There is provided a software update method and system for an aircraft. Software data is obtained at a computing device mounted to the aircraft, the software data comprising a software loader and one or more software files containing an update to a software configuration of at least one target device mounted to the aircraft and communicatively coupled to the computing device. The software loader is executed at the computing device to install the one or more software files into the at least one target device and thereby modify the software configuration of the at least one target device according to the update.

System and method for software update in aircraft

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.

System and method for transmission of engine fault data

Systems, methods, and stored coded instruction sets for reducing the amount of data captured, i.e., retained, by a computerized system, such as an aircraft flight control or monitoring system. Such systems can, for example, be used in monitoring and/or controlling the operation of one or more aircraft engines, flight controls, or other aircraft systems, in order to optimize storage required for collected data, and/or to reduce or otherwise control the time required to off-load captured data to another computer system, such as a land-based analysis system. The amount of data collected, e.g., captured or retained in memory, may be reduced by discarding data points that are within a specified tolerance of, for example, a previously observed or expected value in a manner which assists with preserving the accuracy and precision of the original measured data.

Method and system for generating a data set

An aircraft data acquisition and/or transmission system comprises a memory having stored therein a first state machine configuration comprising a first allocation between a plurality of transition criteria objects stored in a first area of the memory and a plurality of state objects stored in a second area of the memory separate from the first area. A processor is coupled to the memory and at least one application executable by the processor causes a first data acquisition and/or transmission behavior in the aircraft by running the first state machine configuration, receives a second state machine configuration comprising a second allocation between the plurality of transition criteria objects and the plurality of state objects, and causes a second data acquisition and/or transmission behavior in the aircraft by running the second state machine configuration.
