OMG, let's please not start modeling RNAV equipment for FS...LOL.I don't think we need to revert back to those days.

Well, I didn't do it because it was fun. I got paid to do it. LOL.

Haha, rgr that. Man, I can't even remember the last time I even saw a Loran.At first when I saw RNAV in this post I thought you were refering to SID/STAR's....rofl, that require like triple redundant GPS's and 8 different autpilots to fly them. How sad is that?Edit: You guys were actually refering to Loran, right? How embarassing.

No Jeff... I wasn't referring to a LORAN. I was referring to a VOR based RNAV. I recall just how excited my father was when he had one installed in his aircraft in 1972 and it did get a lot of use. Yes, the current GPS systems are so much better than the ways of the past and may the good old days never return. That doesn't take away the interest in simming with one for period type flights. The four course radio range simulation was certainly of interest to some simmers and I suspect a VOR based RNAV simulation of the 70's and 80's type equipment would also garner some interest.

Gotchya, I thought that we were somehow reverting back a few, my bad.I don't recall myself ever hearing about that type of Nav, of course I didn't come around til 1970.Interesting to learn of that, to say the least, thx.

OTS Jeff, but I am sure hoping that you all are able to get the Modesto scenery done. We used to use the RNAV for flights from KMOD to O22 which I grew up on a hill overlooking.

I knew you were going to say that...lol. We're cranking on all cylinders now, don't jinx us. :-)

Zane, very interesting topic. I remember my first exposure to this functionality in a friends Baron. He described the function as "virtual VOR" where he could set two VOR radial intersections as a "fix" and fly to it as if it were a real VOR station...he said he could set a "virtual VOR" any place he wished.:-)

Hi Ron :),We could always hope Fr. Bill gets an urge during some hiatus and whips one up.

>Hi Ron :),>>We could always hope Fr. Bill gets an urge during some hiatus>and whips one up.Ha Ha, my friends Baron now contains a 530/430 combination with Audio Panel/Transponder and the obligitory CD Player Sytem.:-)Guess he was ready to move on from the old avionics:-)

Yes and no...mostly no. The ICAO definition while correct, is highly generic. In common airman usage "RNAV" is a term of art which means a VOR-based navigation DEVICE (not "method of navigation")that creates a fictitious VOR when the radial and distance from an actual VOR is input into the box.What I mean is that if you went to your local FBO and told everyone that you just bought a brand new Garmin "RNAV" system you would get some combination of blank stares and chuckles.I can understand the original poster's yearning for some "old tech" since I had RNAV in two of my former aircraft...a C310 and then a 340. (In the 310 I had both RNAV and LORAN so I was double ancient). The RNAV worked well but since it is based on VOR signals, it suffered from the same inaccuracies...signal strength...wandering that the base VOR head suffers from.Obviously, creating GPS Waypoints is vastly more accurate but for a "blast from the past" an RNAV would be very cool...say in my Dreamfleet C310.Regards,Jim

Here is the one that is still being used in my Baron. I confess I have never used the rnav function as we have a kln94. However, we do use it for vor/dme and it has a nifty hold button which allows usage of the ils freq while still getting dme off another vor....You find a lot of these still in use on Barons of this time period (pre 1980 or so). There is no need to replace it as it works as advertized, and makes a nice legal backup for rnav navigation-which is probably why you still see a lot of these vs. a loran!http://mywebpages.comcast.net/geofa/pages/rxp-pilot.jpghttp://forums.avsim.net/user_files/153270.jpg

As a follow-up, I can confirm that it was indeed a KNS81. I can do some 'helpdesk-ing' if someone wishes to give it a go ;D

I'm game ;). PM me and I'll give you my email.
