#  GENERAL 

## General Administrative Information.

## Purpose. 

The Federal NOTAM System (FNS) is a joint system combining civil and
military NOTAM services. NOTAM creation will be in accordance with
international standards including International Civil Aviation
Organization (ICAO) Annex 15, Standards and Recommended Practices and
this order. The NOTAM system should not be used to advertise data
already published or charted.

## Audience. 

All parties who create entries or contribute to the NOTAM system must
comply with this order. This order is distributed to selected offices in
Washington headquarters, service area offices, the William J. Hughes
Technical Center, the Mike Monroney Aeronautical Center, air traffic
field offices and facilities, and airports.

## Where Can I Find This Order?

You can find this order at
https:/employees.faa,gov/tools_resources/orders_notices/

## Cancellation of FAAO 7930.2M.

FAAO 7930.2M is canceled upon publication of this order.

### Explanation of Changes**.**

This change implements ICAO Policy in accordance with the ICAO
Aeronautical Information Services Manuals, Annex 15 and Document 8126.

### Revisions**.**

The contents of this order will be periodically reviewed and updated as
required. Suggestions for revision should be forwarded through the
appropriate facility/service area staff to Aeronautical Information
Management.

## Effective Date.

This order is effective sometime in 2010.

## General NOTAM Information.

### Definition of NOTAM

A NOTAM is a notice distributed by means of telecommunication containing

information concerning the establishment, conditions or change in any

aeronautical facility, service, procedure or hazard, the timely
knowledge of which

is essential to personnel concerned with flight operations.

### Purpose of NOTAM Distribution

The provision of information, which may affect safety, in advance of the
event to

which it relates, and for unserviceabilities that cannot be foreseen.
Thus, to

realize its purpose a NOTAM should be received by the addressee in
sufficient

time for any required action to be taken. The value of a NOTAM lies in
its "news

content" and its residual historical value is therefore minimal.

### Application

This *FAAO 7930.2N, NOTAM handbook* prescribes the procedures to be used

for the determination, origination, preparation and distribution of
NOTAM in

the United States. The procedures are based on the International Civil
Aviation

Organization (ICAO) *Annex 15 to the Convention on International Civil
Aviation*,

*Aeronautical Information Services*.

### United States NOTAM Office (USNOF)

Under the ICAO, each member state shall designate an international NOTAM
office (NOF). The United States NOF is the USNOF.

## UNITS OF MEASUREMENT.

### General.

\- Height is expressed in feet.

\- Altitude is expressed in feet or flight level.

\- Distance is expressed in nautical miles, feet or inches.

\- Weight is expressed in pounds.

\- Temperature is expressed in degrees [Fahrenheit]{.mark}.

Note 1: Whole numbers are to be used unless otherwise indicated in this
manual.

Note 2: Below two nautical miles, distances from aerodromes may be
identified with decimals. Distances below one nautical mile may be
identified in feet or in nautical mile.

### Time System.

The time is expressed in UTC (coordinated universal time) and indicated
to the

nearest minute. The day begins at [0000]{.mark} hours and ends at
[2359]{.mark} hours.

### Date-time Group.

The date-time group is composed of ten figures expressed as YYMMDDHHMM.

The letters YY represent the last two figures of the year; MM represent
the

month; DD the day; HH the hours; and MM the minutes.

Example: 0512251200 for the 25th day of December 2005, 1200 UTC.

### Geographic Reference.

References to aerodromes are expressed in magnetic degrees. Coordinates
are expressed in the ICAO format, in degrees, minutes, and, when
required, seconds. Decimals, in hundredth of a minute instead of seconds
of a degree, if required, are used only when referring to published
information using decimals such as Area Navigation (RNAV), Global
Positioning System (GPS) and Flight Management System (FMS) waypoints.

Example for ICAO format: 644153N 1103633W

Example for ICAO format with decimals: 5250.49N 10827.46W

# NOTAM POLICY, ROLES AND RESPONSIBILITIES

## Policy. 

Authorized personnel who collect and/or disseminate NOTAMs shall be
familiar with the provisions of this order that pertain to their
operational responsibilities. All NOTAM information will be received,
processed, stored, and distributed by the FNS.

## Procedural Application. 

Procedural applications are derived from the Policy promulgated in this
FAA Order (see Chapter 3).

## Avoidance of Duplication. 

Prior to issuing a NOTAM, check all appropriate charts and publications
to ensure the information does not duplicate any published data.

## Roles and Responsibilities. 

All air traffic personnel, regardless of position, shall immediately
report any situation or condition considered hazardous to the operation
of an aircraft to an air traffic facility for appropriate action.
Timeliness of NOTAM information is critical to the safety of flight
operations. Personnel shall coordinate and submit new NOTAM information
within 15 minutes of receipt or discovery for events or outages of 15
minutes or greater (ICAO Annex 10, Volume 1, Attachment D, Paragraph
9.3). Air traffic personnel shall accept and document all aeronautical
information, regardless of source, provided the occurrence is no more
than three (3) days in the future. Information from other than
authorized authorities shall be verified prior to NOTAM issuance.

