Good Morning. I'm slogging my way through the Apollo 7 flight, I'm 122 hours into it and (following the PAMFD checklist) getting ready to do some P22s. But I haven't seen any uplinks (LAT/LONG) on which landmarks I'm going to want to mark. What have I missed here?
Also not sure if I have the correct flight plan for the flight. I've been working off a May 1, 1968 prelim copy, but the flight plan and the PAMFD don't seem to be in sync. I decided to press on using the PAMFD checklist. I think for this particular mission it gives me the basic essence of what they were doing?
And going back to the SPS-3 burn at around 75+48, the first time through I didn't get ignition. I realized my SPS fuel temps were zero, went back and re-did it after turning the SPS line heaters on for a while, and got auto ignition. I didn't see any other issue except for the SPS fuel temp, and didn't see any mention of it on the PAMFD checklist before the burn. I guess they figure that this is just basic systems knowledge and I should know this (which is true). The other question was why hit the Thrust On button? I got auto ignition, so I'm not clear on what they were testing here.
One small PAMFD checklist question: when going through the P40 checklist with the THC clockwise it asks us to verify no MTVC, then put the THC to neutral. Souldn't those steps be switched, THC to neutral then verify no MTVC?
Anyway, any help I can get on the upcoming P22 landmarks would be appreciated. Thanks for the help.
