Volcanic Ash

ASh from the violent eruption of Hunga Tonga Volcano is slowing moving across Australia but does not appear to pose a threat to aircraft.

According to the Australian Bureau of Meteorology’s Volcanic Ash Advisory Centre (VAAC) the ash is at 42,000ft – above the usual flight levels of commercial aircraft.

Australia’s Civil Aviation Safety Authority said that “it is being monitored by the VAAC and advice is being provided to pilots and operators.”

A CASA spokesman said “we do not close or restrict airspace as a result of volcanic ash. Airlines will make individual decisions on whether or not to fly in or around ash-affected airspace or to suspend their operations.”
