FlyBy E6B aviation calculator by SkyWriter Software:

FlyBy E6B is an essential flight computer application for all pilots. Designed by a professional airline pilot it includes many features not found in other E6B programs.

Always improving:
FlyBy E6B was one of the very first applications of its kind published for the Palm OS. Used by thousands of pilots the world over, it has evolved from the suggestions and feedback we have received.
