Yes, as long as I can pass a 3rd class medical, I can get a PPL and drive a certified plane. The problem comes when I can't pass a 3rd class and am restricted to the LSA category (as others are already). I tip the scales, bare naked, about 230 lbs. My doctor says I don't have any weight to lose.My wife struggles to stay below 180. That's 410 lbs. right there.
When we travel, we each have 25 lbs. of carry on, and a 50 lb. suitcase. That's another 100 lbs.
Most LSA's burn 5 GPH. If you want 3 hours of cruise, and 1 hour of reserve, that's 120 lbs.
So, 510 + 100 + 120 = 730 lbs.
I'm also 6'3", and have broad shoulders. I don't know of many LSAs with that kind of useful load, with enough head and shoulder room for me. Heck, I even have trouble finding certified, or Experimental planes that fit. I can barely shoehorn into a Skyhawk, and I turn a C-152 into a single seater.
But, I doubt I'm the only one in this boat.
