What is the correct action to take when opening the CRJ MCD from inside the aircraft?

Opening the CRJ MCD (Main Cabin Door) from inside the aircraft involves a specific procedure to ensure safety and proper operation of the door mechanism. The correct action, which is to pull the operating handle up, engages the release mechanism of the door latch and allows it to open smoothly. This upward motion is designed to unlock the door and facilitate its opening without causing any damage or unintended consequences.

This action is part of standardized operating procedures for the aircraft, ensuring that all crew members perform door operations consistently and safely. The upward pull is intuitive when considering the mechanics of the door mechanism, highlighting the importance of proper training and adherence to specific protocols for any aircraft operations.
