Most Drones in Controlled Airspace Lack FAA Approval and a Third Fly Too High, Researchers Report

A dangerously close encounter between a camera drone and six F/A-18 Hornets flying in formation during a recent U.S. Navy Blue Angels demonstration over Detroit, Mich., confirms the latest aviation safety research released by Embry-Riddle Aeronautical University.

The study, published in the peer-reviewed International Journal of Aviation, Aeronautics, and Aerospace (IJAAA)reveals that aircraft are too often forced to share airspace with unauthorized drones. The latest frightening example of this problem took place on May 12, when video shows a camera drone encroaching on the flight path of six speeding jets performing aerobatic feats. The U.S. Federal Aviation Administration (FAA) is investigating the incident.

The vast majority of small unmanned aircraft systems (UAS) detected around Daytona Beach International Airport during a 30-day period in 2019 lacked approval from the U.S. Federal Aviation Administration (FAA), and more than one-third of those drones were flying higher than the law allows, Embry-Riddle researchers reported.

An FAA approval system for commercial and recreational drone flights in controlled airspace called LAANC (Low Altitude Authorization and Notification Capability) had been predicted to reduce noncompliant UAS operations by at least 30 percent within six months, researchers noted. “This voluntary approval process doesn’t seem to be working as expected,” said Embry-Riddle’s Dr. John M. Robbins, associate professor of Aeronautical Science.

Only 7 percent, or 19 of 271 detected DJI-type drone flights had approval from the FAA to fly in the locations and at the times they were flying, according to the study published IJAAA on April 23. In addition, 34.3 percent of the detected drones were exceeding legal altitude levels.

“Among the group flying too high, 32 were higher than 500 feet, six were detected above 1,000 feet, and three exceeded 1,500 feet, posing a real risk to manned aviation operations in the National Airspace System – particularly if most of those drones are not even authorized to be flying in controlled airspace,” said Dr. Ryan J. Wallace, assistant professor of Aeronautical Science at Embry-Riddle.

The findings are eye-opening and timely, given the FAA’s proposal to require Remote Identification – electronic tracking devices on drones, similar to the ADS-B tracking technology that is now mandatory on manned aircraft.

The research “highlights notable gaps in the effectiveness of, and compliance with existing FAA policies for integrating drones into the low-altitude region of the National Airspace System,” said Robbins, who is a co-author on the IJAAA study, along with other Embry-Riddle as well as Oklahoma State University
