Method of starting a gas turbine engine

A system for starting a gas turbine engine, comprising:

• a starting system configured to start the gas turbine engine;
• processing circuitry coupled to the gas turbine engine and the starting system, the processing circuitry configured to execute instructions comprising:
• selecting a baseline starting procedure of the gas turbine engine based on environmental data for an environment around the gas turbine engine;
• receiving condition information for the gas turbine engine and/or for the starting system of the gas turbine engine, the condition information comprising at least one of:
• health information for the gas turbine engine and/or the starting system;
• maintenance information for the gas turbine engine and/or the starting system;
• and
• operation information relating to an expected future usage of the gas turbine engine;
• determining a predicted degradation profile for the gas turbine engine and/or the starting system based on the condition information;
• determining a starting procedure of the gas turbine engine by adapting the baseline starting procedure based on the predicted degradation profile;
• and
• controlling the gas turbine engine and/or the starting system according to the determined starting procedure.
