What visual indication will you see on the FA indicator for an emergency call from the flight deck?

The visual indication for an emergency call from the flight deck is a flashing red light on the FA (Flight Attendant) indicator. This specific signal is designed to immediately alert cabin crew members to the urgency and seriousness of the situation. A flashing red light is universally recognized in aviation as a signal that requires immediate attention, signifying that there is a critical issue that requires the crew's prompt response.

In contrast, other lights such as a solid yellow light or a flashing green light indicate different levels of urgency or types of communications. For instance, a solid yellow light typically indicates a routine call from the flight deck, while a flashing green light is often associated with a standard communication or alert that does not carry the same immediate implication as an emergency signal. The solid red light, meanwhile, does not apply in this context as it usually pertains to a different alert condition unrelated to emergency calls.
