]See Table 3.4-17 for actual propellant load calculation.
2See Section 5.6 for explanation of trapped propellants.
3See Table 3.4-18 for loading uncertainties.
4PV ullage calculation should be 125_+50 cubic inches for LM/RCS fuel and
23R.5±50 cubic inches for LM/RCS oxidizer per tank.
5LM/RCS required load includes propellant required to fill RCS manifolds
to isolation valves. See Table 3.4-16. See Section 5.6 for trapped
propellants.
6The indicated items should be loaded in accordance with loading windows
contained in the CSM/LM Spacecraft Operational Data Book, Volume II,
Part 2, SNA-8-D-O27PT2.
7LM-8 Descent Water shall be loaded to provide 250-0.0+i0.0 pounds
at Earth Launch. Initial load will be determined by sampling requirements.
