minimum control speed


minimum control speed
The minimum IAS (indicated air speed) at which an airplane can be safely flown under all conditions. Specifically, there are three minimum control speeds as follows:
i. VMCA . The minimum speed at which an aircraft can be controlled in the air. It is defined as the minimum limiting speed above which it is possible to climb away with the bank angle not greater than 5° after the failure of the critical engine in the takeoff configuration, with the failed engine windmilling and the center of gravity at its aft limit.
ii. VMCG . The minimum speed at which an aircraft can be controlled on the ground. Above this speed, the pilot can maintain directional control of the aircraft consequent to the failure of the critical engine without applying more than 155 lb (70 kg) force.
iii. VMCL . The minimum speed at which an aircraft can be controlled in the landing configuration, while applying the maximum variation of power on the remaining engines consequent to the failure of the critical engine.
