One thing that's forgotten here is that on the bus at 50' radio altitude it starts coming out of Normal and goes into ground direct or flare law at this point your sidestick inputs are directly to the control surfaces. And you can place it into a forward slip ie; crosscontrol. Landing the airplane in a cross wind is just as Breckster mentioned and is the technique we teach. With the loss of both radio altimeters the bus goes into direct law when the landing gear is extended. Which as it implies sidestick movements go right to the control surfaces, and allows one to cross control. What must be remembered about Normal law, is your asking for a load on the control surface which the flight control computors limit. All this airplane wants to be at is 1G in flight. Also after takeoff the bus blends into normal law from ground direct law. This all starts happening at 50' radio alt. And it's possible to cross control during takeoff. You just have remember when this thing changes from your normal airplane and into a big Aircoupe.
