See list belowJAN 15 196868-FM-T-7FM/Deputy ChiefCrew familiarization and training for TLI
1. During our many discussions on the need for command module steering of the S-IVB during TLI, a potential crew familiarization. training problem became apparent. Specifically, even if the P-15 CSM TLI Steering is retained, it is not obvious that it will be possible to make the AMS faithfully reproduce the attitude excursions which may be encountered due to such things as propellant slosh, structural bending and, particularly, propellant utilization system oscillations. For example, the AS-501 mission oscillations around the expected attitude apparently are in excess of 10° with some rather high attitude rates.
2. I checked with Jim Miller with regard to fidelity of the modeling in the GESC and he informed me that all of these characteristics have been included in their program, and it would be no problem for them to supply open loop trajectory tapes to the AMS and closed loop simulations when the AMS is tied into the MCC. I just wanted to make sure that all of you were aware this capability probably exists today. Jim told me he intends to run some AS-501 cases and compare the results with our actual experience to verify his system is right.
