Definition
A defined point on the final approach course of a non-precision straight-in approach procedure from which a normal descent from the minimum descent altitude (MDA) to the runway touchdown point may begin, provided the required visual references are in sight. The VDP is identified on the profile view of the approach chart by a bold letter 'V'.
Plain English
On a non-precision approach, the VDP is the spot along your final approach where, if you can see the runway, it is safe to start your normal descent down to land. If you cannot see the runway by then, you should not descend further from the minimum altitude.
Context Anchor
Seen on the profile view of some instrument approach charts, often shown with a V symbol near the final approach path.
Derivation
The name describes its function literally: the point at which a visual descent to the runway can begin. Worth noting because pilots sometimes assume it is a required action point; it is actually a decision aid.
Why Pilots Care
It provides a safe, standardized location to leave the MDA only when visual contact exists, reducing the chance of flying into terrain while descending.
Grounding Statement
At the VDP, the practical choice is simple: if you see what you need for landing, descend normally; if not, stay at the minimum descent altitude and be ready to go missed.
Intuition Check
A VDP is not a point where you must descend, and it is not automatic permission to descend. It is the point where descent may begin only if the required visual references are in sight.
Example Sentence 1
Approaching the VDP at the MDA, the pilot confirmed the runway environment was in sight and began a normal descent for landing.
Example Sentence 2
The approach plate showed the VDP 1.2 miles from the runway, allowing a stabilized descent once visual.
