On ACP, a call from the lavatory is indicated by which color?

• A. Amber
• B. Blue
• C. Green
• D. Red

Answer: (A)

On the ACP, the different colored indicators are used so crew can identify the source of a call at a glance. The lavatory call is shown with an amber light. This color is distinct from other call tones: red signals an emergency, while blue or green typically denote other routine cabin or galley/interphone calls. Amber strikes a balance by being highly noticeable without conveying urgency, which fits the lavatory situation where a passenger needs assistance but not an emergency. When someone in the lavatory presses the call button, the amber light lights up on the ACP to alert the crew, who can then acknowledge and respond.
