 US Patent 11987375 System and method for operating engines of an aircraft in an asymmetric operating regime

Article

Patent abstract

Methods and systems for operating an aircraft having two or more engines are described. The method comprises receiving an engine availability confirmation when a set of engine parameters meet engine operating conditions for an asymmetric operating regime, receiving an aircraft availability confirmation when a set of aircraft parameters meet aircraft operating conditions for the asymmetric operating regime, outputting an availability message to a cockpit of the aircraft in response to receiving the engine availability confirmation and the aircraft availability confirmation, receiving a pilot-initiated request to operate the engine in the asymmetric operating regime, and commanding the engines to operate in the asymmetric operating regime in response to the pilot-initiated request.
