Markus Schober 1328585 Posted March 20, 2018 at 04:44 PM Posted March 20, 2018 at 04:44 PM After spending some time searching for a VOR/DME based RNAV computer from the time before GPS became a thing (a.k.a. Rho-Theta RNAV - where you virtually moved a VOR station to the desired waypoint) for flight simulator use without much success, I decided to take things into my own hands, did some research and, eventually, replicated the Bendix/King KNS 80 as a gauge for FSX. What started as a small project matured quickly and became a solution that works impressively well. Actually so well that I asked myself if I should make it available to the public. The system consists of two gauges: the actual KNS 80 RNAV computer, programmed according to the manufacturer's "Pilot's Guide KNS 80" and a Garmin 102A CDI instrument, specially made for compatibility with the RNAV computer, for displaying the course deviation The gauges contain carefully edited and thoroughly animated artwork and enact the original system's functionality to the extent permitted by the flight simulator, and just like the real computer, the gauge does all the maths with the information from the tuned VOR/DME station - there is no cheating or tampering with GPS variables. Features include: VOR mode: CDI acts like a standard course deviation indicator, the needle shows deviation in degrees, 2 degrees per dot, 5 dots from center to each side VOR/PAR ("parallel") mode: CDI shows course deviation in nautical miles, 1 NM per dot RNAV/ENR ("enroute") mode: CDI shows course deviation to the selected course to/from the active waypoint (virtually moved VOR), 1 NM per dot RNAV/APR ("approach") mode: same as above, but 1/4 NM per dot 4 waypoints (defined by VOR frequency, waypoint radial and distance) can be edited and activated using the RNAV computer's rotary knob and buttons RNAV computer display shows distance, ground speed and time to station/waypoint While the source code is authored by me, I [Mod - Happy Thoughts]ume that I need agreements from the copyright holders of the source images, as well as the owners of the trademarks and possibly even design patents used in the work before publishing it, even though I intend to make the gauges available for free. So before getting headaches from that legal stuff, I would like to know first: Is there anyone at all out there who would be interested to use these gauges? If yes, drop me a PM.

Magnus Meese Posted March 21, 2018 at 02:15 AM Posted March 21, 2018 at 02:15 AM I'm flat out impressed, I've never even heard of anything KNS80-like used or even working in FS. I'd love to geek out with this system should you make it available. Great job! Link to comment Share on other sites More sharing options...

Markus Schober 1328585 Posted March 21, 2018 at 01:29 PM Author Posted March 21, 2018 at 01:29 PM RNAV computer mounted in a virtual cockpit RNAV Computer as windowed gauge, CDI in virtual cockpit (highlighted), GPS as proof-of-concept reference Programmed waypoint: OKIBA, which is shown on the charts located at 109.2 LBU VOR, Radial 355, 18.1 nm (programmed radial and distance cannot be seen in the screenshot, they share the display with the frequency and are shown when pressing the DATA button) Deviations match (GPS in TERM mode: 1 line = 0.5 nm, RNAV in APR mode: 2 dots = 0.5 nm). Distances and ground speeds match. (You will notice that the OBS knob of the CDI, while still being perfectly operational, does not really fit into the 3D knob of the default C172's virtual cockpit. Making it fit should not be a big deal, but only if requested because I'm not going to use the system on that plane) Markus Link to comment Share on other sites More sharing options...
