Fire weather forecast: A weather prediction specially prepared for wildland
fire control.
Fire weather station: A meteorological station specially equipped to measure
weather elements that have an important effect on fire control.
Firing out: The act of setting fire to fuels between the control line and the
main fire in burning out operations; also called burning out.
Fixed tank: A tank mounted inside or directly under an aircraft which contains
water or retardant for dropping on a fire.
Flammability: The relative ease with which fuels ignite and burn, regardless of
fuel quantity.
Flank fire: A fire set along a control line parallel to the wind and allowed to
spread at right angles.
Flare up: Any sudden acceleration of fire spread or intensification of the fire.
Unlike blowup, a flare up is of relatively short duration and does not radically
change existing control plans.
Flash fuels: Fuels such as grass, leaves, dropped pine needles, fern, tree moss
and some kinds of slash which ignite readily and are consumed rapidly when
dry; also called fine fuels.
Flash over: Rapid combustion and/or explosion of unburned gasses trapped at
some distance from the main fire front; usually occurs in poorly ventilated
topography.
Flow rate: The rate of dispensing liquid, measured in gallons or liters per
minute, or similar terms.
FM (Fox-Mike): See VHF-FM.
Foam: A fire-extinguishing chemical that forms bubbles when mixed with
water, it adheres to the fuel and reduces combustion by cooling, moistening and
excluding oxygen.
Formulation: Mixture produced and packaged by the manufacturer. Once the
formulation is diluted in the field, it is referred to as a tank mix.
