AFCAD for KSEA

alba99 · Post by **alba99** » Sun Aug 21, 2005 3:32 pm

Great scenery, almost makes me home-sick, well second homesick, worked in Seattle for four years. Like the auto rental wash area, nice touch. Only problem is a log jam when you start up the scenery .

Anyone got a good afcad that handles the volume of traffic.

Seattle's layout is a real challenge for MSFS AI. Dual taxiways merging into a single taxiway, parallel runways, it was a nightmare to get it as good as it is.

We tried many popular afcad techniques to improve the flow. The one we have is about as good as it can get with the current AI.

If anyone can make a better one; sign me up

I do have an un-realistic afcad created by AI-Aardvark's Boback Shahsafdari.
This version removes all the taxiway paths between the runways & forces the arrivals to only cross at the rwy ends via taxiway T. Again, it’s completely unrealistic, but it handles dense traffic better.

If there is any interest in this, I'll upload it soon.

Yeah, I'd like to follow up on what George said. KSEA is tricky and if its a question of realism vs traffic density. The AFCAD was designed for realism.

Not sure how the AFCAD is setup, but Seattle Departs on 16L/34R and Arrives on 16R/34L Always

I hope they've implimented this, in the scenery. as the Default KSEA departs and arrives on both runways.

Looks Amazing! Thanks FlyTampa.

Hey Paul,

It is setup for 34R/16L departures & 34R/16R arrivals. If I opened both rwys for arrivals, its wasn't pretty

Kwsqd worked on the AFCAD. Thanks again Ken.

That's not true. At night they often go down to only one runway for both arrivals and departures so they can do maintenance on the runways. Also, when traffic flow gets backed up, they will sometimes use both runways for arrivals, staggering the planes about 1/4 mile apart. They've also been known to use 34L/16R for departures when there is need for the longer runways when landing, such as on rainy days when the heavy arrivals need more runway length to stop. Besides, 16R/34L is Cat I only, where as 16L/34R has the Cat III equipment, so when its really foggy, they have to land on the inner runway.

The usual traffic flow is arrivals on 16R/34L and departures on 16L/34R, but its far from always that way.

Nick, your absolutely right, I must have had a brain fart when I wrote Always, should have wrote Generally.

anyone else here having a hold short issue. whent he traffic lands at SEA they hold short, at the wrong node, they are holding at the one closer to 16 L than 16 R causing a mess with the fire crews!

shouldnt' they go to the hold short nearest 16R then wait ?

" as my mind remebers my training " dash across the line your fine"
FYI SEA FS GENISIS PAI FULL LOAD at 89 %

Hi there

Just did a short flight to take in this fab scenery. The problem I had was that it took 5 go-arounds before I was able to land then the wind changed and was landing against the flow. I also noticed that there were 3 aircraft that had landed and could not progress across the active because of the No. of aircraft waiting to take off. Does FS give priority to departing traffic?

Ther is a util that can increase AI taxispeed & help keep up roll out speed on the runway.

Thread about AI taxispped here:

I've been using it & it sure does help get the AI in & out faster.

Geroge,
I have that and am using, it but it still doesn't fix the "hold issue" does make them get there faster but they still hold at the first hold short line (nearest to 16 L)

I don't quite understand what you mean.

you mean aircraft holding after landing 16R & waiting for departures to clear 16L?

RegentAir · Post by **RegentAir** » Mon Aug 22, 2005 12:55 pm

I have the perfect thing to show you for this but no where to host it. so I will see if I can attach it for you, a simple image showing the problem

First let me say I've been sayign 16 but I have been wrong, when I pay attention to what I'm doing its 34L and 34R
here is the image to show what I mean attached
the SWA bird here has cleared the RWy but is holding at the 1st hold short, should he not go thru that one and hold at the one closest to 34R?

Post by **george[flytampa]** » Mon Aug 22, 2005 2:05 pm

Yes he should move further forward. If you listen to the ATC, you'll notice he's not even contacted ground yet. The reason they hold so short is because he can see the departures on 34R. If 34R was clear, he would hold much deeper. Unfortunately, I don't think it can be improved. We did try removing the holding nodes for 34R, allowing aircraft to cross 34R without clearance, but this method messed up landing on 16.
