CMP: Okay, I'm not sure what just happened. I just saw - down looking at the optics and all of a sudden I saw a warning light and I got a NO ATTITUDE and a GIMBAL LOCK light. And my - my ball seems to, in fact - it looks like the platform may be frozen. Although we're still - still in PTC here.
CC: Okay, we're seeing some telemetry. We saw something about the time you come on the line there.
CMP: Okay. And it shows the CDUs down there in NOUN 20 as being gimbal locked. nage 135
CC: Stana by a little bit, Ken. '..}e_retaking a look at 5he telemetry.
CC: Ken, just so we can make s_e we got it s_raight down here, could you run through again what you were doing, and then the secuence of even%s?
CMP: Okay, tlani<, l'm net real sure whe:_ this happened. I was trying %c see if i couldn't -oick up one of the planets in she optics, and I was using P52. And I had gone in and i was calling option 3 and then putting in p!ane_ vectors o_t of the Flight Plan and I tried - I t?ought I was going to catch, I guess it was Saturn And i% looked like i had jus-5 missed it. And il was driving around just kind of looking around _o see what i could see in the sky and waiting ts 3ry a_'_de!ek up Juriter. And somewhere in there,, i guess i came down to zero the optics or do something, and chon I looked down and saw i had a _GNCS l i_h%. And I guess i had Jus-- recently - I guess i was about ready to give up on it and call P001, and i think I had - in fact, I think I called POO at or just before the time I - we ,ended up with the SIMBAL LOCK and the NO ATTITUDE. Tha-3 was just a couple of seconds or so, ! guess, before I ,_alled you about it, maybe 15 seconds or So.
CC: Okay, You 6ct a GIP_AL LOCK - -
CMP: I can't, think of any ::ombination of DSKY innuts - I was trying to think if I cou!c have made some combination of DSKI' ink,uts that might of - Had I gotten in ahr_ost the right inputs that i could have caused the problem, bul I don't see where I was using any verbs or noLlns tha5 could have done this.
CC: 0kaM, you got a G!MBAL LOCK and N'.}ATT. Did you get an iSS warning?
CMP: No, sir; I did net.
CMP: And the NOb_ 20s were asproximavely correct for both pitch and roll_ _lthough the midale gimba! angle was completely ._ tc lunch.
CMP: Hoaston, C_sper.
CC: Go ahead_ ilen.
CMP: I'd like for you to thin_< about _he effects of having me !to ahead and do a VERi- L1 NOUN 20 to match up w_th the SCS. That thing's been drifting a good bit_ but, in any ease, m_.ybe I can get it close enou_h to have a starting point to try and pick up so_le things. I'd been looking in the - had been l:oking in the telescope just before this al! happened, and there's so much cf this - so many of thuse little particles cut there that chances of recognizing a star _avtern are extremely dubious, ii'd like to try. A_ad maybe we can work on somethi__g like the Earth_ maybe the Sun, or something ]£ke that.
MCC: Ge G&C.
CC: Okay, stana by.
MCC: Okay. Do y}u want to stand by on chis VERB 41 NOUN 20 until you get your GIi,_BALLOCK removed? Okay, CAP Ci,_,_,tell him we're working up - - Thank you.
CC: Casper, Houston. We'd like you to hold up on the VERB _1 NOU]'_20. We're working on a proced-_re to try to get _'id of the gimba! lock.
CMP: Okay. Did ?ou have any data coming down at the time this all happened, or were you in the blind?
CC: Roger. We tad good high bit ra_e data, and they're pouring over Chat now.
UNKNOWN: Okay. I'11 sit _ight then. Than_ you.
CC: Casper, Hou _on. ·
CMP: Go anead.
CC: Okay. We wsylv co try _o get the slatform inertial again, and _nat we'd like for you tc do is a VERB 23 NOU__ 20 ENTER, ENTER, VER_ 40 E_._ER.
CMP: VERB 23 NOUN 20 ENTER. Then you want me to put plus ENTER into that register. Okay, that got rid of the GIMBAL LOCK light. Now you'd like for me to do a VERB 417
CC: VERB 10 ENTER.
CMP: Okay. VERB h0 ENTER.
CC: Okay. Our data shows the platform's inertial now, Ken.
CMP: Roger. And it appears that way from here, too.
CC: Okay. Ken, you can go ahead now with you VERB 41 NOUN 20.
CMP: Okay. This will be a coarse align to the GDC angles, is that correct?
CC: Ken, hold up on that VERB 41 just a second.
