Proposta de modernização do sistema principal de iluminação de cabine de passageiros em aeronave comercial regional

Abstract

In recent decades, the aeronautical sector has sought technological solutions that reconcile energy efficiency, sustainability, and passenger comfort. In this context, the cabin lighting sys- tem plays a fundamental role in the onboard experience and operational efficiency of aircraft. This work presents a proposed modernization project for the main passenger cabin lighting system of a regional commercial aircraft, replacing the current fluorescent lamp-based system with an LED technology solution. It is estimated that the adoption of LED technology will reduce electricity consumption by 72.12% and the total mass of the lighting system by 15.62%, further reducing maintenance needs (life cycle cost of LED lamps at USD 12,576, compared to USD 26,084 for current lamps over a 10-year period), resulting in greater reliability, design flexibility, and the promotion of sustainable development. This work represents part of a larger project for an aeronautical company and, therefore, is limited to the initial stages of the product development process, adapted to the guidelines of the aeronautical standard ARP4754A, including the diagnosis of the existing system, requirements gathering, comparative analysis, and technical planning of the new lighting architecture.
