Are there stringent medical requirements?
No. The FAA 3rd class medical exam is a piece of cake. If you can get into the doctor’s office unassisted you pass. Well, almost. Really high blood pressure is a problem. But vision generally isn’t. You can wear glasses as thick as old Coke bottles and still pass if your vision is reasonably correctable. Believe it or not, even one eye is OK. So is heart bypass surgery, after testing to prove that you have completely recovered. However, mind-altering drugs like Valium or Prozac are disqualifying.
