feds under pressure to open u.s. skies to drones

AP | Like many robots, the planes have advantages over humans for jobs that are dirty, dangerous or dull. And the planes often cost less than piloted aircraft and can stay aloft far longer.

"There is a tremendous pressure and need to fly unmanned aircraft in (civilian) airspace," Hank Krakowski, FAA's head of air traffic operations, told European aviation officials recently. "We are having constant conversations and discussions, particularly with the Department of Defense and the Department of Homeland Security, to figure out how we can do this safely with all these different sizes of vehicles."

There are two types of unmanned planes: Drones, which are automated planes programmed to fly a particular mission, and aircraft that are remotely controlled by someone on the ground, sometimes from thousands of miles away.

Last year, the FAA promised defense officials it would have a plan this year. The agency, which has worked on this issue since 2006, has reams of safety regulations that govern every aspect of civilian aviation but is just beginning to write regulations for unmanned aircraft.

"I think industry and some of the operators are frustrated that we're not moving fast enough, but safety is first," Krakowski said in an interview. "This isn't Afghanistan. This isn't Iraq. This is a part of the world that has a lot of light airplanes flying around, a lot of business jets."

One major concern is the prospect of lost communication between unmanned aircraft and the operators who remotely control them. Another is a lack of firm separation of aircraft at lower altitudes, away from major cities and airports. Planes entering these areas are not required to have collision warning systems or even transponders. Simply being able to see another plane and take action is the chief means of preventing accidents.

The Predator B, already in use for border patrol, can fly for 20 hours without refueling, compared with a helicopter's average flight time of just over two hours. Homeland Security wants to expand their use along the borders of Mexico and Canada, and along coastlines for spotting smugglers of drugs and illegal aliens. The Coast Guard wants to use them for search and rescue.

The National Transportation Safety Board held a forum in 2008 on safety concerns associated with pilotless aircraft after a Predator crashed in Arizona. The board concluded the ground operator remotely controlling the plane had inadvertently cut off the plane's fuel.

Texas officials, including Gov. Rick Perry, Sens. Kay Bailey Hutchison and John Cornyn, and Rep. Henry Cuellar, have been leaning on the FAA to approve requests to use unmanned aircraft along the Texas-Mexico border. FAA recently approved one request to use the planes along the border near El Paso, but another request to use them along the Texas Gulf Coast and near Brownsville is still pending.
