COCKPIT SECURITY DOOR
The Cockpit Security Door is a bullet proof reinforced door that isolates
the cockpit from the cabin passengers, avoiding non authorized people
to enter in the cockpit.
In addition, the intrusion resistant cockpit door system has been shown
to comply with all other applicable regulations, including but not limited
to:
− Static strength,
− Rapid decompression,
− Smoke evacuation and penetration,
− Required airflow, and
− Emergency ingress and egress.
Components of the intrusion resistant cockpit door system include:
− Cockpit door latch/striker/handle,
− Mechanical deadbolt,
− View Lens,
− Decompression Panel, and
− Decompression Latch.
NOTE: - The security cockpit door must be kept closed and locked at
all times during flight except to permit access and egress
according to the operator's procedures for opening, closing
and locking the door.
- Two crewmembers must be in the cockpit during all flight
phases. If one of the pilots leaves the flight deck, he must be
replaced in the cockpit by another crewmember.