CMP: Wilco. I'11 go ahead and load it but won't enter.
CC: Okay. Guidance has got a little thing they're looking at and talking to people in the back room, little discussion going on here.
CMP: Okay. I won't do a thing, then. Thank you.
CC: Casper, Houston. Are the GDC ball and the IMU ball completely out of sync?
CMP: Well, actually, they're not that far out. They're like 10 degrees in outer gimbal and let's see the - I guess the middle gimbal is off by about 2 degrees, the inner gimbal no more than 3, lots closer to 2 degrees.
CMP: - - that close. Tape °6/1 _a_e 139
CC: Casper, Houston.
LMP: Go aaead.
CC: Okay, I think we got the agreed-on procedure here - is to go ahead with the VERB 41 NOUN 20. That's procedure - in the G&C Checklist - 7-1. And reset the REFSMMAT - REFS_AT flag and press on through that. drifts,
CMP: Okay. I guess, based on our I'm not sure that's any better, but I guess that's no worse, so I'11 Just go to that one, then.
CC: Okay; 7-1.
CMP: Okay. That's page 7-1. I understand.
CMP: Hank, if it doesn't clear up, I won't be able to find any stars with no closer alignment than I have on this thing. Looks like I'm gonna have to get a - a coarser alignment by using some big ob- jects like Earth or something like that.
CC: Okay. Are those particles out there giving you a lot of trouble?
CMP: That's all there is. They're just everywhere.
CMP: When you combine them with the limited area that you have to look in because of the LM reflections, you find the telescope to be very unsatisfying.
CC: Casper, Houston. Why don't you go ahead and try then, with the - the Sun and the Moon? You've got a filter for the Sun_ right?
LMP: Th_'s affirmative.
CMP: Okay. I used the Earth and the Sun, and I got four balls 7, which I think is gonna be a signifi- cant impt'ovement. I'd like to go ahead and see what those torquing angles turn out Zo be.
CC: Roger. _e concur.
CMP: Okay. T%at looks about right for the amount that I had to correct for. It's - it's kind of hard to mark cn the Earth because you have to guess where the - where the - the terminator really ought to be.
CMP: ... torquing angles?
CC: Roger, Ken. Go ahead and torque.
CMP: Okay, Herlzy. If you have those angles, I'11 torque these.
CC: Ken, what was your NOUN 05?
CMP: Four balls 1.
CMP: Okay. I'11 torque these at on the minute, 11.
CC: Okay, clear to torque.
CMP: Okay. It looks like we're pretty much on target now, and L don't see any reason to torque these again - unless you particularly want to.
CC: Okay; we soncur, Ken. Don't torque those. And we want ts check a few switches. They're working on now getting a switch checklist, and then we're going to Let you get some rest and smoke the data over during the night and have it stored for you in the mo:_ning.
CMP: Okay. Can you give me any - Can you give me any cursory ideas of that, just the same - if there's any possibility I entered some%hing inadvertently? take Or does i5 too long to sort all that out?
CC: Okay. The preliminary look here - We think it's a hardware problems Ken. Some sort of a transient problem, and when we get the data in here, we'11 be able to tell a little more about it.
CMP: Okay. Guess I'm sorry to hear that.
CC: They - they don't think at this point that it's anything that you did, and it appears to be a transient problem, but we won't know until we take a look at it.
CMP: Okay. Let me give you one other little tidbit that now seems to be somewhat more of - of interest than it was before, and that's that when I take this OPTICS ZERO to ZERO, the area around the shaft peapack [?] makes a lot of - a lot more noise than the one in the trunnion. It seems to me that it's making more noise now than it used to. When I say used to, when we first started out - when we first started out, they were very, very quiet and you couldn't even hear them running. And now they're getting noisier. And that may be typical, but it's just one more thing that - I guess we'11 throw out all these things. I'11 try to minimize the number the times I ZERO the OPTICS, at least with the ZERO switch. I'11 use MANUAL wherever possible.
CC: Okay. That only occurs when you're zeroing?
CMP: That's affirmative. Well, actually, Hank, I just tried it in MA_AL. It occurs when - the noise occurs whenever I'm in an extremely high rate. You know, like using high in a max shaft rate.
CC: Okay, Ken. We'd like to check some switches up on panel 1.
CMP: Stand by a second.
CMP: Okay. Go ahead, Hank.
CC: Okay s we'd like to check position in FDAI SCALE.
CMP: The SCALE is in 5/1.
CC: Okay, SELECT.
