Private Pilot License (PPL) Aerodynamics Practice Exam

In a turn, the relationship between weight and lift is grounded in the principles of aerodynamics and the physics of flight. When an aircraft is in level flight, lift must equal the weight of the aircraft to maintain altitude. However, during a turn, the dynamics change due to the need to provide an additional component of lift to counteract the centripetal force required for the aircraft to change direction.

As the weight of the aircraft increases, more lift is needed to counteract the additional gravitational force pulling the aircraft downward. Specifically, when the aircraft turns, it must not only support its weight but also generate enough lift to maintain a bank angle and perform the turn effectively. As such, an increase in weight directly translates to the requirement for increased lift to keep the aircraft level during the maneuver. Therefore, with increased weight, pilots must produce more lift, often through a combination of increasing the angle of attack (to a certain limit) and possibly adjusting airspeed.

The other options do not accurately describe this relationship. For example, stating that lift requirement decreases with more weight contradicts the basic principles of flight dynamics. Similarly, saying lift requirement is unchanged or that less weight increases lift requirement misrepresents how weight impacts lift in a turning scenario. Understanding these