## NOTAM Authorities. 

NOTAM authorities are offices, units, or personnel who are authorized to
originate a NOTAM. Authorized personnel shall immediately report any
situation or condition considered hazardous to aircraft operations to an
air traffic facility for appropriate action. All NOTAM authorities shall
monitor NOTAMs under their jurisdiction for accuracy and currency.

### Airport Management and Designees. 

Airport management is responsible for observing and reporting airport
conditions. Airport management or designees who have the capability of
direct NOTAM input shall be responsible for classification, accuracy,
format, dissemination, cancellation, and coordination of NOTAM
information describing changes in conditions that affect aircraft
operations at their airport.

Airport management or designees without the capability of direct NOTAM
input shall report conditions to Flight Services. Airport management
shall provide flight service a list of current airport employees who are
authorized to issue NOTAMs.

On joint-use and host-tenant airfields, airport managers shall
collaborate with their military counterparts to establish a letter of
agreement or memorandum of understanding to assure proper NOTAM
authority, responsibility and handling.

### Flight Service Specialists. 

Flight service specialists are responsible for the classification,
accuracy, format, dissemination, cancellation, and coordination of NOTAM
information received from the originating source.

### Technical Operations Services. 

**Aviation System Standards.**

### Flight Standards Service. 

The Flight Procedure Standards Branch, AFS-420, is responsible for
development of policy guidance and procedures for the issuance,
tracking, and cancellation of NOTAMs relating to instrument flight
procedures.

### System Operations Services.

Security Office.

#### Transportation Security Administration (TSA). Any request for a security related NOTAM will be coordinated through the System Operations Security Office. Examples of requests include the TSA Aviation Command Center initiates requests for the establishment of temporary flight restrictions required by hijack situations. These requests are normally made to the service area office; however, these requests may be made directly to air traffic facilities.

#### Secret Service: Temporary Flight Restrictions (TFRs) in the proximity of the President or other parties (14 CFR Section 91.141) will be initiated by Washington headquarters of the U.S. Secret Service through coordination with System Operations Services and System Operations Security. After normal duty hours, the request for issuance of a TFR will be coordinated with the duty officer, Washington Operations Center. The duty officer will contact the designated Military Operations Security representative. In the event the representatives are unavailable, the duty officer will coordinate the NOTAM request with the shift supervisor of the Air Traffic Control System Command Center. 

**Aeronautical Information Management.**

#### Aeronautical Information Management is responsible for ensuring the classification, accuracy, format, dissemination, cancellation, and coordination of NOTAM information for Special Use Airspace (SUA), Global Navigation Satellite Systems (GNSS) and Special Notices such as the Rose Bowl, the Kentucky Derby, the Indianapolis 500 and other events that may cause airspace congestion or significant modifications to ATC procedures. 

#### The National Flight Data Center (NFDC) will review applicable Series H, P, and Z NOTAMs for accuracy, format, completeness, and database agreement. Discrepancies noted by NFDC will be forwarded to the NOTAM originator branch for resolution. NFDC is also responsible for compiling NOTAMs for inclusion in the Notices to Airmen Publication (NTAP).

###  Department of Defense (DOD).

DOD NOTAM authorities are offices, units, or personnel authorized to
originate NOTAMs. They shall monitor all NOTAMs, military and civil,

## Rules for NOTAM

The international standard NOTAM format is contained in Annex 15 (Ref.
\[1\]) to the ICAO Convention. It is the reference format for NOTAMs and
forms the baseline on which this document is developed.

### Format.

The ICAO NOTAM format will be strictly adhered to and the only NOTAM
types allowed are NOTAMN, NOTAMR, and NOTAMC.

### Issuance.

Issue NOTAMs for temporary changes to an aerodrome, airspace, NAS
components, aeronautical charting and publications until the associated
aeronautical charts and related publications are amended, if required.

### Cancellation.

Cancel NOTAMs when associated aeronautical charts or publications are
published. NOTAMs should not remain in the system for more than 90 days
at a given time, except that series P and Z NOTAMs may remain in the
system for up to 224 days to allow time to process procedural
amendments. When conditions warrant a longer period, a replacement NOTAM
should be submitted or a chart publication considered, except for NAVAID
outages that will remain in the NOTAM system until they are returned to
service or are decommissioned.

### Plain Text.

Use of plain text is highly encouraged for NOTAM creation using FNS.
Abbreviations or contractions are unnecessary, cause confusion and
should be avoided. In international communications, NOTAM originators
should be aware that the foreign correspondent may not understand all
contractions and may not have a full command of the English language so
avoid slang phrases and non-approved abbreviations. To decode a
contraction, refer to the Flight Information Handbook, FAAO 7340.1
Contractions or FAAO 7110.65 Air Traffic Control, Pilot/Controller
Glossary.

### NOTAM Address a Single Condition

NOTAM may only address a single condition. Thus, when the condition of a
number of facilities, NAVAIDs, services, or landing areas/runways are
related to the same event (e.g., date/time, facility closing,
part-timing, runway closures, etc.) each shall be issued as separate
NOTAMs.

### NOTAM State the Abnormal Status

NOTAM shall state the abnormal status of a component of the NAS and not
the normal status. The only exception is when published data is being
replaced or equipment is being returned to service, e.g., RWY 9/27 OPEN,
VOR RTS.

### NOTAM Shall be as Brief as Possible

Each NOTAM shall be as brief as possible.

