Final Thoughts

• This MAY all seems like a lot of Work, but the Equipment Learned from N97779 will greatly assist with Conversion to the G-1000 Nav III Aircraft

• A complete understanding of Operations and shortcuts reduces Aircrew Heads Down time!

• Someone is always Flying the Aircraft and Someone is always looking out to “See and Avoid”!

• Do not Punch a Button or turn a Knob without having a pretty good idea of what should happen!

• If you can’t easily find the process/info in the Air –STOP and come back and put time on the Simulator, or in the aircraft on the Ground or in the Hanger!
