Orbiter 2024 Install Checklist

Because I keep messing up my install and need reminders...

Main Installation

  1. Install Orbiter 2024 (2.67 GB, Forum, Direct)
If you have like 100 GB to spare, you can also download the high-resolution textures: Orbiter. Torrent them if you can. Alternatively, if you want to save 86 MB, you can delete XRSound\Default\Altea STS.

Mod Installation

Essential

  1. Download Altea Aerospace Mods (68.5 MB total, Altea):
  2. Download Dan's Mods (Currently only DGIV works in 2024): The Arrow Freighter doesn't 100% work yet but if you want to try it: (360 MB, excl. XR2, Method Source):
    1. UCGO 3.0 + UMmu 3.0 - 2014 (192 MB, Dan, Direct)
    2. OrbiterSound 5.0 (96.2 MB, Dan, Direct)
    3. GeneralVehicle (6.70 MB Forum)

    5. XR2 (See above)
    6. Arrow Freighter 2016 (63.5 MB, Direct, overwrite???)
    7. Arrow Freighter 2016 Patch (367 kB, Direct, overwrite)
    Afterwards, enable both XRSound and OrbiterSound.
  3. Download essential MFDs (14.8 MB total)

Might be cool...?

Fuel flow seems to remain proportional between turbo and normal modes. This means for an extra 23.08% thrust, you burn 42.47% more fuel, making it about 15.75% less efficient. Not sure what the fuel flow function is. It can be roughly approximated with -2.32386e-6 * p + 5.88154 where p is the static pressure.
