Air Data Computers & Pitot Static Systems in smoke

[nomorecatering]

Could be a dumb question

Wouldn't the innards of an air data computer get contaminated by smoke particles if an aircraft spend long periods of time flying in very smoky air?

We just drove from Sydney to Melbourne one day ago with visibility down to 100 metres or less and I would say that based on the look of the cabin air filter in the car, then most certainly!

Most modern types use individual Air Data Modules for each pilot and each static probe/port. Only maybe max 18 inches of tubing from probe/Port into module..which sends electrical data to various systems using pilot static info.....not sure how susceptible ADM are to dust...but on our Airbus fleet..dont recall any issues w.r.t the Icelandic Volcano some years back....not to say of course that the both scenarios the same.
If contamination becomes an issue, at least individual Modules and hoses are relatively easy to swop out.
