What is the minimum altitude for a Non-Precision Approach at an IFR Alternate?

The minimum altitude for a Non-Precision Approach at an IFR Alternate is 800 feet and 2 statute miles. This standard is established to ensure that pilots have a safe margin for maneuvering while maintaining visual contact with the ground and obstacles in the vicinity of the airport.

In a non-precision approach, the lack of electronic glide slope guidance means that pilots must be especially vigilant in managing their descent rates and visibility requirements. The 800-foot ceiling provides a sufficient buffer for safely executing the approach while ensuring that the visibility is adequate to visualize the runway environment from a reasonable distance.

These criteria are consistent with guidelines set by the FAA to promote safety in aviation operations, particularly under IFR conditions where pilots may be transitioning from instrument flying to visual navigation as they approach their alternate airport. Thus, the specification of 800 feet and 2 miles helps maintain operational safety in such scenarios.
