Spacelog Apollo 13

13, Houston. We see you now in the AUTO maneuver. How are your error needles looking now?

Okay. They look like they are working their way in, Vance.

Okay. You think maybe they are working right now?

Yes. Because we got a 270-degree roll, our pitch and yaw needles are reversed.

Okay.

Say, how do you read, Vance? …

Fred, you are starting to fade out. Request AFT OMNI, OMNI AFT.

Okay. You've got AFT OMNI.

Thank you.

13, Houston.

Okay, Houston; Aquarius. We appear to be there—at the burn attitude. And now do you want us to change the DAP?

Roger, Jim. We have a procedure to give you for widening the deadband to 5 degrees for the PTC in the next 3 or 4 hours, if you're ready to copy.

Okay, stand by.

Go ahead.

Okay. VERB 21, NOUN 01, ENTER; 3011, ENTER; 44, ENTER. Now, that's the procedure for widening the deadband to 5 degrees with the DAP. Later on, prior to the burn, you would return the deadband to 1.4 degrees, and if you're ready to copy, I'll read you that.

Stand by.

Okay.

Go ahead.

Okay. To return the deadband later to 1.4 degrees: VERB 21, NOUN 01, ENTER; 3011, ENTER; 200, ENTER. Over.

Okay, Vance. To widen the deadband, we'll enter a VERB 21, NOUN 01, ENTER; 3011, ENTER; 44, ENTER. Before the burn to go back to narrow deadband, it's VERB 21, NOUN 01, ENTER; 3011, ENTER; 200, ENTER.

Roger, Readback correct.

And, Houston, I'll guess we'll do this PTC in yaw, and do you want them all powered down?

Stand by.

Okay, Apollo 13. Over.

Go ahead.

Okay, that's affirm. You'll be doing the PTC in yaw, and we'll give you a call at each time you change yaw—yaw attitude. Aside from that, request low bit rate off; then DOWN VOICE BACKUP OFF; then POWER AMPL OFF; and then FDAI OFF.

Okay, Vance. On the power down, we go low bit rate; DOWN VOICE BACKUP, we'll pull the POWER AMPL breaker; and we'll power down the FDAI and the AC.

That's affirm. And the AOT, too.

Okay, are you all set for old a -

Okay, Houston; Aquarius. How do you read DOWN VOICE BACKUP?

Reading you loud—loud and clear now, Fred.

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. We'll do the Mission Timer Activation except we'll set it on VERB 16, NOUN 65.

Okay. Proceeding on to step, correction, page 3, CWEA checkout. Step 1, perform step 1. Warning lights will be ASCENT PRESS, CES AC, and CES DC. Under the caution lights, we may have a heater light. And that's all. Okay, perform—under the circuit breaker 16 —

I can't understand you. I'll switch OMNIs.

Say again. Over.

I'm going to switch to OMNIs here, Charlie, you're starting to fade out.

Understand. Switching OMNIs. Over.

Okay. How do you read? …, how do you read me now?

Okay, you're a little better. How me? Over.

Okay, Houston. Coming in loud and clear. I got your caution/warning checkout, step 1, do; the warning lights we'll have will be ASCENT PRESS, CES AC, CES DC. The only caution lights we may have will be a heater light and go ahead and proceed from there.

Okay, good. The component light, we won't have the H₂O SEP. Okay, on CB(16) right under that, “HEATER DISPLAY, CLOSE,” you can scratch that out. Perform all of step 2 and perform step 4 with the following changes. On panel 11, under AC BUS B, are you ready to copy? Over.

Go ahead.

Okay, under AC BUS B: S-BAND ANTENNA, OPEN; ORDEAL, OPEN. Under AC BUS A: TAPE RECORDER, OPEN. Row 2 under RCS SYSTEM A: MAIN SOV. Starting with a QUAD TCA; all four CLOSED. Under FLIGHT DISPLAYS: CROSS—COMMANDER CROSS-POINTER, OPEN; COAS, OPEN; ORDEAL, OPEN. For row 3 under HEATERS: RENDEZVOUS RADAR STANDBY, OPEN; LANDING RADAR, OPEN. Under STAB/CONTROL: ATTITUDE DIRECT CONTROL, CLOSE. Under ED: LOGIC POWER A, OPEN; and under LIGHTING: UTILITY, OPEN. Are you with me? Over.

Yes. I'm still with you, Charlie; go ahead.

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.
