System and method for monitoring temperature of a gas turbine engine

A system for monitoring a temperature of a gas turbine engine, the system comprising:

• a processing unit;
• and
• a non-transitory computer-readable medium having stored thereon program instructions executable by the processing unit for:
• obtaining individual sensor readings from functioning temperature sensors of a sensor array, where a number of the functioning temperature sensors is less than a total number of temperature sensors in the sensor array;
• applying correction factors to the individual sensor readings based on deviations of the individual sensor readings from a total average temperature of all the temperature sensors in the array, to obtain corrected individual sensor readings;
• and
• determining a corrected total average temperature as a sum of the corrected individual sensor readings divided by the number of functioning temperature sensors.
