Jim Lovell (CDR)

Okay. Because I thought he said 2 degrees per second. Like to check on that.

Fred Haise (LMP)

Okay, Houston; Aquarius.

Fred Haise (LMP)

Okay. Jim thinks he heard something different than I copied on the DAP load. Is REGISTER 1 supposed to be 31120?

Vance Brand (CAPCOM)

That's correct, Fred. That was to be 31120.

Jim Lovell (CDR)

And, Houston, how do you want us to …

Jim Lovell (CDR)

… 3, 2, C and D, 2, 2, 0, … Okay. We're at high bit rate.

Fred Haise (LMP)

Okay. … give … a call.

Jim Lovell (CDR)

Well, they probably don't know what to do there.

Jim Lovell (CDR)

Okay. And, Houston; Vance.

Jim Lovell (CDR)

Just want to get a time check with you. When do you want us to start powering up the ball? We just got to our PTC attitude.

Vance Brand (CAPCOM)

Understand you'd like to know when to power up the -

Jim Lovell (CDR)

We think to take about 15 —

Fred Haise (LMP)

Yes. The ball inside the maneuver, we think it will take us about 15 minutes to get there. We'd like you to confirm that.

Jim Lovell (CDR)

What would that take to use … use the command module or what? To load the PLSS

Fred Haise (LMP)

… … Let's see, about 10 or 11 …

Jim Lovell (CDR)

When is that Sun check time supposed to take place?

Fred Haise (LMP)

74 hours 29 minutes …

Jim Lovell (CDR)

Okay, Houston; Aquarius. I'd just like to do the little Sun check. Do you want me to do it now?

Vance Brand (CAPCOM)

Jim, Roger. We just came up with a maneuver time of approximately 15 minutes, so if you start any time between now and about the next 2 minutes it would get you into attitude by 73:15. Over.

Jim Lovell (CDR)

Roger. We'll start the maneuver at this time. Okay. Let's go.

Jim Lovell (CDR)

If we don't keep working, we'll never develop it.

Fred Haise (LMP)

… now, Power up your FDAI.

Fred Haise (LMP)

Okay. Give me 16 … Apparently. … panel 11 …

Fred Haise (LMP)

And on your HA, yaw right side, lift main line … …

Fred Haise (LMP)

Now … 30 second … Okay. Now let's get ready to run this back. …

Jim Lovell (CDR)

Okay. DEADBAND OPTION.

Fred Haise (LMP)

Okay … on this … vector. Okay, R1 plus 45498 … Okay, plus 190 …, plus 08256. Okay, now we show zips … Okay. VERB 62 ENTER. Okay. … and the main … in AUTO … …

Jim Lovell (CDR)

Roll, yaw, roll, pitch, and yaw.

Vance Brand (CAPCOM)

Jim, that's negative. We don't have any data on you. Low bit rate.

Vance Brand (CAPCOM)

We don't have high bit rate.

Fred Haise (LMP)

Houston, do you read Aquarius?

Vance Brand (CAPCOM)

Roger. Reading you, Fred. Go ahead.

Vance Brand (CAPCOM)

Go ahead. Houston is reading you.

Vance Brand (CAPCOM)

Reading you loud and clear. Go ahead.

Jim Lovell (CDR)

Are you monitoring our P52 technique?

Vance Brand (CAPCOM)

That's negative, Jim. We do not have high bit rate data on you now. Over.

Fred Haise (LMP)

And be advised, Vance, that we are getting several echos in our COMM downlink here.

Vance Brand (CAPCOM)

Roger. We'll check into it.

Jim Lovell (CDR)

… … and … alinement.

Vance Brand (CAPCOM)

Jim, request you give us high bit rate now. We might be able to fix you up on the 120 antenna.

Fred Haise (LMP)

And, zero, zero, zero.

Vance Brand (CAPCOM)

Fred, we can't lock up on your high bit rate. Request you go back low bit rate.

Fred Haise (LMP)

Hey, we lost you there, Vance.

Vance Brand (CAPCOM)

Roger. Advise, we are not locking up on your high bit rate, so you can go back low bit rate. Over.

