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
3Federal AviationAdministration
• 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
4Federal AviationAdministration
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”
5Federal AviationAdministration
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
7Federal AviationAdministration
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
8Federal AviationAdministration
• 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
9Federal AviationAdministration
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.
