Does anyone know if these AI planes from Project AI actually fly the whole route or they just disappear after a while?

Well, that depends on what you're doing :). All Ai traffic will only appear within a certain radius of your own posistion (I think it's a hundred miles or so). Furthermore, AI planes do not follow airways, they fly all routes direct. Also, they disregard en-route winds, i.e. their ground speed is always the same. So, if you take off behind a BA747 from Heathrow, and both of you are going to New York, you'll probably hear him all the way across the Atlantic, provided your route isn't too far off the direct route and winds aren't too strong.Cheers,Gosta.http://www.hifisim.com/images/as2betateam.jpg

ha!thats pretty cool as they fly the whole route.

The AI aircrafts' dissapearing acts are nothing to do with who produces them...it's an FS9 thing! I always thought that the radius for them to be existing 'physicaly' around you was 40 miles, which seems to be demonstrated by a couple of TCAS guages, however, the visibility range is certainly 10 miles.For example, I do a lot of flying from the UK, RAF Mildenhall, to varying airports around Europe to where the KC-135's fly and have on many occasions followed a KC, or an E3 Sentry Awacs at a distance of about 20 miles all the way (showing on TCAS)! One nice flight into Stavanger, Norway, I had an E3 in visual, aprox 2 miles, at 1 o'clock, 2000ft below me, for the whole flight as I'd followed him off the runway, and then followed him down also......all my AI are Project AI except for a couple of 'oddities'which PAI don't yet cover (ATA airlines L1011 for example).

yeh....I'm pretty sure it's a 40 mile radius. If you follow an AI plane in CTRL-W whilst leaving your aircraft at the airport you'll see it disappear about 40 miles out.

That's the way the CTRL-W appears to operate to me also. However, if you put your plane into slew mode in top-down view and are careful not to lose sight of the AI plane you can track them much farther.I don't know if there is a distance limit to this procedure as I'm not about to spend two hours following an AI, but I have tracked them for several hundred miles.

Clayton,If you are truly interested in the answers to these questions, search the library for TTools by Lee Swordy. Within his ReadMe files are superb and thorough explanations of exactly how the AI Aircraft are implemented in FS. It is truly amazing as to the true complexity and beauty of this "little" addition to FS.Happy flying,Bill Molony
