Which term denotes the speed at which engine failure is assumed to occur?

Explanation:
Engine failure speed is the speed used in takeoff performance calculations at which an engine failure is assumed to occur. This allows evaluating whether the airplane can continue the takeoff and meet the required climb with one engine inoperative. It sits in the takeoff envelope between the abort/continue decision point and the safe-climb speed with one engine out. V1 is the decision speed for aborting or continuing, V2 is the minimum safe climb speed with one engine out, and Vref is a landing reference speed. So the term that denotes the speed at which engine failure is assumed to occur is engine failure speed (Vef).
