Very fine volcanic ash particles (particularly glass-rich if from an eruption under ice) sucked into a jet engine melt at about 1,100 °C, fusing onto the blades and other parts of the turbine (which operates at about 1,400 °C).
One of the reasons for grounding, ash would not be thick enough for sandblasting.
Clogging of sensors possibly another and electromagnetic wave insulation would be unlikely.
These are the 4 considerations in aviation with a volcanic ash encounter. The ash exists within the troposphere so I don't know how you can fly underneath it.
Decisions would me made on economic as well as safety grounds.
I'd say economic posing as safety.
Most of these pax will still have to fly, so QF will still get the business.
Turbofans burn a lot of fuel dashing around in the low 20s
They'll be operating off design RPM and burning through that expensive black stuff. I somehow dont think selling a few muffins will cover it