## General Specifications

### Origination.

A NOTAM shall be originated and issued promptly whenever the information
to be distributed is of a temporary nature and of short duration or when
operationally significant permanent changes, or temporary changes of
long duration are made at short notice.

Note: Temporary changes of long duration (three months or longer) and
information of short duration which contains extensive text or graphics
shall be published as AIP Supplements.

### Timely Dissemination.

NOTAM should be disseminated at least five hours in advance but
generally

not more than 48 hours.

### Airspace Restriction/Activation/Modification.

NOTAM restricting airspace or activating/modifying restricted or danger
areas should be

issued at least seven days in advance.

### Planned Service Removal

Planned removal of air navigation service or facility for more than
seven days

shall be distributed as AIP Supplement.

Note: If the conditions to distribute this notice by AIP Supplement
cannot be met, a NOTAM can then be issued up to fourteen days in advance
of the removal.

### Airspace Restrictions.

[Except for NOTAM on airspace restrictions, if a NOTAM has multiple time
periods, there will not be a break of more than 48 hours between each
period.]{.mark}

Note: If more than [48]{.mark} hours advanced notice is required for a
NOTAM, USNOF shall be contacted prior to the issuance of the NOTAM.

### Conciseness.

NOTAM shall be worded as concisely as possible. The essential facts only

are to be stated. The following expressions shall not be used since

considered unnecessary wording or inadvisable:

• USE CAUTION;

• TEMPO CHANGE;

• TEMPO AMEND;

• AVBL FOR EMERG;

• EXC FOR EMERG;

• AVBL FOR FLT *ABC*;

• AVBL FOR MEDEVAC AND SKED FLT; and,

• MAKE LOW PASS PRIOR TO LANDING.

Note: With the exception of NOTAM on permanent changes to publications,
which may include abbreviations used in those publications, only ICAO
location identifiers and NOTAM abbreviations may be used.

### One Subject/One Condition. 

Each NOTAM shall deal with only one subject and one condition of the
subject. The exceptions are emergency evacuation, power failure,
temporary closure of [ATS]{.mark} units during published hours of
operations and other unusual circumstances. A NOTAMR shall refer to the
same subject and condition of the NOTAM being revised.

2.  A NOTAMN stating RWY 07/25 CLSD cannot be revised by a NOTAMR
    stating RWY 14/32 CLSD.

### Only One NOTAM in Effect at a Time.

Only one NOTAM concerning a single facility, activity or service may be
in effect at any one time. An outage of a component for an extended
period does not apply to this restriction. A second NOTAM may be issued
on another component when a shorter duration is involved.

3.  The ILS GP 06 is unserviceable for a 2-month period on one NOTAM.
    Then, the ILS 06 is unserviceable for a 2-hour period, within the
    same time frame. A second NOTAM is issued for the ILS 06
    unserviceability.

### NOTAM Impact.

Include in the NOTAM the impact on aeronautical operations when
applicable and quantify anticipated delays.

Note: Delays less then 15 minutes shall not be disseminated by NOTAM.

### USNOF NOTAM Evaluation.

With the exception of [NOTAMJ]{.mark}, all NOTAM are evaluated and if
necessary edited by the [USNOF]{.mark}.

### NOTAM Cross-Reference Coordination.

Do not make cross-reference to another NOTAM, unless prior coordination
with USNOF has been accomplished.

### Correcting Errors with NOTAMR.

Providing the subject is the same, errors occurring in a NOTAM already
processed by USNOF shall be corrected by the issuance of a NOTAMR.

### Refer to USNOF Format/Text. 

When issuing a NOTAMR, refer to the USNOF format/text appearing in the
already processed NOTAM it revises.

### Referencing Subject when Cancelling NOTAM.

When cancelling a NOTAM, the subject of reference shall be included in
the text as it was previously processed by NOF.

### Verify Related Information/Avoid Duplication.

Verify related information published in NOTAM or applicable aeronautical
publications to avoid duplication.

### NOTAM Not Issued.

NOTAM are not to be issued for record purposes after malfunctions have
been rectified.

### NOTAMN Start and Expiration Times.

Except for unplanned occurrences and permanent amendment to
publications, NOTAMN shall include a start and an expiration time.

### Imprecise Expiration Times.

If precise expiration information is not available, an indication of the
approximate duration will be expressed using [TIL APRX]{.mark}.

### Published Private NAVAID.

Published private NAVAID unserviceabilities shall be issued as a NOTAM
upon advice from the owner/operator.

### NOTAM Content Criteria.

When NOTAM content does not comply with these criteria, the NOTAM
Specialist may request the issuing unit to clarify or obtain further
information. If this is not satisfactory, the NOTAM Specialist will
contact the NOTAM originator directly. If the matter cannot be resolved
at the originator's level, it will be referred to the appropriate
authority or to the AIS Data Collection Unit for resolution. Situations
may arise where a NOTAM originator or the AIS Data Collection Unit
cannot be contacted. Under these circumstances the USNOF will take
appropriate action until the matter can be resolved.

## Procedural Applications. 

Apply the procedures in this order in conjunction with other
supplemental procedures as contained in appropriate ICAO, FAA or
Department of Defense (DOD) documents or letters of agreement provided
they do not contradict this order.

