Message-ID: <176@midacs.UUCP> Date: Fri, 23-Aug-85 19:25:52 EDT Article-I.D.: midacs.176 Posted: Fri Aug 23 19:25:52 1985 Date-Received: Sun, 25-Aug-85 02:08:05 EDT Distribution: net Organization: EG&G Idaho Inc., Idaho Falls Lines: 22 I now have an oportunity to get some right seat time in a Cessna Conquest. I was amaised to find out how dumb the expensive RNAV computer was that is on board. It does'nt do any great circle calculations, just straight from waypoint to waypoint. Does anyone have any software (for un*x or hp 11c calculator) that will allow me to do something like the following: give starting lat/long give destination lat/long give number of waypoints to plot along the great circle route get lat/long for waypoints 1 to n With the lat/long of the waypoints I could program the RNAV to approximate this great circle route. If not code, do you have any pointers to the algorithms??? -- Linn Hower Phone: 208-526-9353 ...!ucbvax!ucdavis!midacs!isew02!linn
