Full power was always used in the Vulcan for take-off; a 4-eng go-around normally required 80% thrust; a 2-eng go-around required 93%. In a 200-ser aircraft anything more than 93% would cause the howl, particularly it the throttles were opened briskly at low speed....
300-ser aircraft were de-rated until the South Atlantic campaign, so didn't howl. The 'cruise' limit setting was then the same as the 'take-off' limit setting for 200-ser aircraft and 300-ser were always flown in 'cruise'. But those who had flown them years earlier when full power was available advised that the howl they made would shake Lincoln cathedral!
Anyway, '655 is now back on the pan with fully serviceable brakes and steering. At present there is no suggestion that there won't be any future taxy runs.
