The Eyjafjallajökull volcano in Iceland erupted in 2010, spewing large amounts of ash into the atmosphere. This caused major disruptions to air travel across Europe. Hundreds of thousands of passengers were stranded in airports across multiple countries. The economic damage was estimated at $1.4 billion US dollars. Individual airlines like British Airways and Air France-KLM reported losses of $20 million per day during the most disrupted period. A longer shutdown could have bankrupted some aviation companies. The eruption also disrupted international trade, especially for perishable goods and time-sensitive deliveries that could not withstand delays.

Why Iceland's Minor Volcano Is a Major Problem ?

2.  Close the viewing angle of the ashes in the case of engines or engine stop which
measure pitot tube speed and by passing the wrong data of high planes feared
caused it to fall.

4. Hundreds of thousands of
passengers had to wait in
airportsUnited Kingdom, Ireland, Scotland,
Denmark, Norway, Sweden,
Belgium, Netherlands, Finland,
France, Germany and Poland….

5. WHAT WAS THE ECONOMIC
DAMAGE ?
Due to numerous offsetting factors, it is difficult
to determine the overall economic impact on the
airline industry. for example, the International
Airtransport Association (IATA) evaluates that
the shutdown caused the demand for aircraft
fuel to fall by 1.2 million barrels,saving around
110 million us dollars nevertheless,Oxford
Economics (2010) estimates the total financial
impact at about 1.4 billion us dollars.
British Airways and Air France-Klm reported a
loss of 20 million pounds per day during the five
most disruptive days .the extensive losses
suffered by the airline industry in a week of
suspended flights, indicate that a longer
shutdown could easily send aviation companies
into bankruptcy (COLLAPSE)

International Trade
The air transport disruptions had serious
consequences for international trade.
Although some trade can be postponed,
other products such as perishable goods and
important parts and equipment can not
withstand a delay in transportation.
Deferring the trade of these products results
in lost revenue for producers and potentially
for customers relying on their delivery.
Many African countries are the producers of
perishable goods such as flowers, fruits, and
vegetables.
