(2) UTILITY RUNWAY. A RUNWAY that is constructed for, and intended to be used by propeller-driven aircraft of 12,500 pounds maximum gross weight and less.
(3) VISUAL RUNWAY. A RUNWAY intended solely for the operation of aircraft using visual approach procedures with no straight-in instrument approach procedure and no instrument designation indicated on a Federal Aviation Agency approved airport layout plan, a military service’s approved military airport layout plan, or by any planning document submitted to the Federal Aviation Agency by competent authority.
