That is a tricky one! Where does the liability lie if damage is sustained flying through hailstones in a known area of thunderstorm activity which we operate through on a regular basis.
Where does liability lie with Bird ingestion through known migration paths or at sea based airports?
What is the difference other than the two above have caused loss of life and known engine damage while to date there has been no loss of life caused by Ash in even dense encounters in over 50 years of aviation.
There is far more risk to crashing on landing and takeoff and loosing your life within acceptable wind and shear limits than ever being killed by an ash encounter. Maybe we should call for zero wind for takeoff and landing in the next safety based campaign
