V1 and v2 are used on all large airplanes. V1 is decision speed, that's where you decide if it's safe to take off or you abort the take off instead as there is enough runway left to stop. V2 is the speed when you rotate to take off because at that speed the airplane is going fast enought to get off the ground.and at that point there is no return, you must take off. There isn't enough runway to stop.

damn that cockpit is like a spaceship

V2 was only used on concorde in commercial planes. V1 is the usual takeoff speed for subsonic planes.
-
@Chrisy299 V1 - Past safe abort takeoff limit
V2 - Minimum takeoff speed reached
Rotate - Point nose up to start climbing.

@Chrisy299 Rotate is also known as Vr. :D
-
the frensh copilot speking is bullshit
-
there is something called Vr which is Rotation speed, the speed at which the aircraft starts to rotate and then climb to another Vx or Vy or V# depends on the aircraft checklist or type of take off

@drpittbull you must have me confused with someone else or you didnt read my profile.....the last "small" airplane I flew was a Gulfstream 4.......V2 is passed no later than 35ft above the runway on take-off. that is a certification requirement. So, once again, unless an engine fails we dont "hold" v2.....99% of the time we're passed V2 about the time the tires leave the pavement. When i used to fly the 747 many times V2 would come and were still in the rotation.

@beergut111 I appreciate the answer, but you obviously mean different type of aircraft. from your profile I could see that you fly or flown small types of aircraft, where I was basing my information on a B747-400 that follows such a procedure. I gave it as an example since we are talking about Concorde. Smaller aircraft or the ones with bigger velocity potential would ofcourse use different procedures as they would probably reach V2 much faster!
any questions?
What do they mean when they say V2 ?

These are the speed of save climb.
The first the copilot had to say is when the airspeed is increasing,the V1 (about 150 knots)-after that he had to start because of speed and runway length.
Then comes the rotate-speed about 190 knots and then V2 (about 210 knots) for save climb.

Ah ok so if they were rotating at 190 knots it would be V2 =).
LiiV3LoNDoNLiiF3 2 years ago
No. Rotating is about 190 and V2 after rotating about 210/220 knots as save climbing.

@Chrisy299 And they can't abort take-off when they've passed V1, officially though.
I've recently seen a plane having a RTO passed V1.

@Flystand The thing is that the tanks of concorde at takeoff are completely full and the airplane does not go into the air at less than 190 knots.
