3 winters based at Keflavik and I observed fine powder-the result of the lava grit spread for friction being ground fine by aircraft wheels- being hoovered into my CFM56s giving all the appearance of white smoke in the beam of the turnoff lights.
Icelandair, Wow and others are regular inhalers of this dust, so are their engines showing signs of ingestion/cooking of silica deposits etc?
Alas the company for whom I worked, now no longer trading, ignored my observation and refused to inspect for possible effects, so I was unable pursue the issue, so will any of the locally based airlines or the regular visitors wish to follow this up?
Ezy, d'ya copy?
