it wouldn;t quite fall out of the sky. Look up the 747 over Indonesia.
The ash clogged the combustion chambers and caused then to shut down as the silica built up on the nozzles. The aircraft continued to glide but lost
height. After it came down far enough into clean air the engines re-lit, and it climbed back to cruising altitude. However the same hit again, once
they got back into contaminated air.
And the same happened again. Engine fail, and descent into clean air.
When they finally came for landing, the windscreens where completely sandblasted. So it was like landing in zero viz fog.
Now today's aircraft have landing systems, gps,approach control. But this is provided that none of the antenna systems or indeed computers in the
avionics bays are not affected. Let alone the toxic gas build up in the cain air system does not cause other problems. One symptom of the 747 incident
was a strong sulfur smell in the cabin. Highly poisonous.
After the kicking the CAA and the like took last year after closing airspace, they have said now that they will not close it. Although they may need
to. But that airlines can operate if they can present a case for approval by the authority, that safe flight can be done.
Its a little too haphazard, and profit driven for me.
There will be a lot of engine repair shops looking forward to this one. As there will be lots and extra work required sooner rather than later for
performance restoration of engines cause by operation in contaminated air.
