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.

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.

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.

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.
-
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.

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.
