On certain instrument approach plates, there is a charted VDP, given to tell you when you should begin your descent to the airport on a 3 deg glide slope assuming the field is in sight? This seems pretty important, so why don't all approach plates have them? Also, is it something mandatory to go by, or is it just to provide better situation awareness to the pilot? What if I pass the VDP but not the MAP and then I get the field in sight?
- I just posted a rather lengthy comment that addresses VDPs under the thread for Visual Descent Angles. It might be what you're looking for...
