- A method for determining an astimated operating parameter (72) for a gas turbine (10) including the steps of: determining an astimated operating parameter (72) using an algorithm (74) have an input from a sensor (78), wherein the algorithm includes a trim factor (K); determining a first trim factor (K) based on a comparison of the first estimated operating parameter (72) and the output (76) of the sensor when a condition of the sensor is in a first mode (82), and during a subsequent determination (84) of the estimated operating parameter, applying the first trim factor (K) to subsequently determine the estimated operating condition if the condition of second sensor is in a second mode.
