300 Aerial Applications Overview

300 Aerial Applications Overview

Wildfires are dynamic, fast-moving incidents that demand equally dynamic suppression strategies. Among the many tools available to firefighters, aircraft provide a unique capability: the ability to rapidly influence fire behavior across large areas while supporting firefighters on the ground.¹˒²

Today’s aerial firefighting fleet includes helicopters, Single Engine Airtankers (SEATs), Airtankers, Large Airtankers (LATs), Very Large Airtankers (VLATs), amphibious scoopers, lead aircraft, aerial supervision platforms, and increasingly, Unmanned Aerial Systems (UAS). Working together, these aircraft deliver water, long-term fire retardants, Class A foams, and water-enhancing gels in support of coordinated suppression strategies directed through the Incident Command System (ICS).³˒⁴

Although aircraft often represent the most visible aspect of wildfire suppression, they rarely extinguish large wildfires independently. Instead, they are employed to create tactical advantages that reduce fire intensity, slow fire spread, reinforce containment lines, protect lives and property, and improve firefighter safety. Their greatest value lies in supporting ground resources by creating opportunities for firefighters to safely and effectively contain the fire.⁴˒⁵

This overview introduces the aircraft, delivery systems, suppression agents, and operational decision-making that define modern aerial firefighting. It also establishes the foundation for the more detailed discussions presented in Sections 301 through 304, including aircraft classifications, aerial delivery fundamentals, tactics and operations, and aircraft systems.

Understanding how aircraft deliver suppression agents is important. Understanding why they are employed, and when each platform offers the greatest tactical advantage, is what ultimately defines effective aerial firefighting.

300.1 Operational Definition | Influencing Fire Behavior

Throughout this chapter, the phrase influencing fire behavior refers to any aerial action intended to:

• Reduce fire intensity
• Slow the rate of spread
• Reduce spotting potential
• Reinforce containment lines
• Improve firefighter safety
• Protect lives, property, and critical infrastructure
• Create opportunities for successful containment

Aircraft rarely extinguish large wildfires independently. Instead, they alter fire behavior in ways that allow firefighters on the ground to safely and effectively contain the incident.⁴˒⁵

Lessons from the Fireline

One of the most common misconceptions about aerial firefighting is that aircraft “put out” wildfires. In reality, aircraft are most effective when they are integrated into a coordinated suppression strategy that supports firefighters on the ground. A well-placed drop can reduce fire intensity, slow the fire’s advance, or provide firefighters with the time needed to construct containment line, protect structures, or safely engage the fire. It is this integration, rather than the aircraft alone, that ultimately determines operational success.⁴˒⁵

Behind the Tactic

Every aerial drop represents a tactical decision. Experienced Air Tactical Group Supervisors (ATGS), Helicopter Coordinators (HLCOs), Incident Commanders, and pilots continuously evaluate fire behavior, fuels, weather, terrain, available resources, and firefighter safety to determine where each aircraft can provide the greatest operational benefit. Their objective is not simply to deliver water or retardant, but to maximize each aircraft’s contribution toward influencing fire behavior in support of firefighters on the ground.³˒⁴
