Hi,I have seen that there were some postings on the parking size required by AI aircraft. Therefore I did a systematic testing by setting up a test gate and different planes taking off from that gate. What I found is that the radius is important, not the descriptor small, medium or large or Gate versus Ramp GA. So you can set up the size range with a meaningful decriptor depending on the airport, thus making the selection easier when calling up the airport.I have tested the following planes and found these minimum radiuses required to be parked at such a gate. 1 foot less and it will not show up:MS B747 155 ftMS B777 151 ftMS B737 73 ftMS MD83 79 ftMS Dash8 50 ftPosky A330-200 125 ftPosky B767-300 101 ftStone RJ85/100 73 ftStone BAe146-200 73 ftPSS A319/320/321 63 ftComments:My observations are identical on the stock planes as stated in the documentation by Lee Swordy for his fantastic AFCAD, except for the B777 which could be a typing mistake (1 vs. 7)If you want to do testing yourself, MSFS reloads a change in size of a parking only after you have slightly moved it in addition to the size change and then saved. You dont have to exit MSFS and can run in parallel AFCAD. The reindexing is not important for the test.If you put your departing planes timewise from large to small sequence (i.e. 5 min) you can just set the time in MSFS different and the AI will be reloaded after a time change. MSFS allows a little delay of departure (approx. 10 min), before it switches to the next one in sequence. By that you can check that all planes show up correctly.The fact that the Mike Stone BAe has the same minimum requirement as the B737, made me check on the air file, and it is the same. Changing span in the air file or aircraft.cfg does not help. The data for parking space requirement must be hidden in some other variable.My experiment also confirmed the sequence of filling gates at the airport. Planes in time sequense look for the smallest gates that fits and is highest on the parking list.Hope this helps for those designing AI airport layouts. Maybe someone else can check on some other good AI planes to compile the list further.If you have questions on my test, you may contact me on [email protected] regards, Alexander

Good post, thanks. Testing described in the TTools forum has placed the location of the wingspan used for AI parking in the MDL file.Hope this helps,-- Tom GibsonCalifornia Classic Propliners: http://members.aol.com/tgfltsim/index.htmlAlcoHauler Locomotive Page: http://members.aol.com/alcohauler/home/alcohaul.htmlFreeflight Design Shop: http://www.freeflightdesign.com/ San Diego Model RR Museum: http://www.sdmodelrailroadm.com/Drop by! ___x_x_(")_x_x___
