Standards for Airport Markings Draft AC 150/5340-1M ...

1 Federal Aviation Administration Standards for Airport Markings Draft AC 150/5340-1M . Principal Changes Presented to: ACC Airports Technical Workshop By: Airport Engineering Division, AAS-100. Date: June 2017. Primary Principal Changes Topic 1 - Prohibition for Preformed Thermoplastics Surface Markings on Runways Topic 2 Change in Holding Position marking for Runway Approach-Departure Areas Pattern B replaces Pattern A. Mitigation of taxiing airplanes under landing/departing airplanes Reductions to ATCT and pilot workloads Federal Aviation 2. Administration Topic 3 Criteria for No-Taxi Island Usage New Dedicated Paragraph with four most common Case Illustrations Focus: Reinforce FAA runway safety initiatives and taxiway design Standards per AC 150/5340-1 and AC 150/5300-13. Taxiway Excursions Runway Incursions Federal Aviation 3. Administration Topic 1 - Prohibition Preformed Thermoplastic Markings have been limited to taxiway applications.

2 However . Intermittent inquiries persist for runway applications Solution? New Safety Alert Box Added FAA Technical Report DOT/FAA/AR-TN08/22, Evaluation of Thermoplastic marking Materials (May 2008) reports: not to be used on runways because of the significantly lower friction readings recorded as compared to dry pavement . Federal Aviation 4. Administration Paragraph Safety Alert Reduced Runway Surface Friction Prohibition of Preformed Thermoplastic Surface Markings on Runways Until further notice, preformed thermoplastic surface Markings are not to be used on runways because of the significantly lower friction readings recorded on such Markings as compared to dry pavement (see FAA Technical Report DOT/FAA/AR-TN08/22, Evaluation of Thermoplastic marking Materials). Federal Aviation 5. Administration Topic 2 New marking Criterion Holding Position marking for Runway Approach-Departure Areas Pattern B replaces Pattern A.

Federal Aviation 6. Administration Topic 3: No-Taxi Island New Paragraph assembles information into one primary paragraph. Reinforces: Safety enhancements along taxi routes Specified taxiway design Standards per AC 150/5300- 13A. Focus - Mitigation of: Taxiway Excursions Runway Incursions, and, to some degree Wrong Runway Takeoffs Federal Aviation 7. Administration New Design Criterion - Width of green areas for No-Taxi Islands equals the width of the std taxiway shoulder for the Taxiway Design Group (TDG). Paragraph describes 4 cases - most common taxiing situations - supported by figures for visual clarification: Exiting Aprons Taxiing between aprons and entrance taxiways Entering Runways Provides sequential practices to mitigate excursions from paved taxiways and to mitigate runway incursions Federal Aviation 8.

4 Administration Sequential Process: Apron Case First, reconfigure taxiway route(s) located on the apron to create a no- taxi island in front of the exiting taxiway serving the runway. Objective: Produce multi-turning operations for pilots. Second, after identifying the location of the No-Taxi Island(s), paint dual-continuous taxiway edge Markings . If runway incursions continue, then paint yellow taxiway shoulder Markings . If runway incursions persist, then apply a green border starting from the end of yellow taxiway shoulder Markings to create a visually green . no-taxi island(s). Depth of the green border equals the width of standard taxiway shoulder for the largest taxiway design group using this taxiway. Green borders are per Federal Standard 595, Color Number #34110. Third, install vertical taxiway signage in accordance with AC 150/5340- 18. Lastly, paint any other required or other deemed necessary surface Markings per the marking advisory circular.
