How do I keep from running out of APU fuel?

[Pilot7893]

I'm just starting to use the XR5, but my missions always end horrible because I run out of APU fuel in orbit. And that's just deploying a sattelite. How do I conserve it for days while reundevousing?

Does turrning APUs off help?

You can change the rate at which APU fuel is consumed in your Config\XR5VaguardPrefs.cfg file:

#--------------------------------------------------------------------------
# APU Fuel Burn Rate : this is the rate at which APU fuel is burned in kg/sec.
# The Auxiliary Power Unit (APU) provides hydraulic power to the ship.
# 0 = unlimited : (runs indefinitely)
# 1 = very low : 20.1 kg/minute (44 lb/minute) (3.7 hours runtime)
# 2 = low : 40.3 kg/minute (89 lb/minute) (110 minutes runtime)
# 3 = moderate : 60.4 kg/minute (133 lb/minute) (74 minutes runtime)
# 4 = realistic : 90.6 kg/minute (200 lb/minute) (49 minutes runtime)
# 5 = expert : 135.9 kg/minute (300 lb/minute) (33 minutes runtime)
#
# The default value is 2 (low: 110 minutes runtime).
#--------------------------------------------------------------------------
APUFuelBurnRate=2

It's more fun to conserve fuel by turning off the APU when you don't need it (just click the bright red APU button or press CTRL-A), but if you'd rather increase the runtime, just set APUFuelBurnRate=1 or APUFuelBurnRate=0 in your preference file.

For more information, refer to the section titled APU Fuel Management on page 35 of the XR5 Vanguard Flight Operations Manual.

Won't the crew suffocate?

No! The APUs are only used to generate hydraulic pressure. It isn't an ECLSS.

Unless you need to operate the gear, aerodynamic surfaces or open/close cargo hatch or radiators, switch it off. That way you'll have enough.

Cargo bay doors and radiators are not hydraulic. They use electric motors.

In the Space Shuttle, but not in the DeltaGlider XR series. There they are hydraulic.

Oh, I'm sorry !! That's what I get, reading from the end of a thread.:sorry:
