NOTE-
The above procedures do not preclude a specialist from
exercising his/her own judgment in providing further
assistance when there is the slightest doubt about the
adequacy of data being furnished to alert a pilot to the
existence of an MTR or MOA.
6-5-2. AERIAL REFUELING TRACKS
Upon notification from the ARTCC or a scheduling
facility that a published refueling track will be
activated and all or part of the activity will take place
outside of restricted/warning areas or Class A
airspace, the tie-in AFSS/FSS shall issue a NOTAM
for the aerial refueling track.
6-5-3. SPECIAL MILITARY FLIGHTS
a. Advise the ARTCC of flight notification
messages, progress reports, changes en route, and
related messages concerning Presidential or Vice
Presidential flights.

dures if arrival is not received within 15 minutes after
ETA and immediately notify ANRCC (Alaskan
NORAD Region Control Center).
6-5-4. MILITARY FOREIGN FLIGHTS
Generally, all military foreign flights are required to
clear through specified military bases. Pilots
normally will not file flight plans directly with an
AFSS/FSS unless BASOPS is not available.
BASOPS with no Service B access will forward an
ICAO-type flight plan message via their tie-in
AFSS/FSS for relay through the AFTN. BASOPS
should specify all addressees, both ATC and
operational, in accordance with ICAO standards and
military regulations.
6-5-5. USAF/USN UNDERGRADUATE
PILOTS
To identify aircraft piloted by solo USAF/USN
undergraduate student pilots (who may occasionally
request revised clearances because they normally are
restricted to flight in VFR conditions), the aircraft
identification in the flight plan shall include the letter
Z as a suffix. Do not use this suffix in ground-to-air
communication.
NOTE-
USAF solo students who have passed an instrument
certification check may penetrate cloud layers in climb or
descent only. Requests for revised clearances to avoid
clouds in level flight can still be expected. This does not
change the requirement to use the letter Z as a suffix to the
aircraft identification.
6-5-6. MESSAGE HANDLING
Accept and forward messages from any military
authority that concern aircraft movement, national
defense, safety of flight, or emergencies. This
includes, but is not limited to, the following:
a. Flight Advisory Messages.
1. The tie-in AFSS/FSS originating the adviso-
ry or receiving it from the originating BASOPS shall
determine the AFSS/FSS nearest the aircraft's
estimated position for VFR flights, or the appropriate
ARTCC for IFR flights. Transmit a numbered
message only to the facility identified. Include in the
text, FLT ADVY, aircraft identification and type, and
route of flight in that order. The last item shall be the
identifier of the originating BASOPS or AFSS/FSS.

6-7-1 Law Enforcement Messages
Section 7. Law Enforcement Messages
6-7-1. LAW ENFORCEMENT ALERT
MESSAGES (LEAM)
The El Paso Intelligence Center (EPIC ) is an
organization composed of 14 Federal agencies,
including the FAA. The principal mission of EPIC is
to facilitate the exchange of information and tactical
intelligence on illicit narcotic trafficking and to
support, through the intelligence process, Federal
investigations concerning violation of Federal
statutes as they apply to narcotics, aliens, currency,
and weapons. EPIC issues two types of Law
Enforcement Alert Messages (LEAM) that pertain to
aircraft: Aircraft Lookout Alerts and Stolen Aircraft
Alerts. Upon receipt of a LEAM from EPIC, take the
following actions:
a. Aircraft Lookout Alerts.
1. Keep active for 7 days, unless otherwise
specified, or until cancellation is received.
2. Do not disseminate Suspect Aircraft Look-
outs outside of official government facilities. As this
data is inherently sensitive, unauthorized disclosure
of information could compromise an investigation,
endanger lives, and could result in crim inal
prosecution or administrative action against the
offender.
REFERENCE-
FAAO 1600.29, Para 7c(7), Stolen Aircraft Alert Procedure.
