        Q10: What's the most dangerous part of roof inspections? Risk Analysis:

        Risk Probability Severity Mitigation
        Drone collision with building Medium High Careful piloting, observer, 5m buffer
        Loss of GPS signal Medium Medium RTK backup; manual control proficiency
        Drone falls in windy conditions Low High Wind speed limits; hover testing
        Battery failure mid-flight Low High Pre-flight battery check; spare batteries
        Signal loss (interference) Low Medium Frequency scanning; backup radio
        Operator fatigue Medium Low Limit flight time; take breaks
        Injury to third parties Low High Barriers; spotters; consent

        Key Takeaway: Roof Inspection—Best First Commercial Job

        Piyo's Observation: "So roof inspection is easier than other drone work?" Poppo's Answer:

        "Yes. It's relatively safe, financially viable (€40K+ annual profit possible), regulators are permissive, and demand is constant. If I were starting a drone business, I'd begin with roof inspections."

        Why Roof Inspections Are Ideal:

        ✅ High profit margin (70–85%) ✅ Rapid approval timeline (2–8 weeks) ✅ Established market demand ✅ Low regulatory barriers (vs. spraying/delivery) ✅ Safe operation (low altitude, predictable) ✅ Insurance affordable (€2–4K/year) ✅ Scalable (50+ jobs/year possible solo)
