“…A subsequent archival study using Aviation Safety Reporting System data from 1993 to 2016 revealed that 96.5% (n 5 164) of reported UAS incidents occurred within controlled or special use airspace (Sharma, 2016). This seems to confirm the findings of Gettinger and Michel (2015), which suggested that a substantial number of incidents were clustered around large urban locationsmany of which are encompassed within highly congested Class B or C airspace.…”

A recent rash of near mid-air collisions coupled with the widespread proliferation of small unmanned aircraft systems (sUAS) raise concerns that integration is posing additional risk to the National Airspace System. In 2016, sUAS sighting reports by manned aircraft pilots averaged 147 per month. In the first three quarters of 2017, sUAS sightings jumped to 188 per month. The purpose of this study was to evaluate sUAS operator behavior to determine potential interference with aviation operations. While previous research has indeed yielded findings about operator behavior, such studies were generally based on data derived from Aviation Safety Reporting System filings or the UAS sighting report database maintained by the Federal Aviation Administration. In this study, the authors partnered with a UAS technology company to deploy an AeroScope, a passive radiofrequency detection device, to detect UAS flight activity in an urban area. While the device was limited to collecting flight information from only DJImanufactured platforms, it is estimated that the company holds a market share in excess of 70% providing a reasonable barometer for sUAS activity in the sample area. Over the 19-day sample period, the AeroScope device recorded 258 detections of 77 unique sUAS platforms. The authors assessed sUAS operator behavioral characteristics, including: UAS models, operating altitudes, preferred flying days and times, flight durations, and operating locations. The authors assessed 93 potential violations of 14 CFR 107 regulations, including controlled airspace breaches, exceeding maximum flight altitudes, and flight outside of daylight or civil twilight hours. The authors concluded that UAS activity in the sample area posed potential conflicts with a runway visual approach, created a collision hazard with three heliports, and heightened risk for visual flight rules operations underneath a controlled airspace shelf. The authors determined existing sUAS geofencing systems were ineffective at deterring sUAS activity unless they imposed flight restrictions in addition to hazard notification.

“…The Association for Unmanned Vehicles Systems International (AUCSI) estimates that in 2020 the number of UAS sold around the world could reach 4.7 million unities [1]. The Federal Aviation Administration (FAA) forecasts that in the United States, the sale of commercial UAS for private purposes will go from US$2.5 million in 2016 to US$7.0 million in 2020 [2]. Associated with these increase in the number of UAS being operated in airspaces, it raises the necessity to regulate how these vehicles are used.…”

In recent years, the number of Unmanned Aerial Systems (UAS) operating in the sky of urban centres has quite increased due to the facilities to purchase this type of vehicle. Consequently, the risk of an airborne impact between these vehicles and manned aircrafts has been target of concern with incidents been reported recently. Although the current aircrafts had been designed to support bird strikes, a collision with an UAS could be more critical, as reported in a study published by the Federal Aviation Administration (FAA) in 2016. In the present paper, a commercial aircraft Wing Fixed Leading Edge (WFLE) was first designed to support a bird strike. Then, its skin and spar thicknesses were increased so the WFLE could withstand an impact with an UAS. The safety criterion adopted was that the lithium-ion battery from the UAS could not penetrate into the airframe when the impact occurs at the airliner cruising speed. Finally, the weight from both WFLE configurations were compared so the mass increase could be quantified. During simulation, the same mass was considered for the UAS and the bird, although they were modelled using different materials. Modelling procedures were verified with test data found in other papers and the results obtained presented acceptable correlation. The UAS considered was a quadcopter configuration intended for recreational and commercial aerial photography with a 1.8 kg mass. The results showed that spar thicknesses increase were more effective than increases in the skin thicknesses.In addition to the troubles caused on airports, mid-air impacts between UAS and aircrafts has possibly occurred in the United Kingdom [3], Canada and, more recently, in Mexico.Sharma [2] has performed an investigation into UAS incidents considering reports released by the FAA and the NASA. The results have shown an increase in the number of occurrences, as indicated in tab.1.
