 06-05-2017, 09:23 PM #1 ElonSatoshi Orbinaut How do I calculate my heading with align plane MFD? So I was wondering if there was a way to calculate which heading I should take to rendezvouz with the ISS, using the Align Plane MFD. Or maybe a way to calculate my heading based on my latitude and the ISS's inclination. Short of that, is there a chart showing which headings to take from each base?

After install, doc is "DGIV_Documentation_ en.pdf" in "Orbiter_ROOT\Doc\DeltaGliderIV\res" folder. You can also download this XL file: https://www.orbithangar.com/searchid.php?ID=5222 Sorry, it's in Italian. Maybe I'll translate it, if there's need to.

I am in the mindset that 2010 is what people are still using. Glad it helped tho! It's a nifty equation. Last edited by Samuel Edwards; 06-10-2017 at 06:55 AM.

If UMMU were finally updated and not broken in 2016, there'd be no reason to use 2010. Finally, uneven terrain? I couldn't resist. I just hope 2016 works on Wine. I hear it doesn't. And that's why this new laptop still has Windows and not Gentoo. Last edited by ElonSatoshi; 06-10-2017 at 11:48 PM.

Did he/she see this page? http://www.orbiterwiki.org/wiki/Runn...ter_under_Wine Quote: Originally Posted by Samuel Edwards   Code: `azimuth = arcsin ( cos (inclination) / cos (lattitude) )` Quote: Originally Posted by ElonSatoshi  I'll have to memorize that equation, thanks! This equation is only a rough estimate. Here is a version that's closer to reality. Launch MFD calculates this and other stuff as well. P.S. Let's move the Wine discussion here.

Well...I "created" the need, and now you can download an English version of it. https://www.orbithangar.com/searchid.php?ID=5222 Last edited by Ripley; 06-13-2017 at 03:37 PM.
