When you import an ac model into for example Blender or Flightgear, you will see right-handed:

Backwards in aircraft: +X Right in aircraft: +Y Up in aircraft: +X

But inside the AC file itself its also right-handed, but flipped 90 degrees:

Backwards in aircraft: +X Right in aircraft: -Z Up in aircraft: +Y
