  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…

  approach path that will serve as go/no-go points should the pilot feel any assessed parameter is being exceeded. Wind direction and velocity are assessed as a medium risk because (for this scenario) the direction of the wind is slightly offset ... crosswind with a steady 10-knot wind. The pilot also takes into consideration that, due to the terrain, the wind direction and velocity may change during the approach. The pilot’s experience and awareness of the complexity of mountain flow…

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.

  LANDING AREA RECONNAISSANCE AND PLANNING

  seaplane bases have a windsock, but if one is not visible, there are many other cues to gauge the wind direction and speed prior to landing. If there are no strong tides or water currents, boats lying at anchor weathervane ... wind. Be aware that some boats also set a stern anchor, and thus do not move with changes in wind direction.
