The gs-in-range prop is in CVS now. Next up is integrating your navradio-DME patch. > >> If you want to add a low-pass filter, that would >> be a Good Thing.

At EDDM, where the runway ends do NOT share an ILS frequency, I see an extremely stable GS response until I'm practically level with the GS transmitter (which is what I'd expect / hope). At EGPH, at about 200ft above the runway, the navradio suddenly picks the 'other' end, with, as they say, hilarious consequences. Actually the GS angle jumps from 3.0 degrees to 177 degrees, instantaneously. I suspect penaltyForNav is broken, probably by me - so that's where I shall look next. Torsten, it would be good if you could confirm my analysis, by trying some approaches in runways where the ends do not share an ILS frequency, and report on what you see. >> >> signal all the way to the runway, I'd say we have >> _two_ bugs (unrealistically good GS signal, and >> unrealistic autoland implementation). When the code is not being screwed around by conflicting GS transmitters, the behaviour is stable down to pretty much the runway surface. I think that's 'good', for the moment; if in the future someone wants to add code to make the GS less perfect, that's fine with me (possible controlled by a /sim/realism flag) Regards, James ------------------------------------------------------------------------------ Come build with us!
