AIRCRAFT TAKE-OFF SPEEDS (V1,V2,Vr).

As the aircraft is ready to take-off over the ground ,there are different command speed are given to a pilot .
So in this post i will discuss with you what are different take-off speed ?


Whether it is a small double engine Cessna or a Jumbo jet A380, the definition of speed is the same for all types of planes.  These speeds are calculated prior to a take-off in accordance with aircraft weight, environmental factors etc.  We want to introduce the basic information about V1, Vr/Rotate and V2 speeds to you.

V — From the French word vitesse, meaning “speed.”

v1 is defined as the speed beyond which the take-off should no longer be aborted .that means in case where an airplane experience any trouble with its parts (eg: engine failure)  before reaching v1 speed ,the pilot is asked to abort/halt the plane ,and take the necessary action required to aircraft .otherwise  the pilot is asked to continue with the same speed .



vr/Rotate is defined as the speed at which the pilot begins to apply control inputs to make the aircraft nose to pitch-up,after which it leaves the ground.or in other words we can say /memorize is the rotate speed is the point where the nose leaves the ground and vortexes are created at the wing tips which rotate the behind the aircraft.moreover,it is the speed where main gear leaves the ground.and aircraft attains vlof-lift off speed.


v2 is the speed at which the aircraft may safely be climbed with one engine failure.this speed is also called as "take-off safety speed".If the engine failure takes place at this speed.the pilot is requested to continue its speed,and with the help of control surface asked to stabilize and land it to nearest airport.




like so there are different speed
 VABE Maximum speed for airbrake extension.
VABO — Maximum speed for airbrake operation.

THANK YOU .
edits,correction,and suggestion are most welcomed.