CMP: SELECT is in 1/2, the SOURCE is in ATTITUDE SET, and the ATTITUDE SET is in GDC.
CC: Okay. That's what we wanted vo know. Thank you.
CMP: Okay, I think I'11 go ahead and get some sleep then. Got any notes from ... yet?
CC: Okay, stand by 1 sec.
CC: Okay, Ken. We don't have anything else ....
CC: Okay. You caught us on the antenna switch. We don't have anything else for you. We'11 look the data ore _, and try and get some word up to you to- morrow. It looks like to us now that you can get a full 8 hours sleep.
CMP: Okay. (Laughter) Thank you.
CC: See you vomorrow.
CMP: Okay, Hailk. How about - how about making the duller shift?

CDR: Houston, Apollo 16. Good morning.
CDR: Houston, how do you read Apollo 167 Over.
CC: 16_ you're loud and clear. How me?
CDR: I read you the same. Good morning to you.
CC: How are you doing this morning?
CDR: Doing great.
CDR: I guess that sort of depends on what y'all can saN about the old platform.
CC: Oks_, 16. The gimbal lock and the coarse align that you had back at 38 plus 18 was caused by a CDU transient in the yaw axis. The transient was in_ced when the TVC relay was disabled. And this relay is normally enabled when the OPTICS is in MANUAL and disabled when you select POO, and that's kind of the situation that you're in when that oc- curred. And Ken had just selected POO, and he had, prior to that, been using the OPTICS in MANUAL. And they say that this type transient has been observed in CSM 117 testing, and we're pres- ently looking at - a software workaround for LOI. And we'11 get some more words to you later on this - on this same subject.
CDR: Now you're talking. That's the best news I've hesrd today, so far.
CC: Oksy. And, John, we've had some problems here getting commands up to the bird - real-time com- mands. And we've got a command test we want to rom. And - we'11 be standing by. As soon as you can get ready, let us know and we'11 get into it.
CDR: Okay. We've got some seat flops to do and we'11 let you know.
CC: 16, in the situation we're in now, we've only got one omni that we can read, and we can't command. So we're cnly getting about 11 minutes of low-bit- rate data out of every 18 while you're in PTC. It's possible - we might lose you; if so, just stand by and we'11 pick you ap again.
LMP: Okay. We're ready for that co_.a:ad test, Pete.
CC: Okay, Charlie. We're gonna go one step at a time. First thing we want to do is bT TELEMETRY, CO_,_D RESET and then NORMAL.
LMP: Okay. I c'_n give you - You wan_ a CO_4AN2 RESET and then NDRMAL?
CC: Charlie, we want the UP TELE_ETRY C0_,_4A_D switch to RESET and then NORMAL.
LMP: Roger. It's RESET, NORMAL.
CC: Okay, Charlie. Stand by. We're gonna try some command.
CC: Okay, Charlie. That apparently didn't work. We'r_z going on i_. But we want to cycle the UP TELEM- ETRY switch OFF for 3 seconds and _hen back _o NORMAL.
LMP: Roger. in work.
LMP: Okay, you':_e back to NOP_MAL.
CC: Okay. We':_e trying commands no,,', Charlie. Stand by.
CC: Okay, Char!ie. That apparently cleared i_ ult.
CC: And, Charl e, we've got commands again. We'11 har_dle the antenna and the bit rate for you now. 30/3 Tape
CC: To repeat an old phrase, Charlie, we had a lot of people down here turning blue on this - until that - until that last little situation got cured there.
LMP: Was that that IMU problem?
CC: No, the - the - comm problem.
LMP: Well, you could put Feindell in the backup mode and just put him up on top of the building.
CC: We may have to put him up there anyway, Charlie.
LMP: (Laughter) Afraid so.
CC: 16, Houston. I've got about three - a couple, three updates to the Flight Plan. Whenever you're - it's convenient for you, we'11 read them _p. APOLLO 16 AIR-TO-GROUND VOICE TRANSCRIPTION

CC: Okay, Ken. We're all set.
CMP: Houston. Casper.
CC: Casper Houston. How do you read me?
CC: Casper Houston. How do you read?
CC: Casper Houston. Do you read?
CC: Casper we read you loud and clear. Do you read me?
CMP: Houston. Casper. Over.
CC: Casper we read you. Do you read us?
CMP: Houston. if you're reading Casper, we're transmit- ting in the blind. We have signal strength on the meter of about 60 percent. We're not receiving you and, based on your comment about the antennas, we'11 wait about 5 minutes and then try again be- fore we change the configuration.
