Spacelog Apollo 13

That's correct. And EMERGENCY CABIN PRESSURE valve to BOTH.

EMERGENCY CABIN PRESSURE to BOTH.

That's correct; and the SUIT DEMAND REGs to BOTH.

SUIT DEMAND REGs to BOTH.

That's correct. Okay, now we're going to panel 5: circuit breaker ECS TRANSDUCERs, PRESSURE GROUP 1 and 2, MAIN A and MAIN B. That's four circuit breakers, closed.

ECS TRANSDUCERs, GROUP 1 and 2, MAIN A and MAIN B, four, to close.

That's correct. Okay, now. Circuit breaker ECS TRANSDUCER, TEMPERATURE, MAIN A and MAIN B, that's two of them, closed.

CB ECS TRANSDUCER, TEMPERATURE, MAIN A and MAIN B, closed.

That's correct. On panel 4: PRIMARY ECS GLYCOL PUMPS, one, to AC 1.

Primary ECS GLYCOL PUMPS to 1, AC1.

That's correct. Okay, then we'll finish going back to the tunnel vent, and verify the LM/CM DELTA-P and make sure it's been holding pressure. And we'll come back again and rehash all of the hatch integrity check and tunnel vent procedures with you. The next thing I want to read off is the EI minus 1 plus 20. We'll go to panel 7: BMAG number 1 POWER to WARM UP.

BMAG number 1 POWER to WARM UP.

That's correct. Then at EI minus 1 plus 10, we'll perform SCS powerup per checklist, page G/2-4.

Okay. Perform SCS powerup per G&C checklist, page 2-4.

That's correct. Okay, on panel 4: SUIT COMPRESSOR NUMBER 2 to AC1.

SUIT COMPRESSOR 2 to IC1.

That's correct. SPACECRAFT CONTROL to SCS.

SPACECRAFT CONTROL to SCS.

Okay. And your MANUAL ATTITUDE switches, as you desire. We're coming up on jettison of the LM, so that's just like separation.

Okay.

Okay. And we'll do a GDC aline.

Okay. Perform a GDC aline.

Okay. On panel 8: ROTATION CONTROL POWER, DIRECT, 1 and 2, MAIN A/MAIN B.

Okay. These are circuit breakers, ROTATION CONTROL POWER, DIRECT, 1 and 2, MAIN A and MAIN B, closed.

Okay, Jack. I was thinking switch. Let me verify that's a circuit breaker, too. I think we have to get both of them.

Okay, there's those four circuit breakers over there, Ken. When you said panel 8, that's what I thought you were talking about. I don't think the circuit breakers are out right now, but why don't we just put—verify the circuit breakers and put the switches to MAIN A/MAIN B.

Okay, that's correct, Jack. Okay, at EI minus 1 hour, we're going to be doing the LM jettison; so just prior to that, we want to do a P47.

Okay, say at about 1 minute prior to LM jettison, huh?

Yes, just something that's comfortable for you.

Okay.

That's correct. Now we're going back to panel 8, and it's SEQUENTIAL, PYRO ARM, two of them, to SAFE.

Okay. SEQ PYRO ARM, two, to SAFE.

That's correct, and go back to P00.

Okay. Go to P00.

All right. And now it's time to configure for single ring.

Okay. Configure for single ring RCS.

That's right, and since you're still an hour from EI, I guess it wouldn't hurt to use MINIMUM IMPULSE or something like that rather than the DAP, at least not until you get closer down. We'll have the DAP loads for you later.

… —

Okay. And as soon as you've gotten yourself all set up with a good control mode, you want to maneuver to the entry attitude.

Maneuver to entry attitude per the pad.

That's correct. And we show EI minus 55, which really means when you get to the entry attitude, we have a sextant star check for you. And that will be on the pad.

Okay. Perform a sextant star check.

Okay. And I want to remind you to park the optics at 90 degrees of shaft.

Okay. Say again why, Ken. I didn't understand that.
