In an era where sustainability and cost-efficiency are paramount, the aviation industry is turning to cutting-edge technologies to optimize aircraft fuel efficiency. Among these technologies, neural networks—a subset of artificial intelligence (AI)—are playing a transformative role. By leveraging vast amounts of data and learning from complex patterns, neural networks are helping airlines reduce fuel consumption, lower emissions, and save costs. This article explores how neural networks are being used to optimize aircraft fuel efficiency and the impact they are having on the aviation industry. An illustration of a modern aircraft utilizing neural network technology to optimize fuel efficiency by analyzing flight paths, weather conditions, and engine performance. What Are Neural Networks? Neural networks are computational models inspired by the human brain’s structure and function. They consist of interconnected layers of nodes (or "neurons") that process data, learn patte...
