VMCG

The minimum control speed on the ground. If an engine fails during the takeoff run, this is the minimum speed at which the direction can be maintained without applying more than 155 lb (70 kg) pedal force. Some aircraft with good nose-wheel steering can handle the situation at any speed, provided the nose-wheel is in contact with the ground. It is a function of altitude and temperature. Its value should be equal to or less than V1 or the decision speed.
