QBlade is a public source wind turbine calculation software, distributed under the Academic Public License. The software is seamlessly integrated into XFOIL , an airfoil design and analysis tool. The purpose of this software is the design and aerodynamic simulation of wind turbine blades.
The headwind is about 22 knots, and the crosswind is about 13 knots. [1] To determine the crosswind component in aviation, aviators frequently refer to a nomograph chart on which the wind speed and angle are plotted, and the crosswind component is read from a reference line. Direction of travel relative to the wind may be left or right, up or ...
The aircraft is said to have 7.5 knots of crosswind and 13 knots of headwind on runway 06, or 13 knots of tailwind on runway 24. Aircraft usually have maximum tailwind and crosswind components which they cannot exceed. If the wind is at eighty degrees or above it is said to be full-cross.
Dynamic soaring is a flying technique used to gain energy by repeatedly crossing the boundary between air masses of different velocity.Such zones of wind gradient are generally found close to obstacles and close to the surface, so the technique is mainly of use to birds and operators of radio-controlled gliders, but glider pilots are sometimes able to soar dynamically in meteorological wind ...
Cirrus uncinus ice crystal plumes showing high-level wind shear, with changes in wind speed and direction. Wind shear (/ ʃ ɪər /; also written windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere.

Ground speed can be determined by the vector sum of the aircraft's true airspeed and the current wind speed and direction; a headwind subtracts from the ground speed, while a tailwind adds to it. Winds at other angles to the heading will have components of either headwind or tailwind as well as a crosswind component.
Crosswind leg. A short climbing flight path at right angles to the departure end of the runway. Downwind leg. A long level flight path parallel to but in the opposite direction of the landing runway. (Some [who?] consider it to have "sub-legs" of early, mid and late. Certainly a plane giving a position report of "mid-downwind" can be visually ...
