Having installed this very realistic addition,I am at a loss as to how to determine which signal (A or N) is appropriate. Having flown radio range many years ago in real life I am certain the charts we used showed an A or an N in the appropriate quadrant.I have downloaded the airway charts & airway data info. All that remains is- do I fly the N or the A? Any help would be much appreciated.

Having installed this very realistic addition,

Which one would that be? :(

Try a Google search for "Radio Range Navigation" There are lots of results which might help, like this...http://www.centennialofflight.gov/essay/Evolution_of_Technology/navigation_tech/Tech33.htm. Learnt it during Harvard training (1955) but can't remember how to use it now. :unsure:Colin B

Thanks Colin. Will give it a try

Neither. When you are flying in the N sector, you will hear the Morse code ident for N; flying in th A sector, you'll hear the ident code for A. So Im sure you can see that N + A equals a long tone: .- and -. put together gives a ________ . Okay. The long dash is the course; however, there are 4 different courses, so you need to know where you are in relation to the cone. You need to find and study and understand the system, and all the info is available, or was, at the DC-3 Airways web site. There is a lot to learn, and depending on your background, might be quite difficult. Or, in today's speak, expect a steep learning curve. By the way, contrary to current ideas, if you are lost in relation to the cone, there is a procedure to locate yourself, however, it is a complecated procedure and rather lengthy- timewise. Don't ask me how because I don't remember. I do remember Vicky, tho. Quite well, that was back in '53, or was it '54, and she was......db.

Hi,Normally they flew a little to the right of the solid tone, to avoid head on collisions with planes going the other way. Whatever letter that was (A or N), they flew with that side a little stronger than the other.Hope this helps,

In Google Earth you can display stations and beams with A/N sectors (white side of beams=A, black=N) using apollosmith's excellent GE overlay (and database).http://smithplanet.c...s2004/tools/rr/GE overlay with RR Airways (rr4_airways_google_earth_overlay.zip): http://www.flightsim...rth_overlay.zipPS: You'll certainly also also want to load Ian Niblo's GE overlay with Airports, VOR and NDB (fsxge.zip) into Google Earth.http://library.avsim...iblo&CatID=root).(All: Plenty of information available by clicking into stations, beams, ect.)As for detailed instruction on how to fly the Ranges, in addition to the very good instructions coming with RR40, there are several 40's navigation manuals available, e.g. at http://aafcollection.../items/list.php "Air Navigation" (item 198)"Instrument Flying: Basic and Advanced" (item 149)and at "Basic Air Navigation" http://library.du.ac...e/handle/1/9653Gunter

GunterYour first suggestion was the missing piece in the puzzle ie. white/black-A/N. I now recall that the charts we used 50yrs ago used yellow/blue-A/N.ThanksC.V.
