Summary:
For the past two decades, there has been continuing policy
interest in enhancing airline in-flight security with
secondary cockpit barriers. A secondary cockpit barrier,
also known as an installed physical secondary barrier
(IPSB), typically consists of a lockable gate constructed of
metal rods, bars, and cables or similar intrusion-resistant
materials that retracts when not in use. A suitable barrier is
designed to be positioned between the aircraft cabin and the
cockpit; occupy sufficient space so that it cannot be
circumvented by going over, under, or around it; and be
resistant to intrusion, including forceful attempts to pull it
open or down or push through it. An IPSB primarily serves
as a means to prevent or deter access to the aircraft cockpit
when a cockpit door is briefly opened, for example, when a
pilot exits the cockpit to use the lavatory, when flight crew
are served food or during shift changes on long flights.
