ACRP Report 195 is designed to assist airport operators in developing and implementing an obstruction management program to protect the airport airspace from encroachment by tall objects. The guidance will help airport staff in developing an obstruction management plan by understanding the regulatory environment, identifying obstructions, and in developing a strategy for communication with surrounding communities that will ensure airport involvement in any development issues that could result in an obstruction around the airport. The guidebook is supplemented by ACRP WebResource 7: Best Practices for Airport Obstruction Management Library, which provides reference documents, model documents, and presentation materials for obstruction management outreach. A methodology for creating a composite map of all applicable airspace surfaces is also provided, as well as examples of interactive airspace composite surface maps for small and large airports.
