Feasibility and design of a multi-mode fuel delivery system for aircraft engine test cells in the Philippines

Abstract

This case study evaluatesinnovation management in aviation training by assessing a multimodal fuel-delivery system for aircraft reciprocating-engine test cells in the Philippines. The modular platform is designed to supportcarbureted, electronic fuel injection  EFI), and direct injection (DI) configurations, addressing capability gaps in Maintenance, Repair, and Overhaul (MRO) and academic laboratories while advancing sustainability. A design-based strategy is developed to integratethree analytical lenses: TELOS (technical, economic, legal, operational, and schedule) for feasibility; Technology–Organization–Environment (TOE) for adoption readiness; and Triple Bottom Line (TBL) for economic, environmental, and social value. Evidence is obtained from regulatory documents, international benchmarks, and semi-structured interviews with practitioners. Findings showthat the system is technically viable, cost-advantageousover multiple single-purpose rigs, and compliant with CAAP and ICAO requirements. The TOE analysis reveals strong regulatory drivers, although organizational capacity, funding, and upskilling remain uneven. The TBL findings confirmcost efficiencies, compatibility with Sustainable Aviation Fuels (SAF), and contributions to human capital development. A five-phase roadmap is proposed: alignment, pilot validation, institutional rollout, regional scaling, and national integration. Test-cell modernization is reframedas a technological and organizational innovation that enhances competitiveness and supports sustainability. Identified limitations motivateprototype development to quantify technical and economic performance.
