In aviation, the standard Visual Flight Rules (VFR) traffic pattern is a rectangular circuit used to coordinate arrivals and departures at an airport. The five legs are: 1. Upwind (or Departure) leg, which is the flight path along the extended runway centerline after takeoff; 2. Crosswind leg, a flight path at right angles to the runway; 3. Downwind leg, which is parallel to the runway in the opposite direction of landing; 4. Base leg, the flight path at right angles to the landing runway from the downwind leg to the final approach; and 5. Final Approach, the descending flight path in the direction of landing. Pilots typically enter the pattern at a 45-degree angle to the midpoint of the downwind leg. Understanding this sequence is vital for pilot communication and safety, as it ensures all aircraft are moving in a predictable "flow" around the airfield.
