Fast-drying dead or live fuels, generally characterized by a comparatively high surface area-to-volume ratio, which are less than 1/4-inch in diameter and have a timelag of one hour or less. These fuels (grass, leaves, needles, etc.) ignite readily and are consumed rapidly by fire when dry.

Highly combustible fine fuels such as grass, leaves, draped pine needles, fern, tree moss and some kinds of slash, which ignite readily and are consumed rapidly when dry.

Traffic flow that is prescribed for aircraft landing at, taxiing on, and taking off from, an airport. Usual components of a traffic pattern are upwind leg, crosswind leg, downwind leg, base leg, and final approach.

Lift that is gained when a helicopter translates from a hover into forward flight; additional lift increases with increasing airspeed and is derived by the rotor system moving into undisturbed air.

A facility which serves as a central point for one or more agencies to use in processing information and resource requests. It may also serve as a dispatch center for one of the agencies.

A line of water, or water and chemical retardant, sprayed along the ground, and which serves as a temporary control line from which to ignite or stop a low-intensity fire.

The address where the unit must be physically located, and dispatched from, during the mandatory availability period.

Disposing of cargo, fuel, water or retardant overboard to lighten an aircraft or to improve its stability.

Fire originating in or on a vehicle or mobile equipment.

The probable moisture content of fast-drying fuels which have a timelag constant of 1 hour or less; such as, grass, leaves, ferns, tree moss, pine needles, and small twigs (0-1/4").
