Offset 085C is wrong???


Recommended Posts

Hello,

I noticed that offset 085C has strange behavior

The manual says:

VOR1 Latitude in FS form. Convert to degrees by Ok-SimC N/A
*90/10001750. If NAV1 is tuned to an ILS this gives the
glideslope transmitter Latitude.

But sometimes it reads the VOR1 latitude not the NAV1 latitude When there's an ILS
Same problem with the longitude, offset 0864

I checked with the FSUIPC logging in a window, when a few times I swap the frequency, it gives the wrong result, it's very inpredictable.

So in my program it reads about I guess 20% wrong.

Have someone  a solution?

You'll need to state which Flight Simulator you are talking about, and which version of FSUIPC.

If you use the Monitor facility in FSUIPC Logging tab, right-hand side, then, assuming you are using FSX or later, not FS9 or before, then FSUIPC will log exactly the value it receives from SimConnect, along with the Sim Var name. If this is wrong it points to either a bug in that version of F, or possibly a bug in the nav data in the scenery.

FSUIPC doesn't manipulate the data received except to put it into the same units as FS98, FS2000, FS2002 and FS2004 used to provide. It does this to provide ongoing compatibility.

FSUIPC 4949c

First off you need to update to the currently supported version 4.974. The one you are using is very old. Check on fsuipc.com

Only after you'd done that, add the monitoring as I requested and show me the log file after a session in which you see the problem. Please note down what I should look for.

Hello Pete,

Thank you for helping me.

I see nothing weird in the log


Tested on EDDK RW 25 freq: 109.100
swap freq: 111.100
Output in FS windows gives:

I started with no Ils and no VOR gives 0 (111.100)
First swap was wrong gives number 5652010 the same as the VOR
2e gives 0 is ok
3e gives 5652883 is ok
4e gives 0 is ok
5e gives 5652010 and is wrong

For FSX is this no problem the ILS is working fine

The log tells me nothing I'm afraid. In the Monitor facility please make sure you check the "normal log" option so the entries appear in the log. We need to show that it is SimConnect providing the wrong value.

 

Monitor the offset you are concerned with (085C) as type U32, then show me the log pointing out where you think the Sim is getting it wrong. And please DO NOT use the "New Log" button to make FSUIPC start a new log. I also want to be able to see the initialisation entries! AND close the session and show the complete log please.

Unfortunately, even if we gather solid proof that FSX is in error, it won't get fixed. But maybe Iit can be tested in P3D4 so that L-M can be asked to fix it.

Oh, i'd also need to know that both the aircraft and scenery in use is default, and no NAVAID updates from Herve Sors or FSAeroData. Otherwise L-M won't want to know.

Look at the end of the log, where it goes wrong. 
Reads the latitude and longitude ok and then:

 1021713 Monitor IPC:085C (S32) = 5652010

the number now is: 5652010 must be 5652883

Aha! Okay, so the SimConnect value is correct, but something is going wrong in FSUIPC after it is received.

I'll check it out in FSUIPC5 as I am now set up to debug that rather than FSUIPC4.

It might not be for a couple of days as I've got a lot of prior stuff to get through.

Actually, reading the documentation more carefully, it appears that 085C is supposed to be the VOR latitude, always. Offset 0874 is the same except when NAV1 is tuned to an ILS in which case it is the ILS latitude.

So, if there is an error, isn't it that 085C isn't maintaining the VOR latitude when NAV1 is on an ILS?

I'll look at the code, but I'm wondering if the problem is actually more to do with when the NAV1=ILS indication is provided by SimConnect. If there was a delay it would explain the change you are seeing, albeit very quickly. Whether it is an ILS is indicated by bit 7 in offset 0C4D. The SimConnect variable for that flag is "NAV HAS LOCALIZER".

So, could you repeat the test but not only monitor 085C, as you have, but also 0874 (also a U32), and 0C4D (as U8).

Then you could see if you get the results you want with offset 0874 .

Hmm, that is very strange. Are those bits of log immediately after you did a "swap"?

I'll need to find time to check this on FSUIPC5 ... maybe over the weekend. Please remind me if I haven't got back by monday. I seem to have a lot on and, being old, tend to forget and mislay things (I've written a Note to myself and left it on my desk! 😉

After further investigation I noticed that when you make a go around that after about 4 miles out
it change also to the VOR without changing the radio frequency or something else.

Maybe the ILS reception has faded too much to be recognised -- did you check the flag which determines this?

I think not because the ILS identifier also not changed.
Wich flag do you mean?
When you mean offset 0C4D then Yes:
on approach bit 7 and 6 set (192) near touchdown bit 7 (128) halfway runway bit 3 and 5 (40)  and then bit 7 set (128) at the same time change to the VOR.

Yes, 0C4D bit 7.

I'm afraid I've got problems to sort out here befre I can investigate this (I think I need to reinstall windows), so it will be later in the week.

In any case if it is a bug in FSUIPC I can get it fixed in an FSUIPC5 release, but I'm not sure about FSUIPC4 which was frozen a couple of years back (after 14 years of continuous development). Seems odd no one came u with the problem you report in all that time?

I'll let you know what I can do. What do you use the Lat/Lon/Alt value for when on Approach, exactly? And just for clarification , are we talking about the VOR signal for the localiser, when you want the ILS glideslope transmitter location?

I check the distance from the plane for an ILS aproach with a glideslope in a graphical chart, when the distance is wrong then the plane is of the glideslope, i have made a work around but this is not 100% proof.

