Hi folks,
today I flew to Boston and the AFCAD file did a nasty game with me. From the 4 available runways I had only 1 choice to land ! Then I checked it and found some interesting things. Boston have 2 long and 2 shorter runways. Only 1 long is available to land, and the other is for takeoff

I guess that was the reason that it let me to land on the one 10000-er available, being a heavy aircraft, and would not let me to select any of the shorter ones.
Do you know any runway preference there ? I would program my AFCAD that way

Thanks in advance.
