What is the FAA definition of V1?
What is the FAA definition of V1? V1. maximum 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.
Why does a plane have to take off after V1?
Until V1 is reached, the pilot generally keeps their hand on the throttle in case they need to abort for any reason. After V1, it's all about ensuring the aircraft lifts off with no issue. After the pilot removes their hand from the throttle, they can start to lift the plane's nose up.
Why do pilots say V1 rotate?
During the takeoff roll, the pilot monitoring the displays (PM) will call out the two important speeds: V1 and rotate. This indicates to the pilot flying the aircraft (PF) when they are beyond the safe stopping speed and when to rotate the aircraft into the air.
