Why Pilots Avoid Flying Directly Over Volcanic Ash
Ash Is Not Soft Like Smoke
Volcanic ash is made of tiny rock and glass particles that can damage aircraft instantly when inhaled by engines.
Engines Can Lose Power
When ash enters jet engines, it melts inside and coats critical parts, which can cause engines to shut down mid-flight.
Windshields Can Turn Opaque
Ash scratches cockpit windows, reducing visibility so badly that pilots may struggle to see outside.
Sensors and Instruments Can Fail
Ash can block sensors that measure airspeed, altitude, and airflow, leading to unreliable flight data.
Ash Clouds Are Hard to Detect
Volcanic ash often looks like normal clouds on radar, making it difficult to detect before entering.
Flights Reroute for Safety
Pilots immediately divert routes to avoid ash zones, even if it means delays or longer flight paths.
Safety Always Comes First
Avoiding ash protects engines, passengers, and the aircraft—making safety the top priority every time.
