Seattle Avionics FlightCalc
 

For those of you with Pocket PCs. This is a little freeware gem, built with cockpit use (ie finger not stylus) in mind.

* Does everything a whiz wheel can do.
* Great User Interface
* Holds the calculated answers for use elsewhere, which is a real timesaver.
* Useful timer feature

Only issue is that it doesn't hold Imperial Gallons as a volume measure.

And very nice it is too.

Thanks KCDW. Very useful. :ok:
