Charlie Duke (CAPCOM)

Hello, Apollo 11, Houston. We'd like P00 and ACCEPT. We have a DELTA-H update for you. Over.

Michael Collins (CMP)

All right, Charlie. Stand by one.

Michael Collins (CMP)

Houston, Apollo 11. P00 and ACCEPT.

Charlie Duke (CAPCOM)

Apollo 11, Houston. We got the load in. The computer's yours. Over.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. We'd like for you to stir up the CRYO's now. Over.

Michael Collins (CMP)

Houston, Apollo 11. Roger.

Neil Armstrong (CDR)

Houston, Apollo 11. We're completed in the LM. We're closing up the hatches and the probe and drogue back in.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. We're standing by to watch your startup on the PTC at any time. You can start off at the VERB 49. Over.

Neil Armstrong (CDR)

Wilco. We're just finishing up the probe and about to close up the hatch here. We're going to be a couple of minutes late, probably, getting started in the PTC.

Charlie Duke (CAPCOM)

Roger. No sweat, 11. We're standing by. Over.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. Mike, there's no wait required. Where rates are steady, you can proceed on. Over.

Michael Collins (CMP)

The tunnel's all taken care of, the drogue, probe, and hatch all back.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. We have some new additions to your alternate contingency checklist if you would break that out. Over.

Neil Armstrong (CDR)

Okay, Houston. 11's ready to copy.

Charlie Duke (CAPCOM)

Roger, 11. If you'll turn to page F2-22. Over

Charlie Duke (CAPCOM)

Roger, Neil. Under column 1—that's column Lima, line 06. The new data is 00001. Line 07, the new data is 02134. Over.

Neil Armstrong (CDR)

Okay. I have in F2-22, column Lima, item 6, 00001; item 7, 02134.

Charlie Duke (CAPCOM)

Roger. That's correct. Thank you much. Out.

Charlie Duke (CAPCOM)

11, Houston. For your information, those two entries are an update to your DELTA-H that we have already uplinked into the CMC. Over.

Michael Collins (CMP)

What was I marking on, Charlie? About an 18-kilometer line, or what?

Charlie Duke (CAPCOM)

We—Our update puts you to—the DELTA-H to 35 kilometers, Mike. Over.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. We've got some switch positions for you for the high gain. Over.

Charlie Duke (CAPCOM)

Roger, Buzz. Select Bravo, OMNI, HIGH-GAIN TRACK to MANUAL; BEAM, WIDE. Over.

Buzz Aldrin (LMP)

Okay. Bravo, OMNI; TRACK, MANUAL; and BEAM, WIDE.

Charlie Duke (CAPCOM)

Roger. And your high-gain angles are minus 50 on the pitch, 270 on the yaw. Over.

Buzz Aldrin (LMP)

Okay. Going there now.

Charlie Duke (CAPCOM)

Hello, Apollo 11. Houston. We have some updates and some things we'd like to talk to you about, if you aren't in the middle of your meal. If it's convenient anytime for you, we're ready with some updates. Over.

Neil Armstrong (CDR)

What—What are the updates going to apply to?

Charlie Duke (CAPCOM)

Roger. We have a couple of changes on the LM mission rules NO GO for your NO GO card, Neil. One slight change on the APS/DPS fuel and TEMP pressure card, and we have a change to the procedure for the secondary radiator leak check, which is to be formed at—performed at 71 hours tomorrow, and also some indications that we have a couple of landing site obliques stowed in the wrong place. Over.

Neil Armstrong (CDR)

Okay. Is any of those in the flight plan? The secondary radiator, for example?

Charlie Duke (CAPCOM)

That's affirmative. The secondary radiator leak check is called out in the flight plan at 71 20. That procedure is listed in your launch operations book on page 2 9, L2 9. We'd like to change that procedure. Over.

Michael Collins (CMP)

Charlie, on the secondary leak check, just read it verbatim like you want, and I'll copy directly into the flight plan and not fool around with the checklist.

Charlie Duke (CAPCOM)

Roger. That's fine. If you're ready to copy, stand by.

Michael Collins (CMP)

Ready to copy on the leak check.

Charlie Duke (CAPCOM)

Roger. It's monitor secondary accumulator quantity. Step 2 is secondary glycol to radiator valve, NORMAL for 30 seconds, then BYPASS. If no decrease in secondary accumulator quantity—Are you with me?

Charlie Duke (CAPCOM)

Okay. If no decrease in secondary accumulator quantity, secondary glycol to radiator valve to NORMAL. Next step, secondary coolant loop pump, AC 1 or AC 2. After 3 minutes, verify glycol discharge secondary pressure 39 to 51 psig. Also verify secondary EVAP out TEMP has changed. Next step, secondary coolant loop pump, OFF. Secondary glycol to radiator valve, BYPASS. That ends the procedure. Over.
