US Patent 11933248 Reverse thrust system and method

A method of operating a reverse thrust system of an aircraft engine, the method comprising: receiving a status signal indicative that the aircraft is on-ground or in-flight; and upon detecting that the aircraft is on-ground, overriding a protection module such that the reverse thrust system is operable regardless of the protection module being in an active state or in a disabled state, the protection module causing, absent the overriding, the reverse thrust system to be inoperable when in the active state. An aircraft comprising: an engine including a reverse thrust system; a thrust control input device configured for generating an input signal indicative of a reverse thrust demand; at least one sensor configured for generating at least one status signal indicative of the aircraft being in-flight or on-ground; and a control system electronically connected with the at least one sensor, the thrust control input device and the reverse thrust system.
