Re Wiley Dog's point and the 'green band' - don't know about the 37 but, on the 474, having the trim in the green band is not necessarily a sign that all is well! If, for example, the FMS input is incorrect giving an incorrect green band indication , the config will NOT sound - the trim is where the FMS says it should be! Unlikely, perhaps, but Murphy is alive and well in the land of the unlikely.
