Its introductory flight screening, your basically off to one of the local airports either in pcola (navy) or quantico area (Marines) to fly around in a cessna for just under 50 days. Its another screening process used by the Dept. of the Navy before they begin investing a lot of money in you down at API, Primary, etc to only have you fail out because you dont like the sensation of flying. You go to ground school at IFS, solo, i believe you also Xcountry but you dont get your private pilots license. You also take the FAA exam and once your done you head to pcola or you just report to api to start. Hope this helps..
