Assessing the Feasibility of Blended Wing Body Aircraft Operations at Philippine Airports: A Case Study of Clark International Airport

Abstract

Blended Wing Body (BWB) aircraft offer significant advancements in fuel efficiency, noise reduction, and environmental sustainability. This study assesses the feasibility of BWB operations at Clark International Airport, a key aviation hub in the Philippines, by examining the readiness of its infrastructure, economic viability, and environmental impact. Using a mixed-methods approach, which includes technical analysis, expert interviews, and operational simulations, the study finds that substantial modifications are necessary to meet Clark International Airport’s 3,200-metre runway requirements while also satisfying BWB take-off and landing requirements. Key upgrades include taxiway widening, apron expansion, and terminal modifications such as dual or triple jet bridges. Specialised Ground Support Equipment (GSE) and green airport technologies, such as ground power units (GPUs) and renewable energy systems, are crucial for sustainability. Despite high initial investments, economic analysis indicates long-term benefits, including increased efficiency, passenger capacity, and economic growth. Regulatory alignment with the Civil Aviation Authority of the Philippines (CAAP) and the International Civil Aviation Organization (ICAO) standards is crucial for integration. While international airports are adapting to next-generation aircraft, Clark International Airport must address infrastructure and policy gaps to remain competitive. The study concludes that with phased upgrades and sustainability initiatives, Clark International Airport can support BWB aircraft. Future research should examine regional airport readiness, regulatory adaptations, and detailed cost-benefit analyses to advance sustainable aviation in the Philippines.
