Abstract:
1. A method of engine starting in a gas turbine engine, comprising: measuring at least one parameter of a current environment in which the engine is to be started; searching in a database for at least one parameter regarding an engine starting process in a previous environment having a parameter similar in value to the measured parameter; determining at least one new parameter for an engine starting process in the current environment, based on information relating to the parameter searched in the database; starting the engine using the new parameter and completing a current engine starting process; measuring a light-off time of the engine during the current engine starting process; and comparing the measured light-off time with a previous light-off time stored in the database and associated with the previous environment, and re-writing the database with the new parameter and the measured light-off time when the measured light-off time is shorter than the previous light-off time stored in the database.
