Passengers boarding commercial aircraft often catch a glimpse inside the cockpit, although the cockpit door must remain sealed during flight as per federal law. So, why do pilots leave the door open during boarding? According to aviation experts and flight attendants, the explanation is quite simple.
Corry Lane, the director of safety at Cirrus Aviation Services, explained that pilots and flight attendants use this opportunity to communicate crucial flight details, passenger counts, fuel status, weather updates, and any last-minute changes. Keeping the door open facilitates a quicker exchange of information between the crew members and other airport staff who may need to enter the cockpit for paperwork delivery, flight plan updates, or final checks.

Flight attendant Venezia Macias corroborated this, mentioning that pilots need to handle their responsibilities and communicate with various personnel before departure. From coordinating with ground crew, gate agents, and rampers on baggage weight and balance to addressing cabin issues that may require their attention, keeping the door open ensures smooth communication flow before flight.

Once the aircraft takes off, regulations stipulate that cockpit barriers must remain sealed at all times to ensure passenger safety. The Code of Federal Regulations mandates that pilots must keep the door separating the flight crew compartment from the passenger compartment closed and locked during operation.
In response to the heightened security measures post-9/11, cockpit doors are now required to be locked during flight except for authorized personnel. However, some groups argue that additional measures, such as secondary barriers, are necessary to enhance the protection of flight crews when the cockpit door is open.
Recently, Southwest Airlines introduced its first aircraft equipped with a secondary cockpit barrier, aimed at preventing unauthorized access to the front galley adjacent to the flight deck when a pilot needs to leave the cockpit during the flight. This additional security feature is a proactive step towards ensuring the safety and security of all onboard personnel.
While hardened flight deck doors have bolstered security measures, there is an ongoing discussion within the aviation industry about the need for supplementary barriers to prevent potential threats during flight. As safety remains a top priority in aviation, airlines continue to explore innovative solutions to mitigate risks and safeguard passengers and crew members.
In conclusion, the practice of pilots leaving cockpit doors open before flights serves a practical purpose in facilitating efficient communication and pre-flight checks. However, strict regulations dictate that once airborne, cockpit barriers must be sealed to uphold safety standards. The introduction of secondary barriers by airlines like Southwest signifies an ongoing commitment to enhancing security measures and protecting all individuals onboard commercial flights.
