If you have a Palm OS PDA, the easiest and simplest flight planning
software available anywhere (and free) is CoPilot. You do all of your
planning on your Palm and then you can carry it with you on the
airplane. If you input your winds aloft, it will lay out your entire
flight plan for you. It''s an amazing piece of software that can also
be used in conjunction with moving map software if you so desire. Check
