A display for aiding the pilot of an aircraft in anomalous wind environments. Wind velocity components are measured by an instrument 11, processed by a computer 12 and a vector generator 17 and then displayed as a vector 34 on the display shown in FIG. 3. A signal F indicative of flap position selects a flight validated lift curve which is displayed as a lift curve channel 42. During normal wind conditions the cursor 35 marking the termination of vector 34 is in the channel of curve 42. However, during wind anomalies cursor 35 moves outside the channel. It then becomes the task of the pilot to control the aircraft such that cursor 35 will move back into the channel.

A method for controlling an aircraft whenever there are wind anomalies in the path of and a distance from the aircraft comprising the steps of: generating a first signal proportional to the velocity of the wind in the direction of the aircraft heading and parallel to the Earth\s surface at said distance from the aircraft, a second signal proportional to the velocity of the vertical wind at said distance from the aircraft and a third signal proportional to the ground speed of said aircraft: processing said first, second and third signals to produce a vector of the relative wind velocity on a display; selecting a lift curve, the lift curve being the locus of points at which the lift is equal to the weight of the aircraft during normal winds; and displaying said selected lift curve on said display such that the cursor endpoint of the displayed said vector is superimposed on said lift curve during normal winds; whereby whenever the cursor endpoint of the displayed said vector is not superimposed on said displayed lift curve the pilot knows that wind anomalies are present at said distance from the aircraft and thereby can make appropriate maneuvers with the aircraft.
