Spacelog Apollo 13

Okay, Fred. Page 28.

Okay. I'm looking at panel 16 now.

No—No changes to panel —

…

No changes to panel 16.

Okay. I'm on 28 now.

Right. Okay. At the top of the page, under step 4, just above “VHF/S-band activation,” put in, “Delete POWER AMP and LGC.” These are caution lights.

Okay. You mean delete PREAMP.

I'm sorry. PREAMP and LGC.

Okay.

Okay. Under “VHF/S-band activation and checkout,” step 2, we have changes to the COMM as fellows.

Go ahead.

Okay. Scratch—Scratch out the DOWN and DOWN VOICE. That leaves—That'll give you VOICE.

Okay. That's the way we had it last time.

Okay. And, we'd like to insert RANGING.

Okay. Instead of OFF/RESET put RANGING.

That's correct.

Okay.

Okay. Under “PGNS turn-on,” add in steps 1 and 2 again, which are NO ATTITUDE light off, VERB 96 ENTER, and set EVENT TIMER.

Okay. Steps 1 and 2 back in.

That's affirm. And underneath “Set EVENT TIMER,” add the following: VERB 25 NOUN 07, ENTER; 1257, ENTER.

Okay. Go ahead, Vance.

Okay. If you got the 1257, ENTER, then 252, ENTER and ENTER.

Okay. After event, set EVENT TIMER, it's VERB 25 NOUN 07, ENTER; 1257, ENTER; 252 ENTER; ENTER.

Roger. And this activates your upfiring jets.

Say the last again, Vance.

Roger. What this does, Fred, is activate upfiring jets.

Oh, okay.

They're all—actually, all vertical jets.

Okay. I got it.

Okay. Next, same page, under “DAP set gimbal drive,” go to step 2. Okay. Add in after NOUN 46, 32021.

Okay. 32021.

Okay. Proceeding on down below the NOUN 47, to the PROCEED, insert VERB 34, ENTER, after the PROCEED. And that would come before the NOUN 48.

Okay. To PRO and then do a VERB 34.

Roger. Okay. We have some noise here, Fred. Stand by a minute.

I switched OMNIs. How's that?

Hey, that helped. Okay. No changes now on 29, 30, and 31. Next page is 32.

Okay. I'm on 32.

Okay. At the very first step above “GUIDANCE CONTROL, AGS,” put in VERB 76, ENTER.

Okay. VERB 76, ENTER.

Okay. Below “GUIDANCE CONTROL, AGS,” the third step should be changed to be MODE CONTROL, both, to ATT HOLD.

Okay. You want MODE CONTROL, both, to ATT HOLD.

That's affirm.

Okay. That's all for page 32, Fred. Next, page 33.

Go ahead.

Okay. Under 4 minutes, minus 4 minutes, add back in MODE CONTROL, both, to ATT HOLD.

Okay. MODE CONTROL, both, to ATT HOLD.

Okay. Two steps below that, add back in TTCA COMMANDER THROTTLE MIN DPS, and add in DPS.

Wait a minute.

Stand by 1.

TTC—Yes. Seems like you should be in JETS, since this is going to be—is this going to be RCS or a DPS burn?

Okay. This will be JETS for RCS and THROTTLE for DPS.

What I don't understand is, what is this MCC likely to be? I thought it was going to be an RCS.

Well, we—We expect that, but we're remaining flexible.

(Laughter) Okay. Okay. I'll put in TTCA THROTTLE MIN for DPS, JETS for RCS.

That's correct. Okay. That's all on page 33. Go to page 34.

Okay. Beneath everything on that page, add in the following. Return to “Entry,—LM PREP” check—return to “Entry, LM PREP” checklist —

Hold on, Vance; I don't understand. We want to delete everything on page 34?

No, that's not correct, Fred. What we wait to do is leave everything the way it is on 34, and add this one comment I'm giving you at the—at the bottom of it.

Oh, okay. Okay. I misunderstood. Okay. Go ahead with your added comment.

Return to “Entry LM PREP checklist.”

Add “EI” —

… turn to—return to “Entry, LM checklist?”

That's affirm. At EI minus 5 hours.

Okay. At EI minus 5 hours. Let me take a look and see how that flows, now.

Okay. And also you have a —

Okay. That would be the LM—the LM preentry procedure. Yes. Okay.

That's correct, and, also on that page, you—from our last correct—or addition exercise, you have a section called “Reestablish PTC.” We'd like to scratch all of that, of course.

Roger.

Stand by 1. Fred, we're polling the room for comments here, any last minute thoughts from people. We'll be right back with you.

Aquarius, Houston.

Okay, Go ahead.

Okay, Fred. Just two changes, comments to what we just gave you. The first is near the front at EI—in the section under “EI minus 2-1/2 hours,” power removal from CM LM umbilical." We'll let you turn to that.

Okay, I'm there at “EI minus 2-1/2 hours, power removal CM LM umbilical.”

Okay. Under LM, we have a step, BAT 2, LOW VOLTAGE, OFF/RESET, than ON. Next we have a step BAT 2, HI VOLTAGE. OFF/RESET, then ON. We request that you wait in between these two steps for us to give you a GO. In other words, we'd like to look and see that all the relays closed and all that sort of thing before you throw BAT 2, HI VOLTAGE, to OFF/RESET, and ON.

Okay, After BAT 2, LOW VOLTAGE, OFF/RESET, I'll—then ON, I'll wait for a MSFN GO before proceeding.

Right-o. Okay. Next, at—Under the section of “EI minus 1 hour and 45 minutes”—No, change that. Correction, “EI minus 1 hour, 35 minutes,” refer to the ECS section, and we have a change.

All right. Go ahead, Vance.

Okay, Jim's right. We should cross out all this stuff with a couple of exceptions. FORWARD DUMP valve, closed, the first step, should remain. All other steps should be scratched, except for the last one, which is OVERHEAD DUMP valve, closed. That leaves two steps.

Okay. Under ECS, we delete all except the first step, FORWARD DUMP valve, close, and step 10, which is OVERHEAD DUMP valve, closed, and leave in verify transfer list.

That's affirm. Leave in what follows, which is verify transfer list and IVT and all that.

IVT, of course, meaning CDR transferring to the CM.

We wouldn't forget it.

Okay, Fred-o. That's—That's the changes. Not quite as extensive as the CSM had, but still pretty long. Any comments or questions to the house here?

No, it looks pretty good to me, Vance.

Okay. Very good. Only other comment, aside from the checklist, we've been watching your descent stage water, and it looks—or your ascent stage water, and it looks real good.
