scope:

Purpose.

This document is a standard for industry and government to establish facilities that minimize the risk to operations as much as practical. It is intended for use as a baseline document. Other facilities requirements may be contractually imposed, or with the approval of all parties, requirements from this National Aerospace Standard may be waived.

This standard consolidates and implements airfield criteria, aircraft rescue and fire fighting (ARFF) services, and aircraft hangar fire protection requirements, to establish a minimum level of risk for aircraft and personnel. These risk reductions have been extracted from Federal Aviation Regulations (FAR) {NOTE: Not to be confused with Federal Acquisition Regulations (FAR)}, National Fire Protection Association (NFPA) codes and standards, International Civil Aviation Organization (ICAO) guidance, and DOD and Service guidance.

Compatibility With Existing Regulations. Minimum facilities requirements for operations prescribed in this NAS that differ from existing statutory or regulatory requirements shall be subject to the agreement of all parties involved.

Proposals Not Meeting Standard. When the existing facilities do not meet the prescriptive portions of this document, proposals which include alternatives designed to mitigate risk shall be permitted to be introduced defining alternate means of providing adequate facilities with the approval of all parties involved.
