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: There is provided a data access method and system for an aircraft. Password data is obtained for use in providing access to aviation data collected by at least one data acquisition device from one or more locations in the aircraft. The password data is caused to be rendered on at least one display provided in at least one secured location of the aircraft. Subsequent to the password data being rendered on the at least one display, input data is received from at least one user device requesting access to the aviation data. The input data is compared to the password data and, when the input data matches the password data, a connection is established between the at least one user device and the at least one data acquisition device for providing the at least one user device access to the aviation data.

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 system and method for transmitting data from an aircraft, the aircraft comprising at least one engine. Aircraft input indicative of a request to enable a maintenance mode of operation of at least one engine controller for the at least one engine is received at the at least one engine controller. In response to receiving the aircraft input, a control signal comprising instructions to enable a wireless access point mode of operation of a data collection and transmission unit of the aircraft is output by the at least one engine controller to the data collection and transmission unit of the aircraft,

Abstract: A method and a system are provided for controlling a propeller-driven aircraft, the aircraft powered by at least one engine having at least one propeller associated therewith. At least one control input for the at least one engine is received at an engine controller for the at least one engine. The engine controller determines, based on the at least one control input, a setpoint for a rotational speed of the at least one propeller and outputs, to a propeller controller for the at least one propeller, a control signal comprising instructions to adjust the rotational speed of the at least one propeller to the setpoint.

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.
