ABSTRACT:
A draft monitoring device (10) for measuring and displaying the difference between the air speed and the ground speed of a motor vehicle (12). The draft monitoring device (10) includes a ground speed sensor (30) and an air speed sensor (46). Outputs from the ground speed sensor (30) and the air speed sensor (46) are compared to determine the direction and magnitude of the wind in the environment in which the vehicle (12) is being operated. The respective outputs are compared by a processor (64) carried within a housing (56) mounted inside the vehicle (12) in a position such that the driver of the vehicle (12) may easily view a display (68) carried thereon. The air speed sensor (46) is carried in a substantially undisturbed air stream on the front of the motor vehicle (12). The display panel (68) is provided for displaying the instantaneous, peak, and average headwind or tailwind.
