What is the main consequence of exceeding MCRIT?

Exceeding MCRIT, or the minimum control speed in critical flight situations, primarily raises the risk of stalling and losing control of the aircraft. At speeds below MCRIT, the aircraft may not have sufficient control authority due to inadequate airflow over the wings and control surfaces, making it difficult for the pilot to make necessary adjustments. This situation can lead to a stall, which is when the aircraft can no longer generate enough lift to maintain flight. If this occurs, the pilot may experience a significant loss of control, highlighting the critical nature of adhering to MCRIT to ensure the aircraft remains controllable and safe during flight operations.
