FC/Chief, Flight Control Division10 MAR 196767-FM1-21FM/Chief, Mission Planning and Analysis DivisionService Module RCS propellant remaining calculations in the CMC
In response to your memo dated January 13, same subject as above, we requested the Guidance and Control Division to carry out a study into the possibility of adding a CMC routine to complete RCS propellant consumed. The results of this study are detailed in the attached memo. As you can see, they have concluded that not only would such a computa- tion be quite inaccurate but, “…the amount of data which would have to be handled is felt to be prohibitive”. It is their recommendation that such a program not be considered for use in the CMC. On the other hand, if you still feel there is merit in this proposal, I suggest your people contant Guidance and Control Division personnel directly.
