I have 2 overlays for London, one for BA and one for all the other airlines. However, when a BMI or any other plane lands, it goes straight to BA parking slots, even if I move the reference point. Could the problem be both overlays share the same frequencies?

No. However, they must use different runways for this to work, and parallel runways work best. Move the reference point to the center of the runways for parallel ones, and closer to where each overlay contacts Ground after landing for the others (can be tricky).Hope this helps,--Tom GibsonCal Classic Propliner Page: http://www.calclassic.comFreeflight Design Shop: http://www.freeflightdesign.comDrop by! ___x_x_(")_x_x___

Tom's right about the positioning of the reference points, and the center of the runway is a good starting point, particularly for parallel runways.Another possible problem -You need to assign the aircraft for the new overlay using Traffic Tools or AITM. For example, all the BA planes still go to EGLL, but the rest should go to 2GLL, or whatever you named the overlay in AFCAD.Frequencies have nothing to do with this, by the way. However, you have to change the name on the ATIS frequency to match the overlay, or the ATIS option won't show if you start there yourself.

I switched all BA flights to EGL2 using AITM and positioned the reference points at the center of the runway. I will try playing with the points first.

You say you positioned the reference points to the center of the runway. Are you using the same runway for both overlays? If so, this will rarely if ever work. You need to assign a different runway to each overlay.Hope this helps,--Tom GibsonCal Classic Propliner Page: http://www.calclassic.comFreeflight Design Shop: http://www.freeflightdesign.comDrop by! ___x_x_(")_x_x___

No, BA uses 9R while all the others use 9L.
