Multiple Choice

The blue master call light indicates which type of call?

Explanation:
On the 737 call system, colors identify where the request comes from. The blue master call light signals that a passenger in the cabin has pressed the call button to request assistance from the flight attendants. This color coding helps crew respond quickly to customer needs. A lavatory call uses a different indicator color, and a system fault would trigger a warning rather than a normal passenger call signal.
