I was tinkering around with the AFCAD last night, and when I finished around 1am, I was just too tired to write...
So here's my playing around with the runway:
I wanted to get to the following result:
- Takeoffs from both runway 28 and 16
- Heavies (767s and bigger) to use only runway 16
- All others (321 and smaller) to use a mix of 16 and 28 (I understand that it is not possible to have them use only 28(
So I played around with runway length of 28 a bit. The runway length in your file (1950 meters) didn't give me any Airbusses on 28, so I made it longer. I played around with many many combinations (re-started FS around 40 times), and I now settled for a runway length of 2130 meters. This gives me all heavies on runway 16, and a mixed of use of 16 and 28 of all other planes. The only plane that bothered me was the A321: when I put runway length to 2140 meters, some of the A321s take off from runway 28 - but then so do the B767s, B777s, A330s and A340s. Not acceptable! So I reduce it to 2130 meters, which makes all the B767s and above use runway 16 - but then no A321s on runway 28. I conclude that the A321 are in the same "weight league" as the B767s and bigger, so wherever the A321s go, the heavies go as well. I therefore settled for a situation where A321s all take off from runway 16. Which is OK, given that Swiss has only five or so A321s, so no big deal.
As for landings, I did something else - which works for me, but maybe not for the "general public" whom I know you want to cater to.
I basically play around with runway openings depending on time of day I am operating in and out of Zurich. For most times of the day, the situation is:
Landings: runway 14 -> so I open runway 14/32 for landings only
Take offs: runways 16 and 28 -> so I open runways 16/34 and 28/10 for take offs only
The behaviour I am getting is very close to reality and I am very pleased with it.
In the evenings after 8pm, the situation is a bit different:
Landings: runway 28 -> so I open runway 28/10 for landings only
Take offs: runways 32 and 34 -> I opened them for take offs, but so far take offs go from 16 instead of 34. But I'll play with that tonight in my next testing session.
The behaviour I get: all planes that land in the evening are A320 and smaller, and they all land on runway 28. The only plane bigger than that in the evening is an Emirates A330 - which landed on runway 14. Great! I can live with that.
So my only problem left is how to create the "evening" situation, i.e. take offs from runways 32 and 34 instead of 16. But I think to have that it is not enough to simply open/close runways (which can be done in seconds). The order/labelling of runways has to be changed, which means I need to create a separate AFCAD file. Again, I am not a runway specialist, so I'll try and test. If it doesn't work, I'll stick to the "day" situation at all times.
Let me say again that you have done a superb job on the runway system. How you managed to get the combinations of 14,16 and 28 to work is simply amazing. Thanks a lot for that!
