NASSP MCC data and RTCCMFD providing blank GET data

[mnurick]

I'm on the latest Orbiter Beta and NASSP 8.0 release. Regardless of save file including stock Apollo 11 scenarios, when on the moon preparing for liftoff, MCC pad data is coming with blank liftoff times. I then turned to the RTCCMFD to calculate the burn data manually, and liftoff time also comes out blank (all other data successfully calculates).

Any thought on what might be causing this? I have no problems on my 2011 macbook pro, but on my recently upgraded desktop hardware, I'm running into this issue. Any possibility D3D9 w/ a modern graphics card is interfering with mission timers?

Can you tell me which inputs you did in the RTCC MFD for this? And I guess by blank you mean the liftoff time doesn't calculate and just stays zero?

Hello again Indy!

For the RTCC MFD, I navigated to the PAD menu, selected Lunar Ascent PAD, selected Columbia as the target, and hit calculate.

Also, here is the MCC snippet of the save file, where you can see the zero'd out GET and dV data

Ok, what you have to do in the MFD is to first calculate a liftoff time. You do that under Maneuver Targeting, Lunar Liftoff. There you enter a threshold time for the liftoff, e.g. 124:00:00 GET. Then you click TGT on that page to select Columbia as the target. You hit calculate and that should get you liftoff time and horizontal and vertical velocity. Only now can you go to the page with the Lunar Ascent PAD and let it calculate the missing few parameters for it.

And I found the issue with the MCC, it's a bug in selecting the rendezvous profile for the lunar liftoff time calculation. I'll fix that when I merge my larger RTCC update into the main NASSP release, should be within the next few days. Until then you need to wait or use the RTCC MFD I guess.

Thanks Indy! Noob mistake on the RTCC. Thanks for the fix and glad you found the bug.
