Ted, the problem is ice can't build up on the wings specifically. Ice on the wing interfears with the airflow and affects the lift. Enough ice build up and there is no lift at all. The fusalage doesn't matter as much, the only penalty here is added weight and drag. However on DC-9 type aircraft, they will deice the entire plane to keep ice from getting sucked into the eingines. >Without or without computers, how is wind & direction computed during >flight? I don't think you can...a plane buzzing at 500 miles an hour would pretty much make any direction or velocity detection difficult, if not impossible. I must also ask, why would anyone care?
