Okay. We PRO on—after entering the 200. We'll get a flashing 0688. We then load the Sun unit vectors for 74 hours, which are R1 plus 5—correction, plus 45498, R2 plus 19024, R3 plus 08250.
-
Charlie Duke
-
Roger. That's good, Fred-o. And that'll bring you to step 8, and you get a flashing 5018 when you PRO on the NOUN 88. Okay. At 5018, we want to do an AUTO maneuver to—to the attitude, so just do the—the PRO with the GUIDANCE CONTROL, PNGS; MODE CONTROL, PNGS, AUTO; and we'll take this attitude. Now, that's going to put us at—at attitude for the Sun check. Now, we're being a 1.4-degree deadband in this program in a docked configuration; so, to help you out, you could call VERB 62 to get your needles—and it—when the needles go through zero or null out and—in that deadband—then you take a look in the AOT and see how close the Sun is. And we want within plus or minus 1 degree. Over.
-
Fred Haise (LMP)
-
Okay. So we PRO on the NOUN 88, and we end up with a flashing 5018; and you want an AUTO maneuver here rather than using the TTCA, so we PRO with GUIDANCE, PNGS; MODE CONTROL, AUTO. We've got a 1.4-degree deadband with a VERB 62 will give us the needles to try to zero them in and, at that time I look through the AOT and, if it's like Apollo 11 Sun check, all we've got to have is the Sun somewhere in the—out there somewhere on the Sun as it passes. Is that correct?
-
Charlie Duke
-
I think that's a little tight; that's about a quarter degree. We can go a little bit out of that. Stand by 1. Fred, we'll get you an answer on that one. And also, if you'll stand by, we'll give you a DAP load for this maneuver. Over.
-
Charlie Duke
-
Aquarius, Houston. Fred-o, on that—to pass that check, the Sun is at—will subtend an arc of one-half degree in the AOT, so you can be two diameters off and still pass the check. Over.
-
Charlie Duke
-
That's affirmative. And we want you to maneuver with a DAP of 0.2 of a degree a second. Over.
-
Charlie Duke
-
Roger. Now, if we pass that check, you can just terminate P52 right there, and we'll give you an attitude to go to a burn attitude, and from this we can get a star check. If you don't pass, we'd like you to do an alinement at 75 hours. And, if you're ready to copy, we have some Sun half-unit vectors and some Earth half-unit vectors at 75 hours. Over.
-
Charlie Duke
-
Roger. First with the Sun; for X, plus 45483; for Y, plus 19053; for Zebra, plus 08262; Earth half-unit vector at 75 hours, plus 32120, minus 34155, minus 17370. Over.
-
Fred Haise (LMP)
-
Okay. Sun half-unit vectors: R1 plus 45483, R2 plus 19053, R3 plus 08262; Earth half-unit vectors: R1 plus 32120, R2 minus 34155, R3 minus 17370.
-
Charlie Duke
-
Roger, Fred-o. Good readback. Now, on the Earth, we estimate it—if you have to do this alinement, that the Earth will be about a 2-degree Earth. And it'll be approximately three-quarters lighted. Now, to mark on the Earth, we'd like you to take an imaginary line between the horns of the crescent and mark midway between the horns. Over.
-
Fred Haise (LMP)
-
Okay. We got a 2-degree Earth that's three-quarter lighted, and we're to imagine a line between the horns of the Earth and mark right in the center of that line.
-
Charlie Duke
-
That's affirmative. Now, on—on this star check—correction, the Sun check, Fred, at—On the 5018, I got some FDAI angles for you if you're ready to copy. Over.
-
Fred Haise (LMP)
-
Okay. You're talking about the check at 74 hours GET, right?
Expand selection up Contract selection down Close -
Charlie Duke
-
Roger. Okay. At 74 hours when you start this maneuver, the 5018 should look like R1 of 2703 degrees, pitch R2 is 0903, and R3 of 2908. Over.
-
Charlie Duke
-
Roger. That's good readback. Now, we got one more procedure for you; and, right now, we got the rendezvous radar stowed and we won't be able to see anything out of detent 2, so we'd like you to position the radar to 0283; and we have a procedure for that. And we'd like you to do that right before you get the attitude. Over.
