But even if I was, what's that got to do with Mr Cessna blocking off half the windscreen with bleedin great instrument panel in a simple plane like a 172?
That migh be the case if you're three feet high. In that case, get a booster seat. Otherwise, the 172 has excellent visibility. I spent a few years flying tours, back country charter and all sorts of other things from banner towing to search and rescue to grand canyon charters in 172's, 182's, 206's, and 207's...the high wing Cessna's have always been popular because of their excellent visibility and unobstructed view.
Try raising your seat up a little higher.
