Description
Velocity minimum control is a V speed. Velocity minimum control has two speeds, VMCA for in the air and VMCG for on the ground. Generally, it can be defined as the slowest speed an aircraft can be controlled at when the critical engine has failed. You should still be able to fly straight with using an angle of bank less than or equal to five degrees.

In order for aircraft to be certified for velocity minimum control at takeoff, the following conditions are used. There is a standard atmosphere, the center of gravity is farthest aft, the aircraft is out of ground effect, the critical engine has failed, the aircraft is banked no more than five degrees towards the critical engine, at the time of engine failure there is maximum power to each engine, the aircraft is trimmed properly for takeoff, on light aircraft the cowl flaps are open, the landing gear is retracted, the failed critical engine is wind milling, the rudder input must not be more than 150 pounds, and the aircraft must hold a heading of within 20 degrees.

VMCA
The velocity minimum control speed in the air is represented on the airspeed indicator by a red line on the airspeed indicator.

VMCG
Velocity minimum control ground or VMCG is the minimum control indicated airspeed for when the aircraft is on the ground usually on the takeoff roll. Light aircraft do not have a published VMCG. It is assumed that the front wheel is no longer on the runway but the main wheels are.

Regulations
VMC certification is regulated in the United States under Federal Aviation Regulations Part 25 Section 149 and Canadian Aviation Regulations Part 5 under chapter 525:149 of the airworthiness manual.
