What document outlines the planning and design requirements for airfields and heliports?

The correct answer is A, UFC 3-260-01, which stands for Unified Facilities Criteria for Airfield and Heliport Planning and Design. This document specifically provides the necessary guidelines and standards for the planning and design of airfields and heliports. It encompasses a wide range of criteria including layout, operational requirements, safety measures, and engineering considerations that need to be taken into account for effective airfield management and design.

The other options refer to different documents:

• FM 3-04.500 is a field manual focusing on aviation operations and maintenance, which does not specifically target airfield and heliport planning and design.

• AR 420-1 deals with Army facilities management and maintenance, providing policies that are broader and not exclusively related to airfield design.

• AFI 32-1032 concerns Air Force facilities and infrastructure but is more focused on facility requirements rather than the specific planning and design criteria of airfields and heliports.

Thus, UFC 3-260-01 is the key document that aligns precisely with the question about the planning and design requirements for airfields and heliports.
