Draft Series 150 Advisory Circulars (ACs) for Airport Projects

Provides guidance for using the standardized International Civil Aviation Organization (ICAO) method to report airport pavement strength, the Aircraft Classification Number – Pavement Classification Number (ACN-PCN) method. Provides guidance for reporting changes to airport data that is generally published on Form 5010, Airport Master Record, particularly data elements associated with Gross Weight (Data Elements 35 through 38) and Pavement Classification Number (Data Element 39). Requires all public-use paved runways serving aircraft with gross weights equal to or greater than 25,000 pounds at NPIAS airports to have gross weight and PCN data based on this guidance within 3 years of the signature date of this AC.

Contains standards for the siting and installation of signs on airport runways and taxiways. Incorporates mandatory hold signs that reflect changed standards for the Precision Obstacle Free Zone (POFZ) and Category (CAT II/III) operations. Includes sign standards to assist airport operators in designating (1) the POFZ holding position in those instances where a taxiway, holding apron, or other movement area would result in an aircraft fuselage or tail penetrating, and (2) the alternative holding position on a taxiway during CAT II/III operations necessary to maintain adequate aircraft separation.
