"VDP: a defined point on the final approach course of a NonPrecisionApproach (straight-in) procedure from which NORMAL descent from the MDA to the RWY touchdown point may be commenced, provided the approach threshold of that rwy, or appr. lights, or other markings identifiable with the approach end of that rwy are clearly visible to the pilot."
How do you interpret "normal" if you don't follow a descent closed to a std 3°?
Cheers.
Fly safe & enjoy life.
