On the 777-300ER, where is the manual inflation handle for 3L/3R?

• A. Top aft portion of door frame
• B. Top of girt, RH side
• C. Bottom of door
• D. Inside cabin

Answer: (A)

The key idea is knowing where to manually inflate a slide if its automatic system doesn’t deploy. For the 777-300ER doors 3L and 3R, the manual inflation handle is placed on the door frame at the top aft portion. This location gives quick, unobstructed access for a crew member standing at the door, and it positions the handle where pulling it can reliably trigger slide inflation without needing to reach into the doorway or down near the floor. Other locations described aren’t the standard manual inflation point for these doors, so they wouldn’t provide the intended access or function. If the slide needs to be inflated manually, you would use that top aft door-frame handle to activate the inflation mechanism.
