Neither the test regime nor the test site locations have been decided, but language within the bill stipulates that the test programme will run for five years. UAVs operating in US airspace are restricted to small operating areas set aside specifically for their use. While heavy UAV users include the Department of Defense, various law enforcement agencies and research institutions, stringent airspace regulations prevent the commercial operations long forecast for unmanned aircraft.
The FY2013 FAA reauthorisation bill mandates that the agency draw up a comprehensive plan to integrate UAVs into the national airspace within 270 days of enactment, or September 2013. A proposed rulemaking plan for UAVs weighing under 2kg (4.4lb), operated by government or law enforcement entities, is due "in late spring."
Other language in the reauthorisation states that UAVs are to be integrated into national airspace by September, 2015, but details remain open for interpretation.
"The act mandates that we have safe integration, not full integration, into the NAS by 2015," says the FAA.
