What is located under the lining cover on the door?

The space under the lining cover on the door typically houses essential components that facilitate the safe operation of the aircraft's doors. The lock/vent flap lever and escape slide lever are critical for ensuring that the door can be properly locked and vented in an emergency situation. The escape slide lever is particularly important as it activates the emergency slide deployment, providing passengers with a means of escape during an evacuation.

Having these levers located under the lining cover helps to streamline the door's aesthetics and operational safety, as they can be accessed only when necessary. This arrangement prevents accidental operation and ensures that crew members can quickly access the necessary functions during an emergency. Understanding the placement and purpose of these components is essential for cabin crew and ground personnel to effectively manage door operations in various situations.