So I imust have the lat/lon/alt from the localizer not the VOR , the alt is always good

see this video:https://www.youtube.com/watch?time_continue=39&v=lDk3JpNb5mw&feature=emb_logo

Ofcourse in this video is all working well.

So you don't use the glideslope deviation value in offset 0C49? Prefer to do it the hard way?

You've also got 0C48 for the localiser deviation.

Looking at the video you linked to, I'm not sure how this relates.  There are changing moving Lat/Lons for a ship -- I didn't even know they had VORs/ILSs!

Hey, it's not the hard way it's another way. 

It's very simple infact:

I know thw planes height
I know thw runway height
I know the glideslope degrees
And when I also know the correct distance is it very simple

Example:

at 1000 feet with a glideslope of 5.50 degrees the distance = 1.709 Nm.
at 1000 feet with a glideslope of 3.00 degrees the distance = 3.140 Nm.

So when the plane is on the glideslope at 500 feet and the Glislope is 3.00 degrees distance is then 1.570 Nm.

When on the glideslope at touchdown the distance is 0 Nm.

In the graphical is the end of the glidesope 0 Nm. I must know this point and that is the offset we talk about.

My question was is the offset wrong or I'm wrong.
Have you test it on your Machine?

When I know for sure the offset is not wrong I must do more investigation.
When the offset is wrong I must live with that.

Sorry, I've been 100% tied up trying to get my setup back up in time for a visit I've got tomorrow (travelling from Australia) to do some updated visuals for my cockpit.

I haven't forgotten, and should get around to testing this during this week.

Meanwhile, because even if there is a problem in FSUIPC with timings regarding SimConnect callbacks (because that is what I am suspecting), I can get it fixed in FSUIPC5 which is still in development, but probably not FSUIPC4 which stopped development over two years ago.

This is why I thought you might use the deviation indications instead.

Today I finally managed to start tedting this for you -- but on P3D4 using FSUIPC5, as I said.

I used the same details as yourself, excepting as there's no Cessna I used the Baron 58.  On the threshold of Runway 25 at EDDK with 111.10 and 109.10 on NAV1.

Offsets 0C4D, 085C and 0874 each reported correctly, and were correct on every swap of the frequencies. I repeated this many times till came to the conclusion that it just wasn't going to go wrong.

The data from SimConnect always arrived in exactly the same order, every time, the sequence for 109.10 being:

  2614717 SimRead: 0C4D="NAV HAS NAV:1" [also 0C4A]
            INT32: -1 (0xFFFFFFFF)
  2614717 Monitor IPC:0C4D (U8) = 0x0
  2614717 SimRead: 0C4D="NAV BACK COURSE FLAGS:1" [also 0C4A]
            INT32: 131 (0x00000083)
  2614717 Monitor IPC:0C4D (U8) = 0x40
  2614717 SimRead: 0C4D="NAV HAS GLIDE SLOPE:1"
            INT32: -1 (0xFFFFFFFF)
  2614717 Monitor IPC:0C4D (U8) = 0xC0
  2614717 SimRead: 0C4D="NAV HAS LOCALIZER:1" [also 0C4A]
            INT32: 1 (0x00000001)
  2614717 Monitor IPC:085C (U32) = 5652883
  2614717 SimRead: 085C="NAV GS LATLONALT:1" [also 0864] [also 086C]
            FLT64 Lat=50.86704724, Lon=7.152247131, Alt=92.04901123
  2614717 Monitor IPC:0874 (U32) = 5652010
  2614717 SimRead: 0874="NAV VOR LATLONALT:1" [also 0878] [also 087C]
            FLT64 Lat=50.85919004, Lon=7.120706588, Alt=92.04901123

and then for 109.10:

  2616714 SimRead: 0C4D="NAV HAS NAV:1" [also 0C4A]
            INT32: 0 (0x00000000)
  2616714 Monitor IPC:0C4D (U8) = 0xE8
  2616714 SimRead: 0C4D="NAV BACK COURSE FLAGS:1" [also 0C4A]
            INT32: 0 (0x00000000)
  2616714 Monitor IPC:0C4D (U8) = 0xA8
  2616714 SimRead: 0C4D="NAV HAS GLIDE SLOPE:1"
            INT32: 0 (0x00000000)
  2616714 Monitor IPC:0C4D (U8) = 0x28
  2616714 SimRead: 0C4D="NAV HAS LOCALIZER:1" [also 0C4A]
            INT32: 0 (0x00000000)
  2616714 Monitor IPC:085C (U32) = 0

  2616714 SimRead: 085C="NAV GS LATLONALT:1" [also 0864] [also 086C]
            FLT64 Lat=0, Lon=0, Alt=0
  2616714 Monitor IPC:0874 (U32) = 0
  2616714 SimRead: 0874="NAV VOR LATLONALT:1" [also 0878] [also 087C]
            FLT64 Lat=0, Lon=0, Alt=0

So,  since the coding in FSUIPC5 in this area is identical to that in FSUIPC4, I can only conclude that it is a bug, or data timing error, in the SimConnect in FSX SP2.

Have you never thought of updating at least to FSX-SE which had a number of corrections to bugs in FSX, and which was also recompiled with more modern versions of the compiler, leading to more efficient code. Alternatively, if you don't want to move to proper 64-bit, P3D3 would be a good choice. (Though I do not currently have dbugging facilities for either, I'm afraid).
