초록

A method of deploying a ram air turbine for an aircraft only during flight that deploys the ram air turbine only when a predetermined number of aeronautical power generation contactor signals are in an engaged state, an external power generation contactor is in a disengaged state, wheels for the aircraft are in an airborne state and all of multiple primary electric buses are in a fault state that represents electric potential below a predetermined level.

청구항

1. A method of deploying a ram air turbine only during flight that comprises the steps of: changing an aeronautical power engagement signal from a negative state to a positive state when at least a predetermined number of aeronautical power generation contactor signals are in an engaged state;changing a ground operations signal from a negative state to a positive state when an external power generation contactor signal is in an engaged state or multiple ones of weight-on-wheel (WOW) signals are in a ground state;changing an airborne signal from a negativ...
