Spacelog Apollo 13

Verify ACS STATUS switch, OFF. That's an addition.

Do you mean, under IVT to the LM, number 4, RCS SYSTEM A/B-2, QUADs 4, AUTO? That 4?

That's affirm. Yes. It's the—the only 4 on that page 24 and it's a—presently has after it RCS SYSTEM A/B-2, QUADs, 4, to AUTO. Under that put —

Roger.

— put verify AGS STATUS switch to OFF.

Okay. Verify AGS STATUS switch OFF.

Okay. At the bottom of the page—Okay. You already have that. MODE CONTROL, both, OFF.

Okay. Next, page 26, circuit breakers.

Okay. Go ahead.

Okay. First row is okay as is. Second row, under FLIGHT DISPLAYS, GASTA should be closed.

Okay.

Under AC BUS A, close GASTA.

Okay. GASTA FLIGHT DISPLAYS and AC BUS A will be closed.

Roger. That's all on the second line. Now the third line, under STABILITY and CONTROL, ATCA (PGNS) to closed.

Okay. ATCA (PGNS) to close.

That's all on that line. Fourth line, near the right side, LGC STANDBY to close. And —

Wait a minute. You mean LGC/DSKY.

LGC/DSKY. I'm sorry.

Okay.

And IMU OPERATE, close.

Okay. IMU OPERATE, close.

Okay, Vance. IMU OPERATE, close.

That's correct. Okay. Fourth row is okay as is. Now we would like to add—add in a late arrival to row two. Under —

Go ahead.

Under FLIGHT DISPLAYS, MISSION TIMER, closed.

Okay. FLIGHT DISPLAYS, MISSION TIMER, closed. We can look at the ghosties right to the end.

Yes, that's right. Okay. That's all for that page, Fred. That should add up to six circuit breakers all closed, on that page.

Vance, Jim.

Go ahead, Jim.

Have we looked seriously now at just the essential things required to make a safe LM jettison? We're not—I don't think we have the time to really do any engineering data that people might want to look at as this thing goes into the atmosphere.

Well, Jim. I—I think that that was what everybody aimed for, and people down here feel that it's the essentials, that it's what you need.

Well, we'll do everything you think is essential, but I just don't want to be throwing switches at the last minute. What we're really thinking about, getting that command module in good shape.

Hey, Jim. This is Tom. The only reason we're bringing up the PGNS is to have another reference system just to control the LM when you jettison the thing. Over.

Okay. Okay, Tom. It's—I thought the—an AGS ATT HOLD would have been sufficient for this, when we first thought about this.

Yes. I agree. But we decided just in case we have any glitch with the AGS, we want to make sure we get that LM off in a good shape. And I agree with you on keeping out all the garbage on it.

Okay, Tom.

Hey, would you like to have —

Good night.

Would you like to have us play you some guitar music to put you to sleep?

(Laughter) Oh, you know how to get to a guy.

We'll even have a 12-string guitar for you, Jimbo.

Okay.

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.
