Which ADG group corresponds to a tail height of 30 to less than 45 feet?

The correct answer pertains to the Airport Design Group (ADG) classification system, which categorizes aircraft based on their geometric characteristics, specifically wingspan and tail height. The criteria are essential for designing airport facilities, including taxiways, runways, and terminal buildings to accommodate different types of aircraft.

For tail heights ranging from 30 to less than 45 feet, this falls under ADG Group III. This classification is crucial for ensuring that airport infrastructure can safely and effectively handle aircraft within this height range, which typically includes larger regional jets or smaller commercial aircraft. Understanding these categories helps airport personnel ensure compliance with design standards and maintain safety during operations.

The other groups correspond to different height ranges, with ADG Group I covering the lowest heights (less than 20 feet), ADG Group II for tail heights from 20 to less than 30 feet, and ADG Group IV for aircraft with tail heights exceeding 45 feet. Each group serves distinct operational needs based on the dimensions of the aircraft it encompasses.
