Abstract
An aircraft is equipped with an auxiliary access control barrier (AACB) to prevent access to an area of the aircraft. The AACB includes laterally extendable door panels that are slidably attached to each other to vary a width of the AACB, a hinge by which the door panels are pivotably attached to the aircraft, such that the door panels are pivotable between a deployed position, in which the door panels are positioned across the opening to prevent passage through the opening and in which the AACB has a first width, and a stowed position, in which the door panels are positioned to allow passage through the opening and in which the AACB has a second width, and one or more locks to prevent relative motion between the door panels to fix the width of the AACB and/or to secure the AACB within the opening in the bulkhead.
