the only way to do it is to tell one harf of your brain that its ok to move that turn, and then when its the other side of your brain's turn bring on your air strike.
if it was me i would miss it out, its the same with scheduled art, you would avoid the area that you have picked for the art to land in.
the only other thing to do is to is to break down the table into smaller parts, i.e if you have a 6ftx4ft table mark area's on the table or a map showing 12"x12" or smaller then ( if you are useing a 6ft x 4ft table you would have 24 x 12" area's then roll dice to see what 12" area has the attack comming into it). you could make it harf the table that is the target area so it would be 12 x 12" area's. 3ft along the long side then 4ft across the short end. or something like this, im sure someone will come along and make this a bit more simple
