There was a large round, color, CRT (PPI if you're that old) with icons, each designating an aircraft. Each designation included a tail number. I noticed many duplicate tail numbers.

This is the second time in several months on this digest where a piece of airplane related software showed lack of airplane domain knowledge. I hope that the real FAA software is loaded with executable assertions, integrity checks, etc. to INSURE that duplicate tail numbers could NEVER appear anywhere in North America or whatever the system boundaries are. The demo software would not have to be the real software of course. Its just amazing to me that with all of the pilots and air controllers floating around our society noone would catch such a discrediting error. Also I don't view scenario generation for a marketing display to be such a big challenge. I would get some radio receivers and tape record ATC-pilot traffic for 5 minutes. Then play them back and write down the scenario. Here in Florida I've heard "You have me going 400 knots in the wrong direction", "You put me over the field at 10,000 feet" but mostly just routine ATC steering commands and pilot reports that translate easily into a script. Of course I could extend the artificial neural network based scenario generator for Harpoon weapons officer training that was developed on my Navy project so that a "richer" scenario would appear (if anybody really cares please contact me for more info). sam harbaugh
