I've joined a flying club and am in the checkout process for their 152. I've trained in it, was endorsed by a 20,000+ hour instructor (who felt comfortable enough renting his personally owned 152 to me after the checkride), and my DPE (who a commercial pilot tried to steer me away from due to her supposed high fail rate, i.e. she's demanding) thought I flew the plane well. I'm a very new VFR pilot with about 70 hours total, and find this checkout process is taking longer than usual under these circumstances. Has anyone gone through a similar situation? How have they dealt with the matter? The instructor is also making me feel less safe as a pilot doing things like banking with full flaps, and pushing "flap religion" on me (i.e. 10 on DW, 20 on base, 30 on final without really considering the approach environment). Due to W/B restrictions on the 152 he's the club's only viable checkout instructor.
It is normal for flying clubs and flight schools to require a checkout before allowing a renter to solo, which may take several hours, regardless of their license level or previous experience. They often require additional training if you dont have a certain minimum time in type.
Your club might be slightly more paranoid than average, but that probably translates to cheaper club insurance and thus lower rental rates, which means you will probably save money if you stick around.
Also, it should be noted that 70-200 hours is the period with the highest accident rate, so some paranoia on their part is probably justified. Even if it's "just a 152."
A five hour, 3 session checkout process does not seem appropriate for a Cessna 152. You'll have to look at the savings you hope to gain by doing your flying with the club, and decide whether it is worth it for you to continue. It would help if your question stated whether or not this lengthy checkout process was specified from the outset-- what was your initial expectation when you decided to check out in the aircraft? What sort of checkout procedure have other pilots been subjected to? Since we don't know how you fly, ultimately it is impossible for anyone to say whether or not anything inappropriate is going on. Maybe the instructor just has a different "style" of flying from you and since you are not really in a position to debate anything, you may just have to adapt even if it does take some time. As long as you are continuing with the process, you might as well try to learn something useful from the training, even if you don't fully agree with all aspects of your instructor's approach. At any rate, you should discuss your concerns with the club leadership. If enough people give the same input, some change might happen.
Or find another club.
