Hello all, I recently did a checkout in a 172. The flight lasted 1.1 total. My preflight brief with the CFI was no more than five minutes as he had just hopped out of another plane and I had already preflighted. After we landed we did a postflight briefing that also lasted roughly five minutes and that was that. He charged me 1 hour ground along with the 1.1 hour hobbs and 1 hour of flight instruction. We really didn't even do ANY ground... He says that is just the industry standard and every flight school will do that. I've been checked out at over ten flight schools and not one of them has charged for more ground than we actually did, even when I got my high performance in a 300hp 182. This is utterly ridiculous as we did less than ten minutes ground and now I'm $60+ down the hole. Any thoughts?
