What should be done if smoke or fumes are detected during flight?

When smoke or fumes are detected during flight, completing the necessary checklists is the appropriate course of action as it ensures a systematic and safe response to the emergency. The checklists relevant to smoke or fumes will guide the pilot through critical steps, such as identifying the source, managing cabin pressure, and determining the best actions to mitigate the situation.

These checklists are part of the aircraft's standard operating procedures and are designed for safety and efficiency in handling such emergencies. By following these structured protocols, the crew can maintain control of the aircraft, prioritize the safety of all on board, and communicate effectively with air traffic control if needed, all while making informed decisions.

In situations where smoke or fumes are present, it is essential to stay calm, assess the situation using the checklists, and respond appropriately based on the guidance provided therein. This approach helps to ensure the safety of the flight rather than acting impulsively or disregarding the issue.
