What feature allows access to the flight deck on the ERJ 175?

The feature that allows access to the flight deck on the ERJ 175 is an electromechanical latch. This mechanism is designed to enhance security while allowing authorized personnel to enter the flight deck efficiently. Electromechanical latches offer both reliability and safety, ensuring that the cockpit can be securely locked but also easily accessed by pilots and crew members when necessary.

This method of access is in line with modern aircraft designs, which prioritize both security and operational functionality. Unlike manual locks or keys, which can be more cumbersome and less reliable, the electromechanical latch combines electronic and mechanical components, allowing for effective locking and unlocking operations while maintaining a secure environment on the flight deck.
