Does anyone know how big of a problem this is? Does it limit the
cross-wind performance? So even though it's vtol the ship has to be
pointed into the wind etc?

It depends on the ship, but the Osprey has to deal with the same sorts of
problems when hovering over buildings on land.

The trick is that the pitch of the two props isn't fixed to be the same
value so it can adjust for uneven lift.

Navy Ch-46's deal with this many times a day as they resupply all the ships
in the fleet from the biggest to the smallest. Not a problem.
