With the boom in private ownership of small, unmanned aircraft systems (UAS) – as many as one million sold during the 2015 holiday season alone – the above scenario is becoming more and more likely. Even with restrictions banning UASs within five miles of airports, there are many scenarios that place rotor-based aircraft well beyond an airport’s perimeter, including: • News gathering • Terrain mapping and management • Crop and livestock management • Police, rescue and EMS operations • Sightseeing and short-distance travel To mitigate the potentially dangerous situations where UAS’s may impede a pilot’s ability to safely hover, land or launch an aircraft, Alion developed a unique Counter Unmanned Aerial System (C-UAS) capability that will scan an area to identify and safely land one or more UASs in the immediate vicinity.
