What are the V speeds for airplanes?

Regulatory V-speeds

V – speed designator Description
V FE Maximum flap extended speed.
V FTO Final takeoff speed.
V H Maximum speed in level flight at maximum continuous power.
V LE Maximum landing gear extended speed. This is the maximum speed at which a retractable gear aircraft should be flown with the landing gear extended.

What is V2 in aviation?

V2: Takeoff Safety Speed. V2 is the minimum speed that needs to be maintained up to acceleration altitude, in the event of an engine failure after V1. Flight at V2 ensures that the minimum required climb gradient is achieved, and that the aircraft is controllable.

What does VS stand for?

vs is often an abbreviation for versus.

Why are they called V speeds?

The “ V ” is from the French word ‘Vitesse’ which means ‘ speed ‘ or ‘rate’. Important aviation Airspeeds are identified and defined using standard terms. Scientists and Engineers refer to Airspeeds as ‘ V ‘ Speeds. Commonly, people think in terms of “ Velocity ”, and it is a nice memory aid, as “ Velocity ” begins with “ V ”.

What is V1 and V2 on takeoff?

A: V1 is the speed by which time the decision to continue flight if an engine fails has been made. It can be said that V1 is the “commit to fly” speed. V2 is the speed at which the airplane will climb in the event of an engine failure. It is known as the takeoff safety speed.
