Abstract
Control logic, and a method implemented by the control logic, compensates for mismatched inter turbine temperatures between two gas turbine engines and displays a biased inter turbine temperature (ITT) reading to the pilot without jeopardizing the need to be properly informed of the health of all engines and the relationship engine temperature compared to the maximum allowed temperature. A temperature compensation value is added to the lower inter turbine temperature to thereby increase the ITT to a value that is substantially equal to the higher ITT value. As a result, any potential nuisance or distraction that the flight crew may experience from displaying the mismatch is eliminated.
