2010-03-20 Thread David Megginson
There's a bug in the /instrumentation/nav/radials/selected-deg property: the code mistakenly assumes that the selected radial is in true degrees, but isn't a bearing -- it's just a number. You could design a VOR where radial 180 was north of the VOR, if you wanted to (though usually it's close to

Hmmm, the nav database had the actual radial alignment of the station relative to true north and I remember sorting that out so that when you fly off a chart, everything would be in chart-agreement when you flew to radial intersection points. Bummer if that got broke along the way ... I haven't

Hi James, The nav radio does not work in magnetic headings. It works in which ever alignment the station was setup in. In the 60's when GEP was installed, it was aligned with magnetic north at that time. In the subsequent years, the actual magnetic north has shifted several degrees, but the

SInce this is related , I'll ask here . I've got a 2 pointer RMI well under way , and according to the few documents I found , the RMI gets its input from the ADF and Nav receiver ... it doesn't do the calculations itself. So is better to NOT to use the /nav/heading-deg ? Cheers
