The measurement system uses behavior of the International Standard Atmosphere where atmospheric pressure descends with increasing altitude and two pairs of measurement units. Each pair measures pressure at two different positions that are mechanically connected with known distance between units, e.g. the units are mounted at the tips of the wing. In the horizontal flight, there is no pressure difference measured by the measurement system which means the position angle is zero. In case the airplane turns the tips of the wing mutually changes their position, one is going up and the second one is going down, and the pressure sensors in every unit measure different values which are translated into a position angle.↑"@en }