### Information to be Promulgated by NOTAM.

Note 1: Although not requiring AFTN distribution, information identified
in this section can be disseminated [by VOICE NOTAM or on ATIS]{.mark}
when determined to be appropriate.

Note 2: Maintenance, closure, unserviceability, failure or a change to
publications that has no impact on flight operations shall not be issued
as NOTAM.

## Trigger NOTAM.

### When Used.

Publication of an AIP Supplement to replace and/or modify information in
an existing NOTAM may occur at any time. A Trigger NOTAMN will be
published to refer to this AIP Supplement [(paragraph 3.8.7
refers).]{.mark}

### Cancelling NOTAM:

The previously published NOTAM containing the affected information shall
be canceled by a NOTAMC.

### Trigger NOTAM and Related Procedures.

### Trigger NOTAM -- Definition.

General definition and intended use of Trigger NOTAM are:

#### NOTAM used to announce the existence and subject content of Aeronautical Information Regulation and Control (AIRAC) Aeronautical Information Publication (AIP) Amendments or AIP Supplements of operational significance are referred to as 'Trigger NOTAM.'

#### The text of Trigger NOTAM is included in Pre-flight Information Bulletins (PIB) to ensure that pilots and operators are advised or reminded that permanent changes of operational significance take effect from the given date or that details of temporary changes of operational significance are to be found in an AIP Supplement.

### Trigger NOTAM -- General Rules.

General rules for Trigger NOTAM are:

#### AIRAC AIP Amendments and AIRAC AIP Supplements shall always be triggered by a NOTAM. Note that information concerning any circumstances listed in Annex 15 (Ref. \[1\]), Appendix 4, Parts 1 and 2, will be disseminated under the regulated 'AIRAC' system, either as an AIRAC AIP Amendment or as an AIRAC AIP Supplement.

#### The text in Item E) should not exceed 300 characters and must always start with the words "TRIGGER NOTAM" (followed only in the case of an AIP Amendment by the abbreviation PERM), a reference number of the published AIP Amendment or AIP Supplement concerned, the effective date and a brief description of its content. Effective time will be omitted in Item E) unless it differs from the default AIRAC effective time of 0000 UTC.

#### Trigger NOTAM must come into force on the effective date and time of the Amendment or Supplement that they refer to. The Trigger NOTAM will be issued as soon as possible, preferably at the publication date of the AIRAC AIP Amendment or the AIP Supplement.

#### Trigger NOTAM shall remain valid 14 days.

#### Trigger NOTAM shall be issued in the appropriate NOTAM series, according to the information to be promulgated.

#### Trigger NOTAM shall follow the normal NOTAM procedures (but see following paragraphs for exceptions).

#### The NOTAM Code 2nd and 3rd letters (= 'Subject') shall be selected from the NSC and shall never be 'XX'. If no suitable 2nd and 3rd letter combination exists then use 'FA' for Aerodrome or 'AF' for FIR.

#### The NOTAM Code for a Trigger NOTAM shall always contain 'TT' as 4th and 5th letters (= 'Condition'). This exclusive 'TT' 'Condition' indicator shall be used with all subjects of the NOTAM codes, even if not explicitly listed in the NSC tables.

#### The exclusive 'TT' 'Condition' indicator can be used to retrieve specific Trigger NOTAM from any Publishing NOF, and can additionally be used for the inclusion (or non-inclusion) of Trigger NOTAM in PIB, at a specific time before their effective date.

#### In the case of Amendments or Supplements containing information dealing with different subjects and/or locations, a single Trigger NOTAM dealing with multiple subjects and/or locations may be issued \[Note exception to Basic Rule\].

#### For FIR, publishing NOF may group all the information that relates to one or several FIR, regardless of the subject, in order to reduce the amount of NOTAM to be published \[Note exception to Basic Rule\].

#### In the cases described in paragraphs 2.7.2.10-2.7.2.12, the NOTAM qualifiers 'Traffic', 'Purpose' and 'Scope' shall be filled according to the subject of highest operational importance. Operating Procedures for AIS Dynamic Data AIS.ET1.ST05.1000-DEL-01 Page 2-40 Released Edition 2.1

When grouping different subjects it may happen that the subject of
highest operational importance does not cover qualifiers 'Traffic' and
'Scope' for all the subjects. For example, the Q-lines for two AD
subjects (ILS, VFR APCH PROC) read as following: /QICTT/I/BO/A/... and
.../QPKTT/V/BO/A.... Whichever is taken as highest operational
importance, both traffic types (I and V) concerned are never covered. In
this special case, a deviation from NSC is permitted to guarantee
necessary bulletin entries.

Note: The term 'PERM' is inserted in Item E) to stress that Item C)
contains an artificial end-date and that the information is of a
permanent nature.

### Trigger NOTAM relative to AIP SUP (AIRAC and Non-AIRAC).

#### While current ICAO SARPs do not specify a requirement for Non-AIRAC AIP Supplements to be triggered, Publishing NOF will trigger all Operationally Significant AIP SUP to ensure that all relevant elements of the integrated aeronautical information package are available for inclusion in PIB.

