5. Dead bolt position
A totally independent three position deadbolt lock is installed on the cockpit
side, with a key lock on the cabin side. Normal position is unlocked, the
deadbolt can be single locked to allow access with the cockpit key, or double
locked to prevent the key from unlocking the door from the cabin side.
6. Decompression panels
In the event of cabin decompression, two hinged decompression panels open
outwards to equalize pressure. Each panel opening has a security grill on the
cockpit side. If an emergency evacuation via the cockpit door will be
required, release pins on the lower decompression panel can slide inward to
release the panel. This allows the panel including the security grill to be
pulled inward and removed.
