GEC Avionics Limited
In the early 1990s the US Federal Aviation Administration (FAA) began a flight test programme of a synthetic vision system (SVS) to gather data for that certification. The SVS was a joint programme with the US Defense Department to develop technology enabling low visibility landings on what they called "cooperative" and "non-co-operative" runways. Their Gulfstream II test bed was equipped with a HUD and both IR and MMW, to balance the advantages and disadvantages of the two sensors. The pilot was able to switch between the two sensors initially, but there were plans to blend the images later.
GEC Avionics supplied an overhead HUD system made from F-16 and C-17 components and a separate electronics unit located in the avionics bay. Kodak supplied the mid-wave IR and Honeywell and Lear two different MMW radars. The MIL-STD-1553 interface was replaced with an ARINC 429.
The Electronics Unit is from this Gulfstream II "Synthetic Vision Experimental Program". It later went on to be fitted to a BAC 1-11 research aircraft by Westinghouse in Baltimore to support their Boeing supported "ESAS" program in concert with Honeywell, and eventually led to the Honeywell connection with Marconi Avionics.
This unit has lost the original label shown here in the earlier photograph.
