Why don't radars work over the ocean? 🌊✈️ Have you ever wondered why aircraft seem to vanish when flying over vast oceans? The secret lies in the limitations of land-based radars! 🌎 These radars can only track aircraft within a range of 320 kilometers - after that, the curvature of the Earth hides the plane from view, creating 'blind spots' over open waters. Covering the entire ocean would require hundreds of radar stations, which need land 🌍 to operate, making this coverage nearly impossible. But don't worry - modern technology has filled in the gaps! Satellites 🛰️ now provide precise tracking from above, giving accurate locations for ocean-crossing flights. Additionally, onboard radars with shorter ranges help planes detect one another, ensuring safe distances and avoiding collisions. 🛩️ And even if planes can’t be seen by land-based radars, pilots have other ways to communicate 📡 with air traffic control. High-frequency radio waves reflect off the ionosphere, allowing these signals to travel over the Earth's curve and maintain contact even when out of radar range. Thanks to these advances, flights stay safe and monitored, even over the world's most remote ocean stretches! 🌊✨
