ash and engine technology advancement
Does anyone know has the improvement in engine technology over the years diminished the risk of volcanic ash?
Are there any recent VA incidents with newer technology engines? Has improvements to seals, lubrication methods, filtering and bleed management either by design or consequence improved the situation over the BA Indonesia or KLM Alaska events?
One must assume that volcanic ash exist globally though in minute concentrations at location far from the origin. Does a regular well diciplined maintenance program catch these events and categorise them as for example component x replaced due to normal or abnormal wear and tear or will the new measure reduce maintenance interval inspections times to cater for the apparent increase in abrasive particulate damage?
