Centaurus,

Interesting point.
The necessity to release the braking force in case of weathervane is explained in the fctm.
Sops should and normally provide reduced cross winds 'limitations' for braking action good or less.

The disengagement of AB in that condition and reduction of reversers do increase the landing distance.
However a landing with a touchdown between 1000 and 2000 feet should not end up into an overrun even with temporary release of brakes.

In any case,crews should be familiar with theiraircraft landing distance along with safety buffets(dispatch 1.67 rule),and the effect of crosswind,speed at threshold,possibility of weathervane.....
There should be a MAX touchdown point in every captain head before any landing,if one passes that point,go around should be initiated.
