• High‐Tech Agricultural Equipment . Many farms are moving towards technologically advanced equipment to improve efficiency of farming which includes the use of aerial applicators ( manned aircraft and drones ) that could potentially extend into airspace of low‐level Military Training Routes .
• Future Cell Towers . Additional cell towers are needed to provide coverage in northeast North Carolina jurisdictions which could conflict with military training operational areas .
Vibration ( V ) Vibration is an oscillation or motion that alternates in opposite directions and may occur as a result of an impact , explosion , noise , mechanical operation , or other change in the environment . Vibration may be caused by military and / or civilian activities . The aviation mission at Seymour Johnson does not employ aircraft with flight characteristics that typically cause vibration such as slow flight of rotary‐wing aircraft ( helicopter ), high‐speed aircraft that produce supersonic boom events , or flight lower than 500 ft . AGL . However , the other branches of the Armed Forces utilize different aircraft that have differing operating characteristics including rotary‐wing aircraft that fly slower and have a greater potential to cause vibration . The following Vibration issues were identified :
• Vibration Impacts from Low‐Level Flight Activity . Vibration from low‐level fixed‐wing and rotary‐wing aircraft overflight in Restricted Areas , Military Operating Areas and Military Training Routes has the ability to cause physical property damage .
