I'll just chime in here to be sure to clarify some of the good advice already given.
- If you intend to fly SP, and have no real desire for 4-place certified aircraft, night flight, instrument etc. Then simply stick with SP and your driver's license.
- Once you apply for ANY medical, you have opened up the process and ANY denial means you loose your SP as well as any chance at PPL without going through a potentially expensive and lengthy process.
- The FAA medical process involves your ENTIRE history with a lot of "Have you EVER had... Have you EVER been arrested... etc.". Simply having been incorrectly diagnosed with something 10 years ago might lead to a LONG and $$$ process.
- If you want a CONSULT with an AME make sure it is just that, a consult. Expect to pay cash and do NOT fill out any FAA forms.
- Personally, if I was thinking SP and at 10 hours, I'd go ahead and finish up SP and get about 50+ hours behind me and then decide if I wanted to do any of those things that require PPL.
FYI the new basic med does require that you have passed at least a class III medical at least once in the last 10 years. So if, after consulting with an AME and digging thorough your own medical history, you (and more importantly the AME) are SURE you would be a "shall issue" then maybe go for it, because after that you can go basic med with just your personal Dr. for ever after.
When I started this journey 2 years ago, I too was confused and thought "why wouldn't I just want to get a medical". But it is quite a bit more complex a decision than that. Turns out that the plane I want to fly I need a PPL, so I am going that route. But I thought I would be a slam dunk for the medical (Im healthy, no drugs, no medications, etc). But that whole "have you EVER" stuff nailed me to the wall and it took me a year and $$$$ to get it done. If the plane I want was LS, I'd have gone SP.
