Hello,

I am experiencing regular conflicts with AI traffic.

I have installed FSX, Active Sky 2012 and My Traffic 2013.

It happens quite often, that I get a take-off runway assigned which none of the AI aircraft uses. In contrary, they often use the same runway but the opposite direction than me.

The same appears regularly for the approach. The other AI aircrafts get the opposite direction assigned than me.

What could be the reason for that and how could this issue be resolved?

 

Any advice is really appreciated.

 

Best regards,

Tilo

make sure you are using the current version of FSUIPC4 from:

http://forum.simflight.com/topic/66139-updated-modules/

as it handles some of the limiting factors of ASE and I assume AS 2012 with restrictions under FSX simconnect.

 

The early pinned post regarding ASE explains some of the restrictions.

 

One thing I noticed is that My Traffic 2013 installs afd (afcad type) scenery files to adjust parking slots. Be sure those do not conflict with add-on scenery. You should also do a scenery rebuild from within RC (use the latest version of makerwys.exe from http://forum.simflight.com/topic/66136-useful-additional-programs/ before rebuilding) so RC has the correct runway position data.

 

RC first looks at any ai patterns established when it assigns runways. If none are present then RC uses the runway (length and navaid) and wind properties to select the best choice. If ai are using runways RC will pick that. If ai arrive after the runway assignment for departure or the ai change pattern due to late AS weather writes and ai refresh that may get things out of sync.

 

Before starting RC load up your parked aircraft, start AS and load the weathe. Then do an ai refresh after AS writes its weather to FS. Load RC and get it ready to go but do not start it yet. While you are prepping your aircraft the ai patterns should stabilize. The click START in RC, get your CD. When you contact ground by then the ai should be stable as affected by weather.

 

Approach is a different matter. I assume AS 2012 still under FSX must use Global Weather mode when using DWC. Global mode means in the FS universe all weather is duplicated from the environment at your weather location. This applies to your destination as well. ATIS will give you the expected weather based on the METAR but that may not be the case of the weather occurring at destination which is based on your aircraft location. RC looks at ai when you are about 40 nm out from destination when approach assigns your runway and again later. The problem is the destination weather is constantly changing as your aircraft location changes which can affect ai pattern stability. Therefore when you get very near the airport the ai may be performing differently then the RC assigned runway selection.

 

Check the "unofficial" hifi-sim forum here on AVSIM regarding these problems.

 

To get ai stability I recommend you use archived weather for the date Z time of your flight downloaded from hi-fi- sim's servers as opposed to real world weather downloaded in real time. Take advantage of the destination weather lock in AS if offered in the 2012 version. (This is recommended by one of the RC betas testers who worked along with Pete Dowson, the developer of FSUIPC4 who in turn worked along with hi-fi sim, the developers of the AS products.)

This should stabilize ai just before ai is checked by RC approach and keep the patterns constant.

 

This problem is not observed with FS9 AS products as global weather is not normally required as AS then uses FSUIPC weather smoothing.

Hello Ronzie,

thanks for the advice. I will check it out and let you know whether it helped.

Ron is exactly right.

 

Both Refresh AI and the Destination Weather Lock in AS 2012 and ASE are key to making sure AI uses the correct runways.

I agree. I changed the AS2012 settings to keep the destination wheather and now it works perfectly.

Thanks for your help here
