Hello,

Everything works (even tower during ILS). Im using Active sky 2012 and Ultimate traffic 2. Traffic density is set at 60%. FSX default traffic is off.
During most flights im assigned at a landing runway while AI traffic takes off at the other end. Just had a flight from EDDL to LSZH. I was cleared on runway 16 while i had 12 knots wind from 192. I was heading towards a plane taking of from runway 34...not really a reflection of real life ;)

How do you solve this?

Greetz, Boby

Just flew from LSZH (Zurich) to EDDL (Duesseldorf). My taxi holding point was rw 14 while other aircraft were taking off at rw 28.
Reaching the holding point, taxi gauge gave this message, i set the parking brake to wait for the tower. Nothing happened.
I was frustrated so i just took off, PFE still running in de background only warning me for AI traffic. I listened to the EDDL atis during descend and the active rw was 5L.
Wind was coming from 280.

Before PFE i flew with the FSX ATC. This ATC always used AI active runways except complicated airports like EHAM or in this case LSZH. And if not it would always take care of the fact that i would not land in the direction of taking off airplanes. Please let me know if im doing something wrong or that this is a bug in the PFE software. Maybe its the problem with Ultimate Traffic 2?

Gr. Boby

PFE always checks to see which runway ai traffic are using and then uses the same. If, at the time of checking, there are no runway assignments currently active it will choose the CORRECT runway according to wind direction. If you have little or no surface wind at all then FS usually gets it wrong.

Just a thought....do any of your AFCADS have closed runways?

No, i have airport design installed but i never got to the point to close certain runways. I use Actice Sky 2012 real time weather. I have also checked the options for AC 2012. Im using dynamic weather control mode together with ATC wind lock activated.


- Create a flightplan in FS Commander 9.3
- Save the plan to PMDG and FSX
- Load the flightplan into AS2012
- Converting in PF2000 and selecting the plan in PFE
- Start FSX
- Activate PFE
- Start flight

These are the steps i perform every single time.

Can't help I am afraid. I use FS9 with Active Sky Evolution. I have never had what you are experiencing. I occasionally get notified of a runway assignment, and then get notified of a runway change, but always in good time.

As Dave said, PFE will use the runway that FSX AI traffic are using, unless there is no AI when it will choose. If before you land some AI are active and will use a different runway, then I think PFE will change the runway assignment. Are you switching to Tower frequency too early perhaps, so you dont hear the change of runway assignment ?

After ground give you clearance to taxi to runway X, you can request a different runway. If Taxi Guidance System has already activated, press 1 to deactivate it. Now use Ctrl+Shift+W to select another runway. PFE will list the runways at the airport one by one, and you press N to go to the next one on the list, or Y to accept one. Once you have your clearance to taxi to the new runway, the Taxi Guidance System will reactivate itself.

Actually, i dont have so much trouble with the take off runways. Its more about the landings. Hopefully you do not see this a a troll. Im loving PFE, the voices, push and start, taxi guidance its a very complete ATC program and i regret i did not bought this earlier. BUt somwhow i feel there is a problem concerning runway assignement which i did not excounter using FSX ATC.

Most of the flights i fly with PFE just before descend i aks the ACARS ATIS report for the destination airport. I read that runway "x" is active for landing and departing. I accept and i enter ILS. While being on ILS my traffic alert goes bezerk cause there is traffic departing from the opposite side. I see landing lights coming straight at me.
Without PFE i have never saw this happening. (except for EHAM, which i do have the scenery but i never use it cause of the rare layout). I only fly airports with paralel runways.

Ill do a test. I will fly 2 flights with a historical weather point at a certain date at the exact same time.
I use Ultimate traffic 2 so flying both flights at the exact same time should give me the same AI flights.
Ill fly EDDT - LSZH (both Aerosoft airports). One flight with active PFE and one flight without PFE relying (as far as that is possible) on FSX ATC.

See how they assign and how the AI behaves. Ill get back with results.

When you use ACARS/ATIS to get your arrival runway, it bases its information on the weather report it has at the time.

However as you get closer to the airport the weather will likely update/change. You should not be basing your arrival runway on what ACARS/ATIS say, but on what PFE ATC tells you. What runway do they assign to you ?

At some point on approach you will be told to "fly heading X and expect vectors to runway Y". At that point you can use Ctrl+Shift+W to request a different runway. If you are flying a STAR and don't get the "fly heading X and expect vectors to runway Y" instruction, well, I'm not sure about that one. There's probably some point, though, at which you can request a different runway. If all else fails you can request "clearance to final at pilots discretion" and land at whatever runway you want. Bottom line is you're the pilot and can override atc instructions if you feel they would create an unsafe situation.
