Okay. I read back: monitor secondary accumulator quantity; secondary glycol radiator valve, NORMAL for 30 seconds, then to BYPASS. If no decrease in secondary accumulator quantity, secondary glycol to radiator valve to NORMAL. Secondary coolant loop pump, AC 1 or 2. After 3 minutes, verify glycol secondary discharge pressure 39 to 51 psig. Verify secondary evaporator outlet TEMP has changed. Secondary coolant loop pump, OFF. Secondary glycol radiator valve to BYPASS. And what's the reason for the change, Charlie?

Charlie Duke (CAPCOM)

Roger. Stan is concerned that our present procedure as shown in the checklist does not really flow glycol through the radiator, and it—They want to verify that we do not have a plugged secondary radiator. Over.

Negative. This is the procedure that they came up with. It's just a check, Mike. Everything's looking great to us. Over.

Charlie, we'll get back with you on these other changes in a few minutes. Okay?

Okay, Buzz. The first item is that we have indications that your landing site obliques are not in the proper position. If you'll check, we think that the intermediate scale landing site oblique is stowed in the CSM lunar landmark book. We think that the large scale landing site oblique is stowed in the back of the LM lunar surface map book. Over.
-
Charlie Duke (CAPCOM)
-
Roger. According to our stowage list the—the landing site oblique should be in the transfer bag. In—But in the backup set of data, the intermediate scale oblique is in the CSM lunar landmark book, and the large scale oblique is in the back of the LM lunar surface map book; and that's the reason we think that they might be not where you think they are. Over.
-
Buzz Aldrin (LMP)
-
Okay. We've got three obliques. The last one is one I asked for recently. It's just a blow up of the second one. The first one is one that's got dotted lines on it, indicating horizon view and 50-degree LPD; and all three of those are in the transfer book. Over.

Roger. Fine. We were wrong in our—in our backup set. We had those out of place. Looks like the onboard data's good. We just wanted to let you check on that one. We have an update on the APS/DPS fuel card that you place on the panel. It's a typo error. If you'll break out that little card, we've got the—correct that typo error. Over.
-
Charlie Duke (CAPCOM)
-
Roger, Buzz. Under the DPS column on the pressure side, you go down to the fourth item, says pressure greater than 150 PTCA should be greater than 65 percent. Over.
-
Buzz Aldrin (LMP)
-
Okay. That's greater than 1.8 but less than 65 and greater than 150 for greater than 65.
-
Charlie Duke (CAPCOM)
-
And we have three items on the mission rules NO-GO card, if you're ready to copy those. Over.
-
Charlie Duke (CAPCOM)
-
Roger, Buzz. First entry's on the EPS under AC bus A. The line extends all the way to high gate. Actually, the line should read—at DOI it would be NO-GO AC bus A. After that the NO-GO would be both buses. So if you will just pencil in both buses from PDI through high gate, it'll be correct for that line. Over.
-
Charlie Duke (CAPCOM)
-
That's affirmative up until high gate. You can stop at the line in front of the column “5 minutes to low gate”. Now the next line is under the G&C PGNS, pitch and roll GDA's. You can scratch that line completely. Over.
-
Charlie Duke (CAPCOM)
-
Okay, Buzz. Last entry is down under RCS, and it's a typo error under the three—in the line “three axis attitude control”. If you proceed to the right at PDI plus 05, you'll see one axis. The line goes all the way to low gate to touchdown. That's incorrect. The line should stop under “5 minutes to low gate”. Over.
-
Charlie Duke (CAPCOM)
-
That's affirmative. That completes that card. The rest of the updates are just really for your information based on our 58 hour platform—look at the platform. We are really good shape. Your GYRO's have almost no drift in them since—plotted update we were looking at X of a minus 2.24 … Y of point plus 0.87, Z of minus 0.11. Since the update, which was based on the 52 hour P52, I believe, we gave you an X drift of plus 0.79, yaw of plus 1.06, Z of plus 0.02 … I can see the difference between the 52 hour and the 57 hour alignments were—did not really give us enough time to get a real good or completely valid update on the drift check. So we're real satisfied with the way the GYRO's are looking. The PIPA's are looking great also. We are in real good shape with those, too. Over.
-
Neil Armstrong (CDR)
-
Okay. Loud and clear. You cut out when you were talking about the platform—something about 52 hours and after that, we never heard you again.
-
Charlie Duke (CAPCOM)
-
Roger. Guess we were changing antennas. Stand by. That's affirmative, 11. We were swapping antennas on you down here. Basically the word is that we have a real good platform, very small drift on the GYRO's, and very small drift in the PIPA's. Over.
-
Neil Armstrong (CDR)
-
Roger. Thank you. And I would like to have a few words of clarification if you will give them to me on the RCS … what that change of pitch may mean.
-
Charlie Duke (CAPCOM)
-
Copy. A few words of clarification on the RCS? Oh. Roger. The update there, Neil, you are speaking of about the one axis down to 5 minutes of low gate?
-
Charlie Duke (CAPCOM)
-
11, Houston. On the RCS, what we are saying is that if we lose control about one axis prior to low gate, we would recommend an abort. This would require a—a loss of—of two distinct jets which is not very probable, but that is what we are recommending. After low gate we would continue on. We would recommend that we continue on to attempt a landing. Over.
