RE: HP 15CE Aviation Pac
Hello Geoff!

I downloaded everyting and am tempted to flash one of my two HP-15CEs with your software (or buy a third one for that purpose...) so that I can add it to my collection of navigation calculators. I really appreciate the effort you put into the manual. Unfortunately I have no use for it at work because ForeFlight (https://foreflight.com/europe/ - there are similar products from other companies, but my employer chose this one) put an end to every other aviation calculator, chart, spreadsheet, briefing package and whatever else one used in the past to plan, prepare and conduct and record a flight. 2024 is the year we live in :-) In "my" aircraft I still keep a Ti-85 that I bought on eBay for one Euro a long time ago and on which I have only two programs, both of which could be added to your package: The first one is called "Delta ISA" and calculates the difference to the conditions in the standard atmoshere using the limited data that our avionics provide: Fight level, ram air temperature and Mach number. It is useful for explaining why the performance of the aircraft is better or worse than on other days. High temperatures (positive values for delta ISA) result in reduced performance, i.e. higher fuel burn, lower climb rate and less speed. On days like that it might be a good choice to cruise at a lower flight level - if available. The second one is called "Fuel" and does the trivial conversion of fuel units in lb, as indicated on our instruments and in our flight planning to litres as required for refuellers in Europe. I have memorised the conversion factor and can do the calculation without a calculator, but for peace of mind I prefer to use my little program. There is no more stupid mistake in aviation than to under or overfuel... Regards Max |
