An apparatus for powering an aircraft by generating power from a pressure spool (26,28) of a turbine engine (10) includes a speed range reduction assembly (74,740) that reduces the higher speed ranges of a low pressure spool (28) to lower speed ranges within the tolerances of the same DC or VF generators (58,580) used with the high pressure spool (26).
