What is the primary danger volcanic ash poses to aircraft?

Volcanic ash is abrasive and can damage aircraft engines, leading to engine failure. It also can damage other aircraft components like the fuselage and windows, and can block vital instruments.

How do airlines determine when it’s safe to resume flights after a volcanic eruption?

Airlines work closely with meteorological agencies and aviation authorities, which monitor the ash cloud’s movement and density. Flights resume when the ash cloud has dissipated from the flight paths and ash levels are deemed safe.

What rights do passengers have if their flight is canceled due to a volcanic eruption?

Passengers typically have the right to a refund or rebooking on the next available flight. Depending on the airline’s policies and the specific regulations in the passenger’s location, they may also be entitled to compensation for expenses such as accommodation and meals.

Are there any technologies that help mitigate the impact of volcanic ash on aviation?

Yes, there are several. These include improved weather forecasting, ash detection systems, and advanced aircraft engine designs that are more resistant to ash ingestion. Satellite monitoring and ground-based radar systems are also crucial for tracking ash clouds.
