Helibase

Helitack refers to "helicopter-delivered fire resources", and is the system of managing and using helicopters and their crews to perform aerial firefighting and other firefighting duties, primarily initial attack on wildfires. Helitack crews are used to attack a wildfire and gain early control of it, especially when inaccessibility would make it difficult or impossible for ground crews to respond in the same amount of time.

The term helitack first appeared in a 1956 Los Angeles Times article, which described the "first of a series of tests—tabbed the Helitack Program—on the use of helicopters in firefighting will start next week in the San Bernardino National Forest". The word itself is a portmanteau of "helicopter" and "attack".

The incident Helibase is the location from which incident helicopter support missions are flown, and where the helicopters assigned to that base are parked, serviced, and refueled. Usually a helibase is in a field location that is close enough to the Incident Base Camp so that supplies and personnel can be ferried by ground to the helibase from the camp in a timely manner. More remote helibases (i.e., nearer the fire) can be established to maximize efficiency and reduce flight costs. Occasionally, helibases are located at a nearby airport or backcountry airstrip. The name of the base is designated by the name of the incident, though on large fires there can be multiple helibases. Helibases are staffed with a Helibase Manager, Deck Coordinator, Landing and Takeoff Coordinator, Radio Operator, and numerous subsidiary positions operating in a Helibase Operations trailer or out on the landing pads. Crash rescue capability is usually assigned to the larger helibases. An "H" in a circle designates a helibase on an incident map.

A Helispot is a location near a fire where it is safe for helicopters to land and take off. At this designated location, a helispot manager and usually a few helitack crewmembers will be onsite to coordinate landings and take-offs as well as the manifesting, loading and unloading of equipment and personnel. Helispots are temporarily located as the incident grows and can be found on ridges, meadows, parking lots – in short, any clearing suitable and meeting rotor clearance and hazard (wires, trees, etc.) avoidance requirements. Helispots are found on the incident map by filled in circles with the letters H-# next to it, the # designating what number it is.

A Helicopter drop point, or drop point is similar to a helispot, but used for depositing, often via longline, and caching supplies. Helicopters and supply vehicles use the drop point to off-load supplies at the edge of an incident for the ground teams to come by and pick up. Drop points may be located all around the fire. Wildland firefighters will usually pick up sharpened tools, pumps and hoses, water, food, radio batteries, etc. at the drop points. On an incident map, the symbol for a drop point is a filled dot with the letters D-# next to them with the # designating which number is it.
