Aviation Pac

Disclaimer:

Please note that this is not a HP product, but rather a custom overlay and program set for checking flight computer results. It is important to remember that this overlay and the aviation pac are meant for supplementary use only, and should never be relied upon as the sole source for flight calculations. We advise consulting your aircraft model manual and following FAA and JAA-approved calculation methods for accurate results.

This Aviation pac has been created by Geoff Quickfall, HP calculator lover and B777 and B787 Captain until retirement.
