Hi Nico,

it`s me again. ;-)

I have been playing and experimenting around with the new version 15.5.0 at my favourite airport LGAV:

I really enjoy both accurate parking stand allocation as well as populated airports. So I tried different settings.

I noticed of course that with "RT Parked only" I get the most realistic parking as it is actually happening in real life right now but not that many aircraft at the airport (as written in the documetation).

When I check the Auto Park Function I get a well populated airport (the amount I put in target %) but unfortunately at the same time I`m losing a lot of the real life RT parked aircraft, which is a shame because it kind of kills the immersion a little bit again. (There was a message at the bottom, for example: "Parking Adjustments: 10 to be removed, 16 to be added"...sadly some of the 10 removed were very nice and accurate RT parked aircraft)

Therefore I was wondering if there is a mode to inject all the RT Parked Traffic first and keep it visible (as a priority, kind of) and then fill up the remaining empty stands to the desired target % with Auto Park?

I used your PSXT Tutor for more information and this is the quoted result:

"No there is no dedicated mode for that. The two modes follow different strategies:

-RT Parked Only: uses exclusively the parked aircraft data provided by RealTraffic

-Auto Park: PSXT decides on its own which combination of RT Parked data and airport-file data should be used to achieve the configured Target % value. There is no documentation stating that all RT Parked aircraft will always be preserved.

If your goal is:

“All RT Parked aircraft should remain visible, and only the missing stands should be filled using airport-file data.”

then that would effectively be a third mode, which is not described in the current documentation.

For LGAV, I would therefore recommend:

• If real-world accuracy is your highest priority → RT Parked Only

• If a well-populated airport is more important → Auto Park

If Auto Park removes RT Parked aircraft even though sufficient parking stands are still available, that may be something Nico would want to review or refine.

The release notes do not explicitly state that Auto Park must always give priority to RT Parked aircraft. They only state that the various data sources are combined to achieve the configured Target % as effectively as possible.

Therefore, your expectation — “RT Parked Only plus airport-file aircraft added on top” — is perfectly understandable, but it does not appear to be exactly how the current Auto Park logic is implemented.

So Nico, do you think it would be possible to refine this function? Or is this too difficult to achieve?

Kind regards

Robert

That is a great suggestion. I found myself wondering the same thing yesterday when I first tried the Auto Park feature and then switched to RT Parked only. It made such a large difference in the way KDEN felt, that I had to turn Auto Park back on. Of course, I don't know if there is a "preference" already built into Auto Park that already takes the RT parked planes into account.

Hi guys,

With the Auto Park function enabled, PSXT starts with a Max Fit value of 0, then increases it to 0.5, and so on. At each iteration, it first searches in RT Parked, and then in the airport file.

However, once the requested number of aircraft has been reached, the search stops. As a result, some RT Parked aircraft with a higher (worse) fit value may not be taken into account because they are considered less relevant. Remember that RT Parked can also contain aircraft parked for 6, 10, or even 47 half-hour periods.

That is why, if you look closely, you may notice that the static fit is sometimes lower (better) than when using RT Parked only.

There may still be a bug in my code, and I will check that, but this behaviour is intentional. In fact, the same thing happens if you have Auto Park disabled and set Max Fit to 1.0. In that case, you may also miss some RT Parked aircraft.

I need to describe this behaviour more clearly in the manual, so that my AI Tutor can explain it properly too. :-)

Nico

EDIT: If you want to compare both settings, try starting PSXT, do not change any parameters, and then press Park. That will give you the most reliable comparison.

Hi Nico,

I`m going to try this.

I actually just checked the log file as well after missing some flights which should be there.

GATE A7 : no static parking for BAW630, static aircraft UAE3TK* is adjacent at GATE A9, possibly colliding

GATE A9 : no static parking for UAE3TK, static aircraft AIZ213* is adjacent at GATE A11, possibly colliding

Could this maybe be the reason why I see less traffic than expected, even if "Auto Park" works as intended?

Is there a way to change this behaviour, so that all aircraft show up?

Edited Saturday at 06:43 AM2 days by Robert_LH

Hi kiek,

as already mentioned in the above message, here is a full log text example.

Again there seems to be a conflict although the parking stands are wide enough and are used like this in real life too.

GATE A3 : no static parking for UAL124, static aircraft THY8FW* is adjacent at GATE A1, possibly colliding

GATE A9 : no static parking for DKH1657, static aircraft PGT1191* is adjacent at GATE A11, possibly colliding

GATE A3 : no static parking for UAL124, static aircraft THY8FW* is adjacent at GATE A1, possibly colliding

I think this maybe the reason for missing aircraft. It would be great if you could have a look into this.

Yes, probably with what you have done before editing the park_airport.xml
Change the radius of the stand to what it is in reality?

Edited/updated answer. See below :)

Edited Saturday at 03:10 PM2 days by Robert_LH

Nico,

I think I found the mistake with the radius. Some gates had a too wide radius.

I have edited it again and checked thouroughly and now the collision issue is solved.

I`m sending you the updated park_airport file again, if that is alright with you.

Sorry for the mix up.

Specifying smaller parking would make more sense as the larger aircraft will use it regardless of the size. One thing to keep in mind though that in all of your examples you are using a live aircraft and one from the archive from a previous week so they may interfere to some degree.

Maybe it could come down to which one gets the priority in the event of a gate "conflict" instead of just random. One would think that live or the most recent traffic would get priority, but I don't know if that's the case.

I think Robert is talking about static parking only.

He may be, but even mixing static parking from different time periods can result in conflicts. Plus his examples of conflicts all show a live vs one from the archive.

It's common for Gates to utilize different lines depending on the size or type and scheduling what is going to park beside it.
