To ensure the forward-entry door is properly shut, which status of the door seals is required?

The requirement for the forward-entry door to be properly shut includes that the door seals must be in a locked, flush, and inside status. When the door is locked, it ensures that it is secured against opening during flight, which is essential for maintaining cabin pressure and safety. If the door is flush, it indicates that it is fitting snugly against the fuselage, preventing any gaps that could lead to leaks or unsafe conditions. Additionally, the inside status implies that the mechanisms within the aircraft are engaged and functioning properly to keep the door in place. Together, these conditions confirm that the door is fully operational and meets safety regulations for flight.
