What confirms the slide at 3L/R, on the 777-300ER, is fully inflated and usable?

• A. The Off-Wing-Deployment Indicator (ODI), seen aft of the exit, should be visible
• B. Girt bar indicator flag viewing window is yellow
• C. Cabin Door Status shows closed
• D. Emergency Light Switch status

Answer: (A)

The key thing to verify is that the overwing slide has actually deployed onto the wing and inflated, making it usable for an evacuation. On the 777-300ER, the Off-Wing Deployment Indicator (ODI) located aft of the exit becomes visible only when the slide has deployed and inflated properly. Seeing the ODI visible confirms the slide is ready for use. Other indicators don’t confirm inflation: the girt bar window relates to arming/disarming rather than inflation status; the cabin door status showing closed doesn’t prove the slide has inflated; and the emergency light switch status pertains to lighting, not slide readiness.
