Headwind and Tailwind are opposite interpretations of the wind component which is parallel to the direction of travel, [1] while Crosswind represents the perpendicular component. Determining the ground speed of an aircraft requires the calculation of the head or tailwind.
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 ...
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 ...
Ground speed is the horizontal component of the velocity of an aircraft relative to the Earth’s surface, also referred to as "speed over the ground". [1] It is vital for accurate navigation that the pilot has an estimate of the ground speed that will be achieved during each leg of a flight.
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 ...
On the main body of the flight computer it will find the wind component grid, which it will use to find how much crosswind the aircraft will actually have to correct for. The crosswind component is the amount of crosswind in knots that is being applied to the airframe and can be less than the actual speed of the wind because of the angle.

The apparent wind is the wind experienced by an observer in motion and is the relative velocity of the wind in relation to the observer. [citation needed]The velocity of the apparent wind is the vector sum of the velocity of the headwind (which is the velocity a moving object would experience in still air) plus the velocity of the true wind.
