Bali Flights Cancelled due to Lewotobi Volcano Nov. 2024

So the Darwin VACC envelopes appear to be some 'call' on the density of the ash plume, but they don't say what the criteria is; probably includes infra-red and other spectra to determine a 'safe' level. Never-the-less you can tell from FR24 that any plane flying into or out of DPS will encounter some ash.

If anyone has info on the methodology of the Darwin VAAC, particularly on what they use to define their envelopes, it would be interesting to know.
Following the 2010 Iceland volcanic disruption in Europe, the UK CAA decided that 4 milligrams of ash per cubic metre of air was "safe". Not sure if that determination has spread past the UK.
