Greetings,

Just was astonished to find out in useful links, Calcs, in sub-calculation named Trig., that cosine 90 deg=6.12... It is not what I was taught in school. ;> I was indoctrinated that cosine  90 deg. = 0.  Live and learn. ;> ;> Definitely, some kind of glitch. I'm checking other sub. calcs. But a warning that all results from those calcs should be kinda checked for "sanity." I hope this was The only glitch.

By the way, I opened those calcs with Google Chrome.

Rumata,

I'm not sure what you're referring to. Do you mean the spreadsheet program Astron? If so, there are two versions of the program;

- Astron.xlsx (for Windows Excel)

- Astron.ods (for LibreOffice Calc)

Please let me know...

CelNAv57,
you were right. It came from Useful Links, Navigational spreadsheets.  When you open it and scroll down you'll see free download Zip file 7 mb which includes 47 spreadsheets for calculations of almost anything. So, I'm still checking some calcs but for NvForum members: please be careful and re-verify your results if you'll use those spreadsheets.
