Contains the Federal Aviation Administration 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.
Standards for Airport Sign Systems
Incorporates new mandatory hold signs that reflect changed standards for the Precision Obstacle Free Zone (POFZ) and Category (CAT II/III ) operations. These changes correspond to revisions to AC 150/5300-13, Airport Design, that change the Precision Object Free Area (POFA) to the POFZ and incorporate new separation standards for taxiways that parallel runways used for certain low visibility operations. This AC cancels AC 150/5340-18C, Standards for Airport Sign Systems, dated July 31, 1991.
