Hi,

I am developing this type of software. What I have written at the moment
is a traditional style flight planner with fuel & w+b calculations and a
moving map navigation system for use with digitized maps.

I have tried all the moving map programs on my PDA. No contest, NavGPS
Pro is the best. As for W+B programs Wing X is the best. If I have to
enter any more than my empty weight and empty weight CG then you are not
doing your job. With Wing X I simply pick my particular model of plane
off a list, enter two numbers and I'm done. It shows me a picture of my
W+B envelope as well as a list. It tells me my weight at any time. It
has a complete nav database as well, so I simply tell it where I am and
where I'm going.
