Out of curiosity, how many crews out there have actually had experience of power loss and blade errosion and are confident that they can assess correctly the risk level that results? I suppose those who have had military time in the desert might be able to drag up a 'once upon a time experience' when the symptoms were so noticeable it couldn't be anything else.
Well clear skies again in the north yet my car [valeted last night] is covered again but only 50% of yesterday's mess. Wonder what the values are for engine repair/blade renewal is versus lost revenue?
