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

And be advised, Vance, that we are getting several echos in our COMM downlink here.
- Vance Brand (CAPCOM)
-
Jim, request you give us high bit rate now. We might be able to fix you up on the 120 antenna.
- Vance Brand (CAPCOM)
-
Fred, we can't lock up on your high bit rate. Request you go back low bit rate.
- 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)
-
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)
-
It's not quite centered, but it's about a diameter, a little bit less than a diameter, just to one side.
- 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.
- 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.
- 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.
- 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.
- 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)
-
Okay. Stand by on that, Fred. First, let me read up your VERB 49 attitude, if you are ready to copy.
- 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)
-
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.
- Jim Lovell (CDR)
-
Let me see. No, that's yaw, pitch, and—Okay. Everything's … … That's 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)
-
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.
- 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.
- 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, 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)
-
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)
-
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, Jim. To answer your last question, do you have PGNS checklist page 57 handy?
- 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 —
- 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)
-
13, request you put in the POWER AMPL circuit breakers so that we can take a look at your angles.
- 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.
Expand selection down Contract selection up - Vance Brand (CAPCOM)
-
13, Houston. We see you now in the AUTO maneuver. How are your error needles looking now?
- 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.
- 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.
- 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.
