What happened? Saying they moved off centerline and hit the wingtip on the runway sign. Wake or something?

Just listened to the YouTube and said they didn’t hit wake but instead had an uncontrolled 45* bank roll to the left. Yikes. https://youtu.be/Ca-0Bi2lZhg

Guessing strong crosswinds that night.

I've observed the need to use full roll input on the bus in the ground effect environment due to gusts. Some people wish it had more authority.

Roll spoilers deploy once the side stick is moved laterally just past the point where the sidestick position indicators (the cross) touch the black center box.

Too much spoiler in a crosswind (Airbus recommends using rudder only) will dump a wing. Having the wing drop can lead to over correction as the pilot tries to recover.

That’s the scenario that makes the most sense here. It will be interesting to see what comes out of this. I don’t think AA Airbus training even talks about roll spoiler control on cross wind takeoffs.

They do. But I had a former LAW CKA as a sim P. He was awesome.

There is an article on Airbus' Safety First monthly newsletter #15 Feb2013. For all those that don't mind further AB reading, the "Safety First" App is a good resource where you can download specific topics.

The wind was right to left.... Upwind correction would have been to roll right. They impacted the left wing. Who knows for sure.

I don’t know about the 320 but that is not what airbus recommends on the 330.

Begin the takeoff roll with the sidestick approximately centered. During the takeoff roll, gradually increase sidestick displacement into the wind only enough to maintain approximately wings level.

Note: Excessive sidestick displacement during rotation and liftoff increases spoiler deployment. As spoiler deployment increases, drag increases and lift is reduced which results in reduced tail clearance, a longer takeoff roll, and slower aircraft acceleration.

At liftoff, the aircraft is in a sideslip with crossed controls. A slow, smooth recovery from this sideslip is accomplished by slowly neutralizing the sidestick and rudder pedals after liftoff before the aircraft transitions from the ground mode to the flight mode (approximately 5 seconds).

That's not the procedure for the 320.