Fred Haise (LMP)

Right here, Jim. There it is. Looks like it …

Jim Lovell (CDR)

I don't have all the confidence in the world in this Earth-Sun P52.

Jim Lovell (CDR)

You know how many times I screwed up on my arithmetic.

Fred Haise (LMP)

Yes. Don't count your chickens before they hatch.

Jim Lovell (CDR)

We're … going to be two diameters out, huh?

Jim Lovell (CDR)

Okay. Tell me what that technique is to get the lamp on, in case I don't see it.

Fred Haise (LMP)

They'll have to give you AC again and you punch in your breaker -Well, let's see—I've still got HP on for the FDAIs, so you're in business now. All you need is the lamp breaker, the AC BUS A AOT lamp breaker, that is.

Jim Lovell (CDR)

Let me know when these start going. There's the Sun. Give me the—Give me the AOT.

Jim Lovell (CDR)

Never mind. I don't need it. Go ahead. I got it. Never mind.

Fred Haise (LMP)

Reticle brightness, want it up? Got the reticle?

Jim Lovell (CDR)

I got the reticle …

Fred Haise (LMP)

… Call it, Jack; you can see it better.

Jim Lovell (CDR)

… we got it a great big one.

Fred Haise (LMP)

Yes. I show it about maybe a third of a diameter to the left.

Fred Haise (LMP)

Check your needles. You're off in roll, Jim.

Fred Haise (LMP)

Pitch and yaw are in, but we're off in your roll needle. Better get that …

Jim Lovell (CDR)

Okay. It brings it in. Say when.

Jim Lovell (CDR)

Okay. We got it. I think we got it. What diameter was it?

Fred Haise (LMP)

Yes. It's coming back in. Just a second.

Jim Lovell (CDR)

Yes, yaw's coming back in.

Fred Haise (LMP)

… upper right corner of the Sun.

Jim Lovell (CDR)

Okay. It looks like the Sun check passes.

Vance Brand (CAPCOM)

We understand it checks out. We're kind of glad to hear that.

Jim Lovell (CDR)

It's not quite centered, but it's about a diameter, a little bit less than a diameter, just to one side.

Jim Lovell (CDR)

Now. Let's get the AOT lamp on.

Jim Lovell (CDR)

Which … to get the AOT lamp on?

Fred Haise (LMP)

Okay. Pull the—your AOT lamp breaker.

Fred Haise (LMP)

Okay. And, Houston, can we proceed with our powerdown now? Getting the ball back off and AOT lamp, et cetera, AC secured.

Vance Brand (CAPCOM)

Stand by on that one for a minute, Fred.

Fred Haise (LMP)

— the ball … get back to—Okay. What we'd like now, I guess, is the next attitude to go to, Vance, and we will work on getting there while we still have the ball.

Jim Lovell (CDR)

Okay. Seventy-four hours.

Fred Haise (LMP)

Yes. We're not there yet, really. I've got 11 minutes to check … out.

Fred Haise (LMP)

Yes. Bring your … down.

Fred Haise (LMP)

Get set. Keep … It's better in here. Slow now …

Vance Brand (CAPCOM)

Jim, in a moment we will have an attitude for you to go to, and recommend that you keep your FDAI up while maneuvering to that attitude. After you get there, then we will have you widen the deadband and eventually go into a PTC about the burn attitude.

Jim Lovell (CDR)

You were cut off slightly, Vance.

Vance Brand (CAPCOM)

Roger. We will have an attitude for you to maneuver to in a moment. And you should leave your FDAI up for that. The attitude is as follows if you are ready to copy. Over.

Vance Brand (CAPCOM)

Okay. This is FDAI attitudes for the maneuver. Yaw 060 degrees, pitch 083 degrees, roll 272 degrees.

Jim Lovell (CDR)

Let's not read that in the R1, R2. I don't want VERB 69 twice. I want VERB 49, 58g's so I can fly the needle.

Vance Brand (CAPCOM)

Jim. Those are not VERB 49 angles. Those are strictly FDAI attitudes. Over.

