A32NX Cannot use is as it doesn't appear in the Aircraft Section menu

First of all, let’s do a little housekeeping on your settings:

  1. Set your flight model to Modern, not legacy.
  2. Set your assist settings to True to Life/Hard. Turning on Taxi Ribbon is still acceptable.
  3. In your Graphic settings, turn the AI Traffic to use Generic Model. Set this to ON. (And maybe multiplayer generic model set to ON as well just in case).

Then, try spawning at the gate to follow this simplified checklist. Make sure you have fuel on board too. By default you should have fuel ready at 50% capacity.:

On the overhead panel:

  1. Switch Battery 1 and 2 ON.
  2. Switch External Power ON.
  3. Align IR 1, 3, and 2 to NAV. (might take between 1 - 10 minutes for it to finish aligning depending on your mod settings)
  4. Switch Fuel pumps, 1, 2 for left, 1, 2, for center, and 1, 2 for right fuel tanks.
  5. APU master switch ON. Wait 3 seconds.
  6. APU Starter switch ON. Wait for 1-2 minutes to get the APU running.
  7. APU will be ready when the APU start switch change from blue ON to green AVAIL.
  8. Switch APU Bleed ON.
  9. When you’re ready, change the engine selector to IGN/START, and switch on the Engine masters. I usually do engine 2 first until it’s stable and AVAIL showing on the upper ECAM, then switch on Engine Master 1.
