•
If you attach a non-empty bay tank, fuel from the bay tank will fill the main
tank.
•
Each bay tank's fuel/LOX load is preserved in the scenario file.
•
If you dump consumables from your ship with bay tanks attached, the
bay
tanks drain first.
•
If you resupply consumables with bay tanks attached, the ship’s
internal
tanks fill first and then any
bay
tanks.
Coolant Temperature Management
XR vessels’
internal electronics and computers are cooled via a liquid cooling system.
The coolant reserves are able to absorb a certain amount of heat, but this heat must
eventually be dissipated away from the ship via the radiator or a ground-based or
station-based external cooling system. If not, the internal computers and systems
will overheat and fail, causing the computers which regulate environmental systems
to fail as well. Once this occurs cabin oxygen will no longer be replenished and the
crew will lose consciousness or even die if cabin oxygen levels fall below about 10%.
To manage coolant temperature it is important to deploy the radiator as soon as
possible after reaching orbit. If you are landed or docked you may also enable the
external cooling system, which works by connecting an external coolant line from a
ground- or station-based cooling system. External cooling is somewhat more
efficient than the radiator, and if you are landed or docked you may also enable
both
systems simultaneously to cool the ship at more than twice the rate of the radiator
alone. External cooling is activated via a switch on the lower panel.
