V speed definitions

V speeds In aviation, V-speeds are standard terms used to define airspeeds important or useful to the operation of all aircraft.[1] These speeds are derived from data obtained by aircraft designers and manufacturers during flight testing for aircraft type-certification.

V MC Minimum control speed. V-speeds are specific airspeeds that are defined for operational reasons, such as limitations (e.g., maximum flaps extended speed – VFE) or performance requirements (e.g., best rate of climb speed – VY). In other words, V-speeds serve as critical benchmarks that guide pilots in managing the aircraft’s performance and ensuring safety.

This is the lowest speed at which the aircraft can fly before stalling while configured for landing. Copy link. V speeds explained In aviationV-speeds are standard terms used to define airspeed s important or useful to the operation of all aircraft.

Air Registration Board. VF Design flap speed. VX is the airspeed that provides the best angle of climb. Speed used during final approach with landing flap set. [1] These speeds are speed from data obtained by aircraft designers and manufacturers during flight testing for aircraft type-certification.

How Much Do Airplanes Weigh? Federal Register. VSW Speed at which onset of natural or artificial stall warning occurs. Aircraft Performance: Flying Training. ATPL ground training series. A stall occurs when the aircraft exceeds the critical angle of attack.

When this is the case, the test pilot dives to the maximum speed possible — the demonstrated flight diving speed. Using them is considered a best practice to maximize definition safety, aircraft performance, or both.[2] The actual speeds.

Delivers the greatest gain of altitude in the shortest possible horizontal distance. Here's a typical order based on key flight stages:. If they quickly pitch up, the aircraft may exceed the critical angle of attack and stall, despite being at a high airspeed.

V 1 is defined differently in different jurisdictions, and definitions change over time as aircraft regulations are amended. This is the maximum speed at which the landing gear on a retractable gear aircraft should be extended or retracted.

As altitude increases, indicated airspeed decreases while Mach remains constant. V LE Maximum landing gear extended speed. VLOF Lift-off speed. V1 is not a fixed number and is calculated before each takeoff, taking into account several factors, including aircraft weight, runway length, environmental conditions, and aircraft performance data.
