This ACC on-demand webinar will provide an overview of the collection of airport obstruction data, fundamentals of airspace obstruction terminology, regulation, evaluation, and finally, a discussion of obstruction management - including impacts and solutions. Obstruction data collection has traditionally required obtaining aerial photography, with stereo pairs and aerial triangulation to produce a data set composed of both ground and top elevations of trees and other objects. This method remains valid for obstruction analysis, but new methods using LIDAR and other newer technologies are proving useful, with the potential for improved data accuracy. Once the data  collected, the various airspace surfaces are evaluated. The traditional CFR Part 77 Imaginary Surfaces used in master planning are not necessarily the surfaces that will be cleared.

The second component of this 90-minute session will focus on the appropriate clearance surface-based FAA airport design standards outlined in the updated guidance in Advisory Circular 150/5300-13A (and Draft 150/5300-13B) and Engineering Briefs 99A and 100A. 

Lastly, once the obstruction evaluation and associated Obstacle Action Plan (OAP) are complete, you will learn what the potential impacts and solutions of implementation are, as obstruction removal and vegetation management can be a significant challenge for airport sponsors.  


At the end of this ACC on-demand webinar, you will be able to:
• Identify projects that may benefit from the acquisition of obstruction information.
• Compare various methods to acquire and apply obstruction data.
• Determine and prioritize the various surfaces that can impact an approach area.
• Develop an obstruction mitigation plan to support environmental review, acquisition of property rights, and ultimately, obstruction removal.
