[80 Seri]es Projection Unit
Type No. 229 SKD 15145
Ser. No. 101/68
Made in England
A new generation HUD, the Type 80 was introduced by Elliotts for the civil market in July 1968 and proposed for a number of British and European transport aircraft. The equipment comprised the Pilot's Display Unit, a Display Computer (waveform generator) and various ancillary units which together formed the instrumentation system.
The introduction of a laminar-beam CRT reduced the size of the Projection unit. The problem of the different symbol formats that were certain to arise between different airlines was accommodated by altering a single matrix board. Full self-monitoring was included and self-test to line replaceable unit level gave acceptable integrity.
The concept was essentially modular to allow installation in a wide variety of aircraft. An artists impression of a Type 80 installation in a VC10 shows the Projection assembly located above the pilot's head with a glareshield mounted Combiner. This was the type of installation actually used in the Varsity whereas the Belfast was entirely glareshield mounted. However only 3 of these Type 80 HUDs were delivered.
This item is the optical relay assembly and was probably made by Wray Optic in Bromley.
