HP 15CE Aviation Pac

[Geoff Quickfall]

I now have an HP 15 CE of which lots has been posted at this site.

The HP 15CE has a usb cable which enables one to upload and download calculator states into the 15CE.

This works as a backup of the full expanded memory available on this model or to exchange Pacs, which are in development, ala the 65, 67, 41C et al.

In this case, I was asked to produce an aviation pac, which I did. However, I made it a little more quirky. After 45 years of flying and using various HPs on the flight deck:

25C 19C, 29C, 34C, 65C, 67C, 71B, 41CX / CL, 48GX, 42S, various Swiss Micros and many others,

I developed my own set of programs, mainly used on my 41CX and 41CL.

With that in mind, I have created an Aviation Pac with some of the standard programs and some that applied to my airline, long haul operations which will not be found elsewhere but are extremely applicable, IMHO ?

I include a link to a dropbox folder. In it are two Pacs files. One is the Aviation pac which can be loaded into your 15CE via the cable and comes with a full manual. The manual includes the formulae, explanations and examples plus the full ~500 lines of code.

A second file is unique unto itself. It is a Break Schedule program which can apply to any transportation sector to relieve operational fatigue. A version of this was written by me for the 41CX back in 1988 and I have rewritten it for the 15C.

The Break Schedule is standalone as it uses 10 subroutines. This precludes me from adding it to the Aviation Pac as that would limit the direct access GSB routine selection. The full explanation of this routine is also found in the Aviation Pac manual.

I have included photos of the manual as a teaser. I do hope you find this useful, it did take awhile to write, correct and etc. A caveat, I can program in many languages but I am not proficient in any. Please excuse the inelegance of the programming style, suffice to say, it all works and the answers the routines produce are correct.

The answers produced by these routines were checked on other devices and on the internet when the were comparable site calculators.

José González Divasson at thecalculatorstore.com is in the process of creating a rubber overlay similar to the HP 16C overlay currently available at his site for the HP 15CE. You can also purchase the USB cable there, after all, who want to keep coding in a 500 line code????

Please let me know if you actually have access. I set it up for viewing and downloading but NOT EDITING ?

Here are some teaser photos of the manual and some of the routines. If you are able to attend the HHC2024 it will be included in the thumbdrives.

For those that don’t know:

The HP 15CE is the newest version of the HP 15C. It has the capability to emulate a full 16C or a 15C with increased memory.
