Yes you are right that the source is not along with the real-life. And it will take some time to adjust that. I'm not talking about the frequencies in EDDP its just an example what happens using the apt.dat source. I think in real world the stations have a well defined output power. So that they don't interact with there neighbours. Made a quick intersection test on the actual positions.txt file of fgcom. every station with every station on the same frequency. 6993 stations Range 50 nm : 3498 intersections Range 100 nm : 9262 intersections Range 150 nm : 16736 intersections Range 200 nm : 25734 intersections Range 250 nm : 35920 intersections Range 300 nm : 47650 intersections My vote stays for a dialbook layout: icao, frequency, lat, lon, type, name, range, server, number So fgcom can dial a number on a server, connect if in range to a station. And we can establish relay stations. work to do for this DB - Initially build by apt.dat source. ranges by station type according to real life. - Adding correction for the most atced airports( and neighbours ) in fg . - Adding one 100nm Range frequency for each Airport for ATC(all in one desk). - Summarize all center/radar frequencies to dial one number for the center- controller desk. fg should read this DB to display frequencies. fgcom should read it too ;-) openradar i don't know ? distribution : for me terrasync, then we can get a fast update rate of the dialbook. merge git delivered by terrasync. features: - split traffic to several server - less frequency intersection - better frequency coverage - high update rate - possibility to establish a center-controller desk Regards, Dirk ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
