Sugarloaf Regional Airport lies in Carrabassett Valley Maine, home to the second highest peak in the Pine Tree State. Located just five miles from the over 4,200-foot peak of Sugarloaf Mountain, the terrain offers challenging aeronautical approach and takeoff terrain for general aviation pilots. Recent FAA required ground-based inspections revealed obstructions to the visual approach surface areas. As the airport’s engineering consultants, Hoyle Tanner suggested utilizing drone technology to conduct an abridged version of a typical airport obstruction analysis. During the course of a single day, our in-house remote pilots used Hoyle Tanner’s Lockheed Martin /Procerus Technologies Indago Quadcopter drone to collect the tree canopy elevations for Runway 17-35. This data set was subsequently analyzed, and the canopy penetrations plotted to create actionable tree removal plans for a future construction project.
