Does anybody knows the actual paramaters i have to input in RTCC MFD for the Apollo 11 burns (TLI, TLMCC, LOI, LOC, TEI, TEMCC) and so on?

In the DOCS folder there are ones for Apollo 8 and 7, but i don't see any for Apollo 11.

I was trying inputting some parameters from old flightplans that used IMFD and i ended crashing to the moon after second TLMCC which didn't even gave me a chance for LOI burn (the crash was like 5 minutes before calculated LOI burn).

I used nodal targeting for all burns (so TLI and 2 MCC corrections).

I see that there were some people who have completed those burns using RTCC MFD so i hope there gonna be someone who can share the data.

Yeah, those docs are still from the NASSP 7 release. I will add them for Apollo 9-11 at some point before the full NASSP 8.0 release. Some things might still change in the RTCC MFD, so I haven't done that yet.

Ok, for TLI you won't have to do anything. All lunar missions now have presettings for the LVDC++ so that they can perform TLI without any update from RTCC MFD or anything else.

For the midcourse corrections you will want to use the TLMCC option 2 for MCC-1 and MCC-2, and the nodal targeting (TLMCC option 1) for MCC-3 and MCC-4. Most mission specific numbers should already be preloaded in the RTCC MFD, so you basically just have to input the TIG and then calculate the maneuvers.

What dV to expect when performing those manouvers and what are the optimum TIGs?

I got trough TLI without uplinks now and for TIG 4:00:00 GET it shows me somewhere between 100-200 dV which is more than i expected, when i increase TIG this value obviously is getting bigger.

IIRC historic values were much smaller and TIG was somewhere during second day.

Is it normal in NASSP? I was using like 30X time acceleration after post liftoff and then went back to 1X at about 6 minutes prior to timebase 9. I got 10319.7 FPS dV for TLI (measured by EMS).

I also got problems during T&D. In current version stage seems to manouver after separation which makes docking much harder. My procedure described here:
is not working well as stage seems to manouver during T&D.
Shouldn't the stage keep its inertial ATT when separation is commanded?
Or maybe should i just wait for specific time to do T&D when stage stop its manouvers?