-
Charlie Duke
-
Aquarius, Houston. On those 5018 angles we had at 74 hours, Fred, that was based on a VERB 49 to this attitude, and they will be incorrect for the two axis maneuvers, so you can just scratch them. Over.
-
Fred Haise (LMP)
-
Okay. You're saying the angles you gave me for the 5018, that was for a VERB 49, so they won't be good for the 5018, and we should scratch them.
-
Charlie Duke
-
That's affirmative. Okay. If you're ready to copy, I've got this rendezvous radar procedure. Over.
-
Charlie Duke
-
Okay. It's about a 10-stepper, but real easy. Okay. On CB 16, EPS INVERTER 2, close. CB 11, AC BUS A BUS TIE INVERTER 2, close. Panel 14, verify INVERTER switch 2. CB 11 RENDEZVOUS RADAR 2, close. RENDEZVOUS RADAR, release. RENDEZVOUS RADAR to LGC on panel 3. Are you with me? Over.
-
Charlie Duke
-
Okay, Fred. Good show. Step 6: VERB 41 NOUN 72 ENTER, plus all balls, plus 28300. Step 7: Monitor movement with VERB 16 NOUN 72. Step 8: CB 11 RENDEZVOUS RADAR 2, open. Are you with me? Over.
-
Charlie Duke
-
I got one more for you. You'll copy this and give me it all on the readback. Okay. Once you get the attitude and you want to use the—you want to get the AOT lamp, we got to go CB 16 EPS INVERTER 2, close; CB 11, AC BUS A AOT LAMP, close. After the P52, you can open CB 16 EPS INVERTER 2, and open CB 11 AC BUS A AOT LAMP and AC BUS A BUS TIE INVERTER 2. Over.
-
Fred Haise (LMP)
-
Okay. Let's see if I got it all. For rendezvous radar parking: first of all we want CB 16 EPS INVERTER 2, closed, CB 11 AC BUS A BUS TIE INVERTER 2, closed. Then on panel 14, verify INVERTER 2 selected. And CB 11 RENDEZVOUS RADAR 2 closed, both breakers. Then we are to pull the RENDEZVOUS RADAR RELEASE handle. On panel 3, we then want RENDEZVOUS RADAR to LGC. A VERB 41 NOUN 72 ENTER with plus all zips, plus 28300 in registers 1 and 2. GO on that. Then we monitor movement with the 16 72. After it gets parked, CB 11 RENDEZVOUS RADAR 2 open, followed by VERB 44 ENTER. And CB 16 EPS INVERTER 2 open. Now, when it comes time for the alinement to get an AOT lamp, CB 16, EPS INVERTER 2 closed, CB 11 AC BUS A AOT LAMP closed, and after the alinement is completed at CB 16, EPS INVERTER 2 open, CB 11 AC BUS A AOT LAMP open, CB 11 AC BUS A BUS TIE INVERTER 2 open.
-
Charlie Duke
-
Good readback, Aquarius. We'll—To get those needles on the VERB 62, we got to power up the commander's FDAI. We'll have that procedure for you shortly. Over.
-
Charlie Duke
-
Is the question, “Have we run a—an alinement in the docked configuration?” That is affirmative.
-
Jim Lovell (CDR)
-
Okay. Did you have any trouble controlling the vehicle, and what techniques did you use?
-
Charlie Duke
-
Briefly, to control pitch and roll, use the TTCA, as we've practiced; for yaw you can use the ACA. Over.
-
Jim Lovell (CDR)
-
Okay. You have no special techniques going back and forth between the yaw and the X and Y lines. Over.
-
Charlie Duke
-
Not right now, Jim. Dave Scott's been running these things and we'll get them up to you shortly. Over.
-
Charlie Duke
-
We think the alinement's going to be okay, so we don't have to do this P52 fullup alinement. We think the check is going to be okay. Like to remind you since you are in ATT—if check does not pass, since you are in attitude for the Sun, that we'd—We want the Sun half-unit vectors first. Over.
