Danger: Volcanic Ash

Volcanoes can release massive amounts of material into the atmosphere, posing various dangers. The 2010 Iceland eruption, though minor, caused a significant ash cloud that disrupted European air travel. In 1982, Captain Eric Moody experienced engine failure after flying through volcanic ash, highlighting the dangers of ash to aircraft. The incident demonstrated how ash can melt in engines, causing them to fail. These events underscore the importance of understanding volcanic ash hazards to aviation safety.

What was the main consequence of the Icelandic volcanic eruption in 2010?

• It led to a significant earthquake.

• A giant ash cloud disrupted air travel.

• Lava flows destroyed nearby towns.

• The eruption caused a tsunami.

What unusual phenomenon did Captain Eric Moody observe during his flight?

• A sudden drop in cabin pressure.

• An electrical phenomenon on the wings.

• A loud explosion from the cargo hold.

• A bright flash of light in the cockpit.

What caused the engines of Captain Moody's plane to fail?

• Volcanic ash entering the engines.

• A severe thunderstorm.

• A mechanical malfunction.

• A bird strike.

How did the engines of Captain Moody's plane restart?

• The engines never restarted.

• The crew manually restarted them.

• The ash melted and cleared, allowing them to restart.

• A backup system was activated.

What lesson was learned from Captain Moody's experience?

• Aircraft should avoid flying through ash clouds.

• Engine failures are always due to mechanical issues.

• Volcanic ash is harmless to aircraft.

• Pilots should rely solely on radar during flights.
