Aerospace Skeletons
Airliner Aircraft
Airliner is a simplified air transport aircraft type with automated landing gear retraction, which is not intended for use with a user-supplied mesh. For more information, see Airliner (Aerospace Blockset).

In Unreal® skeletons, all bones have six degrees of freedom. However, for simplicity, the Simulation 3D Aircraft (Aerospace Blockset) block only enables all six degrees of freedom (6DOF) for the BODY the Airliner. For the remaining Airliner bones, the block enables only one degree of freedom.
In this table, the markings indicate enabled or disabled degrees of freedom for corresponding aircraft bones. Columns X, Y, Z, Pitch, Roll, Pitch, and Yaw each correspond to one degree for the associated bone.
✔ — Degree of freedom enabled for the aircraft bone.
X— Degree of freedom disabled for the aircraft bone.
