Please look at this approach plate:
1. When do you start descending to 3900 ft? From D10 point or when established inbound?
2. Why the line after the D10 is curving. In all the approaches I saw before, the outbound line meet the inbound line at an angle?
3. Some Jeppesen approach plates had a gray area in the profile view with altitude. I searched to find an answer and i found in jeppesen intriduction that those are are called Segment Min Alt butwhich i never heard of before. Any idea?Note: I have searched the net about the curvy turn and I found that it is called a descending turn but no further explanation given.