CC: 16, you're loud and clear. Do you read Houston?
CMP: Roger. We lost you there for a while there, Don.

CMP: The backg,'ound tone at _he - t:ie background noise that the system is _k_ng righz now is a little different than it was making before, if that would help you figure out what the problem was. It's almost like it wasn't up-!i.mking, maybe.
CMP: Okay, Don; and, if you're ready, I'11 give you some status reports.
CC: Stand by just a minute, Ken.
CC: O_ay, Casper, go ahead with yo_ _ status report.

So I'11 starz with the commander's list and I'11 go through and I'11 skip the menus since they're on separate pages and come back to them. So let's start with A-i: 22035; Alfa 3: 7, good; Alfa 4: none; Alfa 5: 19, 15, 18; Alfa 6: 6, 5, 6, and 3. That's a total of four. Going to Bravc. Bravo 1: 15035; 6: good --that's on Bravo 3.

Okay, and if you want the menu stuff, I'11 go back to that now.
CMP: Okay. For John, and that's day 2, meal B, scratch the bread and peanut sutter. On meal C, scratch the frankfurters; add an orange drink.
CMP: Okay, on Bravo 2. Are you still there, Don?
CC: Affirmative; we're getting a lot of background noise. 16, hold off a minute - -
CMP: Okay, ... keep on going.
CC: - - we'11 switch omnis ... Hold off a minute, 16; we'11 switch omnis.
CC: Okay, Casper. Go ahead.
CMP: Okay, starting on - Where did you copy last?
CC: Okay, we got John, day 2, meal Charlie complete, and we're ready, I guess, for Bravo.
CMP: Okay, Bravo 2. On meal A, you can scratch sausage patties and - orange juice - and fruit cocktail.
CMP: On Bravo, that's meal B, you can scratch turkey and gravy, vanilla pudding, bread, peanut butter. Meal C, you can scratch the chocolate pudding.
CMP: Going to Charlie 2.
CMP: On meal A, scratch the sausage patties. Meal B, you can scratch the bread and peanut butter. Meal C, you can delete two of the frankfurters and scratch the chocolate pudding.
CC: Okay, Casper, we copied all that.
CMP: Okay, and a couple of other words here on the - We got ALFMED coming up; and, to date, Charlie saw some flashes the other night and not a whole heck of a lot of them last night. And I'm not sure I have seen any at all yet, and John may or may not. So, what we thought we'd do here is - We've got a our chores.

CMP: You know one of the things we need in this program is some o:_.topuses.
CMP: Okay, Don, I don't have the camera out, but how about Jus- reading to me whatever it is you want t_ say. I'11 write it down here.
CC: Okay. It's not - it's probably not worth writing down except maybe a little note to remind you the - the camera was observed to hang up in the BATTERY CHECK position full down, when you hit the camera light meter ON, CHECK. And what we want you to do is - the _ittle button on top of the camera there has a while band around the base of it - they wan_ to make sure that white line is visible on the light meter switch button. If it's not visible, you can take your fingernail and catch the top of that button and pull out on it until the white line is visible. And then, verify that the meter is operating by holding the camera up to a light and observing the meter response to varying light level.
CMP: Roger. We'11 make suave it works before we use it.

CMP: Always glad to help.
UNKNOWN: Okay, Pete, I'm up on biomed. How does it look?
CC: Okay, the biomed data looks good.
CDR: You can tell Charlie's still breathing, huh?
CC: It looks that way.
CDR: We've been suspecting it up here all along.
CDR: Houston, based on the burn yesterday, is the data you gave us for the SPS burn card still going to hold for LOI?
CDR: And the other question is, does it look like we're going to have another midcourse, and which one and how much is it?

CMP: Ge ahead, Houston, ... Say again on all ... on the burn card.
CC: Okay, 16, if you read. We probably will have to do some updating on that - on thaz pad. And we'11 lev you know on that and we'11 update it tomorrow. And on the miacourse 4 - midcourse 4 is looking pretty small, less than 1 foot per second now. If _t gets larger, we'11 probably go ahead and do it, but we'11 keep you advised on it.
CDR: Houston, yo,&r up-link keeps fading in and out on ycu.
CC: Rcger, 16, We're switching on ycu.
CDR: ... fading ...
CDR: Houston, i6. Do you read us new?
CC: ' I read you loud and clear. Do you read me?
CDR: And I read you same. You faded cuz on your last transmission again.
