Symbolic Flight lets you Flight Plan and Pre-Fly your route with Google Earth on your PC before you burn a gallon of gas. Then Go Fly with your laptop or UMPC, a GPS and Google Earth.

"Another picture-perfect flight - IMC outside - VFR inside :) Symbolic Flight is just like VFR - on approach the runway you are going to land on stays in the middle of the screen (and gets bigger) as you approach it!!" -Nat S.
