Chuck Wasson wrote a memo, dated June 27, 1969, to Gene Kranz and me defining in detail the Guidance and Control Division's (G&CD's) position on “in-flight gyro calibration and accelerometer bias update and redline values.” In it he pointed out that both the Mission Rules and the Mission Techniques Documents should be brought into agreement with his recommenda- tions. Actually this subject has been discussed endlessly in the Mission Techniques meetings and elsewhere and so there were no surprises in the values and techniques proposed. However, his memo does again draw our attention to the minor differences in official documentation and reminds us that that is a sloppy way to do business. I talked it over with Cliff Charlesworth (FCD) and Mal Johnston (MIT) and we all concurred that the numbers Chuck Wasson proposes are as good as any and we have taken steps to comply with his recommendation. Namely, future issues of Mission Rules and Mission Techniques Documents will conform with the G&CD's recommendations as listed in the referenced memo.
