- Jack Swigert (CMP)
-
Okay, Vance. Okay—I don't think you've given me the backout procedure, have you, for the battery chargers?
- Vance Brand (CAPCOM)
-
That's negative. Wait. All we want to do, Jack, is say BATTERY CHARGE OFF at the moment. We'll complete that procedure as soon as you are through with Ken completely.
- Ken Mattingly
-
Okay, Jack. It looks like we've closed up the loose ends here. Amazingly enough, out of all that stuff, it looks like we only generated one question on the floor, and we'll research that one. We'll even let you guess what it might have been. If you have any questions, after you mull it over, why, we're always available. Just ask us what you're thinking about.
- Jack Swigert (CMP)
-
Okay. That's what we're going to do. We're going to wait until the LM people get theirs, and then we're going to discuss it and coordinate things here, and make sure that—that we don't have any interface problems. And, if we have any more questions, we'll be coming back at you.
- Ken Mattingly
-
Okay. We did run the thing integrated, so we think we've got all the little surprises ironed out for you.
- Jim Lovell (CDR)
-
Appreciate the work you've done, and Jack says that it's going to be hard to beat his record about saving SM RCS fuel all the way there and back.
- Jack Swigert (CMP)
-
Yes. We're coming back with a full load almost of both RCS and SPS, that's—That's pretty much of a record.
- Jack Swigert (CMP)
-
Okay. Did you want to put Fred-o on, or somebody to copy the LM—the LM side of the house.
- Vance Brand (CAPCOM)
-
Hey, Jack. We'll give you this battery charging backout procedure, and then Deke says you ought to get some sleep. You're going to need it tomorrow.
- Vance Brand (CAPCOM)
-
Okay. Panel 3: BATTERY CHARGE, OFF—you've already done that, Jack—next AC INVERTER, INVERTER 2 OFF: Panel 5: MAIN BUS TIE BAT B/C to BAT B/C. Huh? Yes, it's up—the up position. Panel 250: circuit breaker, BAT A POWER ENTRY/ POSTLANDING to open; circuit breaker, BAT B POWER ENTRY/POSTLANDING, open, Panel 5: CB BATTERY CHARGER BAT B CHARGE, open. Okay. I'll let you read that back, Jack.
- Jack Swigert (CMP)
-
Okay. BAT CHARGE, OFF; AC INVERTER 2 to OFF; MAIN BUS TIE, BAT B/C to on, up. Panel 250: BAT A, POWER ENTRY AND POSTLANDING, open; CB, BAT B, POWER ENTRY and POSTLANDING, open. Panel 5: CB BAT CHARGER, BAT B CHARGED, open.
- Vance Brand (CAPCOM)
-
Okay. That's correct. Now, that gets you back to the place where you can back out of the—the big battery charging procedure, which you have. And I—I think you have the backout procedure for that, but I'd like to check with you.
- Vance Brand (CAPCOM)
-
Okay. Just to verify. It starts out panel 3, BATTERY CHARGE switch, OFF; AC INVERTER 2, OFF; panel 5, MAIN BUS TIE, BAT A/C, on, up, et cetera.
- Jack Swigert (CMP)
-
Roger. Continues CB BAT A, POWER ENTRY/ POSTLANDING, open; INVERTER POWER 2, MAIN B, open; and then you reverse the steps that you had for entering the procedure.
- Vance Brand (CAPCOM)
-
Yes, that's fine. Okay. And we have one other comment regarding the systems checklist, and stand by 1, and that'll—that'll wrap it up for us. Oh, a new item came in, Jack. We need to switch to ascent water, and I have a three-step procedure for you, if you're ready to copy.
- Vance Brand (CAPCOM)
-
Okay. DESCENT WATER valve, CLOSE. ASCENT WATER valve to CLOSE, and WATER TANK SELECT valve to ASCENT.
- Jim Lovell (CDR)
-
Okay, Vance. DESCENT WATER valve, closed; ASCENT WATER valve, closed; and WATER SELECT TANK to ASCENT. Is that correct?
- Jim Lovell (CDR)
-
Okay. We switched to ascent water, but we'll probably have to have the descent water valve back open up again to drink water.
