A320 Crossover Angle of attack

SavedByTheTCAS: I am just wondering if anyone has asked / done / seen this before and in what conditions.

Yes. On TriStar (L1011), it sometimes felt like you would run out of aileron authority when aligning with the runway during a landing in strong crosswind (e.g. Bermuda). The learned technique was to land with up to 5 degrees of crab remaining and 5 degrees of into wind bank.

Have a read of the Lufthansa A320 at Hamburg 2008 AVHerald incident report . The Full BFU report.
Despite full side stick by both Captain & FO, the aircraft still rolled to 23 degrees whilst a wheel was on the ground. The BFU report mentions "The limited effect of lateral control was unknown." the aircraft went in to "Ground Mode" (only half aileron deflection during on ground logic above 80 kts) - hence loss of aileron authority.
