This is an update of the Hawthorne AAF that I created back in 2018 for FSX to complement the GAS PT-13 Stearman. I tested it and it seemed to work fine on my Windows 10 in Prepar3D V4.5 including the ai flight plans. Let me know if you have any problems so that I can fix them. Thank you. Enjoy. This came about from a request from Momo81 a few days ago. You can download the GAS Stearman PT13/PT17 package here in the Resources.
