wet, x-wind operations
The only control that will keep the a/c straight in a x-wind, especially on a wet runway is the rudder. Forget about nose wheel steering, until very late in the proceedings.
Reverse idle? Forget it. Qantas tried that (reinventing the wheel) and came to grief.
If you want the stopping power, engage full reverse ASAP, or instruct the a/c computers to do so. Anything less will increase the chances of an overrun. Yes I am aware the reverse is not factored in the landing calculations, however we need these things on our side, especially if we are not in the "slot" and begin "burning up concrete" at an alarming rate.
Learn from the mistakes of others. Failure to do so will result in increased costs, not reduced costs.
