| 1 | Evaluate Flight Endurance | Flight time with the thermal camera, spotlight, payload, and safety reserve installed. | At least 25–35 minutes per battery under normal operating conditions; maintain a 20% landing reserve. | Longer usable flight time reduces battery changes during active incidents and improves area coverage. | Conduct a timed flight using the complete operational payload in representative weather. |
| 2 | Check Battery Logistics | Recharge time, spare-battery quantity, charging temperature limits, and battery cycle life. | A full charge in 60–120 minutes; a documented service life of approximately 200–500 cycles. | A drone may be unavailable when batteries cannot be safely recharged or replaced quickly. | Review battery logs, charging procedures, replacement pricing, and thermal protection features. |
| 3 | Assess Thermal Imaging | Thermal resolution, temperature range, image refresh rate, and temperature measurement accuracy. | At least 640 × 512 thermal resolution, a refresh rate of 30 Hz or higher, and accuracy near ±2 °C when specified. | Clear thermal data helps crews identify hotspots, trapped occupants, and changes in fire behavior. | Compare recorded images against a calibrated reference source and test at multiple temperatures. |
| 4 | Confirm Environmental Protection | Ingress protection, operating temperature, wind tolerance, rain resistance, and dust protection. | Prefer an IP54 or higher enclosure rating, operation around −20 °C to 50 °C, and stable flight in winds up to approximately 10–12 m/s. | Firegrounds often involve heat, smoke, dust, moisture, and rapidly changing weather conditions. | Request independent test documentation and review operating restrictions in the flight manual. |
| 5 | Review Payload and Lighting | Payload capacity, gimbal stabilization, visible-light zoom, infrared capability, and spotlight output. | A stabilized payload capacity of at least 1–2 kg, optical zoom of 10× or more, and adjustable lighting for night operations. | The right payload supports search, mapping, command visibility, and safe reconnaissance without exposing crews. | Test image stability, zoom clarity, spotlight coverage, and flight time with all accessories fitted. |
| 6 | Verify Communications Reliability | Control range, latency, video transmission quality, frequency management, and loss-of-signal behavior. | A tested control range of at least 5 km in open conditions, low-latency video near 200 ms or less, and automatic return-to-home functions. | Reliable communications reduce the risk of losing situational awareness or the aircraft in complex environments. | Test urban, industrial, and partially obstructed environments while monitoring link quality and fail-safe responses. |
| 7 | Measure Deployment Speed | Time required to unpack, inspect, power up, establish communications, and become airborne. | A trained two-person team should be able to deploy the system in approximately 5–10 minutes. | Fast deployment provides commanders with aerial information during the critical first minutes of an incident. | Run repeated timed drills with standard personal protective equipment and preflight checklists. |
| 8 | Examine Maintenance Support | Inspection intervals, spare-parts availability, repair turnaround, software updates, and technical training. | Routine inspections every 25–50 flight hours, repair targets of 5–10 business days, and documented operator training. | Downtime can be more expensive operationally than the original purchase price. | Obtain service-level terms, maintenance schedules, parts lead times, and escalation contacts in writing. |
| 9 | Calculate Total Cost of Ownership | Aircraft, sensors, batteries, chargers, training, insurance, software, repairs, and replacement parts over five years. | Create a five-year cost model; annual operating costs commonly add 10–25% of the initial equipment cost, excluding major damage. | A lower purchase price may be offset by short battery life, subscriptions, downtime, or expensive repairs. | Compare at least three quotations using identical assumptions and include battery replacement cycles. |
| 10 | Confirm Compliance and Data Security | Airspace rules, pilot qualifications, remote identification, data storage, encryption, and evidence retention. | Use encrypted data transfer and storage where available, maintain flight records, and meet all applicable aviation and emergency-service requirements. | Legal or cybersecurity failures can prevent deployment and compromise sensitive incident information. | Review local aviation regulations, privacy policies, access controls, audit logs, and data-deletion procedures. |