CC: Okay, hang on a minute until the comm clears up a little bit and then I'_i come back to you.
CC: Okay, 16. Let's try it again. On that updating the pad, we'11 get that to you tomorrow. And right now, midcou_se _ looks very small, less than 1 foot per second. If it gets larger, we will probably do it, but we'11 keep you advised on that.
CDR: Just to review that SPS pressure system - as near as I can make out, it's purely - we don't actually have a DELTA-P. It's Just - Of about more than 5 psi. What we do have is a gage difference. Is that not correct?
CC: _hat's affirmative, John. There's a - there's a chamber in there - a reference chamber that's supposed to be at atmospheric pressure. It has apparently vented to a vacuum condition, which krings in about - about a 14.7-psi bias. Then there's a 5-psi meter bias on top of that.
CDR: Ckay, so actually, the two meters, as we look at them now, are actually balanced. Is that not correct?
CC: I believe that's correct.
CC: John, the actual pressures on both meters - the actual pressures are the same, although the meters are reading differently.
CDR: Okay, we got the message.
LMP: Houston, 16. Will we need to charge battery B, just looking ahead in the Flight Plan a little bit?
CC: ()kay, Charlie, you can go ahead and start charging the battery now.
LMP: ()kay, Pete, BAT B _s on charge now.
CC: Understand. BAT B on charge.
LMP: Okay, Pete. We got you - FinalLy had time to lock out the window and you're Just coming into view again and just as pretty as ever.
CC: Very nice. What you looking at right now?
CC: Can you yell what part of the Earth?
LMP: We've go_ a half-Earth. Say again?
CC: Can you yell what part of the Earvh you're looking at?
LMP: Well, we got half-Earth, and we see a landmass - see the North Pole - the north polar cap with two big swirls coming out off of it to the southwest. i can see the subsolar point very distinctly. It's a bi_ white dot in the center towards the LM, away that's visible in the center. And - can't really make out exactly what it is. It's clear of clouds, though. It's the only place that's fairly clear.
CC: Okay_ we show you directly ober North Africa. And that's j_st about the terminator.
LMP: Okay_ yo_ got North Africa at the terminator?
CC: Just abo_t.
LMP: Okay, that's what it is, then, looking at it, yeah. It's - it's Africa. Looks like a good storm sys- tem up in the Atlantic Ocean and above the subsolar point.
LMP: The blue coloring - the white of the clouds and the blue of the ocean s Dick. Things just stayed pretty constant as we move out - still really a spectacular sight.
CDR: What do they think of this PTC down there in the trenches?
CC: It's looking real good.
CDR: It really does look good. Z don't know who to congratulate, Ken or the computer.
CC: I g_ess we'11 give Ken credit for that one.
CDR: Darn right.
CC: 16, let us kno what you think about the number TM of light flashes and whether or not it's feasible to try the ALFMED.

LMP: Pete, (ciea_'s throat) a little background on these flashes ...
CC: 16, Houston. We missed your comments on the light flashes. Yo?d started to give _hem to us, and you were blocked out by noise.
UNKNOWN: Roger, Pete. I was just telling you - the first night - during the firs% sleep period, whatever that was GE_, I saw numerous light flashes before going to sl_:ep, probably a - as freq - as high as three or four a minute. The next morning, they were not as numerous as that, and then last night still not as numerous. This morning, I was per- haps seeing maybe one every couple of minutes or so. If that frequency repeats itself during this test, is that good enough to go ahead?
CC: Okay, Charlie. If you see one every minute or so, that's enough to go ahead.
CC: And, 16. At 48:30 in the Flight Plan, there's a line that says "Synchronize mission timer to CMC clock," and it is not required.
UNKNOWN: Oh, that's great. Thank you. Hey, Don, is our comm gonna be good enough the way we're going here now for you to get the marks or are we gonna - shall we count on recording them on board too?
CC: You better record on board as well.
CMP: Okay. You'11 start the tape recorder, is that affirmative ?

CMP: MARK. ALF_D is off.
CC: 1_, Houston. Whenever you can copy, i've got some wcrds on the IMU problam that we had. Also some - aa entry to the G&C Checklist.
CMP: OLay, Don. How about standing by, would you? Stand by until we clean uv all the ._.
CMP: You're cutting out yretty bad, Don.
CC: 16, the PI advises cn the ALF?,_D experiment that we got about 70 counts, and he's very happy with the results, and he wants you to verify that the clutch is in the $TCW position.
CMP: _.at's a verify.
