decision speed
Definição1
The maximum speed during take-off at which the pilot must take the first action (e.g. apply brakes, reduce thrust, deploy speed brakes) to stop the aeroplane within the accelerate-stop distance available. It is also the minimum speed during take-off, following the failure of the critical engine at VEF, at which the pilot can continue the take-off and achieve screen height within the take-off distance available. V1 must not be less than VMCG, not greater than VR and not greater than VMBE.

Acronym: V1
Contexto
The decision speed is not a fixed speed for any aeroplane, but can be selected by the pilot within limits to suit the accelerate-stop and take-off distance available, aeroplane take-off mass, runway characteristics and ambient atmospheric conditions at the aerodrome. Normally, a higher decision speed is selected as the accelerate-stop distance available increases.
