Abstract:
1. A method for monitoring at least two engines in a plane, comprising: controlling and monitoring the at least two engines by engine monitoring calculators, each engine monitoring calculator of the engine monitoring calculators is assigned to monitor one engine of the at least two engines, and each engine monitoring calculator of the engine monitoring calculators are connected to all other engine monitoring calculators by a communication network; monitoring with each engine monitoring calculator, operating parameters of the one of the at least two engines it is assigned to monitor; one engine monitoring calculator for one of the at least two engines outputting on the network a first value for at least one of the operating parameters for comparison with a second value of a same operating parameter outputted by an other engine monitoring calculator for an other engine of the at least two engines, and each engine monitoring calculator outputs operating parameters to all other engine operating calculators via the network; diagnosing one of the at least two engines as operating abnormally, by determining in the engine monitoring calculators, if the first value deviates from the second value by a difference higher than a predetermined threshold; and outputting a diagnosis of an engine monitoring calculator to another engine monitoring calculator for comparison therein.
