    Apollo 10 P22 Landmark Tracking: REFSMMAT/Alignment Question

    When was your LOI and LOI2 compared to the flight plan? I bet this has to do with you getting to the moon later than the flight plan called for which actually happened.

    Apollo 10: Waste Water Slow to Dump?

    This is a known issue and needs to be tweaked in many places other than just the valve outlet. However if you are using a pre save, it likely doesnt have the outlet valve set to 0.050 because those sizes get saved to the scn file at launch. You can create a save from that scn and edit the side...

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    This is the out of plane correction. If you are computing Ydot in PGNS, you have .6 fps, so you can omit entering the negative Ydot into your computation. For CDH you want to use what the LGC provides, the pad is just a ground solution but you want to use the LGC solution. Same as CSI and TPI...

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    Correct you are adding 3 minutes to that initial time to correct for the conic calculations used by the LGC here. This time is used to compute CSI. The LGC will compute a new TPI time of course later based on CSI/CDH but this is to give the initial starting point. So LM-3 was equipped with an...

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    That was part of it, this was called the "mini football" maneuver. This orbit placed the LM in a position to return to the CSM easily and in one orbit should something go wrong in the LM. It also, as you mentioned, allowed the crew to test P20 and P34 before committing to a full rendezvous...

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    What kind of errors are you getting in P34? N49s? 525s? If so you are likely correct on a V84 issue or you have a side lobe lock on. You have the Apollo 9 G&N dictionary that is pretty much the software procedures. What procedures were you looking for?

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    Basically that just means when your auto maneuver is complete. It says "attitude OK" because since the vehicles are moving, the attitude can actually change from the time you begin maneuvering to the first completion. The LM will likely not be centered in the optics because the optics need to...

    Project Seeking Doc: Manually-Aided Onboard Apollo Cislunar Navigation

    Which checklists do you have that aren't already hosted on VAGC and AFJ? We really don't need to duplicate a repository here.

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    Looks like you did something screwy when you did a V84 previously to update the SEP burn, or something with the RR checkout (extra PRO by accident maybe) causing R32 bit to be no longer set. Maybe entered it wrong, omitted it, or forgot a V80. In any case you can re enable this by making sure...

    Project Seeking Doc: Manually-Aided Onboard Apollo Cislunar Navigation

    Hmm I cant seem to find a copy, @indy91 or @thewonderidiot do either of you have a link for the above doc? I found it's citation on NTRS but no link. What kind of checklists? Most of the ones we have are available on the VAGC document library or the AFJ. Were you looking for specifics?

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    Hmmm that sounds correct on first read. You ENTER on the N18, manually maneuver, then PRO to exit the N19 then V80. You don't still have the LR spurious test running by accident do you? Try keying a V79 before your V95 and see if that works. If not, would you mind posting a save? EDIT: One...

    LM Documenttion

    Exactly, even the procedures for the LM charging the CM batteries was actually conceived before 13, and just collecting dust on a shelf for instance.

    LM Documenttion

    Pretty much, gravity would keep the ascent stage on the descent stage. There were I am sure contingencies that necessitated the cable being attached for a launch in the event you had multiple failures that would require the ED system to blow the valves and separate at the same time, but if you...
