What wind speed provides optimum distribution of AFFF from the flight deck extinguishing system?

• A. 5 knots
• B. 10 knots
• C. 15 knots
• D. 20 knots

Answer: (C)

The correct answer indicates that a wind speed of 15 knots provides the optimum distribution of Aqueous Film-Forming Foam (AFFF) from the flight deck extinguishing system. At this wind speed, the foam can be effectively directed to the fire without being blown away or dissipated too rapidly. Wind speeds lower than 15 knots may not provide enough force to properly distribute and blanket the AFFF over the fire area, while higher wind speeds could cause the foam to disperse too quickly, reducing its effectiveness. The chosen speed ensures that the AFFF maintains its integrity and adheres to the flames, allowing it to form a barrier that suppresses the fire more efficiently. Overall, 15 knots strikes a balance between effective application and control of the foam during firefighting operations on the flight deck.
