Alternate Airport

Alternate Airport

Alternate Airports are airports that are marked along an aircraft’s flight plan that can safely accommodate the landing of the aircraft, should the aircraft experience an emergency or if the landing at the intended airport becomes inadvisable. Alternate Airports are basically back-up landing sites, just in case something goes wrong during the flight and a different airport must be used for landing.

Alternate Airports are usually marked so that a pilot is always aware of their location, in case he does need to make an emergency landing. For commercial airliners, these airports are usually other large, commercial airports that have a long enough runway to support such a large aircraft. A few examples of when an Alternate Airport may be used include if the desired runway has a disabled aircraft on it, if weather, like snow or a bad storm, does not permit a safe landing, if the airport’s control systems malfunction, or if the aircraft has an emergency.

In an in-flight emergency when a pilot must land the aircraft immediately, the closest airport that can support the aircraft is the first airport that the pilot should turn towards. Aircraft that have emergencies are moved to the front of the flight pattern so that it can land before the other aircraft. During an emergency, smaller, light airplanes can usually land just about anywhere that is long, flat, and free of large obstacles that would impede a landing.

Alternate Airports help to ensure the safety of the passengers and crew of the aircraft and allows an emergency to be dealt with more quickly and efficiently.
