[ What I claim is:] [1.] A method of starting a gas turbine engine comprising the steps of:a) accelerating the gas turbine engine to a speed to provide optimum combustion air for light-off of the gas turbine engine and maintaining the gas turbine engine at this speed;b) activating the ignition source for the gas turbine engine combustor; andc) ramping up the flow of fuel to the gas turbine engine combustor at a substantially constant rate until the correct fuel-to-air ratio is achieved and light-off of the gas turbine engine occurs.