LMP: Okay, great. Those things - those things are really something, Don. There were a couple of the phenomena that I had seen previously that I didn't see today_ but there were some other ones today that were different too. The phenomena - the flashes leave no afterglow and they're - they're just instantaneous. Ail the colors are white - were all we saw. We saw no colors at all; neither John nor I. It was - every one we saw was white.
CC: Roger_ copy that.
UNKNOWN: Okay, Don. I'm ready to copy some things now.
CMP: Before we get into copying stuff, let me confirm what Charlie said about that clutch. Now i listened to that thing retract before_ and as soon as we went to the mid-position on the clutch - why, you can hear the plates come down. And we went ahead and rapped it once, anyhow, just to be sure, bu_ i didn't hear an_thing jiggle. And we cycled it vo OPERATE and then back to STOW, and i_ all feiV normal and the - the plate travel so_szaded proper.
CC: Okay, we cooied that, Ken.
CMP: Okay, and I guess my only comment on ALF_._EDis that I think those light flashes are made by the same guy that ma_es the emperor's clothes.
CC: That makes what?
CMP: I think theM're made by the same guy that makes the emperor's clothes.
CMP: Hey, Don, I'm standing by to copy -the words you got about P52s and G&N and any of those other subjects pertaining to our operation.
CC: Okay, Ken, i'11 - we'11 talk about the platform problem first, and I'm gonna back up and talk about the original data that we passed up because there are some small corrections to that. And then I'11 - I'11 try to break it down into about four shovelfuls here for you, because it's a fairly big mouthful if we try to do it all at once.
UNKNOWN: Okay. You have some stuff that I probably should copy, huh?
CC: Yes, I will have some items for you to copy.
CC: Hold off a minute, 16. We're coming up on an omni switch.
CC: Okay, 16. How do you read now?
CMP: Loud and c[_ear.
CC: Okay, we'l_ start here on this thing. First of all, the - the problem occ'ars, apparently, in CSM-117 when the TVC relay chan_es state, either going from enable to disable or from disable to enable. And it causes an electric: glitch that makes the CDUs go to 90 degrees; _n particular, the yaw CDU_ and therefore the CMC thinks it's in gimbal lock and goes into a coarse align mode. The - Some of the cases that could cause this, for example, are when you go to --when you select M_T_AL OPTICS, you have the TVC relay enabled and then if you go from MA_YgAL to ALTO, or if you hit the ZERO O_ICS switch with M_O_UAL OPTICS selected, or if you go from P52 to POO with the MANUAL OPTICS se- lected, you will reset the TVC relay, and that can cause the glitch. This is apparently what happened last night.
CMP: Okay, is it important for me to copy those things that cause this, or are you going to give me a way to prevent it?
CC: Negative. You don't have to copy those. That's just background. Now we're going to talk about what you can do here in P52s and maybe subsequently in - for the LOIs an_ for P40s. There are _wo ways to approach the P52. There's a - There's a quick- and-dirty way which is to simply go to SCS CONTROL, because with SCS control, the TVC relay is not enabled. And, by doing that, you don't run the risk of generating this glitch. That's not the way, however, that the guys are reco_uending, because they have a procedure that they think will handle not only the P52, but the burn cases. And they'd like you to get that procedure, and you're going to have to copy that cne.
CMP: Okay. How about running down that list of things that causes the TVC enable to change state again? Let me - let me copy those this time.
CC: Okay, will do. And - now - these cases are not all inclusive. These are just some examples that - that we can bring up to you. First of ail, the TVC relay is enabled when you select MA2_VJALOPTICS. It is then subsequen-ly disabled if you go from MA_AL to AUTO, or if'you go to zero the OPTICS with MANUAL selected, or if you go with M_qNUAL - with the MANUAL OPTICS selected, if you go from P52 to POO. But these are probably not the only cases; they're probably just some examples that we know of.
CC: Another important point, Ken, is that it changes state during the TVC gimbal drive check.
CMP: Yes, that's what I was afraid of. Okay.
CC: Okay. We're going to - This next _rocedure that I have to read up to you is probably going ye be the one that we'11 use to try to get around that. And also, we'd like you to use it in the P52s because it allows v s to monitor for the glitch, and at the same time _revents the glitch from bringing your platform down.
CC: Okay, if you're ready to copy - -
CC: - - I'11 read you up the procedures.
CMP: - - ... copy this or - Okay, I'11 just copy this on a scratch pad, and we'11 put it in the appropriate place, if that sounds reasonable.
