00 07 18 37
Vance Brand (CAPCOM): Okay.
00 07 31 29
Jim Lovell (CDR): Okay, Houston. We're starting PTC. We're disabling quads A and B now.
00 07 31 34
Vance Brand (CAPCOM): Roger, Apollo 13. Houston copies.
00 07 33 08
Vance Brand (CAPCOM): Apollo 13, Houston. Over.
00 07 33 11
Jim Lovell (CDR): Go ahead.
00 07 33 12
Vance Brand (CAPCOM): Jim, we'd like to verify that the high gain is secured, that the S-BAND antenna is on OMNI, and OMNI B should be the right antenna. Over.
00 07 33 27
Jim Lovell (CDR): Okay. You want the high gain secured and you want the OMNI on OMNI Charlie, huh? Or Baker?
00 07 33 35
Vance Brand (CAPCOM): That's affirm. And this'll be maintained in the PTC.
00 07 33 39
Jim Lovell (CDR): Okay.
00 07 33 50
Vance Brand (CAPCOM): And the high gain angles for stowage—or for stowing—are pitch minus 52, yaw 270.
00 07 39 21
Jim Lovell (CDR): Houston, Apollo 13.
00 07 39 24
Vance Brand (CAPCOM): Roger. Go ahead.
00 07 39 26
Jim Lovell (CDR): Stand by for another Earth weather picture. I'll give you a mark.
00 07 39 29
Vance Brand (CAPCOM): Okay. Standing by, Jim.
00 07 39 46
Jim Lovell (CDR): 3, 2, 1 -
00 07 39 49
Jim Lovell (CDR): MARK.
00 07 39 51
Vance Brand (CAPCOM): Houston copies.
00 07 40 22
Vance Brand (CAPCOM): Apollo 13, Houston.
00 07 40 24
Jim Lovell (CDR): Go ahead, Houston.
00 07 40 27
Vance Brand (CAPCOM): Houston here. Your rates look very stable. It looks like your rates are damped out completely here. As far as we can see, it would be alright to start the PTC.
00 07 40 39
Jim Lovell (CDR): Okay. We'll give it a try.
00 07 54 29
Fred Haise (LMP): Hello, Houston. This is 13. How do you read?
00 07 54 34
Vance Brand (CAPCOM): Hello, 13; Houston. Loud and clear. 13, Houston is reading loud and clear. How do you read?
00 07 54 48
Fred Haise (LMP): Okay. And do you have any estimate, Vance, on how long we'll be charging battery B?
00 07 55 01
Vance Brand (CAPCOM): Stand by 1, Fred.
00 07 55 21
Vance Brand (CAPCOM): Apollo 13, Houston.
00 07 55 24
Jim Lovell (CDR): Go ahead.
00 07 55 26
Vance Brand (CAPCOM): We'll be charging for 4-1/2 to 5 hours yet, Jim.
00 07 55 32
Jim Lovell (CDR): Roger.
00 08 02 33
Vance Brand (CAPCOM): Apollo 13, Houston.
00 08 02 36
Fred Haise (LMP): Go ahead.
00 08 02 39
Vance Brand (CAPCOM): Fred, recommend that, when your window comes around facing the Earth again, that you catch another one of those pictures, and at the same time, you should probably start PTC again. We might have sent a confusing bit of info up to you. The “disable two quads” only applies to an early step in the procedure. We didn't mean that for the latter part of the procedure where we have the statement “enable all jets.” Over.
00 08 03 15
Fred Haise (LMP): Okay.
00 08 07 33
Jack Swigert (CMP): Houston, Apollo 13.
00 08 07 43
Vance Brand (CAPCOM): Apollo 13, Houston. Go ahead.
00 08 07 46
Jack Swigert (CMP): Vance, Fred said that you had some more information about PTC and a different way of establishing it or something, huh?
00 08 07 55
Vance Brand (CAPCOM): Roger. Referring to the procedure on G/8-2, if you have that open, I'll tell you what we had to give you.
00 08 08 11
Jack Swigert (CMP): Okay. Stand by and I'll get it out.
00 08 08 13
Vance Brand (CAPCOM): Okay.
00 08 08 35
Jack Swigert (CMP): Okay. Go ahead, Van.
00 08 08 38
Vance Brand (CAPCOM): Okay. On checklist G/8-2 under step 5, there's a statement, “disable all jets on two adjacent quads,” and that's what we were referring to when we called up saying “disable quads A and B.” So that's all fine; however, going down now to step 7 where it says “enable all jets,” we hoped that you didn't think we meant leave A and B disabled there. In that case, it's as written. All jets should be enabled. Over.
00 08 09 20
Jack Swigert (CMP): Okay. Our checklist has “all jets” scratched out, and it says “enable couples on all axes.” So what we'll do is—we'll reestablish this thing and come down to that step 7, and we'll enable all jets. That means enable quads A and B. Is that right?
00 08 09 42
Vance Brand (CAPCOM): That's affirm. You'll have A, B, C, and D enabled for step 7.
00 08 09 47
Jack Swigert (CMP): Okay, real fine. I'll start on it now.
00 08 09 51
Vance Brand (CAPCOM): Okay. Understand you're going to reestablish it.
00 08 10 46
Fred Haise (LMP): And Vance, on that picture, I was all set to shoot it just a little before you called, and the Earth hasn't showed up in the window yet. I don't know if we got too far off the bellyband or what.
00 08 11 02
Vance Brand (CAPCOM): Roger. Copy, Fred.
00 08 11 46
Vance Brand (CAPCOM): Apollo 13, Houston.
00 08 11 50
Fred Haise (LMP): Go ahead, Vance.

