Approach and Landing Situation Display

The Elliott Approach and Landing Situation Display is a head-up display which presents to the pilot simple and unambiguous information of autopilot state and the aircraft’s position relative to the flight path. The display is associated one with each left and right monitored autopilot, radio altimeter and radio systems, and is designed for mounting on the top surface of the glare shield, one in front of each pilot, such that it does not interfere with the pilot’s normal field of view.
The design was proposed for Concorde and for the VC10 but was not ever fitted.
