How is altitude determined in Class E airspace at Statesboro Bulloch County Airport?

In Class E airspace, altitude is determined based on the specific characteristics of the airspace and the approach to it. For the Statesboro Bulloch County Airport, which is within a Class E airspace area typically associated with an airport, the altitude is generally set at 700 feet above ground level (AGL).

This altitude is standard for specific operational reasons, including separation from other airspace classes and to manage local traffic effectively. Adding 700 feet AGL ensures that aircraft are operating at a safe altitude above the ground, allowing for clearance over terrain and obstacles commonly found in the vicinity of the airport. Additionally, this altitude offers ample vertical space beneath the controlled airspace for visual flight rules (VFR) operations while integrating seamlessly with surrounding airspace, such as Class G, which operates below it.

The other options for adding different feet above ground level would not align with the typical structure and operational guidelines for Class E airspace, thus establishing 700 feet AGL as the appropriate altitude for this scenario.
