Reference: Memorandum from CA/Director for Flight Crew Operations to FM/Howard W. Tindall, Jr., “AGS Software Documentation”, dated January 18, 1967.

The current status of Abort Guidance System (AGS) software documen- tation is given here in reply to the referenced memorandum concern- ing the same subject.

The LM AGS Software Development and Verification Plan, dated May 25, 1966, is currently being revised. Among other things, the content of the Operation Procedures Document contained in Design Report #3 for each mission will be redefined and the procedure by which MSC reviews and officially approves LM AGS Design Reports will be changed.

The Operating Procedures Document was not originally intended to be an all-inclusive document to be used by the flight crew for operational planning. However, since it could be used for that purpose if written with that objective in mind, we will take steps to incorporate your recommendations.

The Operating Procedures Document and Design Report #3 for the AS-258 mission will be released in a few days. This document will not contain the changes discussed by Cmdr. Mitchell with MPAD and TRW personnel on January 19, 1967. However, these changes and those listed in the refer- enced memorandum will be incorporated into the AS-503 Operating Proce- dures Document. Preliminary copies of this document will be available for your review by February 15, 1967. The final AS-503 document will be available by about March 1. It is expected that the AS-258 and AS-503 AGS program and procedures will not be different. Therefore, the final AS-503 documents may be used in your work in preparation for both the AS-258 and AS-503 flights. If this is not the case, differences will be clearly pointed out in the AS-503 documentation.
