The aviation industry has long debated the minimum flight hours required for pilots to obtain an Airline Transport Pilot (ATP) certificate, a prerequisite for serving as a pilot in command at major airlines. Currently, the Federal Aviation Administration (FAA) mandates 1,500 hours of total flight time for most pilots seeking an ATP certificate, although certain exemptions (e.g., for military pilots or graduates of approved aviation programs) allow for reduced minimums—known as a Restricted ATP.
