What on the OHB indicates if it is properly latched?

• A. Red indicator light
• B. Green stripe
• C. Audible click
• D. Lock icon

Answer: (A)

Visual confirmation of an OHB latch is what this tests. The overhead bin latch on the Boeing 787 uses a red indicator light on the latch housing to show when the bin is fully closed and engaged. When the red light is illuminated, you have a positive, at-a-glance indication that the latch cycle is complete and the bin is secure. This provides a clear cue, especially in low-light cabin conditions or in a busy galley area. Other cues like a green stripe, an audible click, or a lock icon may be encountered in related mechanisms or procedures, but the red indicator light is the standard, reliable signal used to confirm a properly latched OHB.
