Civil aviation is a major commercial and technological industry in the United States. The two major components of civil aviation activities are air carrier and general aviation. An estimated 278,000 people/day rely on air carriers for business and personal travel. As of 1991, there were approximately 6,054 air carrier aircraft, which include commercial air carrier operators, commuter air carriers, and air taxis. Aircraft types include jet, turboprop, piston, and rotary wing aircraft (helicopters), which flew an estimated 13.5 million flight hours. Besides the flight crew members, many aviation-related professionals (maintenance, flight line, airport support staff, etc.), who may never pilot an aircraft, depend on the air transport industry for supporting themselves and their families.
