    Question Apollo 7 launch - abort mode 1

    Ok, what do you have in Textures\Earth\Elev_mod?

    Question Apollo 7 launch - abort mode 1

    Ah, I can reproduce it now. The terrain near launch complex 34 is not level in Orbiter. That's why NASSP comes with a modified elevation file to make the launchpads we use in NASSP completely flat. If I delete that file then at launch the orientation of the Saturn IB (using the T-60s scenario)...

    Question Apollo 7 launch - abort mode 1

    That seems to be a dip down to 40 fps, which should be ok I would think. Is your Saturn IB slanted, so not pointing straight up? Also, just to confirm it again, this happens every time in every Apollo 7 scenario with you, is that correct? The T-60s scenario provided with NASSP does also cause...

    Question Apollo 7 launch - abort mode 1

    Hmm, so then it seems like you somehow get a big attitude rate for a short moment at liftoff. Can you confirm that on the FDAI rate needles? Is it only at liftoff and then settles down? Do you get a bad framerate at liftoff? Maybe it's related to that. Does it also auto abort if you look at the...

    Question Apollo 7 launch - abort mode 1

    So you are getting an automatic abort. Does it happen right at liftoff? There is only 3 conditions that can really cause it. A sudden high attitude rate, loosing two or more engines or the connection to the IU breaking up (EDS buses loosing power). High attitude rate or loosing engines right...

    Shuttle FDO MFD

    You need to tell it for which maneuver you are adding the constraint, even if there is only one maneuver being planned. So it's not "APO 1" it should be "1 APO 1". That's what the description on the input box means with "Man". This thread is fine, I don't expect there to be much development...

    Shuttle FDO MFD

    That is the most recent version for Orbiter 2016. I did a build for Orbiter 2010 a few months later, but it is identical other than being build against the Orbiter 2010 API. So no code differences. It can! I just tried it, one problem is that if no target is selected the maneuver calculation...

    Apollo 12 - Experiences, Odds & Ends

    The launch window processor doesn't calculate a TPI time either, it needs to be input there as well. The easy way to do it is under Targeting, Rendezvous, TPI times. Choose your CSM as the vessel, use the orbital midnight option and then input an estimate of the TPI time. The "correct" way of...

    Apollo 12 - Experiences, Odds & Ends

    T1 is the last opportunity to abort with P71. That time could be mission specific I guess. The insertion velocity for P70/P71 insertion is variable and T1 is when the chosen rendezvous profile can't be reached anymore. The minimum (normally) targeted apolune altitude is 30NM and that is what you...

    Apollo 12 - Experiences, Odds & Ends

    I downloaded the Apollo 12 landing site sceneries by ggalfi (http://absimp.org/orbitersim/apollolandingsites.html), that enhances the landing visuals a lot. The "Oceanus Procellarum" base marker is basically in the crater where the Surveyor landed. The landing point with the pre-mission landing...

    Apollo 12 - Experiences, Odds & Ends

    Downlink from CMC to RTCC is somewhat redundant as the REFSMMAT was calculated in the RTCC and then uplinked. So it should already be identical. But it doesn't hurt, if nothing changes when pressing DWN then it was already the same. Nothing to switch around in the config, just remember that the...

    Apollo 12 - Experiences, Odds & Ends

    P40 also has a different downlink list for telemetry, just another check that the LGC is in a good state. They often enter P40 early if a burn happens without comm to the ground. CSM and LM REFSMMATs are being treated separately. This might be a case where the button to move REFSMMAT around...

    Question SPS Evasive Maneuver

    You use V25E to load all three DSKY registers. You do that when you want to change the TIG in P30 (Noun 33) and also with the DV (Noun 81). DET is the digital event timer, so when you get to Noun 45 in P30 it shows you a countdown. You then set up the event timer to count up to TIG. The controls...

    V8 Release Work Thread

    Earth landmark markers are now available again! The new style of labels was a bit of a headache to get working, but the big advantage over the old style markers is elevation data. The old style of markers didn't support elevation of landmarks. A lot of Apollo Earth landmarks were on the coasts...

    Apollo 12 - Experiences, Odds & Ends

    Before you started flying Apollo 12 I had already started my own mission but got distracted for a while. Finally got back to it and just did the landing. What I find odd is that the targeted landing site seems to be quite different from the actual one. I have to do a bunch of very early LPD...

    Apollo 16 LM Aborts

    Hmm I think they should be compatible. Did you enter the values in the Timeline Book for the AGS abort constants (page 2, DEDA 224 etc)? Those look quite the same as in the padload for the LGC for Apollo 16. You will find the second half of the timeline book quite useful, starting on page 19...

    Apollo 16 Lunar Descent: P63 and AGS Preparation Questions

    Yes, that's what P76 does. It "simulates" the burn as an instant maneuver at the TIG with the given DV. The circ burn happens behind the Moon, so no uplinks until AOS. And as happened on the actual Apollo 16 mission, things don't always go as planned and the circ burn didn't happen on schedule...

    Apollo 16 Lunar Descent: P63 and AGS Preparation Questions

    The ALSJ has the Apollo 16 Data Card Book: https://www.hq.nasa.gov/alsj/a16/a16DataCardBookChngE.pdf The RTCC MFD does have a way to calculate the abort constants, but because the rendezvous profile following an abort was changing from mission to mission and because from Apollo 11 to 12 they...

    Apollo 12 - Experiences, Odds & Ends

    When in the CSM, go the configuration page. Is that set to LM or LM+CSM docked? It needs to be CSM or CSM+LM. That's the only explanation I have for that behavior. I just tried it, I don't know how it doesn't end up with a CTD but LGC and AGS state vectors appear, even if they surely will be...