Jim Lovell (CDR)

Okay. I understand, Vance. It's much easier if the ball is up to fly the needles; that gives me a drift of VERB 49, 58g maneuver. We could fly that manually.

Vance Brand (CAPCOM)

Stand by. We'll try to get you a VERB 49 angle.

Jim Lovell (CDR)

On that last check, what did it look like?

Jim Lovell (CDR)

This is the first three-man LM we've had.

Fred Haise (LMP)

And, Vance, which—What hack you got now on GET?

Vance Brand (CAPCOM)

Okay. Stand by on that, Fred. First, let me read up your VERB 49 attitude, if you are ready to copy.

Vance Brand (CAPCOM)

Okay. Yaw 27100, pitch 35500, roll 33000. Over.

Jim Lovell (CDR)

Ask him if you keep it in AUTO maneuver there.

Fred Haise (LMP)

Okay. VERB 49, yaw plus 27100, pitch plus 35500, roll plus 33000. And do you think it's cheaper to manually make that maneuver or take the 0.2-degree range and go in AUTO maneuver?

Vance Brand (CAPCOM)

Fred, we're recommending AUTO maneuver. Over.

Fred Haise (LMP)

Okay. AUTO maneuver, and could you give me a GET right now.

Vance Brand (CAPCOM)

Okay. I understand you want GET of the burn. Stand by 1.

Fred Haise (LMP)

That's negative, Vance. What is your clock reading right now?

Vance Brand (CAPCOM)

Okay. When I give you a hack, it will be 73:59, and that's about 40 seconds away.

Fred Haise (LMP)

Okay. I think we will make one last check there with the half-unit vectors for 74 hours before we leave this attitude.

Vance Brand (CAPCOM)

Okay. And I'm going to calculate in the 2 seconds in giving you the time hack coming up on 73:59:00 when I give the mark. Okay. Stand by.

Vance Brand (CAPCOM)

Okay. I understand you got it.

Fred Haise (LMP)

You want me to PROCEED one more time on that, Jack?

Jim Lovell (CDR)

Oh, it's on; it's a center.

Jim Lovell (CDR)

That's it, she's right on still. Okay. I have, too. That's better than I expected.

Fred Haise (LMP)

Okay. Let's do a VERB 74 and get out of here.

Jim Lovell (CDR)

If we can. Go to P00? Okay. I'm going to go to -

Fred Haise (LMP)

737100. Roger. 35500, plus 33000. …

Fred Haise (LMP)

Yaw, pitch, and roll.

Jim Lovell (CDR)

Let me see. No, that's yaw, pitch, and—Okay. Everything's … … That's roll, pitch, and yaw.

Fred Haise (LMP)

Roll, pitch, and yaw.

Jim Lovell (CDR)

The roll's going to be down here, but the yaw will be off the bellyband. … procedure, or don't you have a procedure?

Jim Lovell (CDR)

Roll, pitch, and yaw, but drift's the one. That would be gimbal lock if it wasn't for being off …

Jim Lovell (CDR)

And, Houston, I see that this maneuver gives us a roll of 27172, a pitch of 08301. Is that what they gave us?

Vance Brand (CAPCOM)

This is Houston. Please repeat.

Jim Lovell (CDR)

Houston, did you give us VERB 49 in yaw, pitch, and roll, or register 1, 2, and 3?

Vance Brand (CAPCOM)

We gave it as yaw, pitch, and roll.

Jim Lovell (CDR)

Okay. We wrote it as roll, pitch, and yaw.

Vance Brand (CAPCOM)

Okay, Jim. We read it to you as yaw, pitch, and roll, and we should have given it to you registers 1, 2, and 3; but we did not. So register 1 is 33000, register 2 is 35500, and register 3 is 27100.

Fred Haise (LMP)

Okay, Vance. Register 1 will be 33000, register 2 35500, register 3 27100.

Vance Brand (CAPCOM)

Hey, Fred? Stand by on that.

Fred Haise (LMP)

Okay. Plus 27100. Okay. Stand by. Right now you can enter …

Vance Brand (CAPCOM)

Okay. Apollo 13, Houston.

