| 1 | Define the mission before selecting the aircraft | Mission type, operating environment, flight duration, payload, launch location, and required response time. | Document at least three mission scenarios, such as structure fires, wildland fires, and post-incident inspection, including maximum distance, altitude, wind, temperature, and payload requirements. | Prevents paying for capabilities that are not operationally required and reduces the risk of purchasing an unsuitable platform. | Written mission profile, field-test plan, operating limitations, and environmental performance data. | High |
| 2 | Assess flight endurance and battery logistics | Usable flight time, battery charging time, spare-battery quantity, battery storage conditions, and safe return-to-home behavior. | Calculate endurance using the intended payload and reserve capacity rather than the unloaded maximum. Plan battery rotation for continuous operations and include a defined landing reserve. | Batteries are consumable components. Replacement planning, charging equipment, storage, and transport can materially increase five-year ownership cost. | Battery cycle data, charging specifications, replacement intervals, transport requirements, and cold- or heat-weather performance results. | High |
| 3 | Match sensors to firefighting decisions | Thermal imaging, visible-light resolution, optical zoom, low-light capability, temperature measurement range, image stabilization, and data export. | Verify that the thermal camera can identify heat patterns, occupants, hot spots, and re-ignition risks at the distances used by the response team. Test performance at night, through smoke, and in changing weather. | Useful, interoperable data can improve situational awareness and reduce repeat flights. Unnecessary sensor packages increase acquisition, calibration, and repair costs. | Sample thermal and visible images, calibration procedure, measurement accuracy limits, geotagging details, and export formats. | High |
| 4 | Evaluate durability and environmental protection | Ingress protection, operating temperature, wind tolerance, dust exposure, rain tolerance, corrosion resistance, and crash survivability. | Use an ingress-protection rating appropriate to the operating environment and verify the exact test conditions. Do not treat a water-resistance rating as permission to fly in every type of rain or spray. | Rugged equipment can reduce downtime and repair frequency, but over-specification can raise purchase weight and cost. Environmental limits must be compatible with local deployment conditions. | Environmental test reports, maintenance restrictions after water or smoke exposure, replacement-part pricing, and repair turnaround commitments. | High |
| 5 | Compare maintenance requirements and serviceability | Inspection intervals, propeller and motor checks, firmware updates, sensor calibration, battery health checks, repair access, and spare-part availability. | Create a preventive-maintenance calendar covering pre-flight, post-flight, periodic, and post-incident inspections. Prefer field-replaceable components where safety and manufacturer procedures allow it. | Lower maintenance downtime improves fleet availability. Easy access to parts, manuals, diagnostics, and trained technicians can reduce labor and shipping costs. | Maintenance manual, inspection checklist, fault-code documentation, parts list, technician training requirements, and historical repair data. | High |
| 6 | Calculate total cost of ownership, not purchase price | Aircraft, batteries, payloads, charging systems, software, training, insurance, regulatory compliance, repairs, storage, connectivity, and residual value. | Use a five-year TCO model: acquisition cost + operating costs + scheduled maintenance + unscheduled repairs + battery replacement + training and compliance costs − expected residual value. | A lower purchase price may produce a higher total cost if the system requires frequent battery replacement, proprietary services, specialist repairs, or extensive downtime. | Five-year cost worksheet, software and service terms, training fees, battery pricing, warranty exclusions, insurance requirements, and repair labor rates. | High |
| 7 | Verify training, compliance, data security, and future support | Pilot qualification, emergency procedures, local airspace rules, remote identification requirements where applicable, data retention, cybersecurity, software support, and upgrade paths. | Require documented operator training, scenario-based exercises, legal approval before deployment, secure access controls, and a support plan covering the intended service life. | Strong governance reduces operational, legal, and data risks. A supported and upgradeable system is more likely to remain useful as regulations and mission needs change. | Training syllabus, regulatory checklist, cybersecurity documentation, data-storage policy, software-support period, update policy, and end-of-support notice procedure. | High |
