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?
- Jim Lovell (CDR)
-
Okay. We wrote it as roll, pitch, and yaw.

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.
- Jim Lovell (CDR)
-
I'm going to roll it.

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.
