I noticed when I upgraded to fgfs 0.9.9 there seems to be support for TACAN now, but I can't figure out how to get it to function. Does it work?
FlightGear/Navaids$ zgrep HIF nav.dat.gz 12 41.120503 -111.963681 4806 11120 0.000 HIF Hill TACAN 4 41.104047 -111.959581 4775 10990 152.980 IHIF KHIF 14 LLZ 6 41.137167 -111.980497 4780 10990 280151.963 --- KHIF 14 GS 8 41.149389 -111.990497 4560 0 151.963 --- KHIF 14 MM If I set the DME freq to 111.20 I can read the HIF TACAN DME. Looking up that freq in TACAN_freq.dat yields channel 025Y: FlightGear/Navaids$ zgrep 11120 TACAN_freq.dat.gz 025Y 11120 If I set the TACAN to 025Y near HIF /instrumentation/tacan/in-range remains "false" Web sources suggest the TACAN at HIF is channel 49. If I set the TACAN to 049(X/Y) near HIF /instrumentation/tacan/in-range remains "false" Found these pages: http://microvoltradio.com/tacan.htm http://www.angelfire.com/mb/amandx/vuhffreq.html I guess the numbers in TACAN_freq.dat are in 100s of KHz instead of 10s of KHz like in nav.dat.gz. So channel 49X is 1,010.0 MHz not 101.00 MHz like I was reading it at first. It seems the 111.20 MHz DME in nav.dat.gz is correctly assosciated with TACAN channel 49X, and FlightGear treats it like any other DME, which I guess it is. Is there a way in FlightGear to pull the DME freq from a TACAN channel? Is there a way to get data into /instrumentation/tacan/ ? ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
