ICAO Doc 9974 “Flight safety and volcanic ash” is the baseline for the related EASA OPS rulemaking activity, aiming at publishing guidance for European operators to operate safely in airspace with known or forecasted volcanic ash contamination.
This block contains information on the potentially visible ash cloud and the phase of flight at which the encounter first occurred.
when volcanic ash is affecting Europe's airspace, can also detect and monitor other atmospheric pollutants, hence the Cessna's generic description as a "civil contingencies" aircraft.
27 maj 2011 · Volcanic eruptions eject large amounts of ash and trace gases such as sulphur dioxide into the atmosphere, often reaching the altitudes of scheduled flights. When flying through a volcanic ash cloud, ash particles enter the jet engines and can result in engine failure.
In April 2010, airspace all over Europe was affected, with many flights cancelled-which was unprecedented-due to the presence of volcanic ash in the upper atmosphere from the eruption of the Icelandic volcano Eyjafjallajökull.
26 sie 2014 · The simple answer is to avoid visible ash, and to be guided by an ash-risk zoning system to be published by volcanic ash advisory centres in London and Toulouse.
21 gru 2021 · Following an “Avoid, Avoid, Avoid” ethos, European bodies (European Commission, the European Aviation Safety Agency and Eurocontrol) severely restricted flight operations inside the volcanic ash advisory (VAA) polygon.
