Research by the Teal Group suggests the UAS sector “will more than double over the next decade from current worldwide expenditures of $4.9B annually to $11.5B, totaling just over $80B in the next 10 years.”
At the hobbyist level, UAS are legal. As a kid, you may well have flown one in local parks at weekends. But commercial use of even these kits is currently banned, as a real estate agent recently found out when he attempted to add aerial views of prime properties to interior ones. The FAA grounded him.
The use of Predator drones in Iraq is the most popular view of "professional " UAS, but the aviation industry has already identified many potential private applications.
“Once people can fly UAS in the national airspace for civil and commercial purposes, whole new industries will emerge, inventing products and accomplishing tasks we haven’t even thought of yet,” said Michael Toscano, president and CEO of the Association for Unmanned Vehicle Systems International, based in Arlington Virginia. Toscano identified natural applications include oil and pipeline monitoring, crop dusting, and search and rescue, with additional unthought of opportunities  in the sensing and monitoring payloads commercial UAS will carry.
Nor are the opportunities confined to the US. The European Union acknowledges that its members are playing catch-up. As the Senate voted through the FAA bill, the EU UAS research team met in Brussels with an urgent remit to deliver a similar framework for opening up skies on the other side of the Atlantic. The target is to do so before the end of 2012 .
One warning though. The FAA bill contains no mention of the civil liberties issues that are already being voiced over a potential proliferation of “spies in the skies”
“This bill would push the nation willy-nilly toward an era of aerial surveillance  without any steps to protect the traditional privacy that Americans have always enjoyed and expected,” said Jay Stanley of the American Civil Liberties Union.
There may still be a dogfight ahead. Many, in our industry too, would even say a necessary one.
