The CMS will display this message when smoke is detected in the LAV.

• A. LAV Smoke
• B. LAV Alarm
• C. Smoke Detected
• D. LAV Alert

Answer: (A)

When a display message is used, it should show both where the issue is and what the issue is, in a concise form. For a smoke condition in a specific area, naming the location first and then the condition makes the meaning crystal clear at a glance. “LAV Smoke” does exactly that: it identifies the lavatory and indicates smoke is present, so the crew can respond immediately with the appropriate checks and procedures. Other phrases either don’t specify location (“Smoke Detected”) or use a generic term (“Alarm” or “Alert”) that doesn’t tell you where the problem is or how urgent it is. So the direct, location-plus-condition format—“LAV Smoke”—is the best fit for a quick, unambiguous CMS message.
