Original HUD demonstrator model

Ferranti's FID-4500 Head Up Display was launched at Farnborough in 1982. The FID-4500 was intended as a low-cost replacement for gunsights of the ISIS type. Although its field of view is similar to that of the HUD on Tornado, the unit is small enough to replace ISIS, to improve weapon aiming or as part of an INS refit, and it will fit into the back seat position of all jet trainers.

The HUD was offered as part of a three-box system including the FIN-2000 miniature INS and the Type 105 laser. The unit has an upfront controller which performs navigation and weapon-aiming functions as well as controlling the HUD.

As well as the normal attitude and flight data, the HUD can show present position, waypoints, track/groundspeed, time to go (TTG), or wind velocity, and radio altitude is given on a circular pointer-display. Air-to-ground or air-to air weapon aiming can be performed on the HUD, close-in attack being automatic.

The HUD uses established components such as the CRT and some circuits from the map display COMED. A single card change is claimed to be sufficient to provide raster scan for night vision imagery. However the HUD operates in a cursive mode or an all raster mode and is not capable of providing cursive symbology over a raster display. . The PDU has a 25degree TFoV from a 4.5 inch objective lens.

The HUD was fitted to various A-4 and F-5 upgrades. This is the original demonstrator model of 4510 Series and is lacking the Combiner glass.
