Knertius,
It will depend on which Canadian Bus you strap to your Bum
100,200 or 300.
You should find a placard in a 1 or 200, on the F/O's side normally, regarding the assumed weight required for a F15 TKOFF with YD on. Otherwise it should be YD off til L.OFF.
As I said earlier, its been a few years for me but it was a happening thing back then.
Cheers,
Con
