  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 ... receive and broadcast on this frequency. When 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…

  desired track and the heading of the aircraft necessary to keep the aircraft tracking over the desired track. Wind direction indicators. Indicators that include a wind sock, wind tee, or tetrahedron. Visual reference will determine wind direction and runway ... lack of adequate navigation signal directly above the VOR station causes the needle to deviate. Wind shear. A sudden, drastic shift in windspeed, direction, or both that may occur in the horizontal or vertical plane. Zulu time. A term used…

  speed of 10 knots causes the vortices to drift at about 1,000 feet in a minute in the wind direction. When following another aircraft, a pilot should consider wind speed and direction when selecting an intended takeoff or landing ... decrease the lateral movement of the upwind vortex and increase the movement of the downwind vortex. Thus a light wind with a cross runway component of 1 to 5 knots could result in the upwind vortex remaining in the touchdown…

Flags, pennants, streamers can also be used. When describing ... estimate velocity. Also, report if the wind conditions are gusty, or if the wind direction or velocity is variable or has changed recently. 5. If any obstacle(s) exist, ensure their description, position and approximate height are communicated…
