Project Summary

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 4200-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.
