AFCAD Question

[Guest]

I am having a problem with AFCAD.I am trying to make a file for for the new scenery for EGLC, but am having problems with the taxiways. Although the runway has three links to the apron, departing and arriving aircraft are using the same one causing head to head jams when using 28. Is there a way to designate departing aircraft to one link and arrivials to one of the others?

Howdy:The problem is that AI will always take the shortest route to the gates or runways so you'll have to trick them, if possible.not sure if this will work...1. disconnect the eastern approach to the RW, by deleting the line between the hold-short node and the runway.2. from the hold-short node, run a short blue line towards the runway but don't connect it.3. disconnect the western end of you turnaround loop from the runway.4. run a blue taxiway line on the runway, parallel to it, from the eastern approach to the western end of your turn-around loop; this line can be very close to the runway line but don't connect the two.If this works, the A/C should taxi to takeoff via the eastern approach and leave the runway at the western end.Let us know how well it works, if at all.Also, I would reduce the number of nodes in the turnaround loop to prevent A/C "jiggle" and pull it towards the runway as close as possible. If a taxiing aircraft leaves the runway the tower will give clearance for other A/C. Another option is to widen the runway itself (e.g., to 250 feet) since it defines whether the A/C is on the RW or off.Finally, consider adding another blue node right behind (below) your hold-short node on the eastern taxiway to prevent AI waiting for takeoff from jamming up. Cheers, Holger

Thanks, I will give that a try now. Will let you know the result,Mick

Holger, you are a miracle worker. Job done and it works well. About 20 hours I have been working on this file. Thanks a million,Regards,Mick

