What is the significance of a VDP on an approach plate?

The significance of a VDP, or Visual Descent Point, on an approach plate lies in its role as a designated location from which a pilot can safely begin their descent to the runway, assuming visual contact with the runway environment is established. The VDP provides a point that helps maintain a safe descent angle and aids in managing the approach, ensuring that pilots are positioned correctly to continue the landing phase while remaining compliant with the required minimum altitudes.

In instrument approaches, the VDP is particularly useful in transitioning from a specific altitude to the visual segment of the approach, helping pilots determine when they can expect to see the runway and thereby transition visually to a more conventional landing procedure. This point is crucial for maintaining situational awareness during the final approach phase and prevents pilots from descending too early or too late.
