Final answer:
Indications of an emergency call from the cabin to the cockpit include an illuminated master warning light, an aural warning, and a dedicated emergency call panel in the cockpit.
Step-by-step explanation:
When an emergency call is made from the cabin to the cockpit, there are usually several indications present in the cockpit to alert the pilots. One common indication is an illuminated master warning light, which notifies the crew that an emergency call is being made. Additionally, the cockpit might receive an aural warning, such as a chime or a tone, which serves as an auditory alert to the pilots.
Furthermore, modern aircraft often have a dedicated emergency call panel in the cockpit, which displays information about the source and nature of the emergency call. This panel might show the seat number or location of the call, as well as any distress signals or messages that the caller might have activated.
It's important to note that the specific indications can vary between different aircraft models and manufacturers, so pilots should consult the aircraft's operating manual for precise information on their particular aircraft.
