Fatal Error On transmit after changing new agency Frequency

Post by Julaibi » Mon Apr 01, 2019 3:46 pm

Hello Everyone

I am running Prepar3D v4.4 with VoxATC v7.42 and Active Sky P3D4 on Networking.

Everything is updated using fsaerodata and Navigraph softwares with Cycle 1904

i encounters some issue with one Leg of Flight From OMDB to OBBI when i start my flight everything run smooth from push back all the way to descend once the VoxATC switch me to Bahrain Approach with Frequency which is 119.100 i dial it and transmit i got Fatal Error without respond from the agency after i tried to change the Frequency to Bahrain tower and transmit i hear the tower report message Go a head with no further instructions.

After I disabled VoxATC and enable it still Fatal Error.

I flew the opposite Leg from OBBI to OMDB everything runs Smooth from push back to land and taxi to gate without any issue.

after i flew on different Flight plan still the issue exists.

any idea and Help Please could someone help me to fix this issue.

Thanks



Best Regards

Hello,
this type of error on VoxATC are quite hard to troubleshoot since there is almost no log or trace stored on the application VoxATC itself that can lead to the source of the problem, either the app itself or fsAerodata database.
In the past there were some issues related to VoxATC and FSAD, but related to a conflict with airports that changed the ICAO code.
I'll do some tests with a default system, and let you know,

Hello Sir

I did investigation today and I noticed that a flight from OMDB to OBBI with FSaerodata updated to Cycle 1940r1 I got that issue VoxATC with Fatal Errors Disable.

And I fly with same Route without FSaerodata everything was running smooth, so I think the problem came from the STAR Procedure at destination and Approach Frequency Bahrain Approach 119.100.

And you can check that issue sir.

I have been trying to figure this error out also:

https://www.avsim.com/forums/topic/5523 ... nt-3990423

The VOXATC message in the error log indicates (within my limited understanding) that a .NET exception occurred while enumerating the OBBI approaches. One interesting thing that you can check is that if one runs Little NavMap and displays the approaches for OBBI with fsaerodata installed, there is a difference between the sim's database ("Do not use Navigraph database") and the "Use Navigraph for all features" options. The difference is that the built-in LMN Navigraph database has the STARs ending lined up with the final approach path to the runway, whereas the fsaerodata Navigraph version does not:

This might be something specific to how LNM displays approaches or it could be a clue.

Jose,

Take a look at the OBBI VORDME approaches. They seem a bit odd. It probably only takes one approach to mess up the entire collection.

Re: Fatal Error On transmit after changing new agency Frequency

I think that I figured this out. OBBI has duplicate VOR DME approaches (one for CAT A/B and one for CAT C/D) for both 12L and 30R. Both VOR DME approaches have the same name. Somehow this is causing the error in VOXATC. Without fsaerodata, these approaches are missing. This all makes sense. As VOXATC adds the approaches to its collection, it generates an exception, because the approach type already exists in the collection.

The question becomes, how to fix it. It could be fixed manually by editing OBBI.BGL and deleting the duplicate VOR DME approaches, but that seems a bit tedious, especially if OBBI isn't the only airport where this occurs.

Here's the official AIP entry for OBBI, which is up to date:

http://www.bahrainaims.com/aisjune14/20 ... en-BH.html

EDIT.

I don't think that this is the issue as I checked a couple of other airports that have multiple transitions for VOR DME approaches and they seem okay. There is something about the OBBI approaches that is causing VOXATC problems, but without Tegwyn West's help, we'll probably never figure it out.

Jose,

I did some more testing on this. I created a new version of OBBI from the fsaerodata stock airport with ADE. The first thing that I noticed was that some time during 2018, the OBBI on-airport VOR ident was changed from BAH to BHR, probably because there is a duplicate VOR with the ident BAH in the UK. I deleted all comms, approaches and used raw (XML) mode in ADE to rename the VOR to BHR. I then added back the approaches from the fsaerodata PROC BGL file to the ADE airport. I added back the AIRAC 1904 comm frequencies. Compiled and re-indexed with VOXATC and guess what? I was able to fly ILS and visual approaches into OBBI with no FATAL ERROR. However, if I requested a VORDME approach, VOXATC gave me vectors to the hold and told me to report at the hold point. But the interesting thing is that it referred to the VOR ident as BAH! As soon as I reached the hold point and reported, VOXATC generated a FATAL ERROR. Here's a link to a zip of the airport files, which I placed in a folder with the highest priority in my scenery library:

https://www.dropbox.com/s/0fp4lk5hos7xz62/OBBI.zip?dl=0

None of this makes any sense to me. The fsaerodata OBBI.bgl file has no reference to anything but the BHR VOR. The Level D 767 folder only refers to Lat-Long coordinates and not the VOR ID. I have no other versions of OBBI installed and I've checked everywhere, not the three ORBX Vector airport folders (since I disabled all of them) or any other potential 3rd party scenery folder. Any thoughts? Where is the reference to VOR BAH coming from? Is VOXATC picking up the VOR ID from the stock airport file APX61220.bgl? Maybe you could change the stock file so that just for OBBI, the VOR ID is changed to BHR and see if that fixes it.

The BHR navaid is a joint on some nearby airways, and it's used on the FSAD airways database. You can see where it's located selecting it on the Little Navmap app.
I don't understand the point of having a duplicated VOR as long as it's not on the same region; actually FSX/Prepar3D uses the region code to differentiate navaids with same designators.
As said before, without some detailed logs from VoxATC where the errror comes from, it's really hard to figurer oout this kind of generic errors.
