Does anyone know how to make AI aircraft landing roll-outs more realistic,they stop almost as quickly as a F1 car instead of rolling along the r/w.

Thanks

There is a file which makes the AI taxi at any desired rate. As for your problem, I am not familiar with any utility desgined to do this. FS AI isn't exactly intelligent. The things don't even use reversers.

Me neither. Most of the time it takes them ages to leave the runway after they landed.

Alan,

Hum........  I have noticed the "short stops" too.

And yes it takes them a long time to exit... but NOT a long time to stop the roll out.   

I wonder if you changed the brakes effectiveness in the aircraft.cfg file for the AI planes (assuming that you use separate AI aircraft) if that would slow down their braking?

best,

.................john

Thanks to those that replied to my query.

To John Baymore, yes I tried altering the brake effectivness but it made no difference. I don't know how far your planes go down the r/w before starting taxi-in,mine go about a 3rd of the way.
I'm wondering about the reverse thrust,I think I'll give that a try next.

Thanks

Hi John, regarding my previous message, stupid of me bevause it happens with props as well as jets so it can't be the reverse thrust.
I have noticed that when watching a landing with Traffic Tools that it shows 'landing' even after the plane has touched down & it is not until the plane has almost stopped that it shows 'roll-out' & that is only for about a second or two,then it changes to 'taxi-in'. This seems to indicate that it is inbuilt in FS9 & not something that can be changed.
Where does 'roll-out' begin & end in the real world? Is it immediately at touch-down ?

There's an awful lot of uninformed and unjustified criticism about AI and the above is an example. They DO use reversers - if they are available.

...

...

This is Mike Stone's Airbus as AI

I have adjusted almost everything to do with AI at some time or another. I've got many different types of aircraft and helis flying (single and twin rotor) from land and carrier decks and I'm pretty sure if you can get aircraft to stop on very short runways as I did for someone (sorry - forget their username name) you can do it the other way round.

IMO AI is one of the BEST features of FS2004 (and FS2002 before it). It adds immeasurably to the realism and enjoyment of FS and like the above, most of the criticism is totally unjustified from people who have not taken the trouble to find out what is and what isn't. Like most good things about this sim - whether it's aircraft and scenery design, even just tweaking FDEs, getting results takes time and effort. Most people aren't prepared to put that in.

Sorry Woozy it's not aimed personally at you, but your sort of comment gets passed on and picked up by newcomers.

Roller,

Do you have a suggestion to fix the "instant stops" for Merv?  I just accept it as an annoyance  Wink.


best,

..............john

Can't say as I've notice the problem myself and I have spent a lot of time watching AI land because of the amount of work I've done with it. Then again, I have very few default aircraft working as AI - no heavies except for some BA 747 repaints I did using the default, only the default GA planes.

My heavies are mainly PAI - and I had a problem getting a PAI Airbus to actually stop in time in my EGBX STOLport.

To start looking at a problem like this you have to use some general aerodynamic principles.

1 - The plane is probably approaching too slowly if it pulls up very quickly. How do you reduce airspeed on approach  Wink you've got it - so try reducing the flap lift

2 - It's being retarded too quickly - try reducing the flap drag because remember that AI planes always use full flap. Also try reducing the spoiler drag.

3 - You might also want to look at the drag figures

It's always a good idea to start with an FDE from a similar default aircraft when making these kinds of changes. One little secret I'll pass on is - play with the autopilot and flight dynamics section in the air file. Try swapping them around into other aircraft. You'll be amazed at how differently aircraft perform with different bits in their air files. And remember - this is an art not a science. Don't be tempted into thinking that MS have simulated REAL flying models. They haven't. Plugging 'real' numbers in WILL NOT give you real results no matter what people like POSKY try to tell you  Wink

There's no way that ALL AI aircraft are coming to a dead stop - least not in my experience. When I get some more time I'll look a bit more but watching my AI Concordes, DC3s, AN124s, Airbuses, Mustangs, Trislanders, Cessna 310s, Navajos etc etc let alone helis like my Huey (that does because it has skids), Hawks, Westland Whirlwinds, Merlins, S61s, Pavelows, Eurocopter AS332s, CH46s and 47s etc is one of my big pleasures in the sim. And it actually took me ages to get my Hawkeye, A6, Tomcat, Phantoms, F14, F16, F18, Cutlass etc to stop really short on carriers the way I wanted them to.

I just don't think the 'urgency' to get off the active that is instilled in real pilots is there in the AI, and that seems like it'd be hard coded to me.

Of course it isn't - these aren't real pilots you know  Wink

The way the AI seems to work is that it has to come to a dead stop before take off. If you put in too much engine power and the braking can't stop it, the aircraft (helis included) just creep down the runway and never take off.

Also, AI cannot turn off the runway after landing until speed has been reduced to the normal taxi speed. Some, but not all aircraft in my experience, come to a stop and then restart. It will pass all the turn offs until its speed is sufficiently reduced and will then take the next one however near or far that is. It won't turn round and go back to turnoff it has just passed. And it won't speed up especially either the way a real pilot would - it just carries on taxying along the runway at the normal taxi speed.

From what i have learned from watching AI, once they are on the ground and have come to a complete stop, that is when they radio ground to taxi to the gates. Once the ATC has started to respond to the AI that is when they move off the runway.

If you make it take longer for them to stop, your adding extra time before they will clear the runway and that will cause planes to be radioed to go around.

When offline I fly with a ton of AI and go arounds are already annoying as it is. Prolonging their runway time will cause lots more confusion.

No, they are instructed by Tower to contact Ground as soon as they turn off the runway. They come to a complete halt to do that but they are clear of the runway and will not cause a go-around.
