Incorrectly, or as an abbreviation, some documentation refers to V ref and/or V rot speeds as "V r." [29] V S: Stall speed or minimum steady flight speed for which the aircraft is still controllable. [7] [8] [9] V S 0: Stall speed or minimum flight speed in landing configuration. [7] [8] [9] V S 1
As a result, nautical miles and knots are convenient units to use when navigating an aircraft or ship. On a standard nautical chart using Mercator projection, the horizontal (East–West) scale varies with latitude. On a chart of the North Atlantic, the scale varies by a factor of two from Florida to Greenland. A single graphic scale, of the ...

At a glance, the pilot can determine a recommended speed (V speeds) or if speed adjustments are needed. Single and multi-engine aircraft have common markings. For instance, the green arc indicates the normal operating range of the aircraft, from V S1 to V NO. The white arc indicates the flap operating range, V SO to V FE, used for approaches ...
The list of hull classifications comprises an alphabetical list of the hull classification symbols used by the United States Navy to identify the type of a ship.. The combination of symbol and hull number identify a modern Navy ship uniquely.
The forward driving force (F R) component contributes to boat velocity (V B), which is, itself, a determinant of apparent wind velocity. Absent lateral reactive forces to F T from a keel (in water), a skate runner (on ice) or a wheel (on land), a craft would only be able to move downwind and the sail would not be able to develop lift.
Supersonic aircraft, like the Concorde and military fighters, use the Machmeter as the main speed instrument with the exception of take-offs and landings. Some aircraft also have a taxi speed indicator for use on the ground. Since the IAS often starts at around 74–93 km/h (40–50 kn) (on jet airliners), pilots may need extra help while ...
Airspeed is commonly given in knots (kn). Since 2010, the International Civil Aviation Organization (ICAO) recommends using kilometers per hour (km/h) for airspeed (and meters per second for wind speed on runways), but allows using the de facto standard of knots, and has no set date on when to stop.
