Jim Lovell (CDR)

Wait until I get PTC going first, Vance, then we'll give it to you.

Jack Swigert (CMP)

Okay, Vance. We're P00 and ACCEPT. The computer's yours.

Jack Swigert (CMP)

You know, somehow, everytime I do a set of P23s, you guys uplink me a state vector. I don't think I do too well.

Jack Swigert (CMP)

I could get a complex.

Vance Brand (CAPCOM)

No. You know—you know how the FIDOs are. They like to load in their own data, no matter what.

Jack Swigert (CMP)

But our state vectors take into account the waste water dumps.

Vance Brand (CAPCOM)

Apollo 13, Houston. It's your computer again.

Vance Brand (CAPCOM)

And as a matter of interest, understand that the downrange comparison between the MCC and the computer is within 35000 feet, and that's on the last sighting, which people think is pretty good.

Jack Swigert (CMP)

Okay. Maybe that gives us a little more confidence that if we had to do P23s on the way home, we'd make it.

Vance Brand (CAPCOM)

Just info on your PTC, Jim. It's looking very good. Just—excursions in pitch and yaw are very low.

Jim Lovell (CDR)

Okay, thank you. And we're going to change another lithium hydroxide canister now.

Jack Swigert (CMP)

And, Vance. Has FIDO come up with any observations on the trajectory?

Vance Brand (CAPCOM)

Well, a minute ago, he said that to tell you that he was pacified now after your past comments on his trajectory and so forth, and he hadn't seen any waste water dumps or anything and he's pretty happy.

Jack Swigert (CMP)

Okay. I just wondered if we're going to need any more midcourse.

Vance Brand (CAPCOM)

He says, seriously, it's looking probably like you won't have any more.

Jack Swigert (CMP)

Hey, that's real fine.

Vance Brand (CAPCOM)

FIDOs never guarantee anything, however.

Jack Swigert (CMP)

Houston, 13. I have the onboard read-out, if you're ready to copy.

Jack Swigert (CMP)

Okay. BAT C 37, PYRO BAT A 37, PYRO BAT B 37, RCS A 97 percent, B 97 percent, C 96 percent, D 97 percent.

Vance Brand (CAPCOM)

Roger. We copy that. Thank you.

Vance Brand (CAPCOM)

Jim, just an item for you and Fred to be thinking about in case you haven't been briefed on this, something that's now being talked about a little bit. These conservative people would like to have you read the SHe tank pressure when you go into the LM for the LM familiarization at 58 hours. If there's no midcourse-3, and it looks like there's a good chance that there will not be, why, they might want to move the LM familiarization up from 58 to 55 hours. Over.

Jim Lovell (CDR)

Okay. If we don't have a midcourse-3, then we'll probably move LM FAM up to 55 hours, in which case we'll go in there and read SHe tank pressure.

Vance Brand (CAPCOM)

Roger. Along with the other FAM stuff, and it's not certain that we want to do this, it's just being talked about, so this is just the information for you.

Jim Lovell (CDR)

Okay. This is beginning to sound like the SIM that we ran not too long ago.

Vance Brand (CAPCOM)

I don't think it will be a very big deal.

Vance Brand (CAPCOM)

This is Houston. Go ahead.

Jack Swigert (CMP)

Okay, Vance. Our LM/CM DELTA-P is 0.9.

Vance Brand (CAPCOM)

Are you guys hacking into your presleep checklist yet?

Fred Haise (LMP)

Oh, we just finished eating and cleaning up a bit afterwards. Jim's going around collecting debris off of all the inlet hoses. And, I guess you might say we're kind of thinking about getting ready to go to sleep.

Vance Brand (CAPCOM)

Well, I hope you had a good meal.
