VIRGINIA DEPARTMENT OF AVIATIONAirport Obstruction Analysis

The Virginia Department of Aviation hired E&A to provide a 3-D obstruction analysis of multiple airspace surfaces utilizing unmanned aerial systems at various airports across the state. Specifically, the DOAV requested the airspace be analyzed include:•	State Licensing Airspace Standards•	FAR Part 77.1•	AC 150/5300-13A Table 3.2 •	Engineering Brief 99•	TERPS Instrument Departure Surface•	TERPS Circling SurfacesThe project was divided into two phases and included  New River Valley (PSK), Lynchburg Regional (LYH), Charlottesville Albemarle (CHO), Dinwiddie (PTB), Hot Springs (HSP), Danville Regional (DAN), New Kent (W96), William Tuck (W78), Emporia Greenville (EMV), Mountain Empire (MKJ). For each airport approximately 2,500 acres of land was laser surveyed to create the point cloud. This included the airport property transitional surface and up to 10,000-ft beyond the runway thresholds. The comprehensive analysis airspace analysis provides location of airspace penetrations, which airspace surfaces are impacted, and extent of impact. The analysis provides coordinates for the obstruction (cm level accuracy), type of obstruction (ground, vegetation, structure etc), area of obstruction, and 2D plan set for each airspace surface, and a digital file to view the pointcloud and surfaces.  The analysis allows information to be generated for the limits of removal for a stand of trees to be removed or as detailed as if individual limbs of a single tree must be removed.
