Nico/Dave

Thanks for the input. Still having a couple of problems with amending the aircraft.cfg files to reflect the correct ICAO airline codes suggested. I change the title to a valid ICAO code using the correct syntax, save the changes but find that on running the sim subsequently some of the changes revert back to the original entries. Do you know if some of the IVAO models are write protected or am I doing something wrong by missing a step?

By the way the support offered is first class-many thanks.

Ian

It is indeed easier what Dave said, define your own regcode file as desribed in the Manual Appendix (then you do not need to edit aircrfat.cfg files):

In the input\my_regcodes folder, you may put one or more text files. The name is not relevant, but it must be unique, with extension .txt.

In the file one should specify the (exact) title of the livery followed by a semicolon, followed by a list of registration codes separated by commas. A livery title may not appear on more than one line.

Liveries that have just one registration code in an offline file, will be treated as being special, they will only show up as live aircraft, not as static parked aircraft.

 If you add ;# to a line, all registration codes will be treated as special, for example:

AIGAIM_easyJet Europe Airbus A320-200SL - Europcar;OE-IVC,OE-IVT;#

If you specify only a livery title, with no registration codes, PSXT will treat it as a “don’t use” livery.

Hi Nico

Thanks-I have created several regcode files so I will see how they perform.

Ian

Hi Nico

Had a chance to see what is happening but not sure I am getting the expected results. Here is an extract of my log:

17275 airports read

6269 liveries read from output\LiveriesScanned.xml

6269 livery titles

254 in-line regcode clashes, see 'output\errors\InlineRegcodes.txt'

6389 liveries read from AIG-regcodes.xml

1 livery read from input\my_regcodes\100ARS.txt

2 liveries read from input\my_regcodes\67SOS.txt

3 liveries read from input\my_regcodes\C5MGalaxy.txt

4 liveries read from input\my_regcodes\CC130J.txt

5 liveries read from input\my_regcodes\CV22B.txt

6 liveries read from input\my_regcodes\Ramstein.txt

Offline regcode files processed, results can be found in 'output\info\OfflineRegcodes.txt'

1946 special liveries

1900 unique liveries

23994 registration codes

759 airlines, 142 pax aircraft models and 43 cargo aircraft models

330 similar model definitions

I can see that the the myregcodes files that I have created have been read but taking Ramstein.txt(based C130's) as an example (but several other of my created my regcodes files are the same) I have 15 individual regcodes specified but only 6 have been read. Have I done something wrong or are the other regcodes being picked up elsewhere? Also I have had to specify the livery as IVAO_C130H as there isn't a C130J available through IVAO and is this where there may be a problem?

Ian

Normally PSXT will show in the log if there's an error in a regcode file. If they aren't showing up in the log at all, that is pretty weird. Can you post the contents and title of one of the regcode files that isn't working?

Using the C130H in place of the J isn't an issue. I have dozens of examples where I have subbed in retro liveries and types and they all work fine. AIG has converted the C130E, H and J's but there are limited packages available from them at the moment but you can add in your own custom ones.

Hi Dave

Thanks for replying. Here is the regcode file I created titled 100ARS:

IVAO_K35R;57-2605,58-0095,58-0100,58-0125,59-1464,59-1470,59-1475,59-1511,60-0324,60-0333,60-0335,60-0353,60-0355,61-0315,62-3540,63-8008,63-887

In this case the log shows only one livery having been read but just noted that the final code is missing an 8 at the end but presumably this should not make a difference.

The regcodes in your \input\my_regcodes\100ARS.txt are all mapped to the livery with title IVAO_K35R. Hence, if such a regcode is detected in RT data, PSXT will match that aircraft with that livery.

EDIT:

In the Log you must see something like this (example):
Processing regcodes file 'input\my_regcodes\test.txt'

2 liveries read from input\my_regcodes\test.txt

Edited Saturday at 12:37 PM2 days by kiek

Hi Nico

So what I'm seeing in the log is that RT recognised, for example, that one code out of the 15 include in the 100ARS regcode file was active at the time, and not that the file was not read properly?

Hi Nico

Yes I am seeing those sort of results but weirdly I tracked 4x KC45A aircraft into RAF Mildenhall a little earlier but despite having the exact regcodes for these aircraft, they displayed as an AIGAIM 757 model in USAF markings which I had previously downloaded through the aig-aitragfic-oci rather than the IVAO_B762 model within the regcodes file I had created.

Ian

You are meaning the KC46 (B762). Have you seen any other of the IVAO B762's working in the sim through PSXT? I know quite a few of the models don't work in 2024 for whatever reason. I can't say for the KC46 as I use an FAIB B762 painted to look like the KC46. It doesn't have the drogues or boom, but the model is sound and looks good. Same with the P-8, I use a newer MGAI model and it looks quite good!

Hi Dave

Thanks for the reply.Yes KC46-finger trouble! Can't say re any other IVAO B762's as I only have the MTL KC46 repaint. Interesting to hear that some of the models don't work in 2024 but the fact PSXT substituted the 757 might indicate it is not recognised. The only other thing I could think might affect it is the matching level which is set at 3 although why that should be the case I'm not clear.

Ian

So I added the MTL B762 and ironically it too is the FAIB just converted differently than how AIG did theirs. I'd still prefer to use the AIG version as I trust their quality more than any other AI dev. Matching at 3, you will see some different assignments. 2 is by far my preference.

As for why you aren't seeing them, again it could be something to do with modifying the MTL variants (I've had mixed success). The C17 for instance, is the same one used from MAIW and has EVERY operational serial, same with the E3A Sentry, T-6 Texan II as well as the T-38 Talon for starters.

I did notice for a few KC46's in my setup that PSX in the log said that the reg was unknown or something similar so maybe I'll forward on the regcode that I have on them so far and see if that helps.

The Log shows the matchings, post it here then I can have a look.
