Public Outreach and Engagement

As part of implementing performance-based navigation projects, we develop consistent methodologies for communicating and developing relationships with local communities and stakeholders. Using our innovative, proprietary Volans 3D visualization tool to engage stakeholders, we help technical and non-technical audiences understand complex data. Volans provides aircraft operation and flight procedure analysis to support environmental and noise impact studies, design new departure and arrival procedures, perform air safety studies, create video presentations for education and community outreach, and analyze air space restrictions and obstructions. Our customers include ANSPs such as FAA, NavCanada, and DGAC France, and U.S. airports including Minneapolis St. Paul, Dallas/Ft. Worth, and San Diego.
