It's all dependent on what position the Fetzer valve is in.
You remember from your basic systems training the valve
that's downstream of the bypass line, RIGHT? So of course
a higher setting will get you less dings on your aural's.
If you are getting too many false icing alerts, any mechanic
worth his salt can remedy the valve problem with ball bearings
and a small hammer....... http://youtu.be/4prqDn7QS8I