Vance Brand (CAPCOM)

Okay, Jim. We sorted it out, and it is correct the way we gave you the first time. So, R1 27100, and in the LM, that's yaw; R2 35500, and that's pitch; R3 33000, and that's roll in the LM. Over.

Jim Lovell (CDR)

I agree with you. Okay. 5018, it's there, and 5018, and that's what it will be. Okay.

Vance Brand (CAPCOM)

That's right. That's VERB 49.

Jack Swigert (CMP)

There are 25. 25, ENTER.

Jack Swigert (CMP)

Okay. Plus 27100, plus 35500, plus 33000.

Fred Haise (LMP)

So far we're … what can we do about it?

Vance Brand (CAPCOM)

Apollo 13, Houston. You better watch that middle gimbal. Over.

Fred Haise (LMP)

Roger. We're watching that middle gimbal. We have as a roll, 27172. Our yaw is—that's register 3—3300. How did we get this?

Vance Brand (CAPCOM)

And, Apollo 13. We have a procedure for you describing how to widen the deadband to 5 degrees later on. But stand by for that.

Vance Brand (CAPCOM)

Apollo 13, you're heading for gimbal lock. You better stop everything.

Fred Haise (LMP)

Yes, we're back in ATT HOLD now. We're trying to stop it.

Jim Lovell (CDR)

I'm going to roll it.

Fred Haise (LMP)

Can you give it a roll up now, Jim?

Jim Lovell (CDR)

I don't understand why we got that.

Vance Brand (CAPCOM)

Apollo 13, Houston. It looks like VERB 49 maneuver will just take you right through there. You're going to have to go around it. Over.

Jim Lovell (CDR)

Okay. That's what we're in the process of doing.

Fred Haise (LMP)

We're manually working our way around it, Vance.

Jim Lovell (CDR)

How do I work my way around it? I'm 58g's, and I want yaw 231, right? I think they screwed up on our—our numbers again.

Fred Haise (LMP)

Zero out the needles; we're heading that way, and then we'll stop and talk about it.

Jim Lovell (CDR)

No. Pitch is 83. Pitch should be up here. … … What's the number, 552?

Fred Haise (LMP)

Pitch should be 83 degrees. …

Jim Lovell (CDR)

Roll 232; that's a long way to roll, … yaw is 62 …

Jim Lovell (CDR)

Okay. What's that read; there's 180.

Jim Lovell (CDR)

… is over here. Houston, 13.

Jim Lovell (CDR)

There's something screwed up on our burn attitude. We're not getting the proper readings on the ball and the needles are centered. I'm not too sure what's wrong. Let's go through this procedure again.

Vance Brand (CAPCOM)

Okay. Stand by 1. Let us look at it.

Fred Haise (LMP)

— angles you gave us, Vance, aren't correlating the VERB 49 numbers.

Vance Brand (CAPCOM)

Okay. We'll check into it.

Jim Lovell (CDR)

We know the ball is good. Why don't we just get a 40?

Fred Haise (LMP)

You better watch out; it's heading that way.

Vance Brand (CAPCOM)

Okay, Jim. To answer your last question, do you have PGNS checklist page 57 handy?

Jim Lovell (CDR)

Right, we do. I'll check it.

Vance Brand (CAPCOM)

As soon as you open up to that, I'll explain it.

Fred Haise (LMP)

Okay. Go ahead, Vance.

Vance Brand (CAPCOM)

Okay. Under VERB 49, crew-defined maneuver, the flashing 0622 are the angles that we gave you that were loaded. The flashing 5018 actually represents FDAI angles, and so what you read on 5018 should —

Vance Brand (CAPCOM)

— should not correspond with NOUN 22.

Fred Haise (LMP)

Yes. We appreciate that, Vance. It's just that right now we're trying to follow center needles that appear to be possibly taking us away from the place we know we want to be in the ball.

Vance Brand (CAPCOM)

Okay, You're tending toward the gimbal lock area again. Heads up.

Vance Brand (CAPCOM)

13, request you put in the POWER AMPL circuit breakers so that we can take a look at your angles.

Vance Brand (CAPCOM)

Thank you. And now high bit rate.

