Four lights are positioned in a square. When a directional correctional signal from an autopilot exists for a predetermined length of time and is above a given magnitude, lights at one or the other sides of the square are lighted to indicate that face and the direction involved. When a pitch correctional signal from the autopilot exists for a predetermined length of time and is above a given magnitude, lights at one or the other ends of the square are lighted to indicate that fact and the particular pitch involved.
An aircraft control position indicator is provided that displays the degree of deflection of the primary flight control surfaces and the manner in which the aircraft will respond. The display includes a vertical elevator dot/bar graph meter display for indicating whether the aircraft will pitch up or down, a horizontal aileron dot/bar graph meter display for indicating whether the aircraft will roll to the left or the right, and a horizontal rudder dot/bar graph meter display for indicating whether the aircraft will turn left or right. The vertical and horizontal display or displays intersect to form an up-down-left-right type display. Internal electronic display driver means receive signals from transducers measuring the control surface deflections and determine the position of the meter indicators one each dot/bar graph meter display. The device allows readability at a glance, easy visual perception in sunlight or shade, near-zero lag in displaying flight control position, and is not affected by gravitational or centrifugal forces.
