What does a red light on the cockpit annunciator panel typically indicate?

A red light on the cockpit annunciator panel signifies a warning or critical issue that requires immediate attention from the pilot. The use of red in cockpit indications is standardized across aviation to indicate serious conditions that could jeopardize the safety of the aircraft and its occupants.

This color coding is essential for quick recognition during high-stress situations, guiding the pilot to prioritize and address any potentially hazardous situations without delay. Other indicators, such as yellow or green lights, convey different statuses, generally related to caution or normal operating conditions, which do not require the urgent response signaled by a red light.

Understanding these indicators helps pilots maintain situational awareness and respond appropriately to manage threats to flight safety.
