Which alert provides initial notification of smoke detected?

The correct answer is the WAP notification. This alert serves as the initial warning mechanism within the cockpit to inform the crew that smoke has been detected in the aircraft. The WAP, or Warning and Alerting Panel, is specifically designed to consolidate critical alerts, including fire and smoke indications, thereby ensuring that pilots receive timely and actionable information concerning the aircraft's status.

A clear understanding of the WAP's role is essential for flight safety, as immediate response to smoke detection can be crucial in managing potential in-flight emergencies. While other alerts, such as the fire warning bell, do provide important warnings related to fire issues, the direct notification of smoke detection is categorized specifically through the WAP notification. This panel helps pilots prioritize their actions in emergency situations, making it a vital component of the aircraft's alerting system.
