| 1 | Thermal-Imaging Multicopter | Rapid hotspot detection, perimeter checks, structure protection, and night reconnaissance. | Approximately 25–45 minutes per battery, depending on wind, temperature, and payload. | Radiometric thermal camera, visible-light camera, spotlight, and laser rangefinder. | Vertical takeoff and landing, precise hovering, high-resolution imaging, and quick deployment. | Limited coverage compared with fixed-wing systems; battery performance decreases in cold or strong wind. | Maintain separation from aircraft and personnel, monitor battery reserves, and avoid flying directly through smoke or excessive heat. | Remote pilot certification under FAA Part 107, aircraft registration, Remote ID compliance when required, and authorization for controlled airspace. |
| 2 | Long-Endurance Fixed-Wing VTOL | Large-area fire mapping, smoke-front tracking, and repeated perimeter surveys. | Approximately 2–8 hours, depending on aircraft size, weather, and sensor load. | Multispectral or thermal imaging payload, mapping camera, and high-precision positioning system. | Efficient long-distance flight, broad-area coverage, and strong mapping productivity. | Needs a suitable launch or recovery area; generally cannot hover for detailed inspection. | Use defined launch and recovery zones, establish lost-link procedures, and coordinate operations with crewed aviation. | Part 107 or an applicable public-aircraft authorization, airspace approval, Remote ID where applicable, and a waiver or approval for operations outside normal visual-line-of-sight limits. |
| 3 | Heavy-Lift Multicopter | Transporting small emergency supplies, communications equipment, water, or medical items to isolated locations. | Approximately 15–35 minutes with a substantial payload. | Cargo box, medical kit, radio relay, water or retardant test payload, and delivery winch. | Can reach steep or dangerous terrain without exposing ground crews to unnecessary travel risks. | Reduced endurance, greater kinetic risk, and stricter payload and drop restrictions. | Confirm payload security, calculate center of gravity, use exclusion zones, and prohibit uncontrolled release over people or occupied areas. | Part 107 operating rules, aircraft registration and Remote ID where applicable; transporting or dropping material may require additional FAA authorization or waiver conditions. |
| 4 | Tethered Observation Drone | Persistent overwatch from an incident command post, evacuation route, or fireline observation point. | Several hours or longer while connected to a ground power unit, subject to system limits. | Daylight and thermal cameras, spotlight, loudspeaker, and communications relay. | Continuous surveillance, stable power supply, and reduced battery-change workload. | Restricted movement, cable entanglement hazards, and vulnerability to high winds or falling debris. | Secure the tether, mark the operating area, protect the ground station, and lower the aircraft before severe wind or lightning conditions. | The operation still falls under applicable FAA rules; airspace authorization, registration, Remote ID applicability, and public-safety approvals must be assessed. |
| 5 | Communications-Relay Drone | Extending radio, cellular, or data connectivity in canyons and areas where infrastructure has failed. | Approximately 30–90 minutes, depending on relay equipment and aircraft size. | Radio repeater, mesh-network node, cellular relay, and directional antennas. | Improves coordination between incident command, field teams, and evacuation resources. | Radio-frequency interference, limited payload endurance, and dependence on line-of-sight network geometry. | Coordinate frequencies, encrypt sensitive traffic, maintain a backup communications plan, and keep the aircraft clear of emergency helicopters. | FAA operational authorization plus compliance with applicable Federal Communications Commission frequency and power rules. |
| 6 | Mapping and Photogrammetry Drone | Creating updated orthomosaics, terrain models, fireline maps, and damage assessments. | Approximately 30–60 minutes per sortie. | High-resolution mapping camera, multispectral sensor, and survey-grade positioning equipment. | Produces repeatable geospatial data for planning, resource allocation, and after-action analysis. | Smoke, changing illumination, vegetation movement, and poor ground-control visibility can reduce data quality. | Use preplanned routes, verify georeferencing, avoid flying over active crews, and protect imagery containing sensitive locations. | Part 107 or public-aircraft authorization, airspace approval, Remote ID where applicable, and a waiver if the mission requires operations beyond standard limits. |
| 7 | Night-Operations Thermal Drone | Detecting residual heat, identifying spot fires, and supporting night patrols when crewed aviation is restricted. | Approximately 25–45 minutes per sortie. | Thermal camera, low-light camera, navigation lights, and obstacle-sensing equipment. | Improves visibility of concealed heat sources and can reduce the need for hazardous nighttime ground searches. | Reduced visual depth perception, thermal clutter, smoke obscuration, and increased collision risk. | Use a trained visual observer when required, maintain anti-collision lighting, establish conservative altitude limits, and apply a documented night checklist. | FAA Part 107 permits certain night operations only when applicable lighting, training, and operational requirements are met; controlled airspace approval may also be required. |
| 8 | Confined-Space Inspection Drone | Inspecting structures, culverts, industrial sites, mines, and narrow areas after fire exposure. | Approximately 8–25 minutes per battery. | Protected camera system, thermal sensor, lighting, and collision-tolerant frame. | Reduces entry risks for firefighters and supports rapid visual assessment in unstable environments. | Short endurance, signal attenuation, dust, heat, and unreliable positioning in enclosed spaces. | Complete a structural and atmospheric hazard assessment, use a spotter, avoid energized equipment, and follow confined-space procedures. | FAA rules still apply outdoors; indoor-only flight may be treated differently, but site-owner authorization, worker-safety rules, and local policies remain necessary. |
| 9 | Multi-Drone Mapping Fleet | Rapidly updating fire perimeters and comparing multiple sectors during a large, complex incident. | Approximately 25–60 minutes per aircraft, with continuous coverage through battery rotation. | Thermal cameras, mapping cameras, automated mission software, and shared geographic information systems. | Scales coverage, reduces mapping gaps, and supports frequent updates for incident command. | Higher coordination workload, radio congestion, data-management complexity, and increased airspace conflict potential. | Use one air-operations coordinator, assign unique flight sectors, maintain positive aircraft identification, and establish immediate landing procedures. | Each aircraft and pilot must be covered by the applicable authorization; BVLOS, automated operations, and multi-aircraft control may require specific FAA approval or waiver relief. |
| 10 | Small Rapid-Deployment Microdrone | Immediate reconnaissance from a hand crew, quick visual checks, and assessment of narrow trails or fire shelters. | Approximately 10–30 minutes per battery. | Compact visible-light camera, basic thermal sensor, and obstacle-avoidance system. | Lightweight, portable, fast to launch, and suitable for teams operating far from vehicles. | Lower wind resistance, shorter range, limited sensor performance, and smaller data-storage capacity. | Keep the pilot close to the team, avoid smoke columns and rotor wash near loose ash, maintain visual awareness, and secure spare batteries from heat. | FAA registration and Remote ID requirements depend on aircraft weight and operating conditions; Part 107, airspace authorization, and emergency-incident coordination may still apply. |
