The RMI, the dbl line yellow arrow, the single line green arrow and the defualt KIng Air

Featured Replies

Hello,I have noticed when flying the defualt King Air 350 and tunning to navigational frequencies that the dbl tellow line arrow is tuning to the radio signal in the VOR II radio, and the green single line arrow is responding to the freqency in the ADF radio.I thought I remembered in the FAA Insturment Flying Handbook, chapter 7 pg 7-4 that the dbl yellow arrow should respond to the ADF freqency in the radio stack and the single green arrow to the Nav II signal. I know there is a link in the learning Center to this FAA book, one day I will learn to post pics in the proper format, LOL. I am wondering if somehow I have slaved (assined) the to needles in the RMI to the opposite radio. I dont know if this is possible in FS9. Also the RMI could be set this way and it is correct and I have my info all mixed up. I would like to understand the way the Needles are assined in FS9 on the defualt King Air, and or what I am doing wrong.I appreciate any imput.Thank you.Mark.

That's a toughy, the plane I'm flying now has EFIS, I can't even remember what the nav 2 or adf needles look like, I think they're both single needles just different colors, don't use them that much with that nice FMC.Anyway, I believe the double needle in an analog RMI should be the vor and the single is the adf, that's the way most I've seen are.

Here's where it gets tricky, you have your choice of the ADF or VOR that you want the needles pointing to via a switch on the RMI, here in the www.tinmouse.org 737-200 I have the double needle on nav 2 and the single tracking the outer marker NDB of the ILS 5R (same runway, different direction) and the DME of the nav 1 and nav 2 above the needles.http://forums.avsim.net/user_files/119178.jpg

The needle assignments in the default Beech Kingair are, as you have discerned, backwards. It's a simple enough problem to fix by unpacking and editing the RMI's XML gauge file contained in the Beech_Baron.cab file.Simply use WinZip (or XP's zip utility) to "un-cab" the file, load the RMI.xml file in Wordpad.exe, and swap the two A: variables around...

I think your book is screwed up, double needle should be VOR, single ADF.Here's a link to the FAA Instrument Flying Handbook, Chp. 4, RMI descriptoin is about halfway down the page.http://www.faatest.com/books/IFRH/49.htm

Yeah, your book, the new FAA Instrument Flying Handbook is wrong, the old book that I posted a link to above is correct. The IFR training simulator that the pictures reference in your book can be downloaded free at the link below, fly it and you'll see they made a mistake and the double needle is NAV 2.http://www.asa2fly.com/category1.asp?SID=1&Category_ID=151&

Thanks 737. What is the link yo yhe current FAA Insturment Handbook. Yea, the pic you had from the old book was not found in the current Handbook. Thanks for your imput.

Bill,THank you for your responce. I am aware of unzipping, at least with winzip as you mentioned. But I am lost in what is to be copied and paste to the file that you mentioned. Maybe this means I have no business messing in this file. Hey, I can paste to a config file in order to add a new paint job to a plane, LOL.So even if the assinment in the defualt 350 is backwards, it sounds like as mentioned above that there is a switch to slave the green or yellow needle to the either the VOR II or NDB. I am asking as I am away fromn home tonight and cant reference the sim to see the dash of thr 350 to locate the mentioned switch. Well at least I am asking myself if I am crazy. Hey as long as "I saw what I think I saw," LOL.I would like to try and correct the file as you kindly mentioned.Take care. I should be home and try by the afternoon.Mark.

The Kingair is NOT backwards, your book is. The Kingair is exactly the way it should be, your book and the poster that said the Kingair is wrong are backwards.Do like I said and download the free sim that the FAA used for that example picture that is in your book, here's the link http://www.asa2fly.com/category1.asp?SID=1&Category_ID=151& you'll see when you fly it that the FAA made an error and that the double needle is the vor and not the adf, the FAA made a mistake in the picture (below) in your book.http://forums.avsim.net/user_files/119384.gif

You are absolutely, 100% correct sir! I was in error. *:-* I relied on that innacurate illustration in the FAA book to program a dual-needle RMI...In retrospect though, looking at a picture of the KI 227 single-needle ADF indicator makes it quite obvious that the narrow "single-needle" is for the ADF radio, hence the "double needle arrow" must be the VOR indicator... ;)

Hi,I don't think which radio is attached to the single vs double needle is a "required thing", or at least is wasn't always so. In fact, most airliners in past days used an RMI where the source of the signal for both needles could be set individually. Thus, they could be one VOR and one ADF (either way), two VOR's, or 2 ADF's. All depended on a switch setting.That said, if the assignments are fixed it would be nice to see that described in the text file. :)Hope this helps,
