Claim 1:
2. The method according to claim 1, wherein at least one chosen from the at least two operational parameters and a parameter of the baseline operational data is:
a torque at a shaft,
a torque at the power gearbox,
a tangential torque at the power gearbox,
a rotational speed of the shaft,
a rotational speed of at least one chosen from an input side and an output side of the power gearbox,
a power loss over the input side and output side of the power gearbox,
a speed of the aircraft,
vibrational data at the power gearbox,
a fuel intake of the gas turbine engine,
a temperature, in at least one chosen from a core of the gas turbine engine and an exit of a combustion chamber,
a temperature in at least one chosen from a feed oil temperature and a scavenge oil temperature of the power gearbox,
at least one chosen from a position and a movement of a variable guide vane in the gas turbine engine,
a pressure in the gas turbine engine, or
a deviation from a nominal value of at least one of the above parameters.
