    Apollo 13 Launch Scenario: What should I expect?

    Hey, I'm in the water! Splashdown Update worked like a charm, I was able to get the entry PAD and the REFSMMAT, the P52 opt 1 alignment went well, and the rest of the re-entry went ok, no major issues. I'll probably take it back to just prior to SM SEP, and try to run through it all without...

    Apollo 13 Launch Scenario: What should I expect?

    Before the SM SEP I was able to go through the MCC-7 calculation and then generate an Entry PAD. After the separation, I'm unable to. I've spent three mornings playing with this and can't figure out what I'm doing wrong. I've tried doing it in both the CM and LM. In both cases the simulation...

    Apollo 13 Launch Scenario: What should I expect?

    OK making progress. As discussed I've powered Main B. SM SEP is completed, continuing through the power up. Issues that have cropped up along the way: . As mentioned earlier, during the CM RCS preheat I need the FLT BUS powered to see anything on the P101 test meter. . I needed Direct RCS to...

    Apollo 13 Launch Scenario: What should I expect?

    I'm going to try re-configuring, un-do the LM to CM power transfer, get all the switches and breakers to a baseline config and see what that gives me when I power up. I don't think it really changes my situation though. Since the LM isn't powering Main B anyway, I'll probably have to close the...

    Apollo 13 Launch Scenario: What should I expect?

    I spent a few hours going through the first steps of the entry sequence checklist and tried to follow along looking at a schematic of the DC power system. (Nothing good ever happens when I start looking at electrical diagrams, just ask my Fender Twin Reverb). Anyway, what busses should be...

    Apollo 13 Launch Scenario: What should I expect?

    I edited my scenario with the values you posted: What about the Main Bus A controller values? Should they look like Main B? I ask because I'm still not seeing things work the way I expect (such as: after the initial power up steps I show volts and amps on Main A bus, but nothing on Main B...

    Apollo 13 Launch Scenario: What should I expect?

    To further confuse things... I dug through my saves and tried to figure out what I did. It looks like originally I was OK through a save at 57:48, and then at 58:26 FC2 went NaN (unbeknownst to me). I went as far as 60:17 (with FC2 NaN) with this scenario, then for some reason stopped and went...

    Apollo 13 Launch Scenario: What should I expect?

    I might know what happened. Looking over my notes there was a period from about 58:04 and 58:51 where I was going back and forth to earlier saves and re-doing certain steps (like the LM alignment). I'm guessing at some point I resumed the scenario from a "bad" save that put me out of the proper...

    Apollo 13 Launch Scenario: What should I expect?

    I have a save at 59:10 where FC2 looks OK. Then one at 59:28 where FC2 shows NaN. Reading the transcript it looks like I had finished the CM power down by that point, and wasn't doing anything with the switches or c/bs in the CM. I'm guessing I may have mis-configured something during the...

    Apollo 13 Launch Scenario: What should I expect?

    I think something is way off in the CM. I'm at about 138+00, just completed MCC-7 and maneuvered to the SM SEP attitude. I did the PYRO BAT check, and went through the CM RCS Activation. I don't think the electrical system is configured correctly, not sure I'm getting power to anything. Running...

    Apollo 13 Launch Scenario: What should I expect?

    I've been enjoying NASSP for around two years (my first question on this forum was January 2021). Based on historical data, the odds are 99.98 percent the issue is on my end. :)

    Apollo 13 Launch Scenario: What should I expect?

    I'm at about 136+10, about 6+30 before EI, and I went through these steps: You can see where it refers you to the CM RCS Preheat on the entry checklist: Later they had this exchange: 137:06:57 Haise: And, Joe, Jack just handed me some injector temperatures, if you want to read these on...

    Apollo 13 Launch Scenario: What should I expect?

    I still don't understand where I got off the proper configuration. Something that sends the voltages to the meter isn't powered. The FLT BUS breakers should be out at this point, and I should be able to see readings on the meter without them. I missed something somewhere, there were so many...

    Apollo 13 Launch Scenario: What should I expect?

    :oops: Yes that's the one, when I got to the Flt Bus MN B closed the meter sprang to life.

    Apollo 13 Launch Scenario: What should I expect?

    This was the procedure they read up at about 101:08? I walked through that, trying each step to see if I'd get any indications, and closing the Flt Bus Main B c/b on panel 225 gives me indications on the panel 101 system test meter. With my limited understanding of the system, the heaters...

    Apollo 13 Launch Scenario: What should I expect?

    No, no indications at all. I'll review my baseline configuration again. If that doesn't fix it I'll read through the power up procedures again. Probably one switch or c/b (or more) I missed. :(

    Apollo 13 Launch Scenario: What should I expect?

    At EI -6+30, starting the CM power up. On the RCS pre-heat I don't get any voltage indications on panel 101. Before I run through checking my baseline configuration and re-doing the power up procedure a third time, I wanted to check if this is just a quirk with the simulated panel 101 display...

    Apollo 13 Launch Scenario: What should I expect?

    OK I think I follow you....there was some (incorrect) time already stuck in the LGC that they could see, and they just had the crew input the delta so the time was correct (it was 88 hours, 59 minutes, and 32.74 seconds off)? I learn so much on this forum :)

    Apollo 13 Launch Scenario: What should I expect?

    Found where they (we) uplinked the LGC time... 059:11:47 Lousma: Aquarius, Houston. I think we've got a better way of getting your mission time up. 059:11:56 Lovell: Go ahead with it. 059:11:59 Lousma: Okay. We can do a Verb 55, Enter, and then put an R1, minus 00088. In R2, minus 00059; R3...

    Apollo 13 Launch Scenario: What should I expect?

    The Flight Director Log at 134:31 says "Good clock update" so maybe that's the case. I remember at some point earlier using the RTCC to uplink the LGC clock time. It might have been in all the stuff they uplinked and I missed it.
