What are the minimum weather requirements for a precision approach to an alternate airport?

The minimum weather requirements for a precision approach to an alternate airport are indeed 600 feet of ceiling and 2 miles of visibility. This standard ensures that pilots have a sufficient margin to safely conduct the approach and landing at the alternate airport in the event that the primary destination is unavailable.

The requirement is based on the need for adequate visibility and ceiling to accommodate the typical approach procedures associated with a precision approach, such as those using an Instrument Landing System (ILS). When alternate airports are considered, these minimums help ensure that pilots can safely navigate and land even under less-than-ideal weather conditions, which is crucial for flight safety.

In contrast, other choices reflect higher weather minimums that are not applicable for precision approaches as alternate airports. These higher minimums are likely associated with non-precision approaches or other specific conditions that would not apply to the minimums required for a precision approach. Understanding these standards is critical for pilots and instructors alike, as clarity on weather minimums impacts decision-making and operational safety.
