- A civil airport is an airport that is open to the public and primarily used for commercial, civilian aircraft operations. It is different from a military airport, which is used exclusively for military aircraft. Civil airports typically have facilities such as terminals, runways, parking areas, and other amenities to serve passengers and aircraft. These airports are owned and operated by civil aviation authorities or private entities, and they usually provide services such as passenger and cargo transportation, airline operations, and general aviation activities. Examples of civil airports include London Heathrow Airport, Los Angeles International Airport, and Dubai International Airport.
