In response to several requests, I am making my GNS 430 "cheat sheet" available. This gives explicit directions (e.g., push button A, turn knob B, etc.) for using some of what I consider to be the most important functions of the GNS 430, including the flight plan functions. I made this sheet for my own use, and it employs some personal shorthand. Use at your own risk.
