Traffic patterns can be defined as left-hand or right-hand according to which way the turns in the pattern are performed. They are usually left-hand turns because most small airplanes are piloted from the left seat (or the senior pilot or pilot-in-command sits in the left seat), and so the pilot has better visibility out the left window. Right-hand patterns will be set up for parallel runways, for noise abatement, or because of ground features (such as terrain, towers, etc.). Unless explicitly indicated otherwise, all traffic patterns at non-towered airports are to the left. Because the active runway is chosen to meet the wind at the nearest angle (with take-offs and landings upwind), the pattern orientation also depends on wind direction. Patterns are typically rectangular in basic shape, and include the runway along one long side of the rectangle. Each leg of the pattern has a particular name. #aviationenglishasia #aviationenglish #BasicAeronauticalKnowledge #flighttraining #AviationTheory #GroundSchool #PrivatePilotLicence #CadetPilotProgramme http://aviationenglish.com/basic-aeronautical-knowledge-certificate-programme/basic-aeronautical-knowledge-certificate-programme https://www.instagram.com/p/B5HbKx6BES7/?igshid=1wfvtdrnhjuvk
