Abstract
An avionics display (10) for use in an aircraft navigation system including a navigation receiver. The avionics display (10) includes a needle (12) for indicating the position, heading, glide slope or other navigational parameter of the aircraft and a stepper motor (14) coupled with the needle and responsive to the navigation receiver for driving the needle in response to the navigation signals received by the receiver. The stepper motor drives the needle at a much higher torque than prior art displays and is therefore less sensitive to contaminates and magnetic interference and is less fragile.
