Kostas, you'll have to ground service the DG III prior to departure. There are two ways to
do it, depending if you are at KSC or some other Class "M" airport or if you are docked to
ISS, MIR or Brighton Beach.
After you load the scenario go to the Life Support Panel...
You're looking for the Input Pressure Valve, it should have two positions - Dock and Ext. If
you are at KSC, Dck will have a 000 pressure and EXT will have a pressure of 10.7 or
so. Set the A-B switch below the valve to off. Then press the switch below the input valve
that shows a positive pressure. When the switch turns green, move the A-B switch from
OFF to A. You should see the values on the O2, N2 gauges rise from 5%, 80% to 100%, 100%.
When that's done, move the A-B switch to the "B" position and you'll see the O2 and N2 on the
B side rise to 100%, 100%. After that's done, set the A-B switch to the OFF position, and
close the Input Pressure valve by pressing it (no light).
Now if you look at the Reserve Data Display, you'll see that the "A" system has about half
of your reserves and the "B" system has the other half. The remainder is the default load
for the DG III.
If you are docked to ISS, Mir or Brighton Beach, the only difference would be the need
to select the Dock input valve instead of the EXT valve. (I wouldn't recommend pulling a
year's worth of air from the ISS or Mir.) You can shut off the Input Pressure Valve, then
set the A-B switch to OFF. Once you undock from the station, set either the "A" or "B"
Cabin Air Recycling switches to OFF.
