What is a Visual Descent Point associated with?

A Visual Descent Point (VDP) is specifically associated with non-precision approaches. It represents a defined point on the approach where a pilot can begin a descent to the runway, provided they have the required visibility to do so safely. This is particularly important in non-precision approaches because they typically do not provide the same level of vertical guidance as precision approaches.

Non-precision approaches, such as RNAV or VOR approaches, require the pilot to manage the descent and approach path primarily through visual reference rather than relying on an Instrument Landing System (ILS) glide slope. Therefore, the VDP allows the pilot to make a safe, controlled descent to the runway without having vertical guidance during the entire approach.

In contrast, precision approaches have established vertical guidance, and contact or visual approaches do not utilize the concept of a VDP.
