NASA to Test UAS Traffic Management Over Urban Areas

NASA has selected the Nevada Institute for Autonomous Systems in Las Vegas and the Lone Star UAS Center for Excellence & Innovation in Corpus Christi, Texas, to demonstrate NASA’s unmanned aircraft systems traffic management (UTM) system in an urban area. The drone flights will take place in and around downtown Reno, Nevada, between March and June, and Corpus Christi during July and August.

Key technologies to be demonstrated include airspace regulator Flight Information Management System, the UAS Service Supplier interface for multiple independent UAS traffic management service providers and their interface with vehicle integrated detect and avoid capabilities; vehicle-to-vehicle communication and collision avoidance; and automated safe landing technologies.

NASA and its partners, including the FAA, aim to help the drone industry understand challenges posed by flying in an urban environment. Results of the flight demonstrations will also be used to formulate future rules, policies and traffic management procedures for operating drones safely over populated areas. The flights constitute the final phase of NASA’s four-year series of increasingly complicated technical demonstrations with drones.

LSUASC Test UAS Flights With New Detect-and-Avoid Radar Technology

A new detect-and-avoid radar technology for small unmanned aircraft systems (UAS) was successfully tested earlier this month in Texas.

The Lone Star UAS Center of Excellence and Innovation at Texas A&M University-Corpus Christi (LSUASC) worked with AirRobot and Echodyne to successfully fly three drones in the same airspace over a simulated “capsized boat” in the Laguna Madre, according to a news release. This marked the first time a small UAS on-board radar successfully detected boat traffic in a major waterway along with small UAS traffic flying in the area.

The tests were completed at The Charles R. Johnson Airport in Port Mansfield, Texas. The flights were among those that took place across the nation over the last month that involved NASA, the Federal Aviation Administration (FAA) and the test sites.

During the Texas flights, An AR 180, provided by AirRobot, was equipped with the new MESA-DAA airborne sense-and-avoid radar. Echodyne created the radar for the flights, which is designed to enable beyond visual line-of-sight (BVLOS) operations for a variety of applications, including package delivery, infrastructure inspection and public safety.

“Echodyne’s airborne detect-and-avoid radar is made especially for small to medium UAS and enables safe beyond visual-line-of-site operations – in all environments and conditions,” said Jerry Hendrix, Executive Director for the LSUASC, according to the release. “Before the MESA-DAA became commercially available, there were no options for long-range radar on small to medium commercial drones.”

The flights also provided NASA with data to help improve BVLOS technology and first-responder priority operations.

“Radar is an ideal sensor technology for all sorts of scanning and imaging applications, especially when environmental conditions are less than ideal,” said Thomas Driscoll, Chief Technology Officer for Echodyne, according to the release. “Our radar thrives over other sensors in unpredictable weather conditions, can rapidly scan a broad field of view, can track Cessna-sized targets at distances greater than two kilometers, and dramatically increases situational awareness for UAS operators.”

The need for new rules and regulations in low-altitude airspace led to the creation of the Unmanned Aircraft System Traffic Management Plan (UTM), which consists of a series of activities called “Technology Capability Levels (TCL).” Each level increases in complexity.

Testing the new radar was part of NASA’s TCL 2, a national campaign focusing on flying small, remotely-operated aircraft BVLOS in sparsely populated areas to demonstrate, evaluate, and refine functional designs and UTM technology prototypes.

The next step, or TCL 3, will focus on testing technologies that maintain safe spacing between responsive and non-responsive UAS over moderately populated areas.

FAA Small Unmanned Aircraft Registration Began Dec. 21

The Federal Aviation Administration’s (FAA) Small Unmanned Aircraft System (UAS) registry went live during the day on Dec. 21, 2015. Please check the agency’s home page at www.faa.gov for updates.

In preparation for registering online, each owner must provide his or her name, home address and e-mail address.

Upon completion of registration, the web application will generate a Certificate of Aircraft Registration/Proof of Ownership that will include a unique identification number for the UAS owner, which must be marked on the aircraft.

Owners using the model aircraft for hobby or recreation will only have to register once and may use the same identification number for all of their model UAS. The registration is valid for three years.

Registration is free for the first 30 days, then $5 after that. By statute, all aircraft weighing more than 0.55 pounds (250 grams) and less than 55 pounds (approximately 25 kilograms), including payloads such as onboard cameras, must be registered.

Under this rule, owners who previously operated an unmanned aircraft exclusively as a model aircraft prior to Dec. 21, 2015, must register no later than Feb. 19, 2016. Owners of any other UAS purchased for use as a model aircraft after Dec. 21, 2015 must register before the first flight outdoors. Owners may use either the paper-based process or the new streamlined, web-based system. Owners using the new streamlined web based system must be at least 13 years old to register.

The FAA has partnered with several industry associations to educate the public about using unmanned aircraft safely and responsibly.

Remember these rules when you fly:

  • Fly below 400 feet altitude.
  • Keep your unmanned aircraft in sight at all times.
  • Never fly near manned aircraft, especially near airports.
  • Never fly over groups of people, stadiums or sporting events.
  • Never fly near emergency response efforts.

Working together, we can keep the skies safe for everyone.
