The Lightning Control Panel (LCP) on the 777-200ER services which panels?

• A. 1R, 2R and 4RC
• B. 1L, 2L and 3LC
• C. 1L, 2R and 3RC
• D. 1R, 3R and 4RC

Answer: (A)

The Lighting Control Panel is the centralized control for cabin lighting circuits, and it wires to specific cabin zones that share the same lighting circuit. On the 777-200ER, the panels that fall under this control are the right-side zones in the forward and mid sections plus the aft center-right area. Those zones—1R, 2R, and 4RC—are grouped on the same lighting circuit the LCP manages, so you can adjust brightness or turn lights on/off for all those panels from the LCP. Other zones (like left-side panels or different right-side zones) are on separate circuits or controlled by other panels, which is why they aren’t listed as being serviced by this LCP.
