Hughes can provide expert analysis of obstacles as they relate to airspace impingement for airports, heliports, architects, construction. Hughes analyzes over 50,000 obstacles annually, both protecting airspace from obstacle encroachment and saving architects time and resources in determination of proposed construction sites. We can also facilitate the required forms to complete your projects on-time with absolute accuracy.

Hughes uses several resources to determine obstacle accuracies including UAS & laser technology, stereo-optical imagery as well as robust data repositories. Hughes is authorized by the FAA to improve OEAAA obstacle database classifications to 1B/2C accuracies. With Hughes expeditious mobilization and resources, airspace constraints can be remedied quickly and accurately.

Hughes deploys the latest UAS technology with its cadre of FAA certificated survey drones, piloted by FAA certificated PEP’s.
