Ken Mattingly

Okay. And the first thing you want to do under “EMS initialization,” is circuit breakers EMS, that's two of them, to close.

Jack Swigert (CMP)

Okay. CB EMS, two, to close.

Ken Mattingly

That's correct. All right. Line 4 or step 4, where it shows “CM RCS check.” That occurs at minus 04:30.

Ken Mattingly

All right. Under “CM RCS checks,” the fourth line down says “MANUAL ATTITUDE, three, to MINIMUM IMPULSE.” We'll have to use “ACCEL COMMAND” and the reason for that, Jack, is we don't have the SPS powered up so there's no minimum impulse generator.

Jack Swigert (CMP)

Okay. MANUAL ATTITUDE, three, to ACCEL COMMAND.

Ken Mattingly

That's correct. And on the same page 2-1, strike out the last three lines, starting with “RCS transfer to service module.”

Jack Swigert (CMP)

Right. The last three lines are scratched out. We ain't got one of those things.

Ken Mattingly

That's correct. Okay, let's flip to page 2-2 and strike out the first two lines.

Jack Swigert (CMP)

Okay. Now wait a second. I need to give you volts and amps, Ken.

Ken Mattingly

All right. Go ahead.

Jack Swigert (CMP)

Okay. It's 39.6, 1.12.

Ken Mattingly

Sounds like you're getting there. Okay. I believe we scratched out the first two lines on 2-2. Now, we're—right below that, it says “Separation checklist.” So we're going to just delete that whole thing; it's included in the notes I gave you.

Jack Swigert (CMP)

Okay. It's included in the notations.

Ken Mattingly

All right. Line number 7. It says “Maneuver to horizon check attitude.” We're going to call this the “Moon-check attitude” and this is the one we discussed, Jack. The angle of 265 is not correct. I'll have one of those for you first thing in the morning.

Ken Mattingly

Okay. And at the bottom of the page, step number 1. That will be at EI minus 19 minutes, and we're off and running through a normal sequence of events.

Jack Swigert (CMP)

Okay. That sounds good. Ken, I guess if you've read this thing—Is it a comfortable time line? Any areas where you had problems with?

Ken Mattingly

Jack, it is very comfortable. We've run it several times now and, in fact, it's being run right now, again. And we've run it both here at Houston and at the Cape. The only place where you might find that you need to stay ahead of things is during the platform-alinement period, when you're getting ready to close out the LM and then once you get into the command module and jettison the LM, why you're back on a very comfortable time. And, of course, we'll be watching and anything we can do, like keeping track of time for you, we'll remind you of that as we go along.

Jack Swigert (CMP)

Hey, that would be good—that would be good, Ken.

Ken Mattingly

Okay. Let me emphasize, Jack, that 2-1/2 hours is the earliest time we can start in on that powerup stuff. Everything else you can do the way you normally would, where you get as far ahead of the game as you can. But the 2-1/2-hour time is based on saving command module consumables. And if you do that, why we're fat; we've got plenty of time to give you some fans on the water even. So that's the one point you don't want to start early on. I do have a couple of more lines to run through on the entry checklist and two pages in the G&C. And I think that will clean us up.

Jack Swigert (CMP)

Okay, Ken. And G&C checklist now?

Ken Mattingly

Let me finish a couple more things in the entry book. You still got that?

Ken Mattingly

Okay. On—These are just cleanup items, Jack. On page 2-3, it lists how you separate, from the CM/SM SEP and all that, so, obviously, if we're on step 5 at 43 minutes down—that's all deleted. And that gets deleted all the way over onto page 2-4, up to the line where it says “15 minutes.” And at that point, we pick back up and everything. From 15 minutes down is valid.

Jack Swigert (CMP)

Okay. Delete item 5 down to the point where it says “Minus 15 minutes.”

Ken Mattingly

That's correct, Jack. Okay, on page 2-5. The top line where we had “Horizon check,” that's now the “Moonset check” and the time is approximately 57:37. And that's minus 02:23. And that angle that's listed in the book there—177—that's really a horizon time at 2 minutes; we'll have you—can look that up on the back of your entry cue card, and I'll look that number up again for you tonight.

Ken Mattingly

Okay. Another thing is to remember when we begin blackout, which is around 05g, and you can write this in your checklist wherever it's convenient; once we've lost COMM, we're going to go ahead and power down the SCE POWER OFF and the PMP POWER OFF. And we just want to do that after you lose COMM, which comes up around EI. Any time after that, go ahead and secure the PMP and the SCE power.

Jack Swigert (CMP)

Okay. When COMM is lost, SCE POWER OFF, PMP POWER OFF.

Ken Mattingly

That's correct, Jack, and that completes the entry checklist. Let's look at the G&C book.

Ken Mattingly

Okay. Let's go to page 2-1.

