Keep Eye on Skies for Drones

FAA under pressure to open US skies to drones

    Look, up in the sky! Is it a bird? A plane? No, it's a drone, and it could be coming to the friendly skies above your D.C.-area neighborhood.

    Unmanned aircraft have proved their usefulness and reliability in the war zones of Afghanistan and Iraq. Now the pressure's on to allow them in the skies over the United States.

    There are no-fly zones around the Washington region that would limit where any drones could go. But the suburbs would be fair game if civilian aircraft is already allowed.  It's also possible that the restrictions on government-owned drones over Washington may be more lax if law enforcement officials have their way.

    However, this all hinges on the Federal Aviation Administration.

    The FAA has been asked to issue flying rights for a range of pilotless planes to carry out civilian and law-enforcement functions but has been hesitant to act. Officials are worried that they might plow into airliners, cargo planes and corporate jets that zoom around at high altitudes, or helicopters and hot air balloons that fly as low as a few hundred feet off the ground.

    On top of that, these pilotless aircraft come in a variety of sizes. Some are as big as a small airliner, others the size of a backpack. The tiniest are small enough to fly through a house window.

    The obvious risks have not deterred the civilian demand for pilotless planes. Tornado researchers want to send them into storms to gather data. Energy companies want to use them to monitor pipelines. State police hope to send them up to capture images of speeding cars' license plates. Local police envision using them to track fleeing suspects.

    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.

    Michael Barr, a University of Southern California aviation safety instructor, said the matter should not be rushed.

    "All it takes is one catastrophe,'' Barr said. "They'll investigate, find they didn't do it correctly, there'll be an outcry and it will set them back years."
