maybe this might associate itself in some wa;y
with something in the system prior.
I think it was prior, because we were in Reentry
Rate Command and we started the roll. Then the
yaw needle drifted on out and it looked to me
like it never got over about 3 degrees/second.
I was trying to read the 0.1 degree/second seal~
It might have gone on to 4 degrees/second with
the roll rate we had in there , and the jets just
kept right on firing constantly.
What I had done when we started was to leave the
roll gyro on, and I rolled the thing over till
I got almost full deflection on the needle .
Then
I put the roll gyro off so I'd have 15 degrees
and we wouldn't tend to overrate the thing so
t hat the Reentry Rate Command was firing all
the time .
What I think happened was that as
we went on down, the yaw rate needle tended to
drift on out .
I don't know if you noticed it or
not , but it tended to drift out . It started at
around 2 degrees/second, and it drifted on out
slowly until it got to about 4 degrees.
I
thought it never got out to more than 3 degrees/
second .
Later on, when we started oscillating
