Well said! I couldn't have said it better myself. This is the point I'm trying to get at. The G1000 always comes up with VNAV guidance on non precision approaches, and they're always telling you when to turn, how to enter procedure turns. etc. etc. It always sets up your NAV 1 when you load an approach. It depicts the approach on your map to show you where you are and where to go. It tells you if you're using the wrong NAV aid or the FAC is not set up on that NAV Aid.
All this stuff that a 6 pack doesn't do, and you learn how to use the 6 pack as a tool to fly in IMC, and you learn how to piece together the puzzle in your mind. Now imagine the day you lose all GPS signal, and you're trying to use your G1000 without the GPS... That's where it's going to show more if you can maintain the situational awareness that you had before without the big moving map.
This can tie into a VFR discussion as well. I've heard stories, and have seen students who are "iPilots" with their foreflight and their GPS dot overlay on their chart of choice. They get that amazing tool taken away from them, and their ability to actually maintain situational awareness aside from a dot on a map degrades to being entirely lost.... I wish I could say this is an exaggeration. This is what technology breeds if we're not careful to develop a student's true situational awareness that isn't on their magic little iPad or G1000, rather in their mind, and the G1000 or iPad only helps to enhance their mind's perception of their situational awareness.
As I've said in my last two posts. I would pick the G1000 over the 6 pack any day for IMC flying. Work smarter not harder. From a foundational standpoint, you can teach a student to fly G1000, but their situational awareness has the possibility stay close to nil.
