The co-pilot (FO) will call out V<sub>1</sub> during take-off, the pilot will check if all engines are running and decides to continue or abort take-off. | ||

The speed at which the nose-wheel leaves (should leave) the ground. As the speed increases the yokes will be pulled at V<sub>r</sub>. It is also the speed at which the aircraft still can be stopped if there is a critical failure. The co-pilot (FO) will call out "rotate" during take off. V<sub> | The speed at which the nose-wheel leaves (should leave) the ground. As the speed increases the yokes will be pulled at V<sub>r</sub>. It is also the speed at which the aircraft still can be stopped if there is a critical failure. The co-pilot (FO) will call out "rotate" during take off. V<sub>R</sub> is very similar to V<sub>ROT</sub> and V<sub>REF</sub>. | ||
