Minimum control speeds
Minimum control speeds (VMCs) are so-called V-speeds that are included in the limitations section of airplane flight manuals (AFM) of all multi-engine airplanes. In general, a minimum control speed is the calibrated airspeed below which directional or lateral control of an airplane (i.e. the desired heading or bank angle) on the ground (runway) or in the air can no longer be maintained by the pilot after failure of a wing-mounted engine, or while such an engine is inoperative, as long as the thrust of the opposite engine on the other wing is at the maximum (takeoff) setting. VMCs are also used by airplane design engineers for sizing the vertical tail or stabilizer and the aerodynamic flight control surfaces.Many manuals for pilots and reports by accident investigators present and use VMCs as they are defined in aviation regulations that are for design and certification of multi-engine airplanes, such as FAR 23 or FAR 25 or equivalent and not as they apply to the operational use of the airplanes by pilots. Therefore, this article intends to bridge the knowledge gap between design engineers, flight-test crews, multi-engine rated (airline) pilots, and airplane accident investigators, by explaining the minimum control speeds VMC as taught by aeronautical universities and used in airplane design and by (experimental) test pilot schools, such as the USAF Test Pilot School, the Empire Test Pilot's School and the US Naval Test Pilot School.
