What procedure must the FA follow to open the cabin doors from the interior of the ERJ 175 in emergency mode on land?

The correct procedure for the flight attendant to open the cabin doors from the interior of the ERJ 175 in emergency mode on land involves assessing conditions outside, pulling the main handle, and then raising the assist handle.

This process ensures that the flight attendant is aware of the external environment before opening the door, which is crucial for passenger safety. By assessing the external conditions first, they can determine if it's safe to open the door without putting passengers at risk, such as if there is traffic, fire, or water outside.

Once it is deemed safe, pulling the main handle activates the door opening mechanism, while raising the assist handle allows for additional leverage and helps stabilize the door during opening. This coordinated procedure maximizes safety and effectiveness when managing an emergency exit situation.

Other choices lack critical steps; some do not require the external conditions assessment, which is essential for safety. Others suggest using only part of the mechanism, neglecting the full procedure necessary to ensure that the door can be opened safely and effectively.
