Agree wholeheartedly.
Just to add with another query - how do you feel about your ability to recognise certain symptoms when wearing a very good ANR headset.
I tried one last week for the first time and felt as though one of my senses had almost been removed. I do not have a "musical" ear and the props have to be pretty well out of synch at the best of times for me to twiddle the levers, however, the ANR just about totally deprived me.
Okay, hearing is not the bee all and end all of engine failure identification, far from it. But I felt uncomfortable nevertheless.
