Thanks for the Help - it will help as we develope the SOP's for the aircraft. It is a little older (still nice) in the BB-640's and will be flying about 390 hours in the next 3-4 months (not all me) assuming we can keep it out of MX. I think that It will be tough keeping it in the air that much but we are very cyclical in its use. . . after that it won't see nearly that much flight time until november or so.
