There are a lot of reasons why volcano ashes in the air affect airplanes.
- Ash can for instance "blind" pilots by sandblasting the windscreen requiring an instrument landing, damage the fuselage. In addition, the sandblasting effect can damage the landing lights, making their beams diffuse and unable to be projected in the forward direction. Propeller aircraft are also endangered.
- When a plane is flying trough a cloud of ashes the planes engines might fail due to a lack of oxygen. Engines need oxygen to burn their fuel and deliver the power necessary for the engines to run. Due to the lack of oxygen in these ash clouds, the engines might fail.
- Accumulation of ash can also block an aircraft's pilot tubes (These are tools to measure fluid/airflow or velocity). This can lead to failure of the aircraft's speeds indicators. Not displaying the correct data.
- A lot of electromagnetic waves can be found in the ashes of a volcano. When a plane flies trough these the radio communication can suffer from it.
There are many instances of damage to jet aircraft as a result of an ash encounter. After the Galunggung, Indonesia volcanic event in 1982, a British Airways Flight 9 flew through an ash cloud; all four engines cut out. The plane descended from 36,000 feet (11,000 m) to 12,000 feet (3,700 m), where the engines could be restarted. On December 15, 1989 a KLM Boeing 747-400 (Flight 867) flying from Amsterdam Schiphol Airport to Anchorage International Airport encountered similar problems near Mount Redoubt (Alaska). The damage was 80 million US$; there was 80 kg ash in each turbine; it took 3 months work to repair the plane.
Recently the airspace all over Europe was closed due to the presence of volcanic ash in the upper atmosphere from the eruption of the Icelandic volcano Eyjafjallajökull.

How does the Iceland volcano affect the economy?
The Iceland volcanoes affect the economy because when planes are grounded the airlines lose billions of dollars

Volcano ash hazard can be dangerous.
Did planes crash when the volcano in Iceland erupted?
Thankfully, no. Many flights were cancelled because of this risk.
Can a volcano erupt at night when everyone is sleeping?
Yes. A volcano can erupt at any time of day or night. This does not affect a volcano.
How can a volcano affect animals?
It could kill them

Do volcano eruptions affect the volcano?
Yes, volcanic eruptions affect the volcano. The lava being pushed out and reforming affects the volcano's internal and external structure.
How did the Iceland volcano affect the landscape?
Ian is the volcano
Which volcano hazard can be dangerous to passing sir planes due to its fine, abrasive quality?
Volcano ash hazard can be dangerous.
How can a volcano affect you if you live 1000 miles away from the volcano?
The volcanic activity can alter the weather patterns. Large explosive eruptions can coat areas over 1,000 miles away in a layer of fine ash. Ash at high altitudes can pose a risk to planes in flight.
Why did the iceland volcano not cause the hot summer?
because the volcano doesn't affect the weather :)

How come the air planes didn't fly over the icelands volcano?
Because the ash from the volcano made the engines fail which would kill many many people
What the Eyjafjallajökull volcano affected?
The Eyjafallajokull volcano effected the local people in Eyjafjall and it effected the airspace aabove our heads which had stopped the planes flying and stranded people on holiday.
How the volcano in Iceland has an affect the environment?
The volcano affected the environment by sending air pollution in the atmosphere
