1 - 14 9. All onboard gage readings will be read directly from the gages. and will not be corrected by the appropriate calibration factors. B. Photography Photographic requirements were derived from the following: a. Lunar Surface Operations Plan b. Photographic Operations Plan C. Procedures l. CSM Crew procedures called out in the flight plan may be found in the following documents: a. Apollo Operations Handbook - CSM-107 (AOH), Volume 1/2 b. Crew Checklist c. CSM Rendezvous Procedure d. Abort Summary Document e. Apollo Entry Summary Document f. Photographic Operations Plan g. Descent Procedures Document h. Ascent Procedures Document i. Lunar Landmark Tracking Attitude Studies j. Lunar Orbit Attitude Sequence for Mission G k. Data Priority Documents 2. LM Crew procedures called out in the flight plan may be found in the following documents: a. Apollo Operations Handbook LM-5 Volume 1/2 b. Crew Checklist c. LM Rendezvous Procedures d. LM Descent/Ascent Summary Document e. Lunar Landing Phase Photographic Operations Plan f. Data Priority Documents g. EVA Procedures h. Apollo Lunar Surface Operations Plan D. Communications 1. General a. CSM and LM HBR data transmissions in lunar orbit will normal- ly require the use of the high gain or steerable antennas b. During communications, the spacecraft will be referred to by name (Apollo 11) and MCC-H will be referred to as Houston. c. The preferred S-Band communications are: (1) CSM (a) Uplink Mode 6 (Voice, PRN, and Updata) (b) Downlink Mode 2 (Voice, PRN, TLM-HBR) (2) LM (a) Uplink Mode 7 (Voice, Updata) (b) Downlink Mode 1 (Voice, TLM-HBR) d. LM voice recorder has a maximum utilization of 10 hours. This recorder will be used during LM operations to record all LM voice data during undocked operations (27 hours 42 minutes). This recorder will be operated in the VOX mode. e. A small portable voice recorder will be carried in the CM to be used at the discretion of the crew as a voice recorder back- up. This recorder will not be transferred to the LM for use during undocked operations. f. The S-band“squelch“ will be on during the sleep periods in or- der to prevent MSFN fade-out noise from disturbing the crew.
