Using the latest beta build, I practised the LM ejection procedures (using both a quicksave scn from previous builds, as well as the stock A11 mission scn no. 05 “Before S-IVB Separation T+3h+15min”). All went well (T&D, pressurisation) until the actual LM ejection. The separation switch does not do anything (evidenced by lack of separation following from -X thrusting). Double-checked the cb’s and pyro were all properly set IAW the checklist. Can anyone verify if that situation works for them?

Could you post your current state scenario. I'll take a look at it.
Some of the mission scenarios can get a little outdated as we add systems , but I don't think this particular problem would occur.

Thanks N72.75. I've changed the filename from .scn to .txt to make the forum happy.
It's based off the stock A11 scn I mentioned above, and is at about GET 4 hours. I closely followed checklist MFD, and the scn is just at the point prior to starting P47, followed by ejection. I just tried ejection again, and nothing. Curious if it's just me...

I tried your .scn on NASSP build 1537, I had no issues with LM/LV sep.
Unlike CSM/LV sep, LM/LV sep does not have any initial impulse to it, I believe it just unlatches the LM from the LV. The impulse comes from -X RCS thrusting. Perhaps you did not see any relative movement upon throwing the switch and thought the separation had failed?

So all I did was open your scenario, was open it with the most recent version (Build 1537, this is the one that @indy91 just updated with the "Sundance306ish" LM software, Apollo 9 and the S1b LVDC updates).
I ungarded and hit the LM/SIVB switch, and momentarily flipped it up. and than translated -X to extract the LM.
There is no release sound here, and I can't remember if or when there was one, because it's been a while since I did a LM extraction in a mission.
You got all the circuit breakers and switches set right, the ones that are hard to find are the panel 278 ones, but you got them all.
