Ash clouds threaten air traffic

[jcjeant]

Hi,

Does anybody know what specialised test equipment the KLM 737 was equipped with?

Yes ...
The specialised test equipement was the two engines
That's the best equipement for test if the engines will cope with ash ? environnement.
I suppose the Pitot tubes and other standard measuring devices are also parts of the specialised equipment of this KLM boeing .......
