There are some good Excel based weight and balance applications out there that can be copied and customized for your aircraft.

I can't say for missions, but I use the ASA aviation computer (electronic E6B) which works wonders for me (darn the aluminum E6B in turbulence!).When you said graphic calculator, I was thinking like a TI-83 or TI-89.For those of us in the math sector, TI-89 all the way!!!

I just picked up the TI-89 it can do lat/long computations.

Ti-85? Haven't seen one in years. Check out the Ti-89's!! They integrate and differentiate!! Hooah, now that's cool!!
