Matt Sloane is the CEO of SkyFire Consulting, a consulting company focused on the use of drones by public safety agencies. Started by four public safety professionals and a commercial pilot, SkyFire delivers professional level training, FAA consulting, and equipment sales and consultation. This provides departments with a one-stop-shop for starting drone programs.

Matt describes how and why public safety agencies, like law enforcement and firefighting, are using drones. We talk about regulatory requirements, the drones and sensors being employed, as well as privacy and rights issues. Matt also offers some good advice for drone owners who want to assist public safety agencies.

SkyFire offers training for agencies that want to include drones in their arsenal of tools, and Matt describes what they offer. We also note that the SkyFire Public Safety UAV Symposium will be held June 21-23, 2017, at the Hilton Fort Collins, in Fort Collins, Colorado. That event will bring together experts in drones, thermal imaging, public safety UAV operations, lawmakers, and public safety professionals to provide training on the latest information.

Matt is an FAA-certified manned aircraft pilot as well as an accomplished drone pilot. He also serves on the National Fire Protection Association’s committee on UAVs, which is working to establish the first real UAV guidelines for the fire service.

Aurora’s massive LightningStrike VTOL UAV just got one step closer to reality

The Aurora Flight Sciences LightningStrike XV-24A subscale vehicle demonstrator (SVD) aircraft test flight program was successfully completed at a U.S. military facility. The SVD aircraft is a 325 pound, Lithium battery-powered scale model of the full-size XV-24A. That flight test program is scheduled to begin in late 2018.

The XV-24A is a tilt-wing UAV using the same Rolls-Royce AE 1107C turboshaft engine used on the V-22 Osprey, to drive three Honeywell generators. The generators power 24 variable-pitch ducted fans on the wing and canard.

Three UK companies to develop new anti-UAV defence system

Blighter Surveillance Systems, Chess Dynamics, and Enterprise Control Systems are developing a fully integrated anti-UAV defence system (AUDS). This system combines Ku band electronic scanning air security radar, a stabilised electro-optic director, infrared and daylight cameras, and target tracking software. The AUDS also utilizes a directional radio frequency inhibitor and jammer system.

FAA Issues UAS Guidance for Law Enforcement

This isn’t guidance on how law enforcement can use UAS. It’s guidance on how law enforcement plays a vital role in “deterring, detecting and investigating unsafe operations.” Specifically, FAA looks to law enforcement for:

  • Witness Identification and Interviews
  • Identification of Operators
  • Viewing and Recording the Location of the Event
  • Identifying Sensitive Locations, Events, or Activities
  • Notifying FAA of incident, accident or other suspected violation
  • Evidence Collection

The guidance document Law Enforcement Guidance for Suspected Unauthorized UAS Operations is available as a PDF.

CNN strikes drone deal with FAA

In June 2014, CNN and the Georgia Institute of Technology announced they would jointly study how to operate UAVs safely and effectively. At that time, they said they wanted to share the data from the study with the FAA. CNN has now signed a Cooperative Research and Development Agreement with the FAA that allows it to share the research data with the FAA.

CNN Senior Vice President David Vigilante said, “Our aim is to get beyond hobby-grade equipment and to establish what options are available and workable to produce high quality video journalism using various types of UAVs and camera setups.”

International Consumer Electronics Show Coverage

The giant, annual International Consumer Electronics Show (CES) gives the industry a chance to display products that are available to buy now, and concepts that you may or may not be able to buy later. As you’d expect, there were a lot of drones at CES:

Quadcopter drone ‘deliberately flown at passenger airliner’ over Essex

The UK Airprox Board has released its report on the May 2014 incident where a quadcopter came close to an ATR72 on approach to runway 06 at Southend Airport. The report (No. 2014073) states:

“As the aircraft was about to intercept the ILS Glide-Slope, the pilot saw a remote-controlled quadcopter very close to the right wing-tip. The aircraft captain did not see the quadcopter but the sighting was reported to Southend ATC. The co-pilot formed the impression that the quadcopter had been flown deliberately close to the AT72 because he had seen it around 100m away as it approached from the right-hand side and made a turn to fly in the opposite direction to his aircraft, around 25m away and at the same level.”


The quadcopter operator could not be traced. Beyond that… nothing to be done.
