Vmca
Minimum Control Speed Air
| Question | Answer |
|---|---|
| ir minimum control speed, Vmca (89 KIAS), is the minimum controllable speed in the | take-off configuration out of ground effect with one engine in operation and the remaining engine at take-off rated thrust. |
| Vmca is determined at the most critical combination of asymmetric thrust, light weight, and aft center of gravity. | The speed is established with the aircraft trimmed for takeoff, |
| 5 degrees angle of bank into the operating engine and no more than 180 pounds of rudder control force by the pilot with the rudder boost system operating | Vmca is always less than take-off speed and is not considered in takeoff planning. |
