Hangars or open shelters offer protection from extreme weather. Each runway is assigned a number which is determined from the magnetic direction of the runway. The number is usually idsplayed on the approach end of each runway in large numberals that are easily read form the air. The runway number, of course, is different at each end of a runway strip because the magnetic directions are 180 degrees apart. Each airport has a traffic pattern for approaching and departing traffic.
Large airports have air traffic controllers that guide aircraft through that pattern.
NASA is working to help air controllers handle the ever-increasing volume of traffic in the nation's airspace. Arrange a visit from a local pilot to discuss how your local airport operates.
