Claim 14:
15. A system for detecting a functional failure in a power gearbox, in an aircraft gas turbine engine comprising:
at least one sensor measuring operational data in the gas turbine engine of at least two operational parameters dependent on at least one chosen from power generation and power consumption of the gas turbine engine and the power gearbox,
a computing device including a processor and configured for obtaining analyzed operational data comprising at least one chosen from time data, angular data of a rotation, frequency data and phase data from the measured operational data and for using the analyzed operational data in a comparison with stored baseline operational data to determine deviation data from the baseline operational data,
a trend computing device including a processor and configured for determining at least two time dependent trend data analyses from the deviation data, and
at least one chosen from a generation device and a protocol generation device for controlling at least one chosen from the power gearbox and the gas turbine engine based on the at least two time dependent trend data analyses.
