What the spreadsheet misses
- Seguridad
- Fewer technicians hanging off 80-metre blades.
- Calidad
- High-resolution images enable year-on-year damage tracking.
- Flexibilidad
- Rope teams repair leading-edge erosion on the same visit.
- Edge cases
- Offshore weather windows; wind above limits grounds drones too.
- Customer experience
- Less turbine downtime per inspection is the operator's main gain.
- Jobs and redeployment
- Technicians move to repair, which drones flag more of.
- Regulación
- Aviation rules for drones; offshore permits.
