In the context of wildland fire, the flaming front can be located at any position around the fire perimeter: head, flank, or rear. The flaming front is the portion of the fire front where flaming combustion dominates, which occurs only when the ash and soot particles are above a temperature of 977 F. Thus, the tip of the flame is defined as the location where the particles in the plume have cooled to 977 F or lower.
