Which of the following is NOT a basic flight maneuver to be demonstrated during a flight test?

High-speed turns are not considered a basic flight maneuver typically demonstrated during a flight test. The focus of flight tests is generally on fundamental skills essential for safe flying and effective aircraft handling.

Stalls, climbs, and descent maneuvers are critical for evaluating a pilot's ability to manage the aircraft under various flying conditions. Stalls help assess a pilot's understanding of critical airspeeds and recovery techniques. Climbs are essential for demonstrating the ability to gain altitude efficiently, while descent maneuvers are crucial for safety when approaching landing.

In contrast, high-speed turns are not part of the essential maneuvers because they are less relevant to the primary objectives of a flight test. Such maneuvers often involve greater risk and may not reflect the common conditions a pilot would typically encounter in normal flight operations.
