RB211 spool times
This may seem a little off the beaten track, but does anyone have any info regarding spool times for the RB211 on the 757? I had flown a ship that had one engine lagging behind the other on spool up and down (about 40 % and beyond they synced up). So much so that during the flare using normal retardation process, the plane yawed at about 10 feet, it was easily countered, but my question is what about during a CAT3 Autoland ? Obviously the rudder will compensate, but would it put it out of the "normal" parameters for a CAT3 and hence initiate a Go-Around ? If there are specific limits for times for the engines I would appreciate some insight, so I will have some ammunition the next time this happens. I asked the maintenance people at my airline and was met by mostly blank looks and shrugged shoulders.(No offence to MX people in general though).
