Drones in wildfire management
Drones, also known as Unmanned Aerial Systems/Vehicles, or Remotely Piloted Aircraft, are used in wildfire surveillance and suppression. They help in the detection, containment, and extinguishing of fires. They are also used for locating a hot spot, firebreak breaches, and then to deliver water to the affected site. In terms of maneuverability, these are superior to a helicopter or other forms of manned aircraft. They help firefighters determine where a fire will spread through tracking and mapping fire patterns. These empower scientists and incident personnel to make informed decisions. These devices can fly when and where manned aircraft are unable to fly. They are associated with low cost and are flexible devices that offer a high spatiotemporal resolution.
The data gathered through these devices is unique and accurate as they fly low, slow, and for a long period. They can also collect high-resolution imagery and sub-centimeter data in smoke and at night. It provides firefighters access to real-time data without putting the lives of pilots at risk. Managing a 24/7-drone fleet over any huge forestland is challenging. Public drones pose a danger to wildfire and can cost lives. Fire response agencies are forced to ground their aircraft to avoid the potential for a midair collision. Policies in the United States, Canada, and Australia discourage the use of public drones near wildfires.
Description
Drones allow firefighters accurate data. By using the real-time data, firefighters can determine where a fire will move next, assisting them in making swift decisions and draw up a strategic plan about movement and evacuation.Manufacturers equip these devices with infrared cameras that capture wind direction, high-resolution imagery of smoke, and other variables. The capability to operate at a low elevation allows firefighters to use UAVs to identify quick escape routes. These are used in approving flights to monitor massive wildfires in the US Pacific Northwest and in Australia.
The use of UAVs limits exposure and reduces risk to pilots and wildland firefighters. Easily packable and able to fly in remote locations. These can fly as fast as 40 miles an hour. The drone pilots can operate the devices at varying speeds to help people better see what is happening. The transmission from drones or UAVs can be viewed on a laptop computer in a mobile ground station. A drone weighing 15 pounds and a six-foot wingspan, has a range of about eight miles and can stay in the air for an hour without recharging. The aircraft can be programmed to fly on its own, but a safety pilot will monitor operations during the tests. These also serve as tools for starting planned, controlled fires to clear out hard-to-kill underbrush. Drones are a part of fire research and management.
Drone Based Aerial Ignition
Drones have also been deployed as tools for starting planned, controlled fires to clear out hard-to-kill underbrush. It is called the "Drone Amplified Ignis System." The Ignis System uses ignition spheres, which are similar in size to ping-pong balls, but are filled with potassium permanganate powder and injected with glycol and dropped to the target site. The balls ignite about 30 seconds after injection to start a controlled fire. The at the University of Nebraska Lincoln were the to deploy an "unmanned aerial system plastic sphere dispenser" to deploy fire on a federally managed wildfire near Flagstaff, Arizona. The technology was , and the research was later commercialized and deployed globally by . Drone Amplified now has hundreds of systems deployed around the world.Drones in Wildfire Suppression
Though in early development, ultra-heavy lift drones are emerging as a transformative technology in wildfire suppression, offering rapid response capabilities, enhanced situational awareness, and the ability to operate in hazardous conditions that are often inaccessible to traditional firefighting methods. By integrating advanced sensors, artificial intelligence, and autonomous flight systems, drones are increasingly utilized for both early detection and active suppression of wildfires. Though in early stages, drone systems are now being developed to deploy fire retardants, drop water payloads or perform logistical tasks such as equipment delivery in coordination with ground crews and crewed aircraft.The increasing frequency and intensity of wildfires, exacerbated by climate change, have necessitated innovative approaches to wildfire management. Uncrewed Aerial Systems, commonly known as drones, provide several advantages in this context.Rapid Deployment: Drones can be quickly dispatched to emerging fire zones, offering immediate reconnaissance and assessment.Enhanced Safety: By operating remotely, drones reduce the risk to human firefighters, especially in dangerous or inaccessible areas.Precision Suppression: Equipped with advanced targeting systems, drones can deliver fire suppressants with high accuracy, minimizing collateral damage.Continuous Monitoring: Drones can provide real-time data on fire behavior, progression, and environmental conditions, aiding in strategic decision-making.

Integration
Drones are gradually becoming an integral part of the fight against wildfires in the United States, Canada, Australia, Europe, and Thailand.United States
The United States is experiencing longer wildfire seasons. According to the U.S. Forest Service, the changing climate has led to longer wildfire season and increased expense in fighting fires. In 2018, the President passed an executive order on wildfire management that called for an increased use of drones.In 2008, NASA's Ikhana unmanned aerial vehicle was used in the battle against more than 300 wildfires raging in California. Matrice 600 was used during the Woodbury Fire on June 8, 2019, about 5 miles northwest of Superior, Arizona. In 2013, the National Guard used a drone for the first time in Yosemite National Park to find a crew that lost connection to the commander. The drones helped in finding the crew in five minutes.
Los Angeles Fire Department first used firefighting drones 2017. In the same year, the federal firefighters used UAVs on 340 wildfires in Oregon. The firefighters made use of drones in 12 states, according to the Department of Interior. Drones were used in 2016 [California wildfires|2016 fires in California]. The drones are being used by Forest Service crews, Bureau of Land Management and the Oregon Department of Forestry.
Wildfire Management Technology Advancement Act
In March 2019, the Wildfire Management Technology Act was signed into law as Section 1114 by President Trump. The goal of the bill is to "develop consistent protocols and plans for the use of wildland fires of unmanned aircraft system technologies, including for the development of real-time maps of the location of wildland fires." The bill was introduced in 2015 after the Carlton Complex Fire.Call When Needed contract

The Dutch fire brigade together with the Dutch drone manufacturer, Avy BV are testing a long-range drone to detect & monitor early-stage wildfires for a year since February 2021. The long-range drone is equipped with a stabilized gimbal, including an RGB and a thermal camera. AI is used to recognize the fires automatically.Types
Drones come in various sizes and are equipped with a variety of specialized detectors and equipment. There are fire-starting drones that help in limiting the damage caused by wildfires. The hobbyist drones are those piloted by the public. The use of these drones over wildfires is prohibited by the authorities in the United States and Canada. These drones hinder the firefighting operations and prevent the agencies from using aerial techniques.According to the National Wildfire Coordinating Group, there are four classifications of UAS, based on their capabilities and functions, for wildland fire management purposes. This classification does include specialized aircraft and may not apply to other uses of UAS, such as in military combat. The classifications and their details are as follows:
| Type | Configuration | Endurance | Data collection altitude | Max range | Typical sensors |
| 1 | Fixed-wing | 6–14 hours | 3,500-8,000 | 50 | EO/Mid wave IR |
| 1 | Rotorcraft | NA | NA | NA | High quality IR |
| 2 | Fixed-wing | 1–6 hours | 3,500-6,000 | 25 | EO/Long wave IR |

Challenges
Drones assist in wildfire management. Different trees require a unique navigation strategy. Some drones take time to fly through densely covered grounds. Operating drones day and night in harsh weather requires an enormous effort.A hobbyist drone over a fire puts firefighting risks at a halt and creates a high risk of accidents. Public drones disrupted wildfire operations in several locations. It also forces fire response agencies to ground their aircraft to avoid the potential for a midair collision. There have been more than 100 documented cases of unauthorized drones flying over wildfires. During the Bocco Fire, firefighters had to stop their efforts when an unauthorized civilian drone flew into their airspace. A drone has invaded the airspace above a Minnesota wildfire in each of the last four years since 2016. Interference of public drones create problems for firefighting aircraft, firefighters on the ground, and the public.
