Other variants of the equation are possible; for example, the geostrophic wind vector can be expressed in terms of the gradient of the geopotential height ? on a surface of constant pressure:
12.
"I believe they provided even more than they'd get at a busier airport, because it appears they were getting periodic wind vectors, " he said of the descriptions of wind direction and speed.
13.
If the laser receiver is placed on this wind stabilized reference, the angle that the laser is off the wind vector is the same as is measured relative to the centerline of the seeker.
14.
"' Leeway "'is the amount of drift motion to leeward of an object floating in the water caused by the component of the wind vector that is perpendicular to the object s forward motion.
15.
:: It is helpful to think of these speeds as projections of the relative wind vector on to the three body axes, rather than in terms of the translational motion of the vehicle relative to the fluid.
16.
The rotation of this bar to the selected angle mechanically represented the wind vector relative to the aircraft . At the end of the wind bar is the " wind screw knob ", which is used to set the wind speed.
17.
Above 1750 ft, the axes of the turbulence coincide with the Earth frame " z "-axis, the longitudinal turbulence axis is aligned with the projection of the mean wind vector onto the Earth frame's horizontal plane, and the lateral turbulence axis is determined by the right hand rule.
18.
A consistent, repeatable path cannot be defined for a turn that allows for a fly-by turn at a waypoint ( because nearness to waypoint and wind vector may not be repeatable ), requires a fly-over of a waypoint ( because wind vector may not be repeatable ), or occurs when the aircraft reaches a target altitude ( because target altitude is dependent on engine thrust and aircraft weight ).