#### Effective Date: AIP Supplements become effective at the date and time stated in the supplement. Information to be published under the AIRAC system does not always start on an AIRAC cycle date (e.g., major works, large air exercises etc.). AIS.ET1.ST05.1000-DEL-01 Operating Procedures for AIS Dynamic Data Edition 2.1 Released Page 2-41. Consequently, both the AIP Supplement and the Item B) of the Trigger NOTAM shall contain the effective date and time of the start of the information.

#### Triggering of AIRAC information in Non-AIRAC Supplements: Due to time constraints, AIP Supplements are sometimes published to promulgate information that should have been published as an AIRAC AIP Supplement. In such exceptional cases, the operational nature of the information shall prevail and a Trigger NOTAM will be issued for this Non-AIRAC AIP Supplement. The 'Subject' and 'Condition' shall relate the information to at least the 'Purpose' 'BO', according to the NOTAM Selection Criteria.

#### Period of Validity: The general rule as stated in Para [3.8.5d]{.mark} will apply. However, if the information has a duration that is shorter than 14 days, Item C) shall reflect the date and time when the information published in the AIP Supplement will expire.

### Notification of changes to AIP SUP.

#### Changes: Any change to an AIP Supplement and its associated Trigger NOTAM, shall be published by the Publishing NOF in a way that the information itself is always clear and without any ambiguities.

#### The Supplements of 'unknown' duration could be replaced in due time by another Supplement and, in this case, the procedure described in 2.7.5.4 shall be applied to announce the cancellation of the earlier SUP. The new SUP will be triggered according to the normal procedure.

#### Notification of a later end date or time: the notification of a later end date or time of validity of the information published in an AIP Supplement is announced by replacing the Supplement and announcing this replacement by the same procedures as the one described in [Para 3.8.8b.]{.mark}

#### Notification of an earlier end date or time: exceptionally, the original end date specified in the AIP SUP may be changed to an earlier date by NOTAM. If the AIP SUP is not the subject of a valid Trigger NOTAM, a NOTAMN with validity period of 14 days is issued.

If the AIP SUP is the subject of a valid Trigger NOTAM, a NOTAMR is
issued on the date of cancellation or, if the existing valid Trigger
NOTAM is not in force, a NOTAMC is issued to cancel this NOTAM and a
NOTAMN is issued to announce the change. This NOTAMR or NOTAMN shall
remain valid for 14 days.

Operating Procedures for AIS Dynamic Data AIS.ET1.ST05.1000-DEL-01

However, for supplements with an overall validity of less than 14 days
Item C) shall reflect the date and time when the information published
in the AIP Supplement will expire.

Note: Item E) shall always contain text clearly indicating that the
planned end date has been brought forward.

above validity and Item E) procedures.

Note: The use of Condition 'LT' (instead of 'TT') in the NOTAMR to
indicate more precisely the nature of the information.

## NOTAM Accountability. [TBD]{.mark}

## Use of Contractions and Abbreviations.

Contractions and abbreviations outlined in FAAO 7930.2, Appendix 5,
Approved NOTAM Contractions, shall be used in the NOTAM system. If there
are no contractions/abbreviations, use plain text.

The Pilot/Controller Glossary shall be used to define terms in the NOTAM
system. Location identifiers used in the NOTAM system are those
contained in FAAO 7350.7, Location Identifiers.

Contractions and abbreviations published on instrument flight procedure
charts may be used in the text for Series H and P NOTAMs.

## Runway and Identification.

Identify runways by magnetic bearing indicator; e.g., 12/30, 12, or 30.
List the runway IDs in clockwise order. Where the magnetic bearing
indicator has not been established, identify the runway to the nearest
eight points of the compass; e.g., NE/SW, N/S N 200 CLSD.

## Air Defense Emergency.

Security When an air defense emergency is declared and Emergency
Security Control of Air Traffic (ESCAT) has been implemented, a NOTAM
will be issued in accordance with procedures in FAA JO 7610.4 Special
Operations Chapter 6 Emergency Security Control of Air Traffic.

## Laser Light Activity. 

The service area office where the laser activity will occur shall notify
the USNOF within 7 days of a proposed activity. Additionally, service
area offices, when coordinated with their respective FSS and/or ATCT,
may delegate notification responsibility. The USNOF will issue the
appropriate NOTAM. If the event is canceled prior to the scheduled
ending date/time, the service area office or their designee shall notify
the USNOF to cancel the NOTAM.

## WAAS Predictive NOTAMs [(TBD)]{.mark}

## SUA NOTAMs [(TBD)]{.mark}

## TERPS [(TBD)]{.mark}

## Instrument Flight Procedure NOTAMs. 

NOTAMs reflecting changes to instrument flight procedures that have been
charted and distributed are issued under series P. Series P NOTAMs
include Standard Instrument Approach Procedures (SIAPs), Obstacle
Departure Procedures (ODPs), Special Instrument Flight Procedures
(SPECIALs) Standard Instrument Departures (SIDs), Standard Terminal
Arrivals (STARs), and Charted Visual Flight Procedures (CVFPs). Except
as allowed in paragraph 4.11.2g, procedural minimums must not be lowered
by NOTAM unless fully justified as a safety of flight issue. Series P
NOTAMs may either be temporary or permanent as noted below.

