CEE 4674 – Airport Planning and Design (copyright A. Trani) Large Wingspan Challenges 6 ADG VI aircraft have total lengths of 230 feet today ADG VI aircraft have wingspans around 15% larger than current transports (262 feet for Airbus A380) Structural weight penalties of folding wings are unacceptable to most airlines
