The VC of an aircraft is the V speed which refers to the velocity of cruising. VC is within the green arc on many airspeed indicators. This speed varies is different for each aircraft model. VC may stand for: vehicular cycling Venture capital Vice-county Victoria Cross Viet Cong Vinyl chloride Virginia Central Railway (AAR reporting mark VC) virtual circuit Visual C++ Volkov Commander (file manager) Saint Vincent and the Grenadines: ISO country code This is a disambiguation page — a navigational aid which lists pages...

An Airbus A380, currently the worlds largest airliner An aircraft is any vehicle or craft capable of atmospheric flight. ... V speeds are speeds that define certain performance and limiting characteristics of an aircraft. ... The velocity of an object is simply its speed in a particular direction. ... Airspeed Indicator The airspeed indicator is an instrument used in an aircraft to display the crafts airspeed, typically in knots, to the pilot. ...


VC is also called the design cruising speed or the optimum cruise speed – the latter being the speed giving the most velocity (i.e greatest distance/time) from a litre of fuel, usually utilising 75% power at Maximum Take-Off Weight (MTOW) and about 1.3 times the maximum lift-to-drag ratio (L/D) speed – Vbr above. The speed and power required decrease as the aircraft weight decreases from MTOW. In aviation, the Maximum Take-Off Weight (or MTOW) is the maximum weight with which an aircraft is allowed to try to achieve flight. ... In aerodynamics, the lift-to-drag ratio, or L/D ratio (ell-over-dee, as opposed to ell-dee), is the amount of lift generated by a wing, compared to the drag it creates by moving through the air. ...


For normal category aircraft FAR Part 23 specifies a minimum design cruising speed (in knots) based on the wing loading of (weight in pounds divided by wing area in square feet). For the utility category, the minimum design cruising speed is . Many ultralight aeroplanes are unable to comply with the FAR part 23 requirement for a minimum design cruising speed. It has been suggested that Temporary Flight Restriction be merged into this article or section. ... In aerodynamics, wing loading is the loaded weight of the aircraft divided by the area of the wing. ...