- Vance Brand (CAPCOM)
-
That's affirm. That's the one thing you'll have to do is, whenever you want to drink out of the descent tank, is open the descent valve—the DESCENT WATER valve momentarily.
- Vance Brand (CAPCOM)
-
That's right. Refer to S/2-6. This—Really what we're talking about, Jack, is the hatch integrity check decal. And I think it'll be easiest, if you'll open to S/2-6 and I explain it to you.
- Vance Brand (CAPCOM)
-
Okay. This will—This just involves changes. Look down to the third line where it says “TUNNEL VENT valve, TUNNEL VENT for 30 seconds;” cross out “30 seconds” and cross out the two lines below that. In other words, “LM CSM DELTA-P. Check DELTA-P and recycle to TUNNEL VENT.”
Expand selection up Contract selection down Close - Vance Brand (CAPCOM)
-
That's affirm. And the two lines below “30 seconds.” And actually the part of the fourth line there, which is “8-1/2 minutes.”
Expand selection down Contract selection up - Jack Swigert (CMP)
-
Okay. Delete the two lines below that, or the two-and-a-half lines below that, also.
- Vance Brand (CAPCOM)
-
That's affirm. And now, we have an addition to put in place of what we deleted. Stand by 1; the COMM's bad. How do you read?
- Vance Brand (CAPCOM)
-
Okay. We want you to vent—tunnel vent until, and add the following, “Until LM/CM DELTA-P is equal to 3.0 psid.”
- Vance Brand (CAPCOM)
-
Okay. And that means that you'll have a pressure of 1.5 to 2 in the tunnel, absolute. That's —
- Deke Slayton
-
Jack, that's what we want to end up with ultimately is 1-1/2 to 2 there in that tunnel and depending on the gage reading, but that should be about 3.
- Vance Brand (CAPCOM)
-
Okay, then, Jack. Continuing on, everything's okay until you get down to—on the next page, you get through “Verify O2 FLOW INDICATOR no increase.” We would like to delete everything below that, until the last step, which is TUNNEL LIGHTS, OFF. So starting with “Before undocking only,” delete all lines through “TUNNEL VENT VALVE to TUNNEL VENT.”
- Jack Swigert (CMP)
-
Okay. Delete the section that says “Before un-docking only” down to where it says “TUNNEL VENT VALVE to TUNNEL VENT.”
- Vance Brand (CAPCOM)
-
Okay. Really what this does for you, then, is it gives you a pressure—a tunnel pressure integrity—or a hatch pressure integary—integrity check with a DELTA-P of 3 psi between the tunnel and the cabin. And then you never go on to the steps of venting that on out. You just leave it in there for the time that you separate from the LM. And that gives you a shotgun DELTA-V effect.
- Vance Brand (CAPCOM)
-
Okay. I think that's all, but we're polling the house here to see if there's another comment for you. Stand by.
- Vance Brand (CAPCOM)
-
Jack, that's it. Unless you have any more questions, why, everyone is hoping you'll hit the sack and get some rest.
- Jack Swigert (CMP)
-
Okay. You want that battery backout procedure now to take that—to complete the remaining steps?
- Vance Brand (CAPCOM)
-
That's affirm, Jack. We request that you go ahead and finish out the backout completely until you get to square 1. Over.
- Vance Brand (CAPCOM)
-
We've still got a LM update, but we strongly recommend that you and Jack work as hard as you can sleeping for about the next 5 hours. Fred can handle it.
- Jim Lovell (CDR)
-
Okay. That's what we'll do. We'll put Fred on watch here, and Jack and I will take it easy, and if Fred copies the LM update, well, then we'll all start from fresh in the morning.
- Vance Brand (CAPCOM)
-
Okay, Fred. Two—three things. First thing is we need a docking angle check as soon as you can conveniently get it. Second point, you're free to drink all the descent stage water you want, if that wasn't clear before. And the third point, if you have a piece of paper, stand by to get writer's cramps. We have something to give you here.
- Fred Haise (LMP)
-
Okay. And your second item was, we can drink all of that descent waster that's left—looks like about 5 percent, and I'll get a book here and be ready to start writing.
- Vance Brand (CAPCOM)
-
Okay. Get—This won't be as long as—as the one T. K. read up, but you'll need several pages, probably.
