Section 3. Naming of NAVAIDs, Aeronautical
Facilities, and Fixes
3-3-1. GENERAL
a. All fixes located at a common point shall have
the same name/code regardless of type, altitude, or
route structure.
b. If one of the collocated fixes is a NAVAID, the
other fixes shall be assigned the same name and
three-letter identifier.
3-3-2. RESPONSIBILITY
a. Service area office are responsible for assigning
and changing names of NAVAID and aeronautical
facilities, and shall follow the instructions contained
herein and in FAAO JO 7350.8, Location Identifiers,
Chapter 1.
b. AIM is responsible for issuing five-letter
names for radio fixes, waypoints, marker beacons,
and compass locators. Five-letter names shall be
issued by AIM to the National Flight Procedures
Office, Major Military Commands (MAJCOM) and
Air Route Traffic Control Centers (ARTCC) for
future assignments.
c. AIM in conjunction with the respective service
area office, shall ensure that no duplication in
location name exists.
3-3-3. NAMING OF NAVAIDs
a. The NAVAID name selected should represent a
city, town, or prominent geographic landmark that is
depicted on a sectional aeronautical chart at or near
the site. If one is neither available nor suitable, a local
memorial name may be used. A common, easily
understood word should be selected for the NAVAID
name.
b. The name shall not sound similar to an existing
NAVAID/fix location name within the originating
ARTCC's area, the adjacent ARTCC's area, or within
a 300 NM radius from the NAVAID involved.
c. Unduly long names should not be used.
d. A navigational aid with the same name as the
associated airport should be located on that airport.
However, in existing situations, a NAVAID off the
airport with the same name as the airport may retain
the airport name provided there is no other NAVAID
with the same name. If retention of the airport name
at an off-airport NAVAID could lead to a potentially
confusing situation, the name should be changed.
Only one NAVAID located on the airport may be
assigned the airport name.
NOTE-
For the purpose of this paragraph only, a compass locator
shall be considered as a separate NAVAID.
e. Instrument Landing Systems (ILS).
1. Inner/middle fan markers (without collocated
nondirectional radio beacons (NDBs) or compass
locators) and localizer equipment are not normally
assigned names. Localizers are identified with the
associated airport name and applicable runway
number in official writings.
2. All outer markers shall be assigned names/codes. If the outer marker is to be situated at the same
geographic location as a fix, it shall adopt the fix
names/code.
3. All outer compass locators (LOM) and
middle compass locators (LMM) shall be assigned
names/codes. If co-located with a fix, they shall also
adopt the fix name/code.
f. Names/codes assigned shall be the "chart
names" that will appear on aeronautical charts, in
airspace dockets, and other official publications and
records.
3-3-4. NAMING OF WAYPOINTS,
INTERSECTIONS, AND DME FIXES
a. To decide whether a fix needs to be named, see
Order 8260.19, Flight Procedures and Airspace.
b. Names assigned for waypoints, intersections,
Air Traffic Control (ATC) coordination, and Distance
Measuring Equipment (DME) fixes not co-located
with a navigational aid shall consist of a single
five-letter pronounceable name. These five letters
shall serve as the name, identifier, and computer
code.
c. Regional/service area office requests for
specific five-letter names for radio fixes and
waypoints should be avoided, but may be granted by
AIM if feasible.
d. Five-letter names that are assigned by National
Flight Procedures Office and major commands will
be coordinated with the associated ARTCC to
preclude similar sounding fix names.
e. AIM shall not duplicate any radio fix, waypoint,
marker beacons or compass locators names.
f. A fix or waypoint name change is required if the
fix/waypoint is moved 5 nautical miles (NM) or more
unless operational requirements dictate otherwise.