Ken Mattingly

Okay, Jack. The second line under “IMU powerup” says “FDAI POWER to BOTH,” and we're going to make that a “1.” The reason we're doing that is, again, to conserve power. There's no reason to drive the second FDAI before we get that information to put on it.

Jack Swigert (CMP)

Okay. “FDAI POWER to 1.”

Ken Mattingly

All right. That's correct. On page 2-2.

Ken Mattingly

Okay. Under CMC powerup, line—or step 2 says “Flashing 3700, ENTER.” The time we're going to use this, Jack, is going to be when you've just brought the computer up and it has a state vector in it that's way back many, many hours ago. So we want to do a VERB 96, ENTER to stop the integration to keep it from just sitting there ambling along. And when the ground gives you a new state vector, why then we can go through P00 and we'll be back in business.

Jack Swigert (CMP)

Okay. You want me to go to VERB 37, ENTER; 00, ENTER; and then do a VERB 96?

Ken Mattingly

When you come up, I guess you're going to—once you get the CMC powered up, you're probably going to be going—you're going to come up in a flashing 37, and if you'll just do a VERB 96, ENTER right there, that will take care of it.

Ken Mattingly

All right. And the last one I have for you is on page 2-4.

Ken Mattingly

Okay. Under the SCS powerup, the first line says “AUTO RCS SELECT, 16, to OFF.” Okay. You can just delete that part. On the fifth line, it says “Circuit breaker SCS LOGIC POWER,” that's really “LOGIC BUS, four of them, to closed.” The DELTA-V CG is not important since we are not burning the engine. The “SIGNAL CONDITIONER/DRIVER BIAS POWER” lists “Two to AC 1.” We are going to make that just one of them; make it “SIGNAL CONDITION/DRIVER BIAS POWER, one, to AC 1.” The “BMAG POWER,” which is the third line from the bottom, says “BMAG POWER, two, ON;” we are going to make that just one. We'll bring up number 1, and we'll make “FDAI POWER, number 1” and the last line “AUTO RCS SELECT, 16, enable,” you can strike that off and replace it with “BMAG MODE, three of them, to RATE 1.” You want to try reading that back?

Jack Swigert (CMP)

Okay. Delete “AUTO RCS SELECT, 16, OFF.” Change “CB LOGIC POWER” to “LOGIC THRUST POWER—CBS CS LOGIC THRUST, four, to closed.” Delete “DELTA-V CG,” coming down here “SIGNAL CONDITIONER/DRIVER BIAS POWER, one, AC 1; BMAG POWER, 1, to ON,” and it's the number 1 BMAG. “FDAI POWER to 1; BMAG MODE, three, to RATE 1,” deleting the “AUTO RCS SELECT, 16, to enable.”

Ken Mattingly

That's correct. You've got them all, Jack. Very good. Thank you.

Jack Swigert (CMP)

Thank you. This does it, huh?

Ken Mattingly

Yes, sir. Let's see—just a second—let me check on this hatch and integrity check maybe I can tell you something about that. And I do have an answer to your LM power question about the umbilicals. The umbilicals will be unpowered according to the LM procedures, so if you'd like to disconnect them, you can.

Jack Swigert (CMP)

Okay. I think we will.

Ken Mattingly

All right, sir. Okay, Jack, and they'd like us to stand by just a second.

Vance Brand (CAPCOM)

Jack, would you get the BATTERY CHARGER, OFF, please. And we'll send you —

Vance Brand (CAPCOM)

— the rest of that procedure later.

Jack Swigert (CMP)

You mean there's more? Okay, in work. BATTERY CHARGER is going OFF.

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.

Jack Swigert (CMP)

Okay, Vance. The BATTERY CHARGER's OFF, and I'm ready to continue with Ken.

Vance Brand (CAPCOM)

Okay, Jack. And we'll get the backout to you after that.

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.

Jack Swigert (CMP)

I hope so because tomorrow is examination time.

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.

Ken Mattingly

I can't do much about that.

Ken Mattingly

Some people will do anything to set a record.

Ken Mattingly

Hey, Jim, you even did good on service module fuel this time.

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. Don't wake him up yet. Stand by 1.

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.

Jack Swigert (CMP)

Okay. I'm ready to copy the backout procedure.

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, Jack. Do you have that backout procedure in your hand there?

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.

Jack Swigert (CMP)

Okay. Jim will copy that.

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?

Vance Brand (CAPCOM)

WATER TANK SELECT valve, ASCENT. That's correct, Jim.

Jim Lovell (CDR)

And we'll proceed with that right now, and how about still drinking descent water?

Vance Brand (CAPCOM)

Jim, we understand that you should be able to continue drinking, it.

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.

Jim Lovell (CDR)

Okay. And we are now on ascent water.

Vance Brand (CAPCOM)

Okay; okay. And I need Jack back again, please.

Jack Swigert (CMP)

Okay, Vance. I'm here, and you have something in the systems checklist.

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.

