How many flight attendants are required to open the flight deck door if a pilot needs to use the lavatory?

To ensure safety and security, the protocol requires that two flight attendants be present to open the flight deck door when a pilot needs to use the lavatory. This practice is in place to maintain a secure environment, as the flight deck is a restricted area. Having two flight attendants on duty not only helps manage the situation more effectively but also provides an additional layer of accountability and support. This is particularly important during critical phases of flight, as it allows one flight attendant to maintain communication with the cockpit while the other assists with the door procedure. This regulation reflects industry standards and enhances overall safety during flights.
