Aircraft fires typically involve large amounts of which substance and are quick to develop with what level of heat?

• A. Water and Intense Heat
• B. Fuel and Intense Heat
• C. Oil and Mild Heat
• D. Oxygen and Mild Heat

Answer: (B)

Aircraft fires are driven by the onboard fuel supply, so they involve large amounts of fuel and develop with intense heat. Jet fuel stored in tanks and lines can feed the fire, and its hydrocarbon energy leads to rapid flame growth and very high temperatures. Water isn’t the primary factor in starting or feeding the fire; it’s used mainly to cool and suppress. Oxygen is always present in the environment, but not stored in large onboard quantities, and while oil may be involved in some systems, the main fuel that drives typical airframe fires is aviation fuel, which burns intensely rather than mildly.
