Description should include the following:
- At most airports and military air bases, traffic pattern altitudes for propeller-driven aircraft generally extend from 600 feet to as high as 1,500 feet above ground level (AGL). Pilots can obtain the traffic pattern altitude for an airport from the U.S. Chart Supplement (formerly Airport/Facility Directory).
- At airports without an operating control tower, a segmented circle visual indicator system, if installed, is designed to provide traffic pattern information. It is usually located in a position affording maximum visibility to pilots in the air and on the ground and providing a centralized location for other elements of the system.