Vance Brand (CAPCOM): Roger. On the photo, you'll probably have to reestablish the attitude for PTC and then whenever it comes into the window again, why we'll just be standing by for the photo.
00 08 12 06
Fred Haise (LMP): Okay.
00 08 19 49
Vance Brand (CAPCOM): Apollo 13, Houston.
00 08 19 51
Jack Swigert (CMP): Go ahead, …
00 08 19 57
Vance Brand (CAPCOM): Roger, You're coming in a little weak. Have a recommended roll rate for this PTC, if you could copy.
00 08 20 08
Jack Swigert (CMP): Alright. Go ahead.
00 08 20 10
Vance Brand (CAPCOM): Okay. Recommend that you put in R₁ the following: 03750, and that should give you exactly a rate of 0.3 degrees per second. Over.
00 08 20 27
Jack Swigert (CMP): Okay. Enter 03750. Is plus or minus our choice?
00 08 20 38
Vance Brand (CAPCOM): Roger. The same direction you rolled the last time, which I believe is plus.
00 08 20 47
Jack Swigert (CMP): Okay.
00 08 25 06
Jack Swigert (CMP): Hey, Vance, would you monitor our rates and kind of give an idea of when you think they're stable enough to start PTC.
00 08 25 14
Vance Brand (CAPCOM): Roger, Jack. We'll take a look and let you know as soon as they look stable enough.
00 08 25 19
Jack Swigert (CMP): Okay. I've got quads A and B disabled here.
00 08 25 24
Vance Brand (CAPCOM): Roger.
00 08 25 32
Jack Swigert (CMP): Have they come up with an idea of how much fuel I used on the docking and also the P23 session at 5 hours or 6 hours.
00 08 25 47
Vance Brand (CAPCOM): I think we can give you something. Stand by a minute.
00 08 26 59
Vance Brand (CAPCOM): Apollo 13, Houston.
00 08 27 02
Jack Swigert (CMP): Go ahead.
00 08 27 04
Vance Brand (CAPCOM): Okay. It's looking good so far as RCS consumables are concerned, Jack. You're standing about 20 pounds above the curve right now. Looking at the TD&E, you expended 65 pounds or—Stand by—55 pounds, correction on that.
00 08 27 27
Jack Swigert (CMP): How much?
00 08 27 28
Vance Brand (CAPCOM): And 14 pounds on P23s. You used a little more out of quad A than out of the others.
00 08 27 37
Jack Swigert (CMP): Okay. Thanks, Vance.
00 08 27 38
Vance Brand (CAPCOM): Roger.
00 08 27 42
Jack Swigert (CMP): Hey, could you say again the TD&E fuel? We've got a different—we all heard different things.
00 08 27 49
Vance Brand (CAPCOM): I said 65 and then corrected that to 55 pounds.
00 08 27 55
Jack Swigert (CMP): Okay.
00 08 31 36
Vance Brand (CAPCOM): Apollo 13, Houston.
00 08 31 39
Jim Lovell (CDR): Go ahead, Houston.
00 08 31 41
Vance Brand (CAPCOM): Okay, Jim. Your rates look good. It's okay to start the roll again, if you'd like.
00 08 31 50
Jim Lovell (CDR): …
00 08 41 46
Fred Haise (LMP): Hello, Houston; Apollo 13.
00 08 41 49
Vance Brand (CAPCOM): Apollo 13, go ahead.
00 08 41 53
Fred Haise (LMP): Okay. Ready for a little count here, Vance, and I'll shoot another picture. We found the Earth again.
00 08 41 59
Vance Brand (CAPCOM): Okay. We'll be standing by, Fred.
00 08 42 05
Fred Haise (LMP): A 3, 2, 1 -
00 08 42 09
Fred Haise (LMP): MARK.
00 08 42 11
Vance Brand (CAPCOM): Roger. Copy.
00 09 02 47
Fred Haise (LMP): Hey, Houston, 13.
00 09 02 50
Vance Brand (CAPCOM): Roger. Go ahead.
00 09 02 52
Fred Haise (LMP): Okay. Stand by for a mark on another picture.
00 09 02 55
Vance Brand (CAPCOM): Okay. Standing by, Fred.
00 09 03 09
Fred Haise (LMP): 3, 2, 1 -
00 09 03 12
Fred Haise (LMP): MARK.
00 09 03 17
Vance Brand (CAPCOM): Okay, we got it.
00 09 23 58
Vance Brand (CAPCOM): Apollo 13, Houston.
00 09 24 08
Jim Lovell (CDR): Go ahead, Houston.
00 09 24 11
Vance Brand (CAPCOM): Jim, Houston here. Two items: first of all, your PTC is looking very good and it should carry you through the night; second point, have a procedure to give you, if you're ready to copy. We'd like to set three bits in the computer, and I'll explain why.
00 09 24 43
Fred Haise (LMP): Go ahead, Vance, we're ready to copy.
00 09 24 46
Vance Brand (CAPCOM): Okay. The procedure is as follows: VERB 25, NOUN 07, ENTER; 1331, ENTER; 7, ENTER; and ENTER. Explanation as follows. During the P23s, there was one time when VERB 37 was entered into the computer at about 16 seconds after the OPTICS ZERO switch was flicked to ZERO. This is a very uncommon anomaly in that, if you do this during—0.4-second interval at around 16 seconds after you zero the optics, some OPT-mode bits are reset; and this would mean that, if you had a OCDU fail, it wouldn't be indicated; so all this procedure is doing is setting these three bits back again where they should be.
00 09 26 01
Fred Haise (LMP): Okay, Vance, and I guess I'll try to be slower on that VERB 37.

00 09 26 07
Vance Brand (CAPCOM): Yes. Actually slower or faster, either one, I guess. Well, yes, slower. It's a very unusual thing to have that happen.
