What are the absolute approach minimums for Turboprop Non-precision landings?

The absolute approach minimums for Turboprop non-precision landings are established to ensure safety during the final approach and landing phases in conditions where precision guidance systems are not in use. For turboprop aircraft, the standard minimums are typically set at a decision height of 400 feet above ground level and a runway visual range of 1 mile. These minimums provide pilots with adequate visibility and altitude to make safe landing decisions in various weather conditions, ensuring they can adequately see the runway environment as they approach it.

Choosing 400/1 as the minimum allows pilots flying turboprop aircraft to comply with regulatory requirements while also taking into account operational considerations. It provides a balance between safety and accessibility for non-precision approaches, particularly in areas where precision approach infrastructure may not be available. These standards are crucial for maintaining operational safety in aviation, especially in challenging weather or visibility conditions.
