Abstract
An aircraft and system of doors for providing security to a flight deck of the aircraft, and methods for operating the same, are provided. A passenger cabin is separated from a flight deck by an aisle that includes doors at either end. The doors are locked by a controller and one of the doors may only be unlocked, during a flight, if the remaining door is locked. As a result, a pilot can access a lavatory in the aisle in a secure manner. Additionally, the door closest to the passenger cabin may include a window that allows the pilots to view the passenger cabin through a peephole in the flight deck door. The controller may selectively dim or block a view through the window to prevent monitoring of the pilots' movements onto and off of the flight deck.
