RE: IMAC "BOX" SIZE
"The answer I spoke of you wouldn't like is to bring back the box, prescribe centering as the center of the box and add a 200 meter flight path rule. This would likely make some 40% er's obsolete. Maybe not if the pilot can handle the airplane correctly. I submit you could fly the same size box as Pattern does right now. If you want to lower your "Foot print" these might be the changes that'll be required. I see Imac is going through the sound problem pattern fliers went through 20 years ago.
Is this subject worth debating in a meaningful way? I think so."
