1. A method of starting a gas turbine engine, 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 a 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.
