Side Slipping any jet
If memory serves me correctlly, the side slip manz is the correct proc. for landing ANY AIRPLANE in a cross wind. In a med. to heavy jet, based on my exp., 5500 hrs. in such, a side slip should only be initiated during the flare/roundout during landing. There should be no need to set up one during approach if you are tracking the centerline properly with crab angle. And by all means NEVER set up a forward slip in ANY jet as engines 1 thru 4 will not agree and either compressor stall or quit all together. Hope that helps.
