Something is lacking in some pilots training to not understand the
ideal is to treat major course changes as flyby waypoints, not flyover
waypoints.

This goes back to a question I had a while back about "Complete
Reversal."

To me the question is how to give a student a criteria for leading
turns on an instrument approach. I can't tell from TERPS whether this
was ever intended; it does suggest that the framers assumed that
navaids would be flown over, rather than by.

The AIM says to lead turns on airways, but I have found no FAA
justification to lead turns on instrument approaches.

So the questions arise:
1) is it *always* safe to lead turns?,
2) is it *legal*?, and
3) will it pass checkrides?
