
