The future of a US House of Representatives proposal for unmanned air systems (UAS) to be allowed to operate in non-segregated airspace alongside manned aircraft from September 2013 increasingly depends on an anticipated joint conference with the US Senate where corresponding legislation favours conducting restricted access trials.
