What factors affect the rate of fire spread in an aircraft?

The rate of fire spread in an aircraft is influenced by a variety of factors that include the types of materials present, the fuel load, wind speed, and conditions surrounding the fire.

Different materials, such as upholstery, plastics, and metals, each have unique ignition and burning characteristics, which can significantly impact how quickly a fire spreads. For example, synthetic materials may ignite faster and burn more intensely than natural fibers. The fuel load—referring to the amount and type of fuel available—also plays a critical role; a higher quantity of flammable substances can lead to a more rapid and intense fire.

Wind speed affects fire behavior by providing additional oxygen, which can enhance combustion and therefore accelerate the rate of fire spread. Additionally, environmental conditions such as humidity and temperature can influence how a fire develops; higher temperatures can increase the likelihood of ignition and assist in spreading the fire.

This comprehensive understanding of various contributing factors provides insight into how rapidly a fire might spread during an incident in an aviation setting.
