If established in a holding pattern with an assigned altitude above the minimum, what can you do when cleared for approach?

When you are established in a holding pattern and cleared for approach, the appropriate action is to descend to the minimum holding altitude. This is correct because once you receive your clearance for an approach, you are typically allowed to proceed with the descent unless otherwise instructed. The minimum holding altitude ensures that you remain safely above any terrain or obstacle in the area, while also being cleared to begin the approach procedure.

Descending to the minimum holding altitude prepares the aircraft for the descent profile required for the approach, allowing for a smoother transition from holding to the final approach. It also complies with standard operating procedures that dictate how pilots should manage their altitudes during various phases of flight, particularly during approaches where the aircraft must be aligned with the intended runway.

In contrast, options suggesting maintaining the current altitude or climbing to a higher altitude would not be advisable without explicit instructions. These actions could lead to safety issues or unnecessary deviations from the approach clearance. Additionally, waiting to descend only after receiving explicit instructions can delay your approach unnecessarily, especially when you are already cleared to descend to the minimum altitude for the approach.
