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.