-
Jim Lovell (CDR)
-
Okay, Houston. It's been over an hour since we did our last PTC. You want us to do another one now?
-
Charlie Duke
-
Aquarius, Houston. We'd like you to go ahead and yaw 90 for the PTC. Keep a close eye out on your middle gimbal angle. You're about 30 degrees from gimhal lock, and we'll call you an OMNI switch halfway through the maneuver. Over.
-
Fred Haise (LMP)
-
Okay. And, Houston, Aquarius. You might know when you've had enough ranging so we can get the power amp back off again.
-
Charlie Duke
-
Roger, Fred-o. We got one more procedure, and we can shut it down, and that's to get the needles and the FDAI for this maneuver. That 5018 could take you to gimbal lock, and we think it's a good idea to power up the commander's ball. We've got a four-stepper, if you're ready to copy. Over.
-
Charlie Duke
-
Okay. Verify that you got AC power, in other words, the INVERTER 2 selected and the BUS TIE INVERTER 2 AC BUS A closed. We'll be under FLIGHT DISPLAYS, GASTA closed, commander FDAI, closed. On the AC BUS A, CBs GASTA closed, CONBIANDER FDAI closed. Over.
-
Fred Haise (LMP)
-
Okay. It's verify we have AC, which is panel 16 INVERTER 2 closed. CB INVERTER 2 closed. Then on panel 11 under FLIGHT DISPLAYS, we want the GASTA and the COMMANDER's FDAI breakers closed. Also under panel 11, AC BUS A GASTA and COMMANDER's FDAI breakers closed.
-
Charlie Duke
-
Aquarius, Houston. After the OMNI switch, we would like you to get the ranging off, the VOICE switch to DOWN VOICE BACKUP, and the POWER AMP CB on 16 open. Over.
-
Fred Haise (LMP)
-
Okay. After the OMNI switch, we'll get the POWER AMP off and go back to DOWN VOICE BACKUP FTA and the RANGING off. It's your call.
-
Charlie Duke
-
Fred-o, we got about 2 minutes to the OMNI switch. You can go ahead and power the RANGING down and and the DOWN VOICE BACKUP, and we'll give you a call on OMNI switch. Over.
-
Fred Haise (LMP)
-
Okay. Vance, if Buzz or Neil are around you might ask them if they had to use the AOT lamps to shoot the Sun like they did on 11.
-
Vance Brand (CAPCOM)
-
Fred, breaking in. You're very weak. Understand if Buzz or Neil are down here, you'd like to ask them if they used the AOT lamp to what? Over.
-
Jim Lovell (CDR)
-
To see the Sun, Vance. It might be possible to see the reticle without even having the light on.
-
Vance Brand (CAPCOM)
-
Oh, I see. See if it's possible to see the reticle without the light on. Okay. We'll make a check. And one other thing, you might move that rendezvous radar antenna to park any time now. You can start any time you want.
-
Vance Brand (CAPCOM)
-
Jim, Neil is here. He advises that you will not need the lamp on for the Sun check but that you will need it on for the Earth check. Over.
-
Jim Lovell (CDR)
-
Okay. Let me—First of all, let me see how we're doing here. That's going down. That's better. That's coming up. That's right. Let's—Okay. Let's park the radar. How—How long is it going to take?
-
Fred Haise (LMP)
-
Not too long. Okay, INVERTER 2 … Here, hold the light for me, Jim. Right here on the … panel. Hold it still. … AC BUS A BUS TIE.
-
Vance Brand (CAPCOM)
-
Roger. One correction. We think that the cheapest way for you to maneuver to change attitude is with minimum pulse ACA. That's to do the star mark.
-
Jim Lovell (CDR)
-
We had—Okay. As soon as possible we'll get that star data … we can get to maneuver attitude by using TTCA.
-
Jim Lovell (CDR)
-
And, just out of curiosity, we got rid of the radar very nicely. It's hanging right in the middle of the—the forward digit is the docking light on the command module. Can you believe that? I don't think it will hurt our Sun check, but it'll sure make P52 …
-
Fred Haise (LMP)
-
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.

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.