### Temporary P-Series NOTAMs.

Use the keyword \[TEMPORARY\] at the beginning of the E text field when
temporary safety of flight issues require changes to any instrument
flight procedure. If the condition requiring the NOTAM will be effective
for more than four AIRAC chart cycles (224 days), a procedure amendment
via revised 8260-series form or permanent NOTAM (see below) must be
submitted as soon as possible to allow publication of the change within
the 224 day timeframe. When temporary conditions beyond the control of
the NFPO (e.g., airport construction, NAVAID restrictions, temporary
obstructions, etc.), require NOTAM action, the NFPO will ensure the line
of business (LOB) approving the temporary condition is advised of the
procedural impact and the necessity of reconciling the condition as soon
as possible so the temporary NOTAM can be cancelled within the 224-day
timeframe. If the condition cannot be corrected within 224 days,
appropriate procedure amendments must be processed. See paragraph
[3.17.6]{.mark} for long-term temporary conditions that affect Air
Traffic Service (ATS) routes.

### Permanent P-Series NOTAMs

Use the keyword \[PERMANENT\] at the beginning of the E text field when
a Series P NOTAM is used to affect an amendment to a SIAP or textual ODP
as noted above. Permanent Series P NOTAMs contain information that is
complete for charting purposes; therefore, cartographic agencies may
initiate immediate changes to charted information, based upon the
permanent NOTAM data, prior to receiving the formal amendment to the
appropriate procedure from NFDC. The following rules apply when
initiating a permanent Series P NOTAM:

#### Permanent Series P NOTAMs may only be used for SIAPs and textual ODPs.

#### Permanent Series P NOTAMs may be used to amend procedures without a complete review of the procedure. The amendment will be indicated by an alphanumeric identifier; e.g., Amdt 3A, Amdt 4C, Orig A, etc. 

#### Only one procedure shall be addressed per Permanent Series P NOTAM.

#### A hard/electronic copy of each Permanent Series P NOTAM must be affixed to the current procedure amendment and maintained in the procedures file by both the NFDC and the NFPO, for each procedure until the next full amendment is effective.

#### Permanent P-Series NOTAMs may [NOT]{.underline} be used for SPECIALs, airway changes, graphic ODPs, SIDs and STARs. 

#### Permanent Series P NOTAMs must not be used for RNAV/database driven procedures when the change(s) will affect waypoint coordinates, course (track) distances, or bearings. 

#### Permanent Series P NOTAMs may be used to lower minimums back to the original values when the temporary condition requiring an increase has been terminated.

### Responsibilities 

The NFPO and NACO R&T are responsible for developing specific internal
guidance for NOTAM preparation, quality control, transmittal,
cancellation, and follow-up actions for Series P and Z NOTAMs they
generate. This guidance must be developed in concert with the NFDC, NACO
R&T, and the USNOF. AFS-420 must be provided the opportunity to review
and comment on the procedures prior to implementation. As a minimum, the
following items must be included in the guidance:

#### Procedures to ensure that all affected ARTCC facilities are provided notification of Series P and Z NOTAMs at the time of submission, or if unable, during the next normal workday \[see Order 8260.3, Volume 1, paragraph 150\]. The NFPO/FPO must also attempt to notify the airport manager at the affected location whenever possible.

> affected terminal facilities under [paragraph 2.5.4.]{.mark}*

#### Procedures to ensure ALL Series P and Z NOTAMs are reviewed for accuracy, completeness, content, etc., prior to submission.

#### Procedures to ensure the NFDC is provided an information copy of all Series P and Z FDC NOTAMs and cancellations to ensure that the NTAP is properly maintained.

#### Procedures to ensure the USNOF notifies the submitting agency and the NFDC of all changes Series P and Z NOTAM numbering.

#### Additionally, the NFPO guidance must include procedures to ensure all FPO or Flight Inspection Operations Group (FIOG) initiated Series P and Z NOTAMs are coordinated through the NFPO.

### Procedures

#### When changes to civil procedures also affect FAA-developed military procedures at civil or joint-use airfields, the NFPO must issue a separate Series P NOTAM for the military procedure as specified in Orders 8260.15, *United States Army Terminal Instrument Procedures Service*, and 8260.32, *United States Air Force Terminal Instrument Procedures Service*. The USNOF shall forward the civil NOTAM and the reason to the cognizant military authority for appropriate DOD NOTAM action.

#### NOTAM requirements for FAA developed U.S. Army procedures must be processed under Order 8260.15. NOTAM requirements for FAA developed U.S. Air Force procedures at civil airfields must be processed under Order 8260.32.

#### Exercise caution in initiating or adding a NOTAM to an instrument flight procedure when there is already a current NOTAM in effect for the procedure. In many cases close follow-up action, including canceling and reissuing NOTAMs, will be necessary to ensure there is no confusion for pilots and chart producers. All Series P and Z NOTAMs must be issued against the [currently published]{.underline} procedure.

12. The currently published SIAP is AMDT 3 and AMDT 3A has been
    forwarded but not yet published. Another Series P NOTAM is required
    prior to the AMDT 3A effective date. Issue a \[TEMPORARY\] Series P
    NOTAM against AMDT 3. When AMDT 3A is published, the \[TEMPORARY\]
    Series P NOTAM must be canceled and reissued for AMDT 3A.

