Don't think it is a good idea to fly thru an ash cloud unless it is very very light particulates - submicron level? > But is that the only reason why flying through volcanic ash is impossible? Probably not impossible to fly thru and not the only reason but MIGHT be difficult to keep the plane staying up in the air after that :) > Would abrasive action on the fuselage erode the metal? Probably but I would think that the turbines would cop it as well plus the ash would probably clog up bits in the turbines. Also additional weight from ash sticking to the plane? Changes in controlling various bits of the plane? > If volcanic ash clouds are to become a regular thing, then the airline > which designs an ash-proof plane will scoop the field. Ash filters?