Vance Brand (CAPCOM)

Okay, 13; we're getting your high bit rate now and taking a look at your angles.

Vance Brand (CAPCOM)

Okay, Jim, we just took a look at your angles, and you're looking good here. Your PGNS is looking good. We can't yet explain the attitude error needle thing, but I suggest you continue on in your maneuver.

Jim Lovell (CDR)

Roger. Okay. We've just about got roll.

Vance Brand (CAPCOM)

13, Houston. We see you now in the AUTO maneuver. How are your error needles looking now?

Jim Lovell (CDR)

Okay. They look like they are working their way in, Vance.

Vance Brand (CAPCOM)

Okay. You think maybe they are working right now?

Jim Lovell (CDR)

Yes. Because we got a 270-degree roll, our pitch and yaw needles are reversed.

Fred Haise (LMP)

Say, how do you read, Vance? …

Vance Brand (CAPCOM)

Fred, you are starting to fade out. Request AFT OMNI, OMNI AFT.

Fred Haise (LMP)

Okay. You've got AFT OMNI.

Jim Lovell (CDR)

Okay, Houston; Aquarius. We appear to be there—at the burn attitude. And now do you want us to change the DAP?

Vance Brand (CAPCOM)

Roger, Jim. We have a procedure to give you for widening the deadband to 5 degrees for the PTC in the next 3 or 4 hours, if you're ready to copy.

Vance Brand (CAPCOM)

Okay. VERB 21, NOUN 01, ENTER; 3011, ENTER; 44, ENTER. Now, that's the procedure for widening the deadband to 5 degrees with the DAP. Later on, prior to the burn, you would return the deadband to 1.4 degrees, and if you're ready to copy, I'll read you that.

Vance Brand (CAPCOM)

Okay. To return the deadband later to 1.4 degrees: VERB 21, NOUN 01, ENTER; 3011, ENTER; 200, ENTER. Over.

Fred Haise (LMP)

Okay, Vance. To widen the deadband, we'll enter a VERB 21, NOUN 01, ENTER; 3011, ENTER; 44, ENTER. Before the burn to go back to narrow deadband, it's VERB 21, NOUN 01, ENTER; 3011, ENTER; 200, ENTER.

Vance Brand (CAPCOM)

Roger, Readback correct.

Jim Lovell (CDR)

And, Houston, I'll guess we'll do this PTC in yaw, and do you want them all powered down?

Vance Brand (CAPCOM)

Okay, that's affirm. You'll be doing the PTC in yaw, and we'll give you a call at each time you change yaw—yaw attitude. Aside from that, request low bit rate off; then DOWN VOICE BACKUP OFF; then POWER AMPL OFF; and then FDAI OFF.

Fred Haise (LMP)

Okay, Vance. On the power down, we go low bit rate; DOWN VOICE BACKUP, we'll pull the POWER AMPL breaker; and we'll power down the FDAI and the AC.

Vance Brand (CAPCOM)

That's affirm. And the AOT, too.

Jim Lovell (CDR)

Okay, are you all set for old a -

Fred Haise (LMP)

Okay, Houston; Aquarius. How do you read DOWN VOICE BACKUP?

Vance Brand (CAPCOM)

Reading you loud—loud and clear now, Fred.

Jim Lovell (CDR)

Oh, Vance, do you want to stay in this attitude for a certain length of time before we start maneuvering?

Vance Brand (CAPCOM)

Roger. Jim, we'll keep you there for about an hour, and then we'll have our first 90-degree rotation.

Jim Lovell (CDR)

Okay. How wide do I make the deadband?

Jim Lovell (CDR)

… the other OMNI's in.

Fred Haise (LMP)

Yes. My forward OMNI is in.

Vance Brand (CAPCOM)

Apollo 13, Houston. Forward OMNI should be best.

Jim Lovell (CDR)

I don't see why the hell he …

Fred Haise (LMP)

I know. I don't know. I don't know where that 5 degrees …

Jim Lovell (CDR)

Oh-h. … that thing against the …

Jim Lovell (CDR)

I'm just going to try and close my eyes for a little.
