The FAA has enacted new regulations that went into effect on August 31st, 2016 for US based small unmanned aircraft systems UAS/UAV/drones over .55 pounds but under 55 pounds after what felt like a wild wild west of unclear rules awhile drones became very popular for both hobbyist and commercial companies including Autodesk for construction and reality capture technologies.

Both hobbyist and commercial pilots must be aware and follow all the new regulations for a much safer regulated US airspace. FAA Get Started Page

The new rules for non-hobbyist small unmanned aircraft (UAS) operations – Part 107 of the Federal Aviation Regulations (PDF 624 pages) – covers a broad spectrum of commercial uses for UAS. The regulations require certain restrictions on controlling the UAS and also certification of the pilot.

I Passed my Part 107 Exam!
After studying over 1230 pages of the newly required FAA Part 107, Knowledge Test Study Guide,  and the Pilot's Handbook of Aeronautical Knowledge I have passed my FAA commercial unmanned pilots exam last week and am now a FAA licensed commercial unmanned pilot. I wont have to take the exam again for two years. It felt as if many of the same knowledge questions in the two hour FAA exam came from the manned aircraft pilot exam and covered maps, aeronautics, weather, radio, par 107t regulations, safety, and crew management.

Unmanned aircraft usage has skyrocketed literally in our airspace in recent years and expected to grow further now that the regulations to support the safe unmanned UAS in our US airspace and many look at mapping, 3D modeling, deliveries. The sky is the limit.

Fly safe and legal.
