Taxiway Identification and Sign & Marking Plan Development and Implementation Best Practices Joseph R. Shell, C.M. Delta Airport Consultants, Inc.
Key Components of an Effective Taxiway Identification and Sign & Marking Plan • Correctness of existing information • Your plan is only as good as the information you gather • Adherence of planned development to advisory circulars • Develop a culture of verification • Consistency and clarity of plan drafting • If it can not be read - it can not be reviewed
Correctness of Existing Information • Use recent aerial photo & planimetrics • Obtain recent photo of each sign • Note differing types of pavement • Note condition of existing markings and signs
AC 150/5340-1K, Change 1 Standards for Airport Markings • -Runway Threshold Markings 20 feet from Runway Threshold • -Runway Center Line Marking constraints • -Holding Position Markings extend beyond Edge Stripe • -Holding Position Markings on shoulder - ADGs V and VI • -Center Surface Painted Marking - ADGs I and II Adherence of planned development to advisory circulars

AC 150/5340-18F, Standards for Airport Sign Systems • -Vehicle roadway/runway holding position sign (still not finalized by the FAA) • AC 150/5345-44J, Specifications for Runway and Taxiway Signs • -Contains the characteristics for lighted and unlighted signs Adherence of planned development to advisory circulars
Create a single digital file to avoid errors • Complete plan in color to match filed conditions • Use hatch on all pavements • Create dynamic blocks/library of parts • Design for multiple uses Consistency & Clarity of Plan Drafting
