Impact on piston engines ??
We are now sitting in Denmark with perfect weather, forecasts show CAVOK and a closed airspace.
I can see the impact the ash has on jet turbines at high altitiudes, but how does it affect a Cessna 172 at 1000 ft ??
And finally - if the ash can damage a piston engine at 1000 ft - shouldn't I then worry about my car as well ?
