There's an excellent schematic put out by SAS who've used the '9'for years.As the coificient(forgive the spelling)of friction decreases so should the Crosswind component.The original info for this was put out years ago by who-Douglas of course.there's an Ideal paper on this factor put out on the DC10(about83,I think)still available from MDC.Same info applies to the '9',includes good stuff like cancelling reverse if she don't go straight.re-aligning her and reversing again.Surprised you don't have this generic info..