CC: Roger. That sounds real good. Number 1, we want you to key VERB 48 ENTER and Icad NOUN 46, REGISTER 1. The first digit shculd be loa_ed as a 3. The rest of the numbers can be left as they are.
CMP: Okay, why don't you read on at abeut that pace, Don, and I'11 Just copy, and then I'11 read it back to you?
CC: Okay, the second step is key VEEB 25 NOUN 07 ENTER, 75 ENTER, - E_TER, 1 ENTER. That sets the average g flag, but does not turn average g on. The com- bination of those two will prevent the CMC from going into coarse align. After you've done that, se_-_ect you can P52 and use your normal align_ent procedures And, when you've ccmpleted the P52 tc terminate this - EMP, we'11 have you key VERB 48 ENTER, load NOUN h6 REGISTER 1 with its original value, whether that was 2 or 1 in the first digit. Step 2, we'11 have you a key VERB 25 NOUN 07 ENTER, 75 ENTER, _T ENTER, ENTER. That w_!l then return your - you to the correc_ DAP a__:dalso reset the average g flag.
CMP: Okay, that - that was, in VERB 25 NOUN 07, that was a 75 ENTER, 1 E_rER, and then zero ENTER or a 1 ENTER?
CC: Zero ENTER.
CC: Okay, that's the whole procedure.
CMP: Okay, let me look it over here for a second. At first glance, the first thing I see here looks like - do I - should I ...?
CC: 16, we're switching omnis; hold off a minute.
CC: Okay. We lost co_n vhere temporarily. You can go ahead now with the readback on that any time you're ready.
CMP: Okay. Did you Let KY questions about the VERB 46?
CC: Negative, but we have a caution note that says, "Do not key VERB h6 Et_ER while this EMP is in to prevent Sap - Saturn DAP actually coming on."
CMP: Okay, what you would do then is - we're gonna set Saturn DAP in average g in order to prevent coarse aligning in the event middle gimbal picks up spurious signals. And to do vhis, we set VERB 48 with a NOUN 46. Digit A is set to a 3, and we set the average g flag with a VERB 25 NOUN 07, address 75, bit t, set it to the 1. Then we should call P52 normally, and if the glitch occurs, it'11 be ignored. I assume from this if the glitch occurs s_ne time while we're in the process of taking marks, that we get some kind of garbage out of P52, b_ it should be obvious. And from what you gave me on this list up at the top, it looks like no:_mally we would not run across TVC ENABLE during that period. At the completion of a 52, we go back into a VERB 48, and now we take NOUN 46 back to its original values. Then we reset the average g flag by taking channel 75 bit 1 to a zero, using VERB 2_: NOUN 07, and the restrictions on this EM_ is shat we will not use VERB 46 at any sime while this is punched in,
CMP: Okay, do you have some words on how - on hJw we handle the Ph0?
CC: Okay, Ken, and - in the Ph0 is what we're thinking about and we haven't completely decided now is we probably use this F_MP before and after the TVC gimbal check, and we may move the TVC gimbal check earlier or before the burn so that we have plenty of time to get this thing in and out.
UNKNOWN: that sounds like a good plan.
CC: Okay, now i've got the last shove]ful here if you're ready to copy.
CMP: Okay, I've got my bucket out. alignment,
CC: Okay, if you should lose the platform we'11 do the same thing we tried last night, a VERB 23 NOUN 20 ENTER, ENTER, VERB 40 ENTER, and G/7-1, then go to the checklist, and do the ra_id IMU realig:_.
CMP: Okay, Don. If we tumble the thing again, we're going to release the platform by setting NOUN 20 to - to zeros, and we do that with the VERB 23 NOUN 20 ENTER, ENTER. Then we release the platform- with the VERB 40 ENTER, and then we go through page G/7-1 and get a rapid aligr_ment to the GDC. Now that - that assumes that what happened to us was the glitch in the middle gimba!. If I under- stood your conversation, it's possible to have a glitch in _ne of the other gimbals. Es that correct?
CC: That's correct. That will not, however, get you into the - into the problem that causes the plat- form to go into coarse align. And also, we were advised that while this EMP is in, you shouldn't have the problem with losing the platform alignment.
CMP: Okay. If we - if we get this glitch in one of the other axes - I - and we have the controls enabled, I assume one of the things we would - we'd see would be some unusual thruster activity.
