Commercial Ground – Basic Aerodynamics Practice Test

The correct choice highlights that the sensation of being pressed into the seat is a clear indicator of the load factor experienced by a pilot. Load factor is defined as the ratio of lift to weight, which changes during maneuvers such as turns, climbs, and descents. When an aircraft experiences increased load factor, for example, during a steep turn, pilots physically feel a greater force acting on their bodies, which can make them feel heavier or more firmly pressed into their seats. This feeling corresponds directly to the increased g-forces experienced during those maneuvers, providing a tangible way for pilots to gauge the changing load factor without needing specialized instruments.

The airspeed indicator primarily provides information about the aircraft's speed relative to the surrounding air, but it does not directly indicate load factor. While the angle of bank contributes to the overall load factor, it doesn't provide a complete picture on its own, as the load factor can also be influenced by speed and other factors. Similarly, control pressure applied by the pilot pertains more to aircraft handling and response rather than directly indicating load factor, which is primarily felt in terms of the forces acting on the pilot's body.
