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.
