There are described herein methods and systems for providing an engine computer with a power request having been determined by an aircraft computer. The power request is sent over a communication bus and once it reaches the engine computer, the latency due to the different update rates of the engine computer and the aircraft computer are compensated for.

Digital communications between aircraft computer and engine computer

There is described herein a real-time scheme, implementable in software, hardware, or a combination thereof, to detect a resonating frequency of a structure from a sensed signal and dynamically set the center frequency of an adaptive compensator for effective attenuation of the resonating frequency.

Dynamically detecting resonating frequencies of resonating structures

A method and system of simulating one-engine-inoperative (OEI) conditions in a multi-engine single-output aircraft which involves the operation of the engines above non-zero power settings, and operating each relative to one another to simulate power loss experienced during an actual failure of at least one engine.
