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)

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.
