medical certification

Every aircrew member is required to be medically fit before he or she can assume flight duties. For pilots, there are three classes of medical certificates: Class 3 medical certificates are for private pilot duties only. They have the least-restrictive medical requirements, and the certificates are generally good for two years. Class 2 medical certificates are for commercial, nonairline duties, as well as private pilot duties. This certificate would be required of crop dusters, charter pilots, corporate pilots, and anyone else who flies commercially. The certificate is good for one year for commercial activities and two years for private pilot use. Class 1 medical certificates are required for pilots of scheduled airliners. They have the most stringent medical requirements, and the certificate is good for six months for airliner duties. Like the class 2 certificate, however, it is good for one year for other commercial activities and two or three years for private pilot duties. Medical tests must be conducted by an authorized medical examiner. These medical certification classifications are valid in the United States, but similar practices are in use in most countries around the world.
