Multiple Choice

The amber master call light indicates which type of call?

Explanation:
The amber master call light is dedicated to lavatory calls. When someone in a lavatory presses the call button, the system sends a signal to the cockpit and the amber master light illuminates to alert the crew that a lavatory request is in progress. This color-coding helps crew quickly identify the source of the alert among different types of calls, ensuring a prompt and appropriate response. Other types of calls are indicated by different indicators or colors, and a system fault would trigger a separate warning rather than the lavatory call light.
