All helicopters incorporate a one-way clutch system that allows the rotor blades to continue to rotate under the effects of inertia and autogiro-type flight in the event of engine failure. ... the flow of the airstream through the helicopter rotor disk is reversed. The force of gravity continues the operation of the rotor blade, thereby reducing the rate of descent and allowing a successful emergency landing. Because of the time required to effect this change and the necessity for other flight maneuvers, these characteristics led to the development of a restricted area of operations of the helicopter known as the deadman's curve, bounding that area of height and speed in which the helicopter should not be operated. 1, record 2, English, - deadman%27s%20curve

If an engine actually fails prior to this selected speed, the pilot brakes to a stop.

Équivalent proposé par André Sénécal, traducteur à la Technique centrale. On parle de "voyant", car le dispositif en question ne saurait être autre chose qu'une lampe-témoin ou un voyant. Le terme "switch" n’ a rien d’un interrupteur : il signifie tout simplement que lorsque le régime va baisser sous un point critique, un contact va s’établir, de façon que l'opérateur puisse en être averti. Quant au terme "speed", il est traduit ici par "régime"(qui s’exprime en tours/minute et s’applique à un moteur), plutôt que par "vitesse"(qui s’exprime par exemple en m/h et s’applique à des corps ou véhicules en mouvement) ou par "rotation"(qui s’exprime également en tours/minute, mais s’applique à des arbres mécaniques). Le terme "zero" en anglais ne signifie pas ici que le régime est nul, mais qu'il passe en dessous d’un niveau déterminé. 1, record 8, French, - voyant%20d%27avertissement%20de%20bas%20r%C3%A9gime
