Hey I am a 400 hour CFI ASE,AME,Commercial, and a 3/c Midn in NROTC. As far as the PPL goes it can't hurt, due to a medical reason, rotc is putting me on an LOA for the spring and summer, which is allowing me to go to Annapolis and instruct the Mids from the academy for IFS. In my opinion while its a good program, the realistics behind it are lacking. While it is done under a 141 program, people learn at different speeds, and for some the 25 hours is not really enough even if the person has the potential to become a good pilot. Going in with the PPL ensures that you have a very firm grasp,(SEE check ride with FAA examiner) on navigation, weather, ect. ect. where as IFS students might miss a few things because of the program structure. Not that I am a huge advocate for the Air Force, but making their pilots get the PPL is probably one of the better things I have seen in my professional (as much as that can be) opinion. As far as planes go, I would recommend at least a 172, its very stable and easy to handle, a 152 would be cheaper, but if you are new to this carry a sic sac on windy days. Plan on about $4-5k when all is said an done, and as far as GPS goes if you want a good GPS that is somewhat user friendly in the plane go for another $2-3k. But seriously have you ever seen the cockpit of a T-34, or most navy aircraft, you better know how to navigate and not depend on the moving map. Besides its all VFR flying, so its beautiful outside right, haha, best of luck and contact me with any questions of if you are going to be in annapolis and are looking for a flight. tonykochanski@hotmail.com
