  Chapter 14: Airport Operations › Wind Direction Indicators

  Wind Direction Indicators It is important for a pilot to know the direction of the wind. At facilities with an operating control tower, this information is provided by ATC. Information may also be provided by FSS personnel either located ... none of these services is available, it is possible to determine wind direction and runway in use by visual wind indicators. A pilot should check these wind indicators even when information is provided on the CTAF at a given airport…

  Chapter 14: Airport Operations › Traffic Patterns

  Traffic Patterns At airports without an operating control tower, a segmented circle visual indicator system, if installed, is designed to provide traffic pattern information. [Figure 14-38] Usually located in a position affording maximum visibility to pilots ... providing a centralized location for other elements of the system, the segmented circle consists of the following components: wind direction indicators, landing direction indicators, landing strip indicators, and traffic pattern indicators. A tetrahedron is installed to indicate the direction…

  sense. Proper pre-flight planning, giving ample consideration to winds and weather, knowledge of the terrain and pilot experience in mountain flying are prerequisites for safety of flight. Continuous visual contact with the surface and obstructions is a major concern ... less dense air at altitude, this same indicated airspeed actually results in higher true airspeed, a faster landing speed, and more important, a longer landing distance. During gusty wind conditions which often prevail at high altitude fields, a power approach…
