An operator may adopt any other definition outlined in the aircraft flight manual (AFM) of TC type-approved aircraft as long as such definition does not compromise operational safety of the aircraft. 8.Using them is considered a best practice to maximize aviation safety, aircraft performance or both.They are expressed by the aircrafts indicated airspeed (and not by, for example, the ground speed ), so that pilots may use them directly, without having to apply correction factors, as aircraft instruments also show indicated airspeed.
The lower ends of the green arc and the white arc are the stalling speed with wing flaps retracted, and stalling speed with wing flaps fully extended, respectively. ![]() The yellow range is the range in which the aircraft may be operated in smooth air, and then only with caution to avoid abrupt control movement, and the red line is the V NE, the never exceed speed. In the United States, these are defined in title 14 of the United States Code of Federal Regulations, known as the Federal Aviation Regulations (FARs). In Canada, the regulatory body, Transport Canada, defines 26 commonly used V-speeds in their Aeronautical Information Manual. V-speed definitions in FAR 23, 25 and equivalent are for designing and certification of airplanes, not for their operational use. ![]() Some of these constraints have been omitted to simplify the description. The speed at which the aircraft may safely be climbed with one engine inoperative. The all engines operating take-off climb speed used to the point where acceleration to flap retraction speed is initiated. This is the speed above which it is unwise to make full application of any single flight control (or pull to the stops) as it may generate a force greater than the aircrafts structural limitations. If both V S0 and V S1g are available, the higher resulting V at shall be applied. Also called approach speed. Denotes critical engine failure speed as the speed during takeoff where the same distance would be required to either continue the takeoff or abort to a stop. This is the maximum speed at which a retractable gear aircraft should be flown with the landing gear extended. This is the maximum speed at which the landing gear on a retractable gear aircraft should be extended or retracted. The minimum speed at which the aircraft is still controllable with the critical engine inoperative. Like the stall speed, there are several important variables that are used in this determination. Refer to the minimum control speed article for a thorough explanation. V MC is sometimes further refined into more discrete V-speeds e.g. V MCA,V MCG. The minimum speed that the aircraft is still controllable with the critical engine inoperative 18 while the aircraft is airborne. The minimum speed that the aircraft is still controllable with the critical engine inoperative 18 while the aircraft is on the ground. Refusal speed is the maximum speed during takeoff from which the air vehicle can stop within the available remaining runway length for a specified altitude, weight, and configuration. Incorrectly, or as an abbreviation, some documentation refers to V ref andor V rot speeds as V r. ![]() It is the speed above which the takeoff will continue even if an engine fails or another problem occurs, such as a blown tire. The speed will vary among aircraft types and varies according to factors such as aircraft weight, runway length, wing flap setting, engine thrust used and runway surface contamination, thus it must be determined by the pilot before takeoff. Aborting a takeoff after V 1 is strongly discouraged because the aircraft will by definition not be able to stop before the end of the runway, thus suffering a runway overrun. V 1 also means the minimum speed in the takeoff, following a failure of the critical engine at V EF, at which the pilot can continue the takeoff and achieve the required height above the takeoff surface within the takeoff distance. An operator may adopt any other definition outlined in the aircraft flight manual (AFM) of TC type-approved aircraft as long as such definition does not compromise operational safety of the aircraft.
