Pace,
I think most if not all pilots here know the engines are not going to just stop when flying through even a red sector of ash. There is a big difference between that and the ash cloud BAW009 flew through.
My concern though is that by flying through a low density area of ash I am causing a small amount of damage to the turbine sections, bearings, small amounts of glass stuck to the blades etc
After the days work, then what ?........I hand it over to a colleague to do the next shift.
Can a quick inspection by an engineer detect these small amounts of damage without the time for a bore-scope ? I doubt it.
I know where your coming from Pace but it's the hidden danger that concerns me.
