CoPilot is a software application program for Palm OS handhelds that performs general aviation flight planning calculations the calculations that you would usually perform with a ruler, a protractor and an E6B calculator. CoPilot stores the data for flights so that you can refer back to previous trips or modify them for new trips. CoPilot is based on the concept of a flight. A flight consists of four components a flight description, a route, a weight and balance calculation, and a flight plan. Each of these components has an associated form. The information that you enter on these forms is automatically stored in the flight database. The number of flights that can be kept is limited only by the total memory on the Palm handheld. CoPilot can be customized Preferences form to use any set of units.
