HC, I know you have been out of the game a while but why do you need to monitor the systems on a 175? The hierarchy is such that you never look at the ‘systems’ unless there is a reason to. The master list concept made the 175 a whole lot better than the 225. As for the mechanicals, as you say, only time will tell but it does seem a great deal less frantic than the 225. AH are being extremely cautious with the gearbox. I do hope it is a success in the long run as it is the most quiet, smooth and fast rotary machine I have ever flown. Take it to a FL and it is like a plank wing....apart from the orange suit, underwater breathing apparatus and life jacket...and the constant awareness that it is all about to go wrong...
