Abstract : A digitally activated display scale in association with digital-electronic circuitry, display both the airspeed and airspeed trend of a landing aircraft. The digital/electronic circuitry process an analog voltage corresponding to an airspeed range of 80 to 179 knots to produce a digital number representative of the airspeed of the landing aircraft. The digital number is used to produce a continuous display of the airspeed and to indicate the trend of the airspeed as either increasing or decreasing.