NOTE-
Paragraph 6-7-1a applies only to FSS and AFSS
facilities in Alaska. AFSS facilities operating under
contract of a Service Provider are not considered official
government facilities and therefore will not receive
Aircraft Lookout Alerts.
b. Stolen Aircraft Alerts. Stolen Aircraft Alerts
request recipients to watch for and report on the
location and movement of an aircraft which has been
reported stolen.
1. M1FC.
(a) Keep active until included in a stolen
aircraft summary or until cancelled.
(b) Upon receipt, check local records for any
aircraft contact, beginning with the date the aircraft
was reported stolen. AFSSs shall notify their Flight
Service Data Processing System (FSDPS) personnel
to run the ENFORCE program as soon as practicable.
(c) Relay any information available to the
office listed on the alert.
2. OASIS. When OASIS receives a correctly
formatted stolen aircraft alert, it processes it as
follows: Checks the database for the past 15 days for
a match. If no match is found, the LEAM is added to
the Law Enforcement (LE) List with a green icon and
no alarm. If a match is found, a Law Enforcement
alarm is generated at designated workstations and the
LEAM is placed on the LE List with a red icon.
c. Stolen Aircraft Summaries.
1. Stolen Aircraft Summaries should be used to
displace and consolidate all the individual stolen
aircraft alerts received in the interim.
2. Monthly summaries are sent as soon as
possible after the end of the month. They include
aircraft registration numbers, aircraft type, and the
date/time stolen and/or recovered.
3. Biannual summaries are sent in January and
July. They list only those aircraft stolen in the past
2_years.
d. All LEAM.
1. Distribute the Stolen Aircraft Alerts and
Summaries, at the discretion of the Air Traffic
Manager, to all parties, fixed base operators, airport
managers, etc.
REFERENCE-
FAAO 1600.29, Para 7c(6), Stolen Aircraft Alert Procedure.
2. Check local records for the previous 24 hours.

cancellation or a summary if the latter does not
include this aircraft's registration number.
6-7-2. INITIATING LEAMs
Any inquiries from airport managers, aircraft owners,
or law enforcement entities to initiate an alert
message shall be directed to EPIC. EPIC is interfaced
with the National Crime Information Center, which
gives them access to any stolen aircraft report entered
by law enforcement agencies. FAA facilities shall not
volunteer to relay this inform ation to EPIC .
Assistance shall be limited to providing EPIC phone
number(s) as specified in subpara 6-7-1d3 or
advising the inquiring party to go through normal law
enforcement channels.

a. Title 14 of the U.S. Code of Federal Regulations
(14 CFR) and the International Civil Aviation
Organization (ICAO) require flight plans for all civil
aircraft operation between the United States and
foreign locations. Bureau of Customs and Border
Protection requirements, international flight plan
information, and Air Defense Identification Zone
(ADIZ) penetration requirements are listed in other
publications; e.g., the FAA International Flight
Information Manual (IFIM), the Bureau of Customs
and Border Protection Guide for Private Flyers, the
Aeronautical Information Manual (AIM), 14 CFR
Part 91, and 14 CFR Part 99. Designated airports of
first landing are listed in the IFIM and the
Airport/Facility Directory (A/FD).
b. This chapter provides guidance to AIFSS,
AFSS, FSS, and ARTCC facilities that transmit
international flight movement messages. It incorpo-
rates relevant information from ICAO and 14 CFR
docum ents. All personnel required to handle
international messages shall be familiar with ICAO
documents containing instructions for preparing and
transmitting communications for the AFTN circuits.
These documents should be retained at FAA facilities
which handle international messages. FAA personnel
shall not act as agents for any aircraft operating or
dispatching company.
