I am getting close to reaching the 1,500 hours I need to take my ATP test. I know that flight engineers get some credit for their flight time as a flight engineer toward meeting the flight experience requirement for the ATP written and practical test. Is there any hope that a person who was an enlisted aircrewman would get some credit for their flight time based on their MOS description? I know for a fact that the 2,500 hours I have as a CH-53 Crew Chief has served me well as a pilot. If nothing else I got to spend each flight working as a team with two Naval Aviators. As a 6173/6177 I was an occupational aviator and a required crew member for each flight. I hope that my experience as an Assistant NATOPS Instructor, Weapons and Tactics Instructor, and a Crew Resource Management Facilitator means something to the FAA. Would it even be worth my time to try to use my log books and NATOPS training jacket to try to get some credit for my experience?
