1. A method of operating a reverse thrust system of an engine in an aircraft, 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 based on the status signal, 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.
