John,
I have read quite a lot about the previously designed systems including the one by John Grover, ex ground instructor and tech perf expert and author. His was flight tested by the FAA in the early 70's on a Coranado 880, if you remember those !!
Also the Dutch NLR system and the NASA system that was tested in their interesting B737 flying test-bed that they used for developing the first CRT displays. Had a cockpit back in the cabin near the centre section !
I believe the Cranfield system, which has only recently been patented, stands a far higher chance of success mainly because of its simplicity of display format and readily retrofittable design.
I have also looked at the system proposed by Khwata at Bristol which again has a complex interface.
Thanks for your reply, if you have knowledge of any other similar systems that may be worth comparing with, please let me know.
JP
