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.
- 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?

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.
