We are now reviewing the first software pac for the HP15c: the aviation pac, by none other than Geoff Quickfall, B777 and B787 Captain. While these calculations are all done by the flight computer, Geoff believes that you always need "a second opinion" confirming the results.
He has prepared a fully detailed manual, a set of programs with 469 steps (that can be uploaded onto your HP15c with the VoyagerSave program) and even two overlay proposals
Here below are the contents of the pac. We will work on distributing the actual programs and documentation in the following days. Also let's discuss on feasibility and costs for the overlays made with the same tech as our HP16c overlay.
