Abstract: There are described methods and systems for operating an aircraft having two or more engines. One method comprises operating the two or more engines of the aircraft in an asymmetric operating regime, wherein a first of the engines is in an active mode to provide motive power to the aircraft and a second of the engines is in a standby mode to provide substantially no motive power to the aircraft; governing the first engine in the active mode using a first governing logic; and governing the second engine in the standby mode using a second governing logic, the second governing logic based on a target compressor speed and variable geometry mechanism (VGM) settings that are adjusted using trim values dependent on at least one parameter of the second engine in the standby mode.

Abstract: A communication system and a method for transmitting data from an aircraft, the aircraft comprising at least one engine. A data collection and transmission unit is configured to collect and transmit data received from one or more locations in the aircraft, the data collection and transmission unit comprising at least one radio transmitter. At least one engine controller for the at least one engine is communicatively coupled to the data collection and transmission unit and configured to transmit, while the aircraft is airborne, engine data to the data collection and transmission unit, and, responsive to determining that the aircraft is on ground, cause the at least one radio transmitter to activate for transmitting the engine data from the data collection and transmission unit to at least one ground equipment.

Abstract: A data transmission system and method for an engine of an aircraft. Engine fault data indicative of at least one fault condition of the engine is obtained at a computing device provided on-board the aircraft. Sensor data associated with the at least one fault condition is retrieved based on the engine fault data. The engine fault data and the sensor data are transmitted, through a wireless connection, to an electronic device external to the aircraft.
