Arrival Procedures

aircraft is equipped with the required NAVAID(s) in
order to execute the approach, including the missed


Some military (i.e., U.S. Air Force and U.S. Navy)
IAPs have these “additional equipment required”
notes charted only in the planview of the approach
procedure and do not conform to the same application
standards used by the FAA.


The FAA has initiated a program to

provide a new notation for LOC approaches when
charted on an ILS approach requiring other
navigational aids to fly the final approach course. The
LOC minimums will be annotated with the NAVAID
required (e.g., “DME Required” or “RADAR
Required”). During the transition period, ILS
approaches will still exist without the annotation.


Many ILS approaches having minima

based on RVR are eligible for a landing minimum of
RVR 1800. Some of these approaches are to runways
that have touchdown zone and centerline lights. For
many runways that do not have touchdown and
centerline lights, it is still possible to allow a landing
minimum of RVR 1800. For these runways, the
normal ILS minimum of RVR 2400 can be annotated
with a single or double asterisk or the dagger symbol


 for example “** 696/24 200 (200/1/2).” A note

is included on the chart stating “**RVR 1800
authorized with use of FD or AP or HUD to DA.” The
pilot must use the flight director, or autopilot with an
approved approach coupler, or head up display to
decision altitude or to the initiation of a missed
approach. In the interest of safety, single pilot
operators should not fly approaches to 1800 RVR
minimums on runways without touchdown and
centerline lights using only a flight director, unless
accompanied by the use of an autopilot with an
approach coupler.


The naming of multiple approaches of the

same type to the same runway is also changing.
Multiple approaches with the same guidance will be
annotated with an alphabetical suffix beginning at the
end of the alphabet and working backwards for
subsequent procedures (e.g., ILS Z RWY 28, ILS Y
RWY 28, etc.). The existing annotations such as
ILS 2 RWY 28 or Silver ILS RWY 28 will be phased
out and replaced with the new designation. The Cat II
and Cat III designations are used to differentiate

between multiple ILSs to the same runway unless
there are multiples of the same type.


RNAV (GPS) approaches to LNAV, LP,

LNAV/VNAV and LPV lines of minima using WAAS
and RNAV (GPS) approaches to LNAV and
LNAV/VNAV lines of minima using GPS are charted
as RNAV (GPS) RWY (Number) (e.g., RNAV (GPS)
RWY 21). VOR/DME RNAV approaches will
continue to be identified as VOR/DME RNAV RWY
(Number) (e.g., VOR/DME RNAV RWY 21).
VOR/DME RNAV procedures which can be flown by
GPS will be annotated with “or GPS” (e.g., VOR/



Based Navigation (PBN)

Box. As charts are updated, a procedure’s PBN
requirements and conventional equipment require-
ments will be prominently displayed in separate,
standardized notes boxes.  For procedures with PBN
elements, the PBN box will contain the procedure’s
navigation specification(s); and, if required: specific
sensors or infrastructure needed for the navigation
solution, any additional or advanced functional
requirements, the minimum Required Navigation
Performance (RNP) value, and any amplifying
remarks. Items listed in this PBN box are
REQUIRED for the procedure’s PBN elements. For
example, an ILS with an RNAV missed approach
would require a specific capability to fly the missed
approach portion of the procedure. That required
capability will be listed in the PBN box. The separate
Equipment Requirements box will list ground


equipment requirements. On procedures with both
PBN elements and equipment requirements, the PBN
requirements box will be listed first. The publication
of these notes will continue incrementally until all
charts have been amended to comply with the new


Approach minimums are based on the local

altimeter setting for that airport, unless annotated
otherwise; e.g., Oklahoma City/Will Rogers World
approaches are based on having a Will Rogers World
altimeter setting. When a different altimeter source is
required, or more than one source is authorized, it will
be annotated on the approach chart; e.g., use Sidney
altimeter setting, if not received, use Scottsbluff
altimeter setting. Approach minimums may be raised
when a nonlocal altimeter source is authorized. When
more than one altimeter source is authorized, and the
minima are different, they will be shown by separate
lines in the approach minima box or a note; e.g., use
