Civil and Commercial Unmanned Aircraft Systems introduces readers to the uses of civil and commercial Unmanned Aircraft Systems (UAS), sometimes called domestic drones. We are currently experiencing revolutionary changes in aviation due to the rapid implementation of UAS. New paths to airspace access are opening up in the United States and around the world. UAS operations are surging, creating jobs, new benefits, and new challenges for society. Civil missions are performed by civilian government, also known as the public sector. Civil customers may include law enforcement, first responders, public universities, and scientific researchers, among others. Commercial missions are performed by the private sector or individuals. While not strictly commercial, this book also covers personal and recreational UAS.
