Roger. We copy that. But there's a greater duty cycle on—There's a good 15 percent duty cycle on the ascent program there, so just go ahead and leave it off. And I have the changes there if you want to get out your surface checklist, and I can go ahead and start giving them to you.
- Ronald Evans (CAPCOM)
-
Okay. Before we start here, request P00 and DATA, and we'll give you some vectors.
- Neil Armstrong (CDR)
-
Okay. And I understand you want us to do a P57 option 3 and then a P22, is that the general idea? Over.
- Ronald Evans (CAPCOM)
-
That's affirmative. So on Surface 50 there, down at the bottom of the page, just after PRO after two recycles, stick in a time of 122 plus 15; do P22 as per PGNS 20 of G&N dictionary. Over.
- Ronald Evans (CAPCOM)
-
Okay. This is going to be for one last vent on the DPS tank there, so at the top of the page just after EPS INVERTER 1, CLOSE, add—Okay, after EPS INVERTER 1, CLOSE, add PROP DESCENT HELIUM REG/VENT CLOSE, and then after STABILIZATION/CONTROL AELD, CLOSE, add PROP DISPLAYS/ENGINE OVERRIDE/LOGIC, CLOSE. Over.
- Ronald Evans (CAPCOM)
-
Tranquility Base, affirmative. Those are just the circuit breakers at that time.
- Ronald Evans (CAPCOM)
-
Tranquility Base, Houston. Did you get those two on the propulsion circuit breakers?
- Ronald Evans (CAPCOM)
-
Okay. Let's go over to Surface 60, and then down the middle of the page, after launch guidance system recommendation from MSFN, then I add the switches there.
- Ronald Evans (CAPCOM)
-
Okay. After launch guidance system recommendation from MSFN, add DESCENT PROPULSION FUEL VENT, OPEN; add DESCENT PROPULSION OXIDIZER VENT, OPEN; add verify talkback gray. Over.
- Neil Armstrong (CDR)
-
Roger. DESCENT PROPELLANT FUEL VENT, OPEN; DESCENT PROPELLANT OXIDIZER VENT, OPEN; verify talkback gray.
- Ronald Evans (CAPCOM)
-
Roger. You got that one, so that'll be the last vent and it will continue venting. Skip over to Surface 61 down there at TIG minus 17.
- Ronald Evans (CAPCOM)
-
Okay, at TIG minus 17, delete CB (11). AC Bus A, RENDEZVOUS RADAR, CLOSE, wait 30 seconds; delete PGNS: RENDEZVOUS RADAR, CLOSE; and then add UP DATA LINK switch to VOICE BACKUP. Over
- Neil Armstrong (CDR)
-
Roger. I have that. We'll leave those two circuit breakers open, and have the UP DATA LINK to VOICE BACKUP; and we'll make the appropriate changes on the following circuit breaker status card.
- Ronald Evans (CAPCOM)
-
Roger. And then you might add a little note down there at the bottom of the page—Note:—This is at the bottom of page 61—Note: Do not use tape meter in PGNS, i.e., do not place MODE SELECT switch to PGNS. Over.
- Ronald Evans (CAPCOM)
-
Okay. That's all the changes we have for the checklist here. I've got some—just some general notes, I'll read to you on P22, and just for some information. Over.
- Ronald Evans (CAPCOM)
-
Roger. We agree wholeheartedly. And while you're starting on that, I'll read—just read these notes on P22. Call P22 possible program alarm 5.6, range greater than 400 nautical miles, and then use the P22 as described on PGNS 20. Take option 1 in NOUN 06, and use the no update mode. The rendezvous radar will lock on at about 25 degrees elevation above the horizon. If 503 alarm occurs, designate fail. Key a PROCEED and allow the rendezvous radar to search for the CSM. And place the range altitude monitor switch in altitude/altitude rate to prevent the tape meter from driving into the stops. And press on.
- Ronald Evans (CAPCOM)
-
Roger, Columbia. We'd like a CRYO stir in all four tanks and the standard 1 minute. Over.
- Buzz Aldrin (LMP)
-
Roger. ERROR RESET, and would you tell me when you're satisfied with the LGC self test?
- Ronald Evans (CAPCOM)
-
Columbia, Houston. Go ahead.
Expand selection up Contract selection down Close - Michael Collins (CMP)
-
Roger. Stars 25 and 42; angle difference 5 balls; NOUN 93, plus 00165, plus 00186, minus 00039, time of torquing 121 15. Over.
- Michael Collins (CMP)
-
This is Columbia saying the rendezvous radar transponder is operating.
Expand selection down Contract selection up - Ronald Evans (CAPCOM)
-
Tranquility Base, Houston. Request you go ahead and start the warmup on the rendezvous radar.
- Ronald Evans (CAPCOM)
-
Tranquility Base, Houston. Columbia will be overhead at 122 plus 22 plus 51. His LOS will be 29 35. Over.
- Neil Armstrong (CDR)
-
Houston, we'd like to check this on the tape meter against the AGS. We'll go back to altitude—altitude rates as soon as the rate starts to build up. Over.
- Neil Armstrong (CDR)
-
On second thought, since that will peg the range rate, I guess maybe we'd better not do that. And for this range that the AGS are showing now, 425 miles with a signal strength of 2.2. It looks like we ought to proceed on this. Over.
- Ronald Evans (CAPCOM)
-
Tranquility, affirmative, and we're saving it. We've got 4 so far, and it's looking good.
- Ronald Evans (CAPCOM)
-
Tranquility, Houston. Stand by on that now. We're getting the data now. We're checking on the VERB 83.
- Buzz Aldrin (LMP)
-
And we expect that we may lose lock when it passes overhead because of the MAX rate that the radar has.
- Ronald Evans (CAPCOM)
-
Roger. We had about 20 some points before you did that. And for your information, the reason the AGS is a little different there—The reason the AGS is a little different is because the K factor is a little bit wrong.
- Buzz Aldrin (LMP)
-
Has he already gone? Over. Okay. Okay. Has he already gone overhead, or do you want us to try and get in lock on again?
- Ronald Evans (CAPCOM)
-
Tranquility, affirmative. Try to lock on again, and you'll lose him at about 29 minutes and 35 seconds.
- Michael Collins (CMP)
-
I say I got five good marks. You got NOUN 49. When you get everything you need off the downlink, let me know.
- Michael Collins (CMP)
-
I'm staying in P22 here a second just to record the NOUN 89 and then over VERB 34.
- Ronald Evans (CAPCOM)
-
Roger. Request S BAND FUNCTION switch to RANGE. We're going to do some ranging on you. Also, I have an updated AGS K factor when you are ready to copy. Over.
