Airplane Engine Noise Before Takeoff: Nothing to Worry About, Says Expert

Airplane Engine Noise Before Takeoff: Is It a Problem? Many air travelers experience anxiety when they hear unusual noises from an airplane. Recently, a video by aeronautical engineer Lucas Bernacer (@lucasbernacer) went viral, explaining a common sound often mistaken for engine trouble. Bernacer, an expert in aviation engineering, states, "The noise comes from the fan blades, which have some play and move in the wind when the engine is off." He emphasizes that this "windmill effect" is entirely normal and safe. This simple explanation alleviates passenger concerns and highlights the importance of understanding aircraft mechanics. The video's popularity underlines the public's interest in such information and its potential for broader dissemination.
