The minimum control speed (V MC) of a multi-engine aircraft (specifically an airplane) is a V-speed that specifies the calibrated airspeed below which directional or lateral control of the aircraft can no longer be maintained, after the failure of one or more engines.
Used instead of V R (in discussions of the takeoff performance of military aircraft) to denote rotation speed in conjunction with the term V ref (refusal speed). [19] V Ref: Landing reference speed or threshold crossing speed. [7] [8] [9] Must be at least 1.3 V S 0. Must be at least V MC for reciprocating-engine aircraft, or 1.05 V MC for ...
The ASI in multi-engine aircraft includes two additional radial markings, one red and one blue, associated with potential engine failure. The radial red line near the bottom of green arc indicates V mc, the minimum indicated airspeed at which the aircraft can be controlled with the critical engine inoperative.

Thus, for example, VP-1 is the designator for Patrol Squadron One, where the "V" stands for Heavier-than-Air and the class letter "P" stands for Patrol, while ZP-1 is the designator for Airship Patrol Squadron One, with the "Z" indicating Lighter-than-Air. Two or more class letters may follow the "V".
VFR / VMC visibility requirements in the US. In aviation, visual meteorological conditions (VMC) is an aviation flight category in which visual flight rules (VFR) flight is permitted—that is, conditions in which pilots have sufficient visibility to fly the aircraft maintaining visual separation from terrain and other aircraft.
The Extended-range Twin-engine Operations Performance Standards (ETOPS) (/ iː ˈ t ɒ p s /) are safety standards set by the International Civil Aviation Organization (ICAO) for twin-engine commercial passenger aircraft operations.
