A buddy of mine started PP training a long time ago, then had to give it up. He was just about to get started again, then had a heart attack. He's been getting the itch to start back into it, but needs to get his medical situation in order. One of the local FBOs now has a Cessna LSA, so no medical required. I just forewarded him some info from AOPA and Doc Bruce about the steps necessary to get his class-III. He may, or may not, decide it's worth the trouble. So, lets say he starts training as a SP student, and maybe even gets his SP. and suppose, down the road, he does commit to getting his class-III - if he then starts PP training, how much of the SP training will carry over? What about a transition from SP to PP? Are the minimum requirements similar enough that it won't be like starting over? Thanks.