NOTE-
International telecommunications instructions are found
in International Standards and Recommended Practices,
ICAO Annex 10 - Aeronautical Telecommunications,
Volume II, and Document 7946, Manual of Teletypewriter
Operating Practices. DOC 4444-RAC 501, Rule of the
Air and Air Traffic Services, lists various ATS movement
messages. Location indicators are contained in ICAO
Document 7910, and Designators for Aircraft Operating
Agencies Aeronautical Authorities and Services are
contained in ICAO DOC 8585. FAA policies concerning
acceptance of messages for international transmission
are contained in 14 CFR Part 189.
c. AFSSs and FSSs that transmit only occasional
international messages or are unable to determine the
correct addressing for all air traffic units concerned
may refer the pilot to the proper gateway facility or
address the message to the proper gateway facility for
handling. The gateway stations and their areas of
responsibilities are as follows:
1. New York AIFSS (ISP): Bermuda, Canada,
North Atlantic, Europe, and Africa.
2. Miami AIFSS (MIA): Caribbean, South

SVC. ZKC121 QTA RPT
FF KZKCZQZX
031840 KSLCYTYX
SVC. ZKC122 QTA MSR
b. Assign the appropriate priority indicator to
international service messages. When service
messages refer to messages previously transmitted,
assign the same priority prefix. Identify a service
message by inserting SVC as the first item of the text.
EXAMPLE-
FF TJSJYFYX
DTG KSEAYFYX
SVC. RUMES 231015
(Text)
7-1-5. TRANSMISSION VIA NADIN
International messages are generally introduced on
NADIN for relay to AFTN circuits.
a. M1FC facilities use the ICAO flight plan mask
or TB mask. Addressee(s): Not to exceed 69
characters or seven addressees, each addressee
separated by a space.
b. AISR facilities handle international messages
on NADIN for relay to AFTN as follows:
1. Start of message. New Line Key.
2. Preamble (priority, space, addressee(s).
(a) Priority. Two-character precedence field.
(b) Addressee(s). Not to exceed 69 characters
or seven addressees, each addressee separated by a
space.
(c) End of Line (EOL) new line key.
(d) End of Text (EOT) (enter function).
c. OASIS facilities use the ICAO Flight Plan
dialog box or General Facility Message. A maximum
of 16_addressees can be entered.
7-1-6. TRANSMISSION OF ATS
MESSAGES
a. Air traffic service messages are interchanged in
the international air traffic control system in the
following modes:
JO 7110.10T 2/14/08
7-1-3 Messages and Formats
1. The preferred step-by-step mode wherein
each ACC/ARTCC sends forward the full current
(updated) flight plan information as the flight
progresses.
2. The simultaneous mode wherein information
extracted from the filed flight plan (FPL) is sent
simultaneously to all ATS units along the route of
flight. In this mode, only amendments to the FPL,
plus necessary control information, are forwarded
from center to center as the flight progresses.
b. Prepare and transmit ATS messages as set forth
in this Order. Address these messages as follows:
1. Include an eight-character addressee indica-
tor for each addressee. For M1FC and AIS R
facilities, there can be no more than one line
(69_characters including separating spaces) of
addressees. When more than the allowable number of
addressees are required, two or more transmissions of
the message (each with no more than the allowable
number of addresses) must be made. For OASIS
facilities, a maximum of 16 addressees can be
entered. The eight-letter combination addressee
indicators are composed as follows:
(a) The four-letter ICAO location indicator;
e.g., MPTO. Use only those listed in ICAO DOC
7910 (Location Indicators). Some ICAO eight-char-
acter addressees for Mexico and Canada are listed in
FAAO JO 7350.8, Location Identifiers.
(b) A four-letter designator for the facility
type/office, or if no designator has been assigned,
affix YXYX for military, ZZZX for aircraft in flight,
or YYYX for all other cases; e.g., MTPPYYYX. (See
Note.)
REFERENCE-
ICAO DOC 8585, Designators for Aircraft Operating Agencies,
Aeronautical Authorities and Services.
NOTE-
The most frequently used and authorized designators are:
YAYX Government Civil Aviation Authority (FAA
Regional Office or Headquarters).
YCYX Rescue Coordination Center (RCC).
YDYX Authority Supervising the Aerodrome.
