Standards for Airport

Markings

Draft AC 150/5340-1M

Principal Changes

ACC Airports Technical Workshop

Airport Engineering Division, AAS-100

June 2017

2Federal AviationAdministration

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


• Topic 3 – Criteria for No-Taxi Island

Usage

– New Dedicated Paragraph 1.5 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


Topic 1 - Prohibition

• Preformed Thermoplastic markings have been

limited to taxiway applications. 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”


Paragraph 1.3.2

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).


Topic 2 – New Marking Criterion Holding Position

Marking for Runway Approach-Departure Areas

• Pattern B replaces

Pattern A

– Mitigate taxiing

under landing and

departing aircraft

– Reduce ATCT/Pilot

workloads

– New signage std

accompanies this std

AC 150/5340-18

•Pattern A - Runway Holding Position Marking

•Pattern B – ILS Holding Position Marking


Topic 3: No-Taxi Island

• New Paragraph 1.5 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


• 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


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.
