Spacelog Apollo 13

Fred, one—one point on the PTC requests that, about an hour or less from now when you make your 90-degree change, that you do it in PGNS AUTO as opposed to ATT HOLD. Reason is that if you're in ATT HOLD, it establishes a new null point each time you stop the—the maneuver. Over.

Okay. You want us to make the maneuver with PGNS AUTO rather than the PGNS ATT HOLD. Is that right?

Yes. That's correct.

And, Fred, advise that it—it is a manual maneuver.

13, Houston. You'd be using X-axis override. It will be a manual maneuver, but with the PGNS AUTO mode.

Okay.

And if you're ready to copy, Charlie is going to be on in a minute with some recommended checklist changes for your upcoming burn. Over.

Okay. Stand by 1.

I'm going to erase this.

Hello, Aquarius; Houston. Do you read? Over.

Yes. Stand by 1 …

Okay. Which book are you going to give me some words in, Charlie?

Houston, Aquarius. Which book do you want us to have out? contingency …?

Houston. This is Houston, Aquarius. Say again. Over.

Houston, Aquarius. Which book do you want me to update here, Charlie, the contingency QR DPS?

Okay, Fred-o, we'd like you to get out the contingency checklist; turn to page 1, the 2-hour activation. Over.

Okay. I'm right there.

Okay. On page 1, the only thing we have to do is EPS Activation, step 2, CB(16) EPS: DISPLAY, CLOSE. Over.

Okay. On page 1, we need EPS DISPLAY, CLOSE, under EPS Activation, step 2.

Okay. Turning over to page 2, we'd like you to complete step 5 and step 6 with the following changes. POWER/TEMP MONITOR, AC BUS, INVERTER 2, then INVERTER 1. Fourth line CB(11), EPS: INVERTER 2, OPEN. Over.

Okay, on step number—or page 2, we should do step 5 and modify step 6 second line to read INVERTER 2, then INVERTER 1, to the last line of step 6 CB(11), EPS INVERTER 2, OPEN.

Okay. That will be on CB(16), Fred-o, but it's INVERTER 2 OPEN. Okay, on the Mission Timer Activation. Do step 1, correction, lines 1 and 2. Omit “set mission timer on CSM mark” and insert a VERB 16, NOUN 65, set mission timer. Over.

Okay, Fred-o, good show. On row 4, starting with ECS: SUIT FAN 1, CLOSE; GLYCOL PUMP AUTO TRANSFER, CLOSE. Under COMM: VHF B TRANSMITTER, OPEN; VHF A RECEIVER, OPEN. Under PGNS: SIGNAL STRENGTH DISPLAY, OPEN; IMU OPERATE, CLOSE. Under EPS, row 5: CROSS TIE BUS, OPEN; and INVERTER 1, CLOSE. Over.

Okay, stand by just 1.

Okay, panel 11 configuration, top row: AC BUS B, I want the S-BAND ANTENNA, OPEN, ORDEAL, OPEN; AC BUS A, TAPE RECORDER, OPEN. Second row, under RCS SYSTEM A, I want MAIN SOV through QUAD 1 TCA, all CLOSED. COMMANDER'S X-POINTER under FLIGHT DISPLAYS, OPEN; COAS, OPEN; ORDEAL, OPEN. Third row: RENDEZVOUS RADAR STANDBY HEATER, OPEN; LANDING RADAR HEATER, OPEN. Under STAB/CONTROL: ATTITUDE DIRECT breaker, CLOSED; ED: LOGIC POWER A, OPEN; LIGHTING: UTILITY, OPEN. Under ECS: SUIT FAN 1, CLOSED; AUTO TRANSFER, CLOSED. Under COMM: VHF B TRANSMITTER, OPEN; VHF A RECEIVER, OPEN. Under PGNS: SIGNAL STRENGTH DISPLAY, OPEN; IMU OPERATE, CLOSED. Bottom row, EPS: CROSS TIE BUS, OPEN; INVERTER 1, CLOSED.

