I’ll have to disagree with you there.
In my experience it’s eaiser to go from Glass to “6” then the other way around.
You learn to work with a lot more information from day one then just “let’s wait and see what happens”.
Your picture is more complete.
You do need an instructor though that can teach the difference and doesn’t teach “6” pack techniques on glass.
And if you’re a “glass only” instructor you should be wise enough not to do that IPC in the guy’s own Bonanza in IMC if it’s old-skool.
Legal doesn’t email smart or safe.
That’s what it says in the FAR’s: this is the legal way to do it.
But there’s always the CFI who can’t resist that extra hour ‘complex’ or that extra hour ‘multi’ or that extra hour ‘actual’.
