  Chapter 10: Advanced Flight Maneuvers › Maximum Performance Takeoff

  obstructions on the departure path and can significantly affect aircraft performance. There are several ways to check the wind direction before taking off. One technique is to watch the tops of the trees; another is to look for any smoke ... there is a body of water in the area, look to see which way the water is rippling. If wind direction is still in question revert to the last report that was received by either the Automatic Terminal Information Service…

  Chapter 11: Aircraft Performance › Performance Charts › Sample Problem 10

  AFM/POH. The crosswind and headwind component chart allows for figuring the headwind and crosswind component for any given wind direction and velocity. Sample Problem 10 Refer to Figure 11-31 to solve this problem. First, determine how many degrees difference ... there is between the runway and the wind direction. It is known that runway 17 means a direction of 170°; from that subtract the wind direction of 140°. This gives a 30° angular difference or wind angle. Next, locate…

  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…

  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…

  Chapter 5: Aerodynamics of Flight › Wingtip Vortices › Avoiding Wake Turbulence

  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…

  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. There is usually a glassy band of calm water on the upwind shore of a lake. Sea gulls…
