Aha! I thought it would do that by itself. No, I don't. ? Or does it use the times from the launch window processor?Do you know how to calculate an updated time there?

Correct, T-Align is the same as the LS REFSMMAT alignment time for lunar liftoff, which would be LM liftoff time in this case.CSM plane change burn coming up now. I figure that TH1 is the usual 'next hour to TIG' thing. But TH2...input guide says 'align time'. I guess that has to be the LM lift-off time, right?
I haven't seen the light vanish before, only the yellow box for vessel marking. The light should be visible as long as that tracking light is facing the CSM. Do you have a scn I can try to reproduce with?Right, I forgot that TPI time is indeed an input in P32. D'oh!?
Another thing: the LM tracking light seems to 'vanish' when I switch from the SXT view and back. When I switch to the CSM and go to the SXT it's there at the first time. But when I leave the SXT view and come back later, it's not there. I have to switch to the LM and back to the CSM to bring it back. No problem, I just activate the docking HUD and put the crosshairs in the middle of the box, but strange...
FWIW I’ve noticed the visibility range of the LM through the CSM sextant during RV is not quite as high as it used to be in previous builds. I used to be able to spot both the yellow box and tracking light at about 110NM in range, but now they appear at about 80-ish. Not a huge drama, as you’ve pointed out the HUD docking is a sufficient workaround.Another thing: the LM tracking light seems to 'vanish' when I switch from the SXT view and back.

Might just be a perception thing as those distances haven't been changed at all, and the vessel box draw distance is an orbiter thing I believe. I will say the LM tracking light visibility through the sextant isn't is far as it was IRL though, it had the potential to be seen 400nmi away (according to the AOH) but I believe it shows up around 100 in orbiter.FWIW I’ve noticed the visibility range of the LM through the CSM sextant during RV is not quite as high as it used to be in previous builds.

Coming up on LM deorbit burn. Big question: how did they do it? Just bring up P42 and don't PRO on the V99?
This might shed some light on what they did and how they moved forward and whyComing up on LM deorbit burn. Big question: how did they do it? Just bring up P42 and don't PRO on the V99?
Not directly, I believe the best option is to use the space digitals display and check for an impact point based on a burn and iterate from there.Good to know that they did it exactly like I did. Well, without the signal delay, that is.
And I knew it: they did indeed target for some specific impact point. RTCC MFD can't calculate that yet, right?
Ahh those have always been interesting since I do not believe we have the actual data used. I believe what I did is use Google Moon to find an approach path that crosses the photo sites and used the GPM to generate a PC that crosses it. I then picked one of those spots as a landing site REFSMMAT.PC-2 coming up. Two questions: first, what is the target and align time? Lalande? Descartes? Second: how do I obtain the 'photo REFSMMAT'? It has to be some nominal thing, as yaw for tracking the various landmarks is 0°, but the rest -no idea.
It looks like they had an EMP they used to monitor time until TB6.Hi All.
A random Apollo 12 query, regarding TLI monitoring. Seemed like an Odds and Ends type question.
From the Tech Crew Debrief, 5.1:
“The TLI burn was normal in all respects. My one comment is that we had the little additional program in the CMC to count down to timebase 6 which I thought was extremely good. Dick set it up and had it running.“
Any idea what they are referring to?