YFYX Aeronautical Fixed Station (AFSS/FSS/IFSS/
IATSC).
YMYX Meteorological Office (NWS).
YNYX International NOTAM Office (NOF).
YTYX Telecommunications Authority.
YWYX Military Flight Operational Control Center
(ACP)
YXYX Military Organization (BASOPS).
YYYX Organization not allocated a two-letter
designator.
ZOZX Oceanic Air Traffic Control Center.
ZPZX Air Traffic Service Reporting Office.
ZQZX Computer Facility at ACC/ARTCC.
ZRZX ACC/ARTCC. (Center in charge of a FIR/UIR
when the message is relevant to a VFR flight (AMIS)).
ZTZX Aerodrome Control Tower.
ZZZX Aircraft in flight.
(c) A one-letter designator will appear
following an air carrier designator to indicate the
department or division of the organization addressed.
2. Filing time. A six-digit date/time group
indicating the time the message is filed with the
AIFSS/AFSS/FSS for transmission.
c. Originator Indicator. Consists of an eight-letter
sequence similar to an address indicator, identifying
the place of origin and the organization originating
the message.
d. Supplementary Address and Origin Informa-
tion. When the four-letter designators YXYX,
ZZZX, or YYYX are used, identify the aircraft
operator or organization at the beginning of the text
preceding the start-of-ATS data symbol ( - - ), in
the same order as in the addressee(s) and/or originator
indicator(s). Where there is more than one such
insertion, the last should be followed by the word
“stop.” Where there are one or more insertions in
respect to addressee indicators plus an insertion in
respect to the originator indicator, the word FROM is
to appear before that relating to the originator.
e. When addressing flight plan messages or
related amendments and flight plan cancellation
messages to centers, use one of the four-letter
designators as follows:
1. If message is relevant to IFR and:
(a) The ARTCC is computer-equipped
(U.S. ARTCCs), use ZQZX.
(b) The center is not computer-equipped, use
ZRZX.
(c) R elevant to oceanic operations, use
ZOZX.
NOTE-
Some centers may request specific addressing different
from above. ZTZX and ZPZX are used internationally, but
are not used in internal U.S. application.
2. If message is VFR (AMIS), use ZRZX.
3. If SVC or administrative, use ZRZX.

7-1-7. ORIGINATING MESSAGES
a. Messages for ATS purposes may be originated
with ATS units by aircraft in flight, or, through local
arrangem ents, a pilot, the operator, or their
designated representative.
b. Accept air-filed flight plans or changes in
destination information from aircraft inbound from
foreign locations and, if requested by the pilot, enter
Customs notification service.
c. Do not accept round-robin flight plans to
international locations, other than Canada.
NOTE1. Only accept VFR round-robin flight plans to Canada
if the filer of the flight plan is in possession of a valid
numbered letter of authorization and adheres to the
provisions contained therein.
2. Individual requests for the temporary authorization
letter should be directed to the appropriate service area
office.
3. The temporary authorization letter mandates the pilot,
or responsible party, to provide the AFSS/FSS with a
name, telephone number and authorization number for
inclusion in the remarks section of the flight plan.
4. AFSS/FSS shall log a double (2) count for the
round-robin flight plan.
d. Do not accept assumed departure flight plans
when the destination is in a foreign country other than
Canada.
e. Aircraft movement, control, and flight informa-
tion messages for purposes other than ATS, such as
operational control, shall be originated by the pilot,
the operator, or their designated representative.
7-1-8. ADDRESSING MESSAGES
a. Addressing the flight plan is determined by the
point of departure, the destination, and the FIR
boundaries to be penetrated during the course of the
flight.
b. Address IFR FPL messages to the ARTCC
serving the airport of departure and to all ATS units
(including oceanic) providing air traffic control
service or concerned with flight along part or the
whole of the route to be flown except FAA ATCTs
and other conterminous U.S. ARTCCs.
