    Apollo 10 P22 Landmark Tracking: REFSMMAT/Alignment Question

    After going back through all my saves, ALL my RTCC_TLANDs were zero. I started this simulation using the Apollo - Mission Scenarios - 10 - 01 - Before Launch T-20min scenario. In that scenario the RTCC_TLAND is already zero. In fact TLAND is zero through the first five canned scenarios. It's...

    Apollo 10 P22 Landmark Tracking: REFSMMAT/Alignment Question

    I don't think I played with the RTCC, at least I don't remember. But I'll dig around and see what happened to the TLAND value.

    Apollo 10 P22 Landmark Tracking: REFSMMAT/Alignment Question

    I was about four minutes+ behind the flight plan time on LOI (mine was at 75:49:46, flight plan showed 75:45). About two minutes behind on LOI2 (mine 80:12:35 flight plan 80:10). FWIW, when I did the P52 opt 1 LLS2 REFSMMAT at 94:50 I saw a big change in the FDAI pitch. So maybe I'm back on...

    Apollo 10 P22 Landmark Tracking: REFSMMAT/Alignment Question

    Hi, I'm trying to do the P22s at approx. 82+00 on the flight plan. For some reason my alignment doesn't seem correct. (See attached images) The last time I uplinked a REFSMMAT was back around 69+30, when we did a re-alignment to LLS-2. The checklist has us maneuver to 000/326/000. There's a...

    Apollo 10: Waste Water Slow to Dump?

    Thanks, working much better. (I was going to make a comment about how at my age reduced waste water flow can be a real pain but decided not to.)

    Apollo 10: Waste Water Slow to Dump?

    I'm not clear on where in my save I would edit this, I've looked around and nothing as glaringly obvious as "WASTEH2ODUMPVALVE" jumps out at me. Could you tell me what line in the saved .scn I would change? Thank you.

    Apollo 10: Waste Water Slow to Dump?

    Hello, at about 6+30 in the scenario we start the first waste water dump. My tank at the start of the dump was only at 0.50, but I went ahead and started dumping. After 40 minutes the tank is at 0.40. I read Miriam's Apollo 12- Experiences, Odds & Ends thread where a similar issue was...

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    Slowly working my way through the rendezvous. On both the CSI P32 and CDH P33 checklists there's a line that reads "If Ydot > 2fps, insert negative Ydot in R2". My Ydot worked out as 0000.6. What would I enter here? The first time I'm asked to enter my CDH time was before I received the PAD...

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    Beginning P32, entering the TPI TIG. The checklist says "Load TIG of TPI (With +3 Min Time Bias)". My PAD TPI TIG is 97 47 28.72. Does that already include the bias? Or do I add 3 minutes to the PAD value and enter 97 50 28.72? The LGC is going to calculate its own TPI TIG later anyway, isn't...

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    OK, things proceeding much better, I'm now at a point about 10 minutes before insertion. The P20/P34 all went well this time, no errors. A couple of questions. What exactly was the whole TPI0 about? Just an exercise to test P20 and P34? During the whole process, I kept manually pitching the...

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    My first attempt this may have come into play, I know I had some drift going on between the CSM and LM. This time through the scenario after the undocking I worked hard to get the CSM and LM station keeping as close to stable as I could. As you said, without V47 I don't know which vehicle was...

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    I think all the problems related to P20. After starting P34 I kept getting 525 alarms (SV/RR LOS > 3 deg). F 06 49 would also pop up, and I don't know what "delta SV" is (or should be), as well as what delta R or delta V should be. Should I accept? Reject? Recycle? An occasional F 06 05...

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    Thank you for the offer. I want to get into the CSM side of this exercise, but for now I'm still trying to figure out where I'm going wrong with the LM procedures. You were correct with your V84 call, when I input a V84 before starting the LM P20 I don't get the OPR ERR light. But I'm getting a...

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    I'd like to get this correct. I think my problems start right after the SEP burn. When I start the CSM P20 and run through the steps, I get to the point where the checklist says, "When attitude OK". What is "OK"? Should the LM be centered in the optics at this point?

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    Tried V79 before V95, didn't seem to improve the situation. Not sure what I've done wrong here. Here's a save at the PAMFD checklist "Phasing +4m" point (I'm about 9 minutes after phasing, I'm running a bit behind but I don't think that should matter here?). Also, thanks for the tip, but I...

    Apollo 9: LM P20 After Phase Burn V80E OprErr?

    Hi, Just completed the phase burn (thanks to a four-year old thread with input from Indy). Starting the LM P20, checklist has us V95E to inhibit updating the SV. Then we start P20, and manually maneuver to the tracking attitude. After the maneuver (I can see the CSM out the window) we hit PRO...

    Apollo 9 Docked DPS Burn?

    OK! (I think)... Went through the docked DPS burn once more. Left the optics zero switch in zero, mode MAN (I guess that tells the CMC that during P40 "Thou shall not pass" commands to the optics). I believe I found an "ENTER" step in P40 I missed after the burn. As you thought, a procedural...

    Apollo 9 Docked DPS Burn?

    OK, I think I follow this. While trying to track down the problem, I've purposely been leaving the optics in CMC to see what happens. But this is actually causing the optics problem when I run P40. If I leave the optics in ZERO, and the mode in MAN, the optics won't drive. And I may have...

    Apollo 9 Docked DPS Burn?

    I went back to a save point where the optics seemed to be working correctly and worked forward. Here's a save from 49+18. At this point I just completed the CSM P30. I have the optics zeroed, with the mode in CMC, and it's holding at zero. Following the PAMFD checklist, I start P40, I get F 50...

    Apollo 9 Docked DPS Burn?

    I'll go back to a "good" save before the DPS burn. It would not surprise me that I messed up something either going into or coming out of the burn. Thanks.
