What would be a typical result of a stall in flight?

A stall in flight occurs when the angle of attack of an aircraft exceeds a critical value, causing a significant loss of lift. This situation typically leads to a rapid decrease in altitude, as the wings are no longer able to generate sufficient lift to support the aircraft in flight. In addition to the loss of lift, the aircraft may start to exhibit uncommanded yaw and roll, which can lead to a spin if not properly managed.

Understanding the aerodynamic principles at play during a stall is essential for pilots, as they must recognize the signs of an impending stall and respond appropriately to recover from it. Thus, the phrase about losing lift and potentially entering a spin accurately describes the fundamental consequences of a stall, making it the correct answer.
