Final answer:
The fadecs that are masters for prop sync are typically found in aviation, specifically in aircraft engines. Prop sync is a feature that ensures all propellers on a multi-engine aircraft rotate at the same speed, reducing vibration and improving efficiency.
Step-by-step explanation:
The fadecs (Full Authority Digital Engine Control Systems) that are masters for prop sync are typically found in aviation, specifically in aircraft engines. A fadec is an electronic engine control system that manages and regulates various aspects of an aircraft engine, including propeller synchronization. Prop sync, short for propeller synchronization, is a feature that ensures all propellers on a multi-engine aircraft rotate at the same speed, reducing vibration and improving efficiency.
