FSX. Well looks like you all are really enjoying ATL v3. From what I understand, sales are good! There's an update for KATL 2016 FSX. It adds the red hold-point pavement signs that were strangely left out of the release version, and a fix for the handful of you that have reported seeing the default ATL tower popping up. Download via the source link. P3Dv3 optimized version coming soon.