CC: That's affirmative, and in that case I guess all you need - -
CMP: ... proper correction. Well, I'm trying to figure out what we'd do if we have a - say we're in attitude hold. If we have that glitch occur right now and - with our engines disabled, I don't think there would be any way I'd see it u_til I went to use some auto optics or something. And that - if we were in an attitude hold, it appears to me that I would see a - a DAP that appeared to be unstable in the axis that it was going for, or at least it would take off for so:me place other than where it is. And we would go to SCS momentarily, and the proper response would he a VERB 40, ENTER, and allow the CMC to zero and recount the IMU CDUs. Is that correct?
CMP: This TVC enable that we're talking about that's used for the gimbal drive test - now that's a fuaction only of the gimbal drive test and not a fuaction of the setting of the trims in P40. Is that correct?
CMP: Okay, so, our P40 then would be something like we would go out and we'11 get a gimbal drive check to you folks early, then we'11 turn the gimbals back off probably, and I'm just ... what I'm ... - -
CC: Omni switch coming up, 16. Stand by. Stand by, 16; we're switching omnis.
CC: 16, how dc you read now?
CMP: Loud and clear, Don.
CC: Okay. Go _head with your question.
CMP: I'm trying to give you my impression of what we're gonna be - the general approach to the burn - and we check out the gimbal drives and the gimbal trims and then, when we come into Ph0 for the actual burn, we would go ahead and use the SCS gimbal checks to verify all the gimbals are properly hooked up. Then we would bypass the flashing 202 with an ENTER, and we'd Just lec the gimbals go to trim, and everything else would be done nominaLy.
CC: Ken, I think your general impression is right. I guess we're not yet ready to commit ourselves to a - a set of procedures. We're going %o have Stu take a look at it in the simulator here, and we'11 come up to you later with some detailed procedures specifi- cally for the burn.
CMP: Roger. I understand that; I just wanted to make sure I had a general understanding in case we had to do some original thinking.
CC: Roger. I think we concur with whav you said so fa_'.
CMP: Okay. And the other thing, thav out of curiosity - if the guys in the back room, after they get throu_h getting all the important things squared away, tha_ they could kind of think some more about their list of things that causes this enable relay to change state. I'11 compile a list of vhose things in case we come across something later on that we hadn't thought about.
CC: Okay, Ken, we'11 do that for you. And there's one last note here, that, prior to yo,_r P52s, it'd he a good idea to align the GDC just prior Lc going i_ .
CMP: Yes, sir. I don't think I'11 let that guy get ver_ far away from us.
CC: Roger. 33/13 Tape
CC: And, Ken, I've got an update to the G&C Checklist on page 9-4 any time you're ready to copy.
CC: Okay, pencil in hand.
CC: Okay, on page 9-2, line 07, column A - -
CC: Column A, line 07, should read "76747." Line 11 should read "77552." Line 12, "77756"; line 13, "77307."
CMP: Okay, I 'm on page G/9-4, reading down column A. On line 7, I replace "77426" with "76747." On line 11, I replace "00214" with "77552." On line 12, I replace "77714" with 77756." Line 13, I replace "77446" with "77307."
CC: That's correct, Ken.
CC: And we've got, Ken, here some notes on this jet-on monitor EMP. We'd like to do a check on it at 54:25, and I can read you up the procedure for that any t_ne you're ready to copy.
CC: Okay, at 54:25 in the Flight Plan, we would like to add "P20 option 5," in the "LM checkout atti- tude'', NOUN 78, minus 09000, minus 03000, plus 25500; NOUN 79, plus 00050; NOUN 70, plus 00047. We will up link the jet-on monitor loads and, when the P20 maneuver is complete, you ca:_ do a VERB 74 ENTER. And the P20 attitude that we've selected will be the attitude that you're a_?eady in, so there is actually not a maneuver involved here.
CMP: Okay, when you say when maneuver complete, - does that mean that you would want us to maneuver to the LM checkout attitude using P20, or are you going to let us go to VERB 49 for that? And then, I'11 call it up and bypass the maneuver, is that correct?
CC: You can use a VERB 49 for that, Ken.
UNKNOWN: Okay, I understand. A VERB 49, and then we'11 call P20, and then you can command the same attitude I'm in.
CMP: In other w_rds, I've got the 50:18 the second time. Then you want the VERB 74, ENTER.
CC: That's affirmative. Coming up cn an omni switch, 16. Stand by.
CC: 16, how do you read now?
CC: Okay, the only other thing is at 56 hours, that's 56:00, we want you to terminate the jet-on monitor EMP.
CMP: Okay, can you tell me what dead band you are gonna be setting in there? it,'!i
