What is the minimum required visibility to continue an approach?

The minimum required visibility to continue an approach typically refers to the visibility requirements outlined by aviation regulations, which are crucial for ensuring that pilots can safely land an aircraft. When a pilot approaches an airport, they must adhere to specific visibility standards depending on the type of approach being executed and the weather conditions.

In this context, choosing 1500 feet is correct because it aligns with standard visibility requirements for non-precision instrument approaches in many jurisdictions. For an instrument approach, where pilots rely on instruments to guide them, 1500 feet of visibility ensures that they can adequately see and identify the runway and other critical navigational information required for a safe landing.

Generally speaking, lower visibility minimums such as 1200 feet might apply in certain specific conditions or for specific approach types, but in broader regulation, 1500 feet is often seen as a safe standard for pilots to continue an approach without compromising safety. Therefore, 1500 feet as a minimum visibility requirement helps maintain safe operational standards during landing phases.
