Regulatory Compliance

In thee U.S., thee FAA Part 107 requires a demote pilot certificate and airspace autrization for controlled zons. In Europe, EASA regulations established aan operation autrization for flywats over buildings with thermal sensors. Mitigation: work with a certified drone services provider, obtain wavers for beyond -visual-lineed-sight flghts if needed, and conduct pre- flight Notam checs.
