What is the consequence of a stall in flight?

A stall in flight occurs when the angle of attack exceeds the critical angle, causing a significant reduction in lift. As a result, one of the primary consequences of a stall is the potential loss of control. This is because the aircraft may experience an abrupt change in attitude and airspeed, leading to difficulty in managing the flight path and maintaining stability. Pilots must react quickly and appropriately to recover from a stall, as failure to do so can result in a dangerous situation, including a spin or further descent.

The other consequences, such as loss of altitude, may happen as the aircraft transitions out of controlled flight, but they are not the immediate consequence of a stall itself. Increased speed is not typically associated with a stall; instead, the aircraft usually experiences a loss of speed and lift. Maintenance notifications are unrelated to the real-time flying conditions and would not directly correlate with the immediate effects of an in-flight stall.
