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:

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)
