| 1 | Ingress protection | Clear, model-specific IP rating and stated test conditions. IPX7 describes temporary immersion under specified laboratory conditions; it does not by itself establish seawater suitability. | Test report identifying the exact aircraft configuration, test standard, and limitations. | Buyers operating in rain, spray, or accidental immersion scenarios. |
| 2 | Saltwater and corrosion resistance | Protection of motors, fasteners, connectors, and exposed surfaces from corrosive marine environments. | Materials list, corrosion-test details if available, and documented fresh-water rinsing and maintenance instructions. | Coastal, offshore, and marine field operations. |
| 3 | Payload and release system | Payload capacity, attachment security, and reliable operation of any release mechanism in the intended wet conditions. | Payload limits, approved accessory list, and controlled demonstration with the intended load. | Rescue-support, delivery, and marine inspection tasks. |
| 4 | Flight endurance and range | Practical flight time and control-link performance with the intended payload and operating conditions; published maximum figures may use ideal test conditions. | Test conditions, battery details, payload impact, and communication-link specifications. | Buyers planning long coastal routes or extended inspection missions. |
| 5 | Low-speed stability | Controlled hovering and handling in wind and near water, where spray, gusts, and limited landing options can affect operations. | Wind-limit specifications and a supervised flight demonstration in representative conditions. | Precision inspection and operations near vessels or shore structures. |
| 6 | Camera and sensing options | Sensor resolution, stabilization, low-light performance, and compatibility with the required inspection or search workflow. | Sensor specifications, sample imagery, data formats, and payload compatibility documentation. | Inspection, situational awareness, and search-support applications. |
| 7 | Battery and charging workflow | Battery availability, charge time, safe handling guidance, and practical support for repeated sorties. | Battery specifications, charger details, replacement cost, and cycle-life or warranty terms. | Teams requiring frequent flights and predictable field turnaround. |
| 8 | Maintenance and repairability | Access to replacement parts, repair procedures, and post-exposure inspection guidance. | Parts list, service turnaround estimates, maintenance schedule, and warranty exclusions. | Commercial operators seeking reduced downtime and lifecycle cost control. |
| 9 | Control, safety, and compliance | Failsafe behavior, return-to-home settings, operating documentation, and support for the rules applicable in the buyer’s jurisdiction. | User manual, safety procedures, firmware details, and relevant conformity documents for the destination market. | Organizations with formal operational and procurement requirements. |
| 10 | Customization and technical support | Ability to adapt payloads, workflows, or software and provide responsive support for the ordered configuration. | Written customization scope, lead times, acceptance criteria, training options, and support terms. | Buyers with specialized missions or fleet integration needs. |
