Which action is NOT a typical part of addressing an in-flight fire warning?

• A. Follow fire suppression procedures, disconnect affected circuits if required, and divert per SOP.
• B. Notify dispatch and continue to the planned destination.
• C. Use the fire extinguisher as required and continue following SOP.
• D. Divert to the diversion field per SOP.

Answer: (D)

When a fire warning occurs, the primary goal is to control the situation quickly: follow the fire suppression procedures, isolate the affected systems or circuits if required, and reroute as the SOP dictates. You’ll typically notify dispatch to keep them informed and you’ll proceed with the planned action path only after the situation is under control. Using the fire extinguisher as needed is part of actively handling the threat, and you continue to follow the SOP for the crew’s actions.

Diverting to a predesignated “diversion field” isn’t a universal step in every in-flight fire procedure. The appropriate alternate airport is chosen based on current position, weather, aircraft capability, and fleet SOPs, rather than moving to a fixed, named field. That’s why this specific instruction isn’t a standard part of addressing a fire warning across all operations.
