True or False: The canopy defog must be off during takeoff and landing.

The statement that the canopy defog must be off during takeoff and landing is true. This requirement is in place primarily to ensure optimal visibility for the pilot during critical phases of flight. When the canopy defog is on, it can create visual distortions or reduce clarity, which could impair the pilot's ability to see the runway or other important visual references. Therefore, for safety reasons, ensuring a clear and unobstructed view during the takeoff and landing phases is essential, and pilots are trained to adhere to this guideline.

For reference, not adhering to this practice could lead to challenges in maintaining situational awareness, especially under varied weather conditions where visibility is crucial.
