Attached is an MIT memo I thought you should see. It proposes that the MCC update the gyro compensation terms in the spacecraft computers whenever they are detectably wrong. One benefit, of course, is the possibility of eliminating a bunch of IMU alignments. But more important, it keeps the system right….

A lot of work is going into the subject contingency – with respect to:…
GDC required for TLI
In reference to your November 18 memo to me in which you state that the Gyro Display Coupler (GDC) is required to be operable for commitment to TLI, I would like to assure you that current C’ mission rules reflect this requirement. It is agreed by everyone I have talked to that redundant attitude reference…
Lunar orbit revolution counter for C’
This may seem like a trivial matter – however, before any confusion arises let’s firmly establish the means of identifying revolutions in lunar orbit by number. Specifically, unless there’s some good reason for choosing another way:…
C’ Lunar Orbit – Navigation and Block Data
On Thursday, November 7, we gathered with the C’ Flight Crew and everyone else who was interested in the lunar orbit Operations On that flight. At this meeting we cleaned up a lot of loose ends primarily dealing with the lunar orbit navigation and with block data. This memo is to report the new things…
C’ Mission Techniques
Attached are a list of ground rules and working agreements I compiled from my notes taken at the September 13 and 14 Mission Techniques meetings and the September 20 Lunar Abort meeting, all on the C’ mission. This list is far from complete. Basically, these items are only the changes and additions to the material…
C’ Contingency Review
We went through the draft of the C’ Contingency Mission Techniques document on October 22, and I must say I was impressed with its quality. It seemed to me the Flight Analysis Branch, the Apollo Abort Working Group, and TRW had done a good job of putting this together. The final version will be distributed…
Review of the Mission Techniques for Saturn V/Apollo Launch Phase Aborts
This memo is to backup our phone call notifying you of the review of the Saturn V/Apollo Launch Phase Abort Mission Techniques Document to be held Thursday, October 3, 1968, at 1:00 p.m. in Building 4, Room 383. At that meeting we will thoroughly discuss the attached draft of that document, as it applies to…
Recommendation to retain the Two-Stage Lunar Orbit Insertion (LOI) Maneuver
This memorandum documents the results of our review of the two-stage LOI maneuver which you requested as a result of a recent OMSF suggestion that it might be preferable to return to a single burn plan. Participation in this review involved all operational elements of MSC concerned in this matter. The conclusions are unanimous….
