Most aviation schools require that students have a high school diploma or GED certificate. Prior math and physics classes are also beneficial, since flight theory uses a lot of physics knowledge and basic math skills. The Federal Aviation Administration requires that aviation students be at least 16 years old.
Many aviation schools require that potential students obtain a medical certificate of health and physical competency from a qualified doctor. This entails a physical exam to ensure that the candidate is healthy enough to operate the equipment. Some aviation schools also require candidates to undergo a psychological exam because it is one of the FAA requirements for pilot licensing.
If a student plans on flying for a commercial airline, they will need a two-year or four-year college degree in a related field in addition to flight training. Individual airlines determine this requirement.
