    • PROBLEM TO BE SOLVED: To provide a method and an apparatus for performing a backup control routine in consideration of a pressure change probably caused in an ambient environment of a gas turbine. SOLUTION: A method of controlling the operation of the gas turbine (10) includes a step of determining a first temperature associated with a portion of the gas turbine (10) during the operation of the gas turbine (10), and a step of sensing an operation parameter of the gas turbine (10) during the operation of the gas turbine (10). Ambient pressure in an ambient environment of the gas turbine (10) is also sensed and the operational parameter is corrected using the ambient pressure sensed in the ambient environment of the gas turbine (10) to establish a corrected operational parameter. A threshold temperature is determined based at least in part on the corrected operational parameter, and a backup routine is initiated to limit the operation of the gas turbine (10) when the temperature associated with the gas turbine (10) is higher than or equal to the threshold temperature.
