Apperent Bug in DME

Featured Replies

Could a couple of somebodies out there give a check on this?My DME won't ID itself properly. The DME will give the correct distance to the VOR tuned to NAV1 or NAV2, but when asked to ID itself, it gives the last VOR that was tuned in by a tunable DME. The only aircraft I can find that has a tunable DME is MortonM's Piper Archer III. I guess by tuning a VOR in that aircraft, the frequency stays in preferences after leaving that aircraft.I would like someone to check that there DME functions properly without the Piper Archer III being installed. I hate to have to take all my preferences out just to check this. I will if I have to, that is if no one checks for me.I have turned in a bug report on this by the way. I don't know if it is ideed a bug, or the fault of the Archer III.

Its not the Archer III doing this. I still have ver 10 beta 7 so I wiped out the preferences on this made sure the Archer III wasn't in the sim, and the DME still IDs a different VOR than I am tuned to. it in fact IDs an ILS of 111.70.I'll turn this in as a bug! Hopefully I won't be the only one.

Hi Donald,I just tried in the CRJ 200, and everything seems fine. I went to CYYZ and tuned in 112.15 and got the correct code (-.---.----..). I then switched location to CYXU and tuned in 117.20 (-.---..-..-) and it gave the correct code. I don't have the Piper Archer. I hope that's what you were looking for.Glenedit: I'm running 10.04 Beta 1. I'll try a flight a see if it changes enroute, instead of just changing locations.

The VORs Id correctly, but did you check the DME Id? The DME Id never changes it is set to a frequency of 111. 7 unless you tune it with a tunable DME i don't think that any of the GA aircaft have a tunable DME.Setting in the default copy of 10.3 beta 7 at KSEA, the DME Ids rnwy 16C. changing to the SeaTac VOR the DME Ids still as the rnwy 16C, changing to Paine VOR the DME still Ids as rnwy 16C. It should be IDing whatever is in The NAV1 frequency setting. Some of the heavy metal may have tunable DME I don't know as I haven't had the time to explore the heavy metal, I normally don't do airliners. I'm a GA guy mostly.edit: The DME acts the same in all versions of XP10 including the 10.04 beta 1

Don, maybe I'm confused. If I'm sitting at runway 6R at CYYZ, their are 3 DME's. If I input anyone of those into the NAV1 radio the needle comes alive, it moves. Is this what you talking about? Here's a screen shot of CYYZ and the DME's. They all seem to work in the Cirrus, and the CRJ, haven't tried others yet, don't know why they wouldn't work.Glen

No not exactly Glen, I don't currently have Canadian scenery in so I can't go to our airport, but setting there tune different VOR in then have the DME Id in morse code. I can't get my DME to change frequency as an example:I am at KPWA Wile Post KPWA my NAV 1 is tuned to PWA frequency 113.40 The CDI is showing up OK and the DME is showing the correct distance to the VOR 0.1 mile and NAV1 ID in Morse as PWA. Now when I have the DME Id it self it IDs as a runway ILS at Tinker AFB RnWy 12 at 111.70 frequency. Again I can tune NAV 1 to the Kingfisher VOR frequency 114.70 id is IFI, but the DME although showing the correct distance, (23miles) to this VOR still IDs in Morse code as RnWy 12 which is IPLH on a frequency of 111.70.This effect is for the DME only, if it is a bug which I believe it is, it isn't really a serious one and probably doesn't effect most people. Probably most people anymore can't read Morse code anyway so don't have an idea any problem exists, again it is only a monor problem. :smile:I can tune the DME but the only GA aircraft that I can find that has a tunable DME is MortonM's Piper Archer III. I cannot find another GA aircraft that has a tunable DME.

Don, I just tried the default C172 at CYYZ sitting at a gate, and cycled through the 3 DME's, 109.1, 109.3, 110.95, in the Nav1 radio, and the morse code identifier changed each time I changed frequencies. Don't know what it could be at your end.GlenThis is what I hear from the radio:109.1 = .. .--- ...109.3 = .. -. ...-110.95 = .. - ---

Must be something in my setup. hat is what I was wondering about. Good job and thanks.

No problem at all, I hope you get it sorted out.Glen

Just to make sure Glen, did you turn of the Identifier switch for NAV1 and turn on the DME switch, that is the last to the right and to the top switch on the COM panel just above the Marker switch???

Don, in the C172, this is how it was set, as you described.Glen

Glen your Nav1 is still on, as evidenced by the green light in the Nav1 switch. make sure that the green light is out and I'll bet that the dme will ID on a frequency of 111.70 as that is what was set in the default program. Thanks for helping me out, and me being such a pill. :smile:I went to CYYZ yesterday, and set up for a flight to CYYB, couldn't use real world weather yesterday, the wind was gusting to 38 knots. A little to strong for timid pilots such as myself. :(

Don, you have to have the NAV1 selected, otherwise you hear nothing. You are tuning the NAV1 radio, and the DME is tied to the NAV1 in Xplane as far as I know . If you can hear a morse code identifier with only the DME selected, your hearing is a lot better than mine, because I don't hear anything. :( As far as I know, it's always been this way. It was like this in version 9, nothing has changed in 10. If this is not the way it works in ther real world then yes, it's a bug. But, it's always been like this since I started with Xplane. Goran, or one of the aircraft modellers for Xplane would know a lot more about this than me. I know in FSX you can hear the identifiers without having the NAV1 selceted.P.S. I'm not a real world pilot, so what do I know.Glen

This is what I thought Glen. The reason you don't hear the DME ID itself when only it is selected, is because you don't have a VOR or an ILS within your range. If you go to a place that has a VOR or an ILS with a frequency of 111.70 then you will hear the DME ID itself. When you do you will find the DME has a different tone a higher pitched ton than either NAV 1 or 2 or an ADF. Currently you are hearing only Nav1 ID for you. If you would like to test this out go to KPWA this is Wiley Post in Oklahoma City turn on only the DME wihout Nav1 or any other ID'er on and you will hear The ILS for runway 12 at Tinker AFB ID itself in the DME. Or go back to Seattle KSEA runway 16C and you will hear the DME ID I think that is runway 34 left. Can't remember if that is the correct ILS but at any rate that is what the default DME was set to and you will hear a Morse Identifier. The only aircraft I can find that has a tunable DME is in MortonM's Piper Archer III, maybe that is why he put a tunable DME in his aircraft. With that aircraft you can change the DME frequency. Actually in the sim its really not that big a deal, its just one of the little things that bug you when you know its not quite right, or worse you don't know if something is wrong with your own setup. :biggrin:Yes a DME should ID itself without the Nav1 just to double check in real life that that is the correct DME. In real life we can get class E skip with VHF transmissions, and get stations tuned in hundred occasionally thousands of miles away. Normally VHF radio transmissions are line of sight, but when E skip propagation is available, I have talked to ham radio operators in Hawaii from California, using less than 10 watts of power in the 2 Meter spectrum. That is close to the aircraft band around 127 Megahertz or so. That is unusual but does happen, and I have heard VOR's ID here in Oklahoma and Tex. when I knew they are up in Kansas.

Don, you are absoloutly correct. See, told ya I didn't know what I was talking about...I went to KSEA, sat at a gate, and hit the DME button, no NAV1, and sure enough I got:.....--....Which is the identifier for localizer 111.7. I switched to the frequency for the SeaTac Vor as well, and still got the morse code for 111.7, even though I had NAV1 selected as well as the DME.Now I understand what you were asking. My apologies for perhaps giving you a run around.Glen