#### W hen a Series A NOTAM is issued closing an airport permanently, a Series P NOTAM need not be issued denying use of an instrument flight procedure. A routine procedure cancellation should be processed as soon as possible.

#### When a Series A NOTAM is issued closing a runway, a Series P NOTAM need not be issued denying straight-in minimums to that runway. If the closing is permanent, routine procedure cancellations, including takeoff/departure procedures, must be processed immediately.

#### When radio control of approach lights or runway lights is commissioned or the frequency is changed, Flight Inspection issues a Series A NOTAM in accordance with Order 8200.1, *United States Standard Flight Inspection Manual*.

#### When a Series N NOTAM is issued to shut down a facility permanently, only routine cancellations of procedures predicated on that facility are required. Series P NOTAMs may be required for other procedures supported by the affected facility.

#### When a Series N NOTAM is issued for a facility shutdown or outage, a Series P NOTAM denying instrument flight procedure use is not required for those procedures using only that facility. However, other procedures in the vicinity must be reviewed to determine if that facility supports courses or fixes; in such cases, those procedures require a Series P NOTAM. Particular attention must be given to fixes supporting step down minimums and missed approach procedures, which are predicated on the out-of-service facility. It is not necessary to issue NOTAMs for fixes and terminal route segments, which are related to unusable airway segments from the subject facility. Do not issue "Radar Required" NOTAMs on unusable or restricted airway segments.

#### When a Series N NOTAM removes a localizer from service, the approach procedure is unusable. If the GS is out, the precision approach is unusable. If other ILS components are out, the inoperative table applies.

#### When Airways Facilities issues a Series N NOTAM suspending Category II/III minimums, the NFPO will then amend procedures as required.

### Area Navigation (RNAV) Substitution. 

Aircraft equipped with RNAV systems may substitute them for inoperative
ground NAVAIDs. However, RNAV systems [must not]{.underline} be
substituted for NAVAIDS providing final approach course guidance on
instrument approach procedures.

#### When the use of an instrument flight procedure is restricted or prohibited by NOTAM because of a NAVAID (VOR, TACAN, NDB, compass locator, or DME) outage, the NOTAM does not apply to aircraft equipped with suitable GPS RNAV systems. For clarification, state the reason for the restriction following the text of the Series P NOTAM (Item E). 

> *Examples:*
>
> A DME antenna is out of service: \"DME MINIMUMS NA EXCEPT FOR AIRCRAFT
> EQUIPPED WITH SUITABLE RNAV SYSTEM WITH GPS, ORD DME OTS.\"
>
> An LOM used for procedure entry and/or missed approach clearance limit
> for an ILS approach is out of service: \"PROCEDURE NA EXCEPT FOR
> AIRCRAFT EQUIPPED WITH SUITABLE RNAV SYSTEM WITH GPS, GR LOM OTS.\"
>
> A VOR used in a departure procedure is out of service: \"GEYSER THREE
> DEPARTURE NA EXCEPT FOR AIRCRAFT EQUIPPED WITH SUITABLE RNAV SYSTEM
> WITH GPS, JAC VOR OTS.\"

#### In certain circumstances, AFS‑400 may determine that the use of RNAV systems that utilize DME/DME/IRU inputs should be allowed. In these instances, insert the phrase \"OR DME/DME/IRU\" after \"SUITABLE RNAV SYSTEM WITH GPS.\" Include any required DME facilities to support DME/DME/IRU operations.

#### *Example:* \"HOOVER THREE DEPARTURE NA EXCEPT FOR AIRCRAFT EQUIPPED WITH SUITABLE RNAV SYSTEM WITH GPS OR DME/DME/IRU, PGS VOR OTS. BLD AND DRK MUST BE OPERATIONAL FOR DME/DME/IRU ON PEACH SPRINGS TRANSITION. DRAKE TRANSITION NA FOR DME/DME/IRU.\"

### AIR TRAFFIC SERVICE ROUTE (ATS) NOTAMs. 

When a restriction or a change to an ATS route requires a NOTAM, the
NFPO must prepare and forward a Series Z NOTAM for each ARTCC affected.
Enter the ARTCC identifier as Item A. If the restriction is expected to
exceed 224 days, coordinate with the appropriate ATO Service Area for a
determination whether revised airway rulemaking is necessary.

### SPECIAL INSTRUMENT APPROACH PROCEDURES (SPECIALS) NOTAMs.

Temporary Series P NOTAMs may also be used to promulgate safety of
flight information relating to Specials provided the location has a
valid landing area identifier and is serviced by the U.S. NOTAM system.
NFPO NOTAM Entry System (NES) will provide immediate feedback as to
whether the location is included in the NOTAM system. There are four
possible considerations to determine FDC NOTAM action for Specials.

#### If the Special [is]{.underline} maintained by the NFPO and the location ***[is]{.underline}*** in the U.S. NOTAM system, then procedures for NOTAM processing by the NFPO will be similar to the procedures used for public, Part 97 instrument approach procedures. Additionally, when preparing the NOTAM for submission, include the prefix \[SPECIAL TEMPORARY\] at the beginning of the E text field. The NFPO will notify the Regional Flight Standards Division, All-Weather Operations Program Manager (RFSD-AWOPM) as soon as practicable. 

