I always thought V1 was the speed at which you were committed to flying if an engine failed, due to the inability to stop on the remaining runway if you aborted at that speed or higher. If that is indeed the case, how would Pat's comment above work? If you have an airplane that can take off within 3,500 feet, on an 11,000 foot runway - how would you calculate V1? You obviously have much more runway than is needed, and if V1 is calculated based upon the stopping distance from a given speed, then V1 would be a very high number on this runway wouldn't it? |
Straight from the FAR/AIM:
V1 means the max speed in the takeoff at which the pilot must take the first action (e.g. apply brakes, reduce thrust, deploy speed brakes) to stop the airplane within the accelerate-stop distance. V1 also means teh minimum speed in the takeoff, following a failure of the critical engine at Vef at which the pilot can continue the takeoff and achieve the required height above the takeoff surface within the takeoff distance.
