FADEC, or Full Authority Digital Engine Control, is an advanced electronic system used in aircraft engines to manage their performance. It automatically controls various engine parameters, such as fuel flow and ignition timing, ensuring optimal efficiency and safety during operation. By using digital technology, FADEC can respond quickly to changes in flight conditions, enhancing engine reliability. The system replaces traditional mechanical controls, allowing for more precise adjustments and reducing pilot workload. FADEC also monitors engine health, providing real-time data that can help identify potential issues before they become serious problems. This contributes to improved maintenance and operational efficiency in aviation.
