Question 1

How does the Flight Deck door respond to pressurization decompression events?

Answer 1

• Two decompression panels that allow air to vent from the Passenger Cabin
  into the Flight Deck in the event of a rapid decompression in the Flight Deck.
  -In the event of a Passenger Cabin decompression, the entire Flight Deck door may open, permitting Flight Deck air to vent into the Passenger Cabin.
  -In the case of a rapid decompression in the cabin compartment, the NG Flight Deck door is
  designed to withstand the pressure difference due to the small area of the flight compartment
  without opening.
