An airman is a member of an air force or air arm of a nation's armed forces. In certain air forces, it can also refer to a specific enlisted rank. An airman can also be referred as a soldier in other definitions. In civilian aviation usage, the term airman is analogous to the term sailor in nautical usage. In the American Federal Aviation Administration usage, an airman is any holder of an airman's certificate, male or female. This certificate is issued to those who qualify for it by the Federal Aviation Administration Airmen Certification Branch.
