1. An actuatable door for an aircraft passenger suite installed within an aircraft cabin comprising:
one or more redundant rail and carriage assemblies, the one or more redundant rail and carriage assemblies coupled to a portion of the actuatable door,
each redundant rail and carriage assembly comprising:
a primary rail and carriage sub-assembly, the primary rail and carriage sub-assembly including a primary rail and a primary carriage; and
a secondary rail and carriage sub-assembly, the secondary rail and carriage sub-assembly including a secondary rail and a secondary carriage, the secondary rail being different than the primary rail, the secondary carriage being different than the primary carriage,
the actuatable door being coupled to a suite wall of the aircraft passenger suite, the suite wall including an opening configured to allow for access to the aircraft passenger suite from an open area within the aircraft cabin,
the actuatable door being configured to actuate between a stowed door position and a deployed door position via at least one intermediate door position using one of the primary rail and carriage sub-assembly or the secondary rail and carriage sub-assembly, the secondary rail and carriage sub-assembly being configured to automatically actuate the actuatable door via the secondary rail and the secondary carriage if one of the primary rail or the primary carriage of the primary rail and carriage sub-assembly fails, such that the failure is imperceptible to the operator,
the actuatable door being configured to separate the aircraft passenger suite from the open area within the aircraft cabin when in the deployed door position and provide privacy to the aircraft passenger suite,
wherein, for each redundant rail and carriage assembly, the primary rail is mounted to the suite wall, the secondary rail is mounted to the actuatable door, and the primary and secondary carriages are coupled by a coupling bridge.
