Maybe I'm not looking in the right place for my answer, but...Does anyone know how to get AI aircraft to complete a runway rollout after landing and exit at a desired taxiway without adding unrealistic displaced thresholds, or shortening the length of said runway?I have read in forums about tweaking the braking in the AI aircraft cfg file so the aircraft doesn't slow so quickly after landing, but I'm not comfortable enough with that process, and would likely make a mess trying to change aircraft cfg files.Thanks TONS in advance for anyone with some helpful insight!

Have you seen this?http://www.alpha-india.net/forums/index.php?topic=4339.0read through that and the linked table:http://janswebsites.110mb.com/flightsim/ai...e-settings.htmlI don't mess with it myself, but just looking through the table it looks like if you go to the Flaps.0 section of the aircraft.cfg and adjust the flaps settings you can influence landing point and stopping distance quite a bit, due to higher touchdown speed. Though this will tie up the runway for a longer time (until main gear exit the runway texture) I believe. Back up your aircraft.cfg and have at it.Another approach is to disconnect the taxiway link from the runway link so the AI passes it. that can really result in a long slow taxi by the AI on the runway, so be careful with it. I was toying with doing this on a couple airports I was working on, but decided against it. In one case most AI would exit at a high speed taxiway indended for the opposite end (needing a 140 degree turn) when the next exit was a high speed taxiway in the intended direction, but in the end I decided to leave alone to avoid long runway taxi time, besides the problem of what to do when the winds cause the other end to be active. scott s..

I discovered a problem with disconnected taxiways at MCAS Yuma where the AI aircraft came to an immediate stop after landing and performed a u-turn on and off the surface of the runway just to get back to the nearest available taxi link. It was bizarre and I wished I had recorded the event. So after observing this I discovered that there were a couple of disconnected taxiways in the AFCAD. This probably influences other AI behavior on the ground that I'm not aware of. Fun Stuff!

Thanks for the links scott, I will definitely check them out, and maybe get brave enough to backup and modify the aircraft cfg file(s). I'm building a test airport in the vicinity of Seal Beach/Sunset Beach, CA, based loosely on the LAX Master Plan-Alternative D, and it would just be really cool if I could get the AI aircraft to roll past the reverse high-speed exits and use the ones further down the runway as intended. I haven't experimented with disconnected taxi nodes yet, but I have noticed at other airports, ai aircraft doing U-turns and exiting the runway at the nearest exit/node to where they stopped their landing roll, rather than continue on down the runway to the next exit.-john

Is that the old Seal Beach airport near the Colony and Bolsa Chica?Mark

Hi Mark,My airport is strictly fictional of course, mostly testing runway/taxiway design, but the west end of the runways are under the approach for Long Beach, and almost directly south of Los Alamitos AAF. I call it Gateway-Los Angeles Int'l. I think the AI pilots and controllers get confused and say "Gainesville" sometimes instead of "Gateway", but I picked the name because it's not used in SoCal. N33* 44.2788' W118* 2.1585'.I used to use the site of Los Alamitos AAF, but even with my exclusions, FSNavigator shows the default Los Alamitos runways superimposed over/under mine.

What kind of planes are you using for AI that you are having trouble with. User planes do not make good AI, with out altering things(and even then there can be problems. WOAI and AIarrdvark and others (and default planes), planes made for AI, work best. Plus it is a bit of and art form to design runways and taxiways and parking, to get planes to do what you want.Bob

I think there are ways to get around that, maybe disconnecting the runway link. In FSX there is a "demo" default airport , EDDF, which does something interesting by stacking a second runway 26L/08R under the "real" runway 07R/25L. But I haven't studied these methods enough beyond knowing they exist. Some of these are used to implement the "plumbing" method of forcing separate inbound/outbound taxi routes. scott s..

Hi Bob,To start I use Just Flight Traffic (...because that's what I'm familiar with, and haven't messed with any other payware much except Ultimate Traffic, and even tried FSLiveTraffic), and then replace some of the domestic stuff by plugging in WOAI or PAI aircraft, as the visual models look better in my opinion.Tell me about it! Designing airports that have a good flow of traffic without bottlenecks at taxiway intersections and such is definitely a challenge, but I find it to be fun and sometimes even a stress reliever! There are times at work that I can't wait to get home to try an idea that's popped into my head.I appreciate the advice i've received in this forum, and will definitely include some of the suggestions in my future endeavors.When I design a 4-parallel runway airport like LAX, I reverse the runway use, that is I use the inboard runways for landing and the outer ones for takeoffs... generally making the landing runways around 8500ft and the takeoff runways 10500ft, and making the taxiways "end-around". This makes for an easier flow of traffic to and from the runways. The fun part is in designing airports like ORD, with lots of crosswind runways! It kind of splits up the arriving traffic so they're not all bunching up on the approach to one or two arrival runways.

Not to mention a bit of witchcraft.Joe

Sometimes I have AI aircraft do an abrupt stop at a high speed exit without completely clearing the runway... can't figure out why they don't continue to the hold short line and then stop for their "taxi to the gate" call. Sometimes I have so much comm traffic that the planes clearing the runway can't get a word in edgewise to make their call to taxi to the gate. I suppose it's a matter of sliding the traffic % down a bit, but I like busy, so I guess I pay the price. I'll have to keep working on it until I can find a happy medium.I haven't found anyone in the forums that have an answer for everything, and everyone's preferences are different, so I guess the neverending process of research and experimentation continues! :(

You will notice that big airports have more than one tower and ground freq. I wonder if that would help. If you have a few particular planes that don't land as you like, I would consider not using them.Bob
