TWY

Definition of TWY

A taxiway, also known as TWY, is a designated path on an airport field that allows aircraft to move safely between runways, aprons, and other areas. It is a essential component of an airport’s infrastructure as it enables aircraft to maneuver and park at the terminal, hangars, or other facilities without interfering with the activity of other aircraft using the runways.

The purpose of a TWY is to reduce congestion on runways by offering a separate and quicker route for aircraft to make from one spot to another. It can be identified by its distinct pavement markings, usually in yellow, and the blue lights at the edges of the path that guide pilots navigate the taxiways during times of low visibility, such as at night or in adverse weather conditions.

The width, length, and design of a taxiway depend on the type and size of the aircraft it will be serving. They must be wide enough to accommodate the wingspan of the aircraft and provide enough clearance for the aircraft’s tail and other parts to avoid collision with other planes and ground equipment. The construction of a taxiway also considers the turning radius of the aircraft it will support.

In conclusion, TWY is an integral part of the overall airport system that enables safe and efficient operations of aircraft. It is a crucial mechanism that helps aircraft to move between the runways and other areas, while minimizing the need to cross active runways, which can cause significant disruptions and increase the risk of accidents.
