Mainly the cockpit actually. Tell me what will make a jot of difference to the way it operates now as an analogue version...... Will it enable more pilot SA, I don't think so.
Actually it will, and it's not all about the glass. Greater integration of systems means the crew have less to do to manage the systems, increasing heads-out time, thereby improving both safety and SA. ATEC say that it makes a fairly large difference.
Better engines, I agree and long overdue. There are accident reports going back to the 80s that recommended the fitting of an anticipator system. I guess that is why I'm unimpressed. It could have been so much better years ago. Without the demise of some good aircrew. The turd polish only lasts a decade or so. What then? Chinook only?
It's more than just the anticipators. The engine is far more powerful, improving fuel efficiency (and therefore range/endurance), improving hot/high performance enormously, and improving safety margins. And that's the tip of the iceberg.