NOTE-
Within the North Atlantic (NAT) Region, FPLs on turbojet
aircraft transiting the control areas of Gander Oceanic,
New York Oceanic, Reykjavik, Santa Maria Oceanic,
Shanwick Oceanic and Sondrestrom (south of 70 degrees)
within 90 nautical miles of the control area boundary,
shall be addressed to the adjacent ACC to provide lateral
separation. For all other aircraft, a 120 nautical mile
proximity limit shall apply.
c. Transmit all IFR FPLs to ARTCCs not less than
1 hour prior to the proposed departure time. Do not
hold FPLs until after departure time and transmit as
a combined FPL and DEP. Separate FPL and DEP
messages must be transmitted.
NOTE-
ICAO flight plans do not require an acknowledgment to
the transmitting facility.
d. Address aircraft movement messages only to
those ATS units responsible for the provision of
relevant service, except when requested by the
operator concerned, these messages, when
transmitted via the AFTN, may also be routed, as
specified by the operator or a representative to:
1. One addressee at the point of intended
landing or point of departure.
2. Not more than two operational control units
concerned.
e. The ARTCC serving the departure airport shall
transmit the DEP message on IFR aircraft to all
known recipients of the FPL message. Flights
between conterminous U.S. and Canada (excluding
Gander Oceanic), Alaska, Hawaii and Puerto Rico do
not require DEP messages. Discontinuance of DEP
messages affecting the route of flight can only be
accomplished by ICAO Regional Air Navigation
Agreement.
7-1-9. FLIGHT PLAN FORMS AND
INSTRUCTIONS
a. Use the International Flight Plan, FAA Form
7233-4 (see Appendix A), ICAO Model Flight Plan
Form displayed in DOC 4444, M1FC ICAO Flight
Plan Mask, or OASIS ICAO Flight Plan dialog box
and apply the procedures set forth in this section for
flight:
NOTE-
Exceptions apply for flights to Canada and Mexico, see
Section 4 and Section 5, for procedures.
1. Originating within conterminous U.S. and
Canada and destined nonstop to points beyond those
areas.
JO 7110.10T 2/14/08
7-1-5 Messages and Formats
2. Originating within or transiting Pacific Flight
Information Regions (FIR) and destined to or from
FIRs beyond the Pacific Region including the North
American (NAM) Region.
NOTE1. The NAM Region encompasses the conterminous U.S.,
Alaska, and Canada to the North Pole.
2. FAA Form 7233-1, or Military Form DD-175, and
domestic procedures are used for flights in the
conterminous U.S., Canada, and the Honolulu, Alaskan,
and San Juan domestic control areas.
3. AISR facilities record on the flight plan form
the time that a flight plan is filed. This time will
constitute evidence of the pilot's intention to comply
with Customs, Immigration, and Public Health
requirements and will be made available upon request
from these authorities.
7-1-10. ICAO ATS MESSAGE FORMAT
The following are examples of ICAO message types
most likely to appear on AFTN/NADIN circuits. The
number above the data corresponds to the field type
numbers on the flight plan form (FAA Form 7233-4)
and on the chart of Standard ATS Messages and Their
Composition, Appendix A.
a. Departure Message (DEP). ARTCCs are the
designated ATS unit responsible for originating and
transmitting DEP messages on all IFR aircraft
departing airports within their center boundaries. IFR
flight plans must be transmitted to ARTCCs at least
1 hour before departure. This allows ARTCCs to
determine recipients of DEP message when domestic
portions are transmitted to ARTCCs in M1 format.
Do not hold FPLs and combine with DEP into a
single message.
b. Delay Message (DLA). Transmitted when
departure of an aircraft, for which an FPL message
has been transmitted, is postponed or delayed more
than 30 minutes after the estimated time of departure
contained in the FPL.
c. Alerting Message (ALR). Relating to an
overdue situation on an aircraft.
d. Supplementary Flight Plan (SPL) information
shall be sent to ATS units requesting the information
(RQS). |
