Where is a Master Call Panel located in the aircraft?

The Master Call Panel is typically located in the forward and aft ceiling of the cabin. This placement allows for optimal visibility and accessibility for cabin crew to monitor passenger call signals. Such panels are crucial for enhancing communication between the passengers and the flight attendants, allowing crew members to respond promptly to passengers' needs during the flight.

Moreover, positioning the Master Call Panel in the cabin ceiling ensures it can be easily discovered and effectively utilized by the crew, thus contributing to overall safety and service efficiency within the aircraft. Other areas like the cockpit, under passenger seats, or in the galley are not suitable for this purpose due to the need for visibility and ease of access.
