Runway objects - No Primary Landing

Hi, The following options for runway objects don’t work to me No Primary
Landing No Primary Takeoff No Secondary Landing No Secondary Takeoff Had no
luck in several attempts with different runway size settings even with
extremely short runway, ATC does not respect it. Also noted that ATC uses any
runway for AI traffic regardless its physical dimensions. Could you clarify
current functionality of these options, because I suspect that they’re left as
legacy support thanks

Hello. These options are used on runways like EDDF 36 that are closed in
reality. This threshold exist in the game but we use these options to disable
its use by ATC. That said, this is used to compute a weight and if the wind
configuration makes it so that this flagged threshold is the only usable one,
ATC will bypass those flags. This will not be a problem on airports like EDDF
where an alternative will always be found but will occur if you have a single
runway. About AI Traffic, what kind of traffic are you using in game? Real-
time ? Offline ? SimConnect controlled ? Regards, Sylvain

Hi Sylvain, I use real-time AI traffic, due to lack of auto generated offline
traffic at test airport, but I mostly care about user-flyable plane, because
the main idea to have separate RWY with only one working threshold for STOL
traffic within existing airport structure. In my test project with 2 main
crossing RWYs, I’ve added 3rd very short RWY with only one working threshold(
using options above), taxiway and parking spot which are separated from main
taxiway network. It works OK so far despite the ATC completely ignoring the
restriction flags. Anyway, thanks for pointing me out EDDF, I’ll look into it

Hello. Real time traffic will not take this kind of restrictions into account,
this type of traffic relies on real traffic data and we don’t filter it based
on airport restrictions. If the runway you’re talking about is completely
separated and has its own parking spots and taxiways, I expect the same
behaviour will occur. ATC will try to avoid using this runway but if the wind
is blowing in the opposite direction, it will always prioritize this over the
“No Takeoff/Landing” flags. As an alternative, have you tried removing the
runway start in your runway properties? Regards, Sylvain

hi, thanks for info about AI traffic differences, it makes sense and not
mentioned in SDK docs. As for runway start positions, in my tests AI planes do
not take them into account for takeoff. There’s some sort of internal hard
coded logic for AI takeoff roll best

@Nocturne will have a look and see if the doc can be improved on this. About
the traffic ignoring runways with removed start position, are we still talking
about real-time traffic ? If so, as I said, the real time traffic comes from
real time data and is independent of any scenery configuration.

This has probably been updated since then, but when I fixed up ENZV a year ago
I had an issue of the sim not respecting those flags. My solution was to edit
the xml file so runway 18/36 was listed before 11/29 in the xml. That caused
the atc to prioritise 18/36. Might be worth a try.

The don’t work for me either. My Airport has 2 runway and one it’s just for
smaller planes but the ATC even if I have an airbus a320 they lead me to this
small runway. What can we do?

Hello. Your parking spot is linked to the bigger runway and still ATC sends
you to the flagged runway? If you upload your package sources, I can check it.
Regards, Sylvain


The two runway are disconnected… I could upload it but it’s 6gb so if you
can figure it out from here it’s better… Let me know!

Would be still available to check it?

That’s an issue. The ATC system computes some kind of weight depending on the
runway options, parameters, wind, etc… The runway length is very important
in the calculus so I would expect your longer runway to be selected, even with
wind matching the smaller runway axis. Can you tell me where this airport is
located and what wind conditions you’re using so I can run some tests?
Regards, Sylvain

The Airport callsign is LIME, those two runway are completely separated with a
fence around the airport and there is no way to connect them (The airport ICAO
it’s still one), I didn’t take into account the wind while trying the ATC, but
I guess it is irrelevant in this case since the Runways can’t be connected
there will be always a case where the 12 or 30 is chosen!

Hello. I’ve created a very basic LIME airport with just the 2 runways and a
tower but I don’t have the issue. When flying an A320, ATC always proposes a
10/28 landing, even when the wind matches the smaller runway axis. Can you
provide a link to your package in a private comment so I can test it in case
there’s some other factor playing a role here? Regards, Sylvain

Hi guys, I have been facing a similar issue. for the past 6 months I’ve been
developing Canberra Airport (YSCB) in which I avoided the issue at first but
now comes the time to attempt to fix it. In the default sim’s version of YSCB,
AI traffic use Runway 35-17 to TO/DEP however in mine ATC is only giving 30-12
to the traffic meaning that they’re landing on the incorrect runway. I used
Airport Design Editor (ADE) to take the AI config from the default and the
settings match mine, therefore I am led to believe that the problem is
elsewhere. I tried the solution listed above by Wombii in regard to moving the
runway in the XML to be before the other but unfortunately I am still facing
this issue. Would appreciate any assistance on the topic. Cheers, Josh -
