To work commercially, drone pilots need a RePL – Remote Pilot License which can be learned over a 5 day period and a short test. Costs can vary around the $2K – $3K for the certification. Training providers will teach you regulations, safety, air law and operating your drone safely. This includes practical flying experience as well. The second part of the certification is that the drone pilot then needs to work for a company that holds a ReOC – Remote Operator Certificate. This is an optional additional certification for businesses and companies.
