Back to: "T"traffic pattern
- Definição1
- The regulated movement of air traffic that must fly along an established route when approaching or leaving an airport. Airplanes fly very precise rectangular patterns around an airport prior to landing. Each side of the rectangular has a name. The leg flown at right angles to the runway immediately after takeoff is the crosswind leg. The leg flown parallel to the runway and opposite to the direction of landing is the downwind leg. The base leg, as it is known, is flown ate right angles to the runway, just before turning to the final direction for landing. Flight in the direction of landing but maintaining altitude is called an upwind leg. Traffic patterns may be flown with either right-hand or left-hand turns.

- Definição2
- 1.The traffic flow that is prescribed for aircraft landing at, taxiing on, or taking off from an airport. The components of a typical traffic pattern are: upwind leg, crosswind leg, downwind leg, base leg, and final approach; 2. A published route prescribed for aircraft to fly when approaching or leaving an airport. The possibility of in-flight collision is minimized by all aircraft in the vicinity of the airport using a specific traffic pattern.

- Nota adicional1
- A normal airplane traffic pattern is rectangular, has five named legs, and a designated altitude, usually 1,000 feet AGL.
- Contexto
- A traffic pattern promotes safety by establishing a common track to help pilots determine their landing order and provide common reference. A traffic pattern is also useful to control the flow of traffic, particularly at airports without operating control towers. It affords a measure of safety, separation, protection, and administrative control over arriving, departing, and circling aircraft.
