1. Since I was surprised at what Gunter Sabionski told me and, in turn, almost everyone I have told has been surprised, perhaps you too will be surprised to learn that the least significant increment output by the CSM accelerometer is equivalent to 0.2 fps! (The LM is considerably better, the value being 0.03 fps per bit.) I suppose we have all heard these numbers before in units of centimeters per second which made them sound much smaller than they really are and I, for one, never bothered to make the conversion. Of course, what this means is that it will be impossible to trim delta V residuals in the command module dependably to less than 0.2 fps. Also, the actual trimming operation will be a little more difficult since the readout will jump in such big steps.
2. No big deal, just thought you might be interested.