#### If the Special **[is not]{.underline}** maintained by the NFPO but the location ***[is]{.underline}*** in the U.S. NOTAM system, then the organization responsible for maintaining the procedure will notify the applicable RFSD-AWOPM of the change/outage. The RFSD-AWOPM will contact the NFPO with the appropriate information, who will take appropriate NOTAM action. If the RFSD-AWOPM cannot be immediately contacted and the condition is critical to flight safety, the Regional FPO or the NFPO will be contacted directly and provided adequate information to initiate immediate NOTAM action. The NFPO will notify the RFSD-AWOPM as soon as practicable. 

Note: After duty hours, contact the stand-by NFPO representative at
(405) 954-8260.

#### If the Special **[is]{.underline}** maintained by the NFPO and the location ***[is not]{.underline}*** in the U.S. NOTAM system, then the NFPO will notify the applicable RFSD-AWOPM of the change/outage. The RFSD-AWOPM must contact the user(s) of the procedure to disseminate appropriate action (e.g., NA the procedure, raise applicable minimums, etc.). 

#### If the Special **[is not]{.underline}** maintained by the NFPO and the location ***[is not]{.underline}*** in the U.S. NOTAM system, then the organization responsible for maintaining the procedure will notify the applicable RFSD-AWOPM of the change/outage. The RFSD-AWOPM must contact the user(s) of the procedure to disseminate appropriate action (e.g., NA the procedure, raise applicable minimums, etc.). 

###  NOTAM CONTENT

#### Series P NOTAMs must identify the procedure being amended using the identification as published and the current amendment number. The NOTAM must be as concise as possible, and must NOT contain information that could be published at a later date by a routine amendment. For example, changes to the touchdown zone or airport elevation, which does not affect visibility minimums, do not require NOTAM action

#### The text must be prepared by the NFPO using plain language and those contractions found in the NTAP and allowed under Order 8260.19 (current edition). Specialists must keep in mind that the NOTAM is directed to the pilot, and should be worded so that the intended change will not be misinterpreted. Avoid the use of internal cartographic instructions that have no meaning to pilots. Spell out NAVAID names in clear text followed by the identifier. If it appears that the NOTAM length will exceed 20 lines, refer to paragraph xxxxx.

#### For temporary obstructions, include the type, elevation, distance, and direction from the airport or runway threshold, as appropriate, as the last line of the NOTAM text. Do not preface this information with "CHART:"

#### The operational system used by the ATO to transmit P-Series and Z-Series NOTAMs to the USNOF must contain a remarks section to document the reason for the NOTAM. This reason will not be a part of the NOTAM text, but will be used to provide a historical record for the reason for the NOTAM.

#  SNOWTAMs and ASHTAMs. 

SNOWTAMS and ASHTAMs will be issued in accordance ICAO Annex 15. An
ASHTAM is required for an operationally significant change in volcanic
activity, the location, date and time of volcanic eruptions and/or
horizontal and vertical extent of volcanic ash cloud, including
direction of movement, flight levels and routes or portions of routes
which could be affected.

## Operationally relevant messages. 

Two types of operationally relevant messages are described in ICAO
documentation and distributed via the AFS. As these messages are
operationally relevant, their processing is required to enable database
storage and consequently further retrieval for their incorporation in
PIB. The concerned messages are: SNOWTAM and ASHTAM.

## SNOWTAM and ASHTAM are expected to be received in their defined format. 

Therefore, it is anticipated that they will neither be edited nor
corrected nor summarized. If a message is detected as received obviously
incorrect (e.g., garbled), a query will be addressed to the originator
for clarification. This processing can be done by individual or
centralized Units.

## SNOWTAM

###  Definition

#### A special series NOTAM notifying the presence or removal of hazardous conditions due to snow, ice, slush, or standing water associated with snow, slush and ice on the movement area by means of a specific format.

#### During periods when deposits of snow, ice, slush or water associated with these conditions remain on the aerodrome pavements, information on such conditions should be disseminated to all to whom the information is of direct operational significance. Use of the ICAO Doc 8400 abbreviations (Ref \[3\]) and plain language is also permissible.

#### For details of SNOWTAM items refer to the ICAO Annex 15 (Ref. \[1\]), Appendix 2 and Doc 8126 (Ref \[2\]), Ch 6 Appendix A.

#### A list of aerodromes for which SNOWTAM are likely to be issued shall appear in an AIS publication (AIP, AIP SUP or AIC) together with details of the originators and of the numbering system to be used.

#### It is recommended to adopt a numbering sequence starting either at the beginning of the snow season or at the beginning of the year.

#### It will be necessary for systems to identify the latest SNOWTAM for each affected aerodrome by reference to the serial number and observation time.

#### Only one SNOWTAM can be valid for each affected aerodrome at any one time.

#### The next planned observation may be declared in Item S), but whenever a significant change of the weather condition occurs, a new SNOWTAM shall be

#### published and will completely replace any SNOWTAM previously issued.

#### The maximum validity of a SNOWTAM is 24 hours.

#### The incorporation of SNOWTAM in PIB is highly recommended, as it improves pre-flight briefing and provides airline operators with more comprehensive information.
