THE BIG QUESTION:
Do composite skinned aircraft require more agent to control external fire and facilitate evacuation?
Aluminum skinned cargo flight
Traditionally, the initial focus is on extinguishing the external fuel fire to stop fuselage penetration.
Both help to assess fire conditions

“Data from this instrument can be used in research to predict the full-scale fire behavior of certain furnishings and wall lining materials. ” p. 3
“Babrauskas and Parker  deduced that the spectral distribution of this source approximates the irradiance in compartment fires, where radiation is the primary process for energy transfer.” p. 4