Roger, Fred. Good readback. Starting with panel 16. Under FLIGHT DISPLAYS, row 1: SE CROSS-POINTERS, OPEN; RCS SYSTEM Bravo—QUAD 1 TCA's, CLOSE; QUAD 2, CLOSE; QUAD 3, CLOSE; QUAD 4, CLOSE. Second row, under LIGHTING: FLOOD is your choice. You can either use them or not. Under ED: LOGIC POWER Bravo, OPEN; ECS: SUIT FLOW CONTROL, OPEN. Third row, under COMM: DISPLAY, OPEN; VHF A TRANSMITTER, OPEN; VHF B RECEIVER, OPEN; S-BAND ANTENNA, OPEN. Fourth row, under HEATERS: DISPLAY, OPEN; under EPS: INVERTER 2, OPEN. And that's it. Readback. Over.

Okay, panel 16, top row, FLIGHT DISPLAYS: SYSTEM ENGINEER CROSS-POINTER, OPEN; RCS SYSTEM B: QUADs 1 through 4 TCAs, all CLOSED. Second row, LIGHTING: FLOODS we'll probably have open—our choice. ED: LOGIC POWER B, OPEN; ECS: SUIT FLOW CONTROL, OPEN. Under COMM: DISPLAY, OPEN; VHF A TRANSMITTER, OPEN; VHF B RECEIVER, OPEN; S-BAND ANTENNA, OPEN. Bottom row, HEATERS: DISPLAY, OPEN. Under EPS: INVERTER 2, OPEN.

Roger. Good readback. Okay, continuing on. Nothing on page 6; nothing on page 7. Nothing on page 8 or 9. Nothing on page 10 or 11. On page 12, we want the—to perform —

Hold it. Hold on just a minute, Charlie.

Okay.

Okay. Go ahead, page 12. I'm there.

Okay Fred-o. On page 12, we want the MSFN updates. We've got some vectors for you and a P30 pad. And we'll—when you get to that state, we'll let you know when we want to uplink. Okay. Under “AGS Activation and Self Test,” perform the entire procedure. On page 13, under “AGS Aline,” do step 1; under “DAP Set, Gimbal/Throttle Test,” do step 1 with the following change. Under “THROTTLE CONTROL,” we want it “AUTO.” Over.

Okay. I'll catch up here. On page 12, you'll give us MSFN updates, some vectors, and a P30; and we're to do the entire “AGS Activation and Self Test.” On page 13, we'll do the “AGS Align” and under “DAP Set, Gimbal/Throttle Test,” step 1, I've changed “THROTTLE CONTROL MANUAL” to “THROTTLE CONTROL AUTO.”

Good readback. Turning over to page 14, step 2, we want you to change the DAP NOUN 46 to 31021. Then after the NOUN 47, insert “VERB 34, ENTER.” Over.

Okay. On page 14, a VERB 48, DAP load, NOUN 46 changed to 31021. I assume you will give us any updated weights if we need any, and after the NOUN 47, a “VERB 34, ENTER.” So, I—you're saying our gimbals look all right.

That's affirmative on the gimbals, Fred. Nothing else on page 14. Proceed to page 15, and under “RCS CHECKOUT,” we'd like to scratch that wording and just say “Verify the following switches: GUIDANCE CONTROL, PGNS;” step 3—correction—it's line 3, change “ATTITUDE CONTROL (3)” to “MODE CONTROL;” “MODE CONTROL (BOTH)” to “AUTO.” Verify ACA PROP, LMP ENABLE; ACA/4 JET, LMP ENABLE; TTCA/TRANSLATION, LMP, ENABLE. That is all on page 15. Over.

Okay. On page 15, we'll change the heading “RCS CHECKOUT” to “Verify following switches,” and those switches are “GUIDANCE CONTROL, PGNS;” third line, “ATTITUDE CONTROL (3)” to “MODE CONTROL” now; and then “MODE CONTROL (BOTH)” to “AUTO” and ACA PROP, LMP ENABLE; ACA/4 JET, LMP ENABLE; and TTCA/TRANSLATION, LMP ENABLE.
