EXPLANATION OF CHANGES.
incorporates guidance on use of the enhanced
taxiway centerline markings and the surface
holding position signs.
These enhancements were

The enhanced taxiway centerline is being adopted
as the standard for commercial service airports that
have 1.5 million or more passenger enplanements
in a calendar year.
The enhanced taxiway
centerline will be the only acceptable means of
complying with 14 CFR Part 139 for these airports
effective June 30, 2008.
Similarly, the extension of
the runway holding position markings onto the
paved shoulder is being adopted as the only
acceptable means of compliance with Part 139 for
airports regularly served by aircraft in Aircraft
Design Groups 5 and 6, also effective June 30,
2008. The standards for enhanced taxiway
centerline and extension of the runway holding
position markings are optional for all other airports.
To promote an orderly

metric conversions are based on operational
significance and may not be exact equivalents.
conversion procedure used throughout the AC
applies the relationship of 1 foot equals 0.3 meter,
except for a few instances where rounding was
used in order for linear dimensions to sum
correctly. Until there is an official changeover to
the metric system, the English dimensions should
The FAA recommends the
