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 circularsDevelop a culture of verification

• Consistency and clarity of plan draftingIf 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

Adherence of planned development to advisory circulars

• 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

Consistency & Clarity of Plan Drafting

• 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
