Fire and smoke awareness
Why fire and smoke are treated as one of aviation's most serious in-flight risks.
Because an aircraft cannot simply 'pull over', fire and smoke are treated with urgency: crew are trained to identify the source quickly, use the correct type of extinguisher, and communicate immediately with the flight deck.
Lithium battery fires in particular require specific handling, since these batteries can reignite — general aviation guidance recommends dedicated containment methods rather than only extinguishing once.
Smoke can also come from equipment faults rather than open flame; crew are trained to treat unexplained smoke or unusual smells seriously from the first sign.
Key points
- In-flight fire is treated as an emergency requiring immediate action.
- Lithium battery fires need specific containment approaches.
- Unexplained smoke or smell is never ignored.
Vocabulary
- Halon / extinguishing agent
- The type of fire-suppressing agent carried on aircraft for cabin fires.
- Thermal runaway
