You want to fly?
Just as you cannot take to the air as a Private Pilot without a valid pilot’s license, you can’t fly without a current Medical, which confirms that you have no disqualifying health conditions that would prevent you from flying as Pilot in Command. A Medical also serves as the basis of your own self-certification of health, which all pilots are required to affirm before every flight.
An FAA medical certificate is a medical certification required for almost all pilots to be able to fly an aircraft. FAA medicals are issued in 3 classes (1st class, 2nd class, and 3rd class), and are valid for different types of piloting activities. You will need to fill out an application for the medical, and then have a physical examination by an FAA approved Aviation Medical Examiner (AME).
A third-class medical exam is required for student and private pilots. There is no medical exam requirement for a sport pilot certificate.
A medical certificate requires an EKG initially at age 35 and at each exam at age 40 and older. An exception is the first-class exam that requires the EKG only once every twelve months, (i.e., at every other exam).
