Hello, After a nice long stay on the lunar surface it's time to head home, and I'm (again) looking for guidance on using the RTCC to generate the necessary uplinks and PADs to get me from A to B. I have looked through the RTCC manual and the RTCC MFD Input Reference Guide and I'm still not sure where to begin.
First, pretty sure I need to have the CSM perform a plane change before the LM lifts off, but not sure how to get that info from the RTCC. Is this a General Purpose Maneuver? Or do I play with the LOI processor somehow? Also, what about the REFSMMAT? Do we use a P30 REFSMMAT here?
Second, looking at the RTCC Input Reference Guide for the ascent, I've gone through this a few times but it seems to me I'm missing the big picture. There's a sequence of events that's unclear to me. For instance, it looks like I need to know my lift off time to begin using the Lunar Ascent Processor. But where do I get that? The CSM's orbit is going to dictate that, so until I complete the plane change will these different processors (LLW, LLT) generate any solutions? And am I looking at the "T3, Ascent (Concentric)" section, the "Direct Ascent & Tweak" section, or both? Lots of questions and I don't know where to begin.
As always any guidance will be greatly appreciated. Thanks.
