Hey George is it possible to modify your KBOS AFCAD where at all times planes would only depart on 4L, and Land and Depart on 4R/ 15R. The added option of choosing takeoffs on RWY 9. This AFcad was done before on your previous Boston 2 freeware release. It works out really great and 24/7 365 the AFCAD remains the same. All The Best.
