Abstract
A starting system and method for a gas turbine engine checks to determine whether ignition has occurred in a light off window. If such ignition has not occurred, a starter coupled to the gas turbine engine is deactuated to allow deceleration through the light off window while still attempting to ignite gases in the combustor. By providing an extra interval of time to achieve ignition, start reliability is enhanced.
