Report cites 241 close encounters between pilots, drones

There have been at least 241 reports of close encounters between drones and manned aircraft that meet the US government's definition of a near midair collision, including 28 in which pilots maneuvered to get out of the way, according to a report released today.
Ninety of the close encounters involved drones and commercial jets, the majority of which had the capacity to carry 50 people or more.
Two aircraft must fly within 500 feet of each to meet the Federal Aviation Administration's definition of a near midair collision. In 51 of the incidents, the drone-to-aircraft proximity was 50 feet or less, according to the report by Bard College's Center for the Study of the Drone in Annandale-On-Hudson, New York.

The report is based on an analysis of government records detailing 921 incidents involving drones and manned aircraft between Dec. 17, 2013, and Sept. 12, 2015. Researchers cautioned that when flying at high speeds it can be difficult for a pilot to judge the distance between themselves and another object.
The majority of the incidents, 64.5 percent, were sightings of drones in the vicinity of other aircraft with no immediate threat of collision.
The FAA has previously released data on reports of drone sightings, but the Bard report is the first comprehensive analysis of the sightings by researchers outside the aviation community. Its findings are likely to fuel more debate over how much of a threat drones are to manned aircraft as the government struggles with how to reap the benefits of unmanned aircraft without undermining safety.

Most of the sightings analyzed in the report occurred within 8 kilometers of an airport and at altitudes higher than 120 meters even though the FAA prohibits flying most drones near airports or over 400 feet.
The locations with the most incidents were New York/Newark, New Jersey, 86; Los Angeles, 39; Miami, 24; Chicago, 20; Boston, 20; San Jose, 19; Washington, DC, 19; Atlanta, 17; Seattle, 17; San Diego, 14; Orlando, 13; Houston, 12; Portland, Oregon, 12; Dallas/Fort Worth, Texas, 11, and Denver, 10.
There have been no confirmed collisions between drones and manned aircraft in the US thus far. Government and industry officials have expressed concern that if a drone much like a bird is sucked into an aircraft engine, smashes a cockpit windshield or damages a critical aircraft surface area, it could cause an air crash.
