What should a pilot not do when they reach the VDP according to the RNAV approach chart?

When a pilot reaches the VDP, or Visual Descent Point, during an RNAV approach, it is crucial to maintain the Minimum Decision Altitude (MDA) and not descend below it. The MDA is a critical altitude that ensures the aircraft remains safe from obstacles and allows for the proper visual reference to land. Descending below this altitude before having the necessary visual cues can lead to unsafe conditions, including potential terrain or obstacle collisions.

Maintaining altitude until the appropriate visual references are established ensures safety and adheres to the standards set forth by aviation regulations. It is crucial for pilots to understand and respect the MDA as part of the approach procedure to mitigate risks and operate safely.

In this context, while increasing airspeed, changing direction, or performing a go-around could be tactical decisions based on situational awareness, none of these involve breaching the fundamental safety constraint of the MDA when reaching the VDP.
