Definition. V1 is the maximum speed at which a rejected takeoff can be initiated in the event of an emergency. V1 is also the minimum speed at which a pilot can continue takeoff following an engine failure.

Below V1 you still have enough runway to abort a takeoff and stop before you run off the end of the runway. After V1 there isn't enough runway left to stop so you are committed to taking off. This is very important in case of an engine failure during the takeoff run.

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.

A custom built aircraft requires a pilot license to fly in addition to an airworthiness certificate for the airplane. An ultralight does not require a pilot's license or an airworthiness certificate - generally speaking. Basically, there are five different types of materials used in building amateur-built airplanes.

V1: Also known as " Decision speed". This is the speed beyond which take-off should not be aborted. The use of full reverse-thrust is not advised eitherVr: Also known as "rotation speed". This is the speed at which the pilot begins to apply control inputs " Pitching" the aircraft nose upwards.

For every aircraft type, V1, VR and V2 are computed by Airbus on the basis of design speeds and evidence collected during the certification testing of the airplane. (fig.1) V1: Decision speed. VR: Rotation speed. V2: Take-off safety speed.