Jack Swigert (CMP)

Okay, Vance. I'm ready to copy.

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.”

Jack Swigert (CMP)

Okay. You want me to delete “For 30 seconds.”

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.”

Jack Swigert (CMP)

Stand by. Can you read okay?

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?

Jack Swigert (CMP)

Roger. Loud and clear.

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.”

Jack Swigert (CMP)

Okay. “Until LM/CM DELTA-P equals 3.0.”

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.”

Jack Swigert (CMP)

Well, through that. Leave “TUNNEL LIGHTS OFF” is the only step remaining.

Vance Brand (CAPCOM)

Roger. And just—That's a verify.

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.

Jim Lovell (CDR)

Do you have any more updates for us?

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)

Aquarius, Houston. Over.

Fred Haise (LMP)

All right, go ahead, Vance.

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. You want the—again a look at the docking tunnel index?

Vance Brand (CAPCOM)

Why don't you go ahead and look at that —

Vance Brand (CAPCOM)

Look at that first, yes.

Fred Haise (LMP)

Okay. Jim says the docking tunnel index is a plus 2.1 degrees.

Vance Brand (CAPCOM)

Okay. Plus 2.1 degrees, docking tunnel index.

Fred Haise (LMP)

Okay. He corrects himself. He says make that sign a minus. Minus 2.1 degrees.

Vance Brand (CAPCOM)

Okay. We just changed, plus to minus.

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.

Fred Haise (LMP)

Okay. I've got lots of pages here of Ken's photo log set to go.

Vance Brand (CAPCOM)

Okay, Fred-o. Okay. This is “Entry, LM PREP.” Starts EI minus 6 hours. At that time, you power up the ACS. I think I'll give you a line at a time and, when I hear you say okay on that, I'll go to the next. That sound reasonable?

Fred Haise (LMP)

Okay. I'll go hot mike briefly.

Fred Haise (LMP)

Hey, how do you read now?

Vance Brand (CAPCOM)

Okay. I read you okay, Fred. Okay. Battery 5 —

Vance Brand (CAPCOM)

Battery 5 NORMAL FEED ON is the first step.

Fred Haise (LMP)

Okay, Vance. That—Go ahead.

Vance Brand (CAPCOM)

Okay. Use modified LM DPS/RCS 30-minute activation checklist.

Vance Brand (CAPCOM)

EI minus 5 hours. Midcourse-7, if required. Next: LM preentry procedure. And, Fred, the time on LM preentry procedure is just —

Vance Brand (CAPCOM)

Okay. The time on the LM preentry procedure is just as soon as you finish midcourse-7, or 5 hours -

Fred Haise (LMP)

All right, go ahead, Vance.

Fred Haise (LMP)

Okay. I've got this TEI minus 5 hours, MCC-7 if required, and now you're going to start me a new procedure called LM preentry procedure. Go ahead.

Vance Brand (CAPCOM)

Roger. Maneuver to SM SEP attitude. Configure for CSM hotfire.

Vance Brand (CAPCOM)

Under that, DEADBAND, MAX; and ATTITUDE CONTROL, three, to PULSE.

Vance Brand (CAPCOM)

Perform CSM hotfire. Maneuver back to SM SEP attitude.

Vance Brand (CAPCOM)

And under that, ATTITUDE CONTROL, PITCH and ROLL, PULSE; YAW, MODE CONTROL.

Vance Brand (CAPCOM)

Okay. Next, EI minus 4 hours, 30 minutes. Configure for CM/SM SEP.

Fred Haise (LMP)

Okay. Hold on a minute.

Fred Haise (LMP)

That was EIEI minus 4-1/2?

Fred Haise (LMP)

Okay. That's EI minus 4-1/2 hours, configure for SM SEP.

Vance Brand (CAPCOM)

That's affirm, and under that, BALANCE COUPLE, ON.

Vance Brand (CAPCOM)

AGS 404, plus 0; 405, plus 0; 406, plus 0; and 470, read out.

Vance Brand (CAPCOM)

Translate plus-X at 0.5 feet per second.

Vance Brand (CAPCOM)

Then CM/SM SEP. After SEP, null 470 —

Vance Brand (CAPCOM)

Okay.

Vance Brand (CAPCOM)

After SEP, null 470 to 0.

Vance Brand (CAPCOM)

ATTITUDE CONTROL, three of them, to PULSE.

Vance Brand (CAPCOM)

Pitch to acquire service module for photos.

Vance Brand (CAPCOM)

Okay. Note: use ACA for control.

Fred Haise (LMP)

Okay. We can use the ACA now for control.

Vance Brand (CAPCOM)

Roger. EI minus 3 hours, maneuver and ATT HOLD for Moon view, attitude —

Fred Haise (LMP)

Wait a minute. Was that maneuver in ATT HOLD for Moon view. Is that right?

Vance Brand (CAPCOM)

For—That's affirm.—For Moon view attitude until CM platform release.
