Final answer:
An increase in weight increases maneuvering speed, and a decrease in weight decreases maneuvering speed, due to the relationship between weight, lift, and angle of attack during a turn.
Step-by-step explanation:
Discussing the effect on maneuvering speed of an increase or decrease in weight, maneuvering speed is affected by weight changes: An increase in weight increases maneuvering speed (A), and conversely, a decrease in weight decreases maneuvering speed (B). This is because maneuvering speed, often referred to as cornering speed in aviation, is the maximum speed at which an aircraft can be safely flown while making a turn without exceeding the maximum design load factor. The maneuvering speed increases with the aircraft's weight because a heavier aircraft requires more lift, and thus more angle of attack at a given airspeed, to maintain altitude during a turn.
