Abstract
A meter face arrangement for use with a cross wind sensor that provides information indicating relative airspeed with respect to a probe, and also the direction of the relative wind, which permits an operator of an aircraft such as a helicopter pilot or an operator of a levitated vehicle or an observer in a ground installation to determine the relative movement of the air and also the relative direction of movement. The meter face is made so that the indicator will visually provide the direction and speed information from a single meter location using standard indicating hands to prevent confusion of the user.
