We claim: 1. A method of providing aircraft power, the method comprising the steps of: driving a plurality of generators via an aircraft engine spool such that each generator provides AC power to a respective AC bus; driving at least one generator via a different engine spool to selectively provide additional AC power to each respective AC bus; and controlling the at least one generator to selectively synchronize the additional AC power generated via the at least one generator with the AC power generated via the plurality of generators. 2. The method...
