indicator). An element is separated from another
element by a period character.
(b) When consecutive fix elements or route
elements are filed, the fixed sequence format is
maintained by inserting two period characters
between the filed Field 10/RT: elements; e.g., fix..fix
or airway..airway.
(c) When a pilot files an airway..airway combination,
obtain the point of transition and insert it in
the transmitted flight plan; e.g., SGF.J105..J24.
STL.J24. The foregoing does not apply if the first
encountered fix happens to be the next filed junction
point within the route.
NOTEOASIS.
Airway..airway combinations in the route of
flight require a defined junction (either five-character
alphanumeric, LOCID, or pre-defined fix-radial-distance.)
(d) The slash character (/) is used to file a
latitude/longitude fix or in describing an ETE.
(e) The maximum number of filed field
elements for computer-addressed flight plans is 40.
Double period insertions do not count against the
40-element limitation. Transmit flight plans filed
exceeding the route element limitation to the
ARTCC, not its computer.
(f) Fix Descriptions. A fix must be filed in
one of the following ways:
(1) Fix Name. Domestic, Canadian, and
International identifiers of two-to-five alphanumeric
characters.
(2) Fix Radial Distance (FRD). Consists of
eight-to-eleven alphanumeric characters in the
following sequence: Two-to-five characters identifying
a navigational aid, three characters of azimuth
expressed in degrees magnetic, and three characters
of distance expressed in nautical miles from the
navigational aid. Zeros preceding a significant
character shall be entered before the azimuth and
distance components as required to assure the
transmission of three characters for each.
(3) Latitude/Longitude. Consists of nineto-
twelve characters entered as follows: The latitude
shall appear as the first component as four numbers
(trailing zeros required) with an optional letter N or
S appended. If the optional letter is omitted, north is
understood. Latitude shall be separated from
longitude with a slash (/) element separator.
Longitude shall appear as the second component as
four or five digits (trailing zeros required, leading
zero optional) with an optional letter W or E
appended. If the optional letter is omitted, west is
understood.

(4) Navigation Reference System (NRS)
Waypoints. NRS waypoints consist of five alphanumeric
characters, which include the ICAO Flight
Information Region (FIR) identifier, followed by the
letter corresponding to the FIR subset (ARTCC area
for the contiguous U.S.), the latitude increment in
single digit or group form, and the longitude
increment.

“KD34U”
(g) Route Descriptions. A route must be filed
in one of the following ways:
(1) Airway. The official airway designator
must be filed.
(2) Coded Routes. Coded routes are a
shorthand method of describing a route segment or
segments which may have an altitude profile
described, an adapted airspeed within the route,
reentry or loop routes as an option, or a time delay at
a fix within the route as an option. Some of the
principal uses of coded routes are as follows:
[a] Instrument Departures (DP). DP, if
used, must be filed by the computer code designator
as the second element of Field 10/RT and followed by
the transition or exit fix.
[b] Standard Terminal Arrivals (STAR).
STAR, if used, must be filed by the computer code
designator as the next to last element of Field 10/RT:
and be immediately preceded by the entry or
transition fix.
[c] Published Radials. Published radials
(e.g., within a preferred route) are considered
airways. Do not file unpublished radials.
EXAMPLE-
.JFK053..DPK017
.RBV020
[d] Military Routes. Certain military
routes (e.g., Military Training Routes (MTR) and Air
Refueling Tracks/Anchors), are considered coded
routes. The route designator must be preceded and
followed by the entry and exit fixes in terms of
fix/radial/distance (FRD), and reentry information
may be suffixed to certain military coded routes as
follows:
[1] The entry and exit fix must be
associated with a fix on the route, and the entry fix
must be prior to the exit fix on the route.

PKE107012
[2] Routes having reentries for a single
Strategic Training Range (STR) site shall contain the
entry of alternate entry fix in terms of FRD, the route