Howdy Mick:thanks for the flowers - glad I could help.I happen to be interested in EGLC too as it is the home of one of the "heliports" for my AI choppers project, due to be out this weekend (here's my plug http://www.yoboworks.com/cgi-bin/ib3/ikonb...gi?act=SF;f=35). The choppers park and T/O in a bit of a ridiculous spot but EGLC is pretty small and I didn't want to interfere with the other AI.Anyway, I tried what I suggested and can report too that it works ;-)Two screen shots from testing are attached, as is my AFCAD for EGLC; all A/C are AI.Cheers, Holger http://forums.avsim.com/user_files/13167.jpghttp://forums.avsim.com/user_files/13168.jpg; Flight Simulator Airport EGLC (London City); File generated by AFCAD Version 1.4; HomeFile( "eurnwafd.bgl" );Set( fsvers 0x800 )Header( 1 N51:33.0522 N51:27.5317 E0:08.0571 W0:01.4929 )AI_Border( N51:33.0522 N51:27.5317 E0:08.0571 W0:01.4929 )Container( APT 1 ) APLocation( N51:30.3234 E0:02.7889 5.18 ) ICAO_ID( EGLC ) ;---- Runways and associated ILS units RwyLoc( N51:30.3162 E0:03.1997 5.18 92.890 -4.0 3634 250 N 10 CEMENT 0x52 304.8 ) Navaid( N51:30.2906 E0:04.0338 5.18 92.890 111.150 LOC NONE 2 "ILST" ) Navaid( N51:30.3527 E0:02.8455 5.18 5.500 111.150 SLOPE NONE 2 "ILST" ) Navaid( N51:30.3473 E0:03.2654 5.18 92.890 111.150 DME NONE 2 "ILST" ) Navaid( N51:30.3381 E0:02.5303 5.18 272.890 111.150 LOC NONE 4 "ILSR" ) Navaid( N51:30.3284 E0:03.6932 5.18 5.500 111.150 SLOPE NONE 4 "ILSR" ) Navaid( N51:30.3473 E0:03.2654 5.18 272.890 111.150 DME NONE 4 "ILSR" ) ;---- Marker Beacons (if any) ;---- Helipads (if any) ;---- Communications Frequency( 132.700 APCON "CITY" ) Frequency( 128.025 APCON "CITY" ) Frequency( 132.700 APCON "THAMES" ) Frequency( 118.075 CT "CITY" ) Frequency( 118.400 CT "CITY" ) ;---- Start Locations SetupLoc( N51:30.3300 E0:02.7890 5.18 92.9 1 N 10 ) SetupLoc( N51:30.3003 E0:03.7352 5.18 272.9 1 N 28 ) ;---- Control Tower Tower( N51:30.2312 E0:02.9799 21.64 0 ) ;---- Taxiway and Parking data AI_DataStart TaxiwayPoints( 0 -126.34 -74.31 0 166.16 -91.28 0 189.56 -92.61 0 1018.42 -35.43 0 112.75 6.05 0 -50.48 14.35 1 169.06 -45.88 1 -103.49 17.23 0 -124.27 18.41 0 1002.22 -64.90 0 984.68 -69.26 0 954.91 -36.94 0 968.44 -38.63 0 171.86 5.43 0 167.82 -60.26 0 200.07 -0.55 0 187.22 -103.56 0 25.01 -83.09 0 -13.74 -80.84 0 -54.25 -78.49 0 -87.26 -92.66 0 -86.40 -76.63 0 -123.84 -91.14 0 -126.04 -102.59 0 -89.77 -104.13 0 -54.90 -90.86 0 -14.41 -93.02 0 24.30 -95.54 0 123.66 -88.81 0 122.18 -97.82 0 -30.27 36.68 0 -9.68 41.28 0 9.32 11.31 0 270.10 -1.99 0 416.59 -9.46 0 554.63 -16.51 0 715.22 -24.71 ) Positions( -130.00 -123.27 14.00 190.1 0x00300381 -95.24 -129.17 14.00 190.1 0x00300401 -57.19 -134.72 14.00 183.1 0x00300401 -16.52 -131.15 18.00 183.1 0x00400381 22.13 -133.22 18.00 183.1 0x00400401 116.94 -129.73 31.00 189.7 0x0C80030A 181.93 -132.61 31.00 189.7 0x0C80038A ) TaxiwayPath( 1 29.9 500000 11 3 0 1.0 0 1 29.9 500000 32 4 0 1.0 0 1 29.9 500000 32 5 0 1.0 0 1 29.9 500000 33 4 0 1.0 0 1 29.9 500000 34 33 0 1.0 0 1 29.9 500000 35 34 0 1.0 0 1 29.9 500000 36 35 0 1.0 0 1 29.9 500000 36 11 0 1.0 0 2 30.5 500000 16 6 0 1.0 0 2 30.5 500000 23 0 0 1.0 0 2 30.5 500000 24 1 0 1.0 0 2 30.5 500000 25 2 0 1.0 0 2 30.5 500000 26 3 0 1.0 0 2 30.5 500000 27 4 0 1.0 0 2 30.5 500000 29 5 0 1.0 0 0 29.9 500000 5 7 0 1.0 0 0 30.5 500000 3 9 0 1.0 0 0 30.5 500000 9 10 0 1.0 0 0 30.5 500000 12 10 0 1.0 0 0 30.5 500000 13 6 0 1.0 0 0 29.9 500000 14 6 0 1.0 0 0 29.9 500000 14 1 0 1.0 0 0 30.5 500000 15 12 0 1.0 0 0 30.5 500000 15 13 0 1.0 0 0 30.5 500000 16 2 0 1.0 0 0 30.5 500000 18 17 0 1.0 0 0 30.5 500000 19 18 0 1.0 0 0 30.5 500000 21 19 0 1.0 0 0 30.5 500000 21 0 0 1.0 0 0 30.5 500000 20 21 0 1.0 0 0 30.5 500000 22 0 0 1.0 0 0 30.5 500000 23 22 0 1.0 0 0 30.5 500000 24 20 0 1.0 0 0 30.5 500000 25 19 0 1.0 0 0 30.5 500000 26 18 0 1.0 0 0 30.5 500000 27 17 0 1.0 0 0 30.5 500000 28 17 0 1.0 0 0 30.5 500000 29 28 0 1.0 0 0 30.5 500000 5 30 0 1.0 0 0 30.5 500000 30 31 0 1.0 0 0 30.5 500000 31 32 0 1.0 0 0 30.5 500000 2 1 0 1.0 0 0 30.5 500000 1 28 0 1.0 0 0 30.5 500000 7 8 0 1.0 0 0 30.5 500000 8 0 0 1.0 0 ) TaxiwayNames( " " ) AI_DataEndEndCNameList( 409 ) NameEntry( REGION 0 "Europe" ) NameEntry( COUNTRY 0 "United Kingdom" ) NameEntry( CITY 0 "London" ) NameEntry( AIRPORT 1 "London City" )EndNL

Me again:oops - posted an earlier version of EGLC. If you want to use the one listed above it's better to remove the turnaround loop at the western end and close RW direction 10 for landing. I hoped it would be possible to have both directions open but it doesn't work.Cheers, Holger
