1 - 18 5. CSM/LM and CSM attitude maneuvers will normally be at a rate of O.2°/sec or O.5°/sec. Unless other rates are required. NOTE: At 0.2°/sec, 15 minutes is required to maneuver 180°. At 0.5°/sec, 6 minutes is required to maneuver 180°. 6. Passive thermal control mode will be initiated after MCC1 or as soon as MCC1 is scrubbed and maintained throughout the mission (except in lunar orbit) until at least three hours before entry except for interruptions for midcourse corrections, communications orientation (maximum interruption of three hours). PTC will not be initiated before approximately 7:00 GET. 7. Service Propulsion System A11 SPS burns will be initiated on Bank A except LOI1 which will be initiated on Bank B. F. LM Notes 1. Entries into the LM a. Three entries into the LM are scheduled in the timeline at 56:30, 81:30 and 95:52 GET respectively. b. The first entry (56:30 GET) will be for LM familiarization and will be performed by the CDR and LMP in the constant wear garments. During this period there will be approximately 5 minutes of VHF-B LBR data which will be recorded by the DSE in the CSM. The LM will remain on CSM power during the crew familiarization period. c. The second entry (81:30 GET) will be for LM housekeeping and will be performed by the LMP in constant wear garments. During this period the LM will go to internal power for the S-Band/VHF B voice activation. d. The third entry into the LM (95:52 GET) will be performed by the LMP in LCG‘s to prepare the LM for undocking and descent to the lunar surface. During this period the LMP and CDR initially transfer to the LM in LCG‘s then return to the CSM for PGA donning. 2. Environmental Control System and Cabin Pressurization a. The LM cabin will contain ambient air at lift off and will bleed down to zero pressure psi during the launch. b. The LM will be pressurized for transposition and docking after which it will be isolated and the pressure periodically monitored. c. The LM will be pressurized prior to the first entry (LM familiarization) after which it will be isolated again for the remainder of the TLC period. d. Prior to the second entry (LM housekeeping) it will be pressurized again and will remain pressurized. 3. Guidance and Navigation a. Two LGC erasable memory dumps and MCC-H verifications will be accomplished prior to DOI. If a significant number of errors are found, memory correction and re-verification will be performed before DOI. b. The LM IMU will be manually aligned to the CSM IMU during the DOI Day LM activation and checkout. P52/AOT alignments will be performed as close to DOI as possible. c. All translations during the undocked manned LM operations will be under PGNCS control. d. The capability for MCC-H to update the LGC via uplink will normally be blocked by the LMP UP-DATA LINK switch (panel 12). 4. RCS Operation and Interface Constraints a. During CSM/LM docked checkout operations, the LM steerable and/or RR antennas will not be powered down once they have been activated. The SM B3 and C4 thrusters will be deactivated before the LM steerable and/or RR antennas have been unstowed in order to prevent SM-RCS impingement on these antennas.
