FlyBy E6B is an essential application for all pilots. Designed by a professional airline pilot it includes many features not found in the "other" E6B programs. If you are considering a career in aviation FlyBy E6B has functions that you can use in every aircraft you will fly. FlyBy E6B was one of the very first applications of its kind published for the Palm Pilot. Used by thousands of pilots the world over, it has evolved from the suggestions and feedback we have received. Please visit our web site for more detail and screen shots.
