The B-52F probably isn't the best example as it doesn't go through a 'rotate' 
phase.  The A-10 might be a better example but I think it still needs 
references to altitude-agl-ft changed to gear-agl-ft for it to work.  I think 
that the 2d panel that contains the A/P instrument may also still need to be 
fixed following the 'clipping' patch but the script should make more sense.
