Your question: What are the V speeds for airplanes?

What V speed is VS?

VS. — Stall speed or minimum steady flight speed at which the airplane is controllable. VS is a generic term and usually does not correspond to a specific airspeed.

What does V1 VR and V2 mean?

This is known as V1. The second speed is when the nose should be raised and the airplane is rotated into the climb attitude, known as Vr. … 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.

What is VR VX and VY?

Vx is the speed where you have the most excess force (thrust), and Vy is the speed where you have the most excess power (horsepower).

What does V stand for in aviation?

The Red Line at the top of the Yellow Arc is the Velocity (V) that you Never (n) Exceed (e). This is the Red Line of the Airspeed Indicator, and the Vne is the Maximum Speed the Aircraft should ever be operated in Smooth Air.

What are the V speeds for a Cessna 172?

N12874 C-172 Skyhawk

V-Speed MPH
Va: (Maneuvering Speed) 112MPH
Vfe: (Max flap extended speed) 100MPH
Vno: (Max structural cruising speed) 145MPH
Vne: (Never exceed speed) 182MPH

Why do pilots say heavy?

Thus, the term “heavy” (unlike light, medium and large) is included by heavy-class aircraft in radio transmissions around airports during take-off and landing, incorporated into the call sign, to warn other aircraft that they should leave additional separation to avoid this wake turbulence.

Why pilots say rotate on take off?

Pilots say rotate to indicate that the airplane has reached its rotation speed, which is the speed at which the airplane can take off safely without stalling.

At what speed does a fighter jet take off?

The speeds needed for takeoff are relative to the motion of the air (indicated airspeed). A headwind will reduce the ground speed needed for takeoff, as there is a greater flow of air over the wings. Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph).

What is VX in Cessna 172?

The Cessna 172 POH lists VX as64 KIAS; for the Cirrus SR22 it is 78KIAS, and for the Tecnam Light Sport airplane, it is 60 KIAS.

What is VSO and VS1?

VS0 means the stalling speed or the minimum steady flight speed in the landing configuration. VS1 means the stalling speed or the minimum steady flight speed obtained in a specific configuration.

What does VX mean flying?

VX is the speed at which the airplane achieves the greatest gain in altitude for a given distance over the ground. It is usually slightly less than VY, which is the greatest gain in altitude per unit of time. The specific speeds to be used for a given airplane are stated in the FAA-approved AFM/POH.
