LOL !! I think everybody knows how if your going to fast(seems to be the problem)ATC will zig zag vector you to your airport of choice. Here's one never came across till tonight while checking out Bill Melichar's new Licenciado Benito Juarez International Airport(MMMX) scenery. -Quite good if I may add. Anyway, was also checking out the new Mexico AI 2005 package in the library, as well as some AFCAD work I did for Bill's Scenery. I did a short hop down to Acapulco and back. On the flight back ist were I think ATC hit the bottle. Had a cruise FL210. ATC directs me to decend to FL18, then approaching FL18 I get the direction to decend to 16,000, no problem level out at 16,000 for a few minutes then directed to 15,000, as I approach 15,000 I get direction to climb to 16,000. This happens about 7 times back and forth between 15,000 and 16,000. Good thing I hadn't been drinking LOL. I all this I get vectored for ILS to 23L at 15,000 needing to decend to 8,700 to capture ILS. All at about no more than 10 miles out. So do the mad 2,000 FPM decent to capture ILS. But there's a good ole Mexicana F100 sitting on the runway, causing a go around. I then get directed to 11,000, I'm thinking not bad, as start setting up to get turned arounded for the approach. But ATC decides to I think start the 15 / 16 agian, but at the first direction to climb to 16,000 I bagged IFR and swung around for a visual to 23L. In all this, The Mexico AI 2005 & Bill Melichar's MMMX scenery are worth a look. ;) Both available here at the library.:-outtahttp://publish.hometown.aol.com/p3superb/i...s/sign_name.jpgichar's new There is a fine line between "hobby" and "mental illness".- unknown"My daddy gives me up, to fight for you"- a US Military Members Child

Seems pretty good for New Years. Probably lucky to get anyone in at all on the weekend in Mexico! I wonder sometimes if some of these ATC people aren't A.I. pilots putting in extra hours when you have the sliders to the left.

It is too many occurrances like that which make me switch to VFR flight most of the time. That way I can fly my own IFR approach and not worry about listening to the ATCs strange requests. Turn left heading 190... Turn right heading 210... turn left heading 190... etc.

Hello P3!How are you coming along with the MMMX Afcad you mentioned???? We desperately need one for Bill's MMMX scenery, which I agree with you, is the best MMMX we've had by far....and Yes!!!! You gotta stay ahead of the game with those FS2004 ATC folks because they can ruin your day very quickly if you don't watch it. Hopefully we'll see a better ATC engine with FS2006.Sincerely,Dennis D. Mullert

Dennis, Sent you an email, Its done pretty muuch I think as far as Gate / Parking placement, just need to figure out who uses what gates. Here's some screnies.

>Turn left heading 190... Turn right heading 210...>turn left heading 190... etc. I've been aware that this happened more frequently, as I added more traffic to FS9. Believe some or all of it may be vectoring to move you around slower moving aircraft. Don't recall it happening much in the C182RG, as I was flying at lower altitudes. Not using ATC as much. But, when I began flying in a B1900 especially in NE or upstate NY area, ran into it. Wonder if it is moving to avoid slower aircraft, anyone know?

It may also be a phenom cause by addon MESH, which is much more accurate than MS Mesh. IE MS mesh may be accurate to 150 meters, and a lot of the addon is accurate to 10 meters. Thus the FS is not expecting such sudden or drastic variations in the terrain.It is probably keeping aircraft a standard height above the land mass. Detects that the next mountain is also 1k shorter. So has you decend. But, then the one behind it is 1-2k higher, so must have you climb. As the landscape in the West and Mexico has LOTS of mountains, altitudes vary drastically, you go up and down. It would not happen, except you are on an approach, maybe a distance less than 25mi to the airfield. There are places in Wyoming, where this happens frequently, as the airfield is at 5-7k surrounded by mountains at 12-14k... Maybe it should have a different approach for these conditions, Circling 360deg to lose altitude... ;-) Bob
