On the ERJ 175, must the manual inflation handle always be pulled as backup when opening the door in emergency mode?

On the ERJ 175, the manual inflation handle must indeed be pulled as a backup when opening the door in emergency mode. This procedure is critical for ensuring that the slide is properly deployed and inflated in case of an emergency egress situation. By pulling the manual inflation handle, crew members can ensure the slide is functional and ready for use, which is essential for the safety of passengers and crew during an evacuation.

The importance of this step lies in the fact that automated systems may not always function as expected in an emergency, so having a manual backup procedure is crucial. Following this protocol reinforces the safety measures in place and prepares the exit for immediate use. Proper training emphasizes the necessity of this action to ensure that all crew members are ready to respond effectively in emergency situations.
