most of the t ime during the 14 days.
We have recorded in
the flight book of the flight pla.n--those times th.at it went
off and on to the best of our lmowledge. I'm au.re we missed
several of them.
Borman
When we were sleeping particularly.
Lovell
When we were sleeping we missed them, but it appears to me
that there are two things now that these fuel cells have &
lot more latitude than we really first realized:
1) We can
oper&te with the fuel cells with delta Plights on more than
we thought we could.
.As a matter of fact , we were doing
normal purges with the .t'uel cell delta Plights on whioh the
systems book said flatly not to do. But we had some excel­
lent guidance a.nd assistance from the ground in keeping the
sections running.
Borman
I think so, too.
Lovell
I think that's what kept Stacks 2C and 2A going as l ong as
they did go.
The gauge is a little inaccurate to monitor
the system. If we are going to have troubles with fuel cells
as we did on this flight, and if the ground is going to keep
requesting accurate stack a.mp readouts.
The gauging system
is poor because it is ha.rd to read accurately the amps when
they are down in the low 1 and 2 amps.
Each indicator is
canted a different way-alternately throughout the 6 stack
