1.7 General NOTAM Information.

1.7.1 Definition of NOTAM

A NOTAM is a notice distributed by means of telecommunication containinginformation concerning the establishment, conditions or change in anyaeronautical facility, service, procedure or hazard, the timely knowledge of whichis essential to personnel concerned with flight operations.

1.7.2 Purpose of NOTAM Distribution

The provision of information, which may affect safety, in advance of the event towhich it relates, and for unserviceabilities that cannot be foreseen. Thus, torealize its purpose a NOTAM should be received by the addressee in sufficienttime for any required action to be taken. The value of a NOTAM lies in its “newscontent” and its residual historical value is therefore minimal.

1.7.3 Application

This FAAO 7930.2N, NOTAM handbook prescribes the procedures to be usedfor the determination, origination, preparation and distribution of NOTAM inthe United States. The procedures are based on the International Civil AviationOrganization (ICAO) Annex 15 to the Convention on International Civil Aviation,Aeronautical Information Services.

1.7.4 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.

1.8 UNITS OF MEASUREMENT.

1.8.1 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.

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.

1.8.2 Time System.

The time is expressed in UTC (coordinated universal time) and indicated to thenearest minute. The day begins at 0000 hours and ends at 2359 hours.

1.8.3 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 themonth; DD the day; HH the hours; and MM the minutes.

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

1.8.4 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

3.4 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.

3.4.1 Format.

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

3.4.2 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.

3.4.3 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.

3.4.4 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.

3.4.5 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.



3.4.6 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.

3.4.7 NOTAM Shall be as Brief as Possible

Each NOTAM shall be as brief as possible.

3.5 General Specifications

3.5.1 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.

3.5.2 Timely Dissemination.

NOTAM should be disseminated at least five hours in advance but generallynot more than 48 hours.

3.5.3 Airspace Restriction/Activation/Modification.

NOTAM restricting airspace or activating/modifying restricted or danger areas should beissued at least seven days in advance.

3.5.4 Planned Service Removal

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

3.5.5 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.



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

3.5.6 Conciseness.

NOTAM shall be worded as concisely as possible. The essential facts onlyare to be stated. The following expressions shall not be used sinceconsidered 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.

3.5.7 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 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.

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

3.5.8 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.

Example 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.

3.5.9 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.

3.5.10 USNOF NOTAM Evaluation.

With the exception of NOTAMJ, all NOTAM are evaluated and if necessary edited by the USNOF.

3.5.11 NOTAM Cross-Reference Coordination.

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

3.5.12 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.

3.5.13 Refer to USNOF Format/Text.

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

3.5.14 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.

3.5.15 Verify Related Information/Avoid Duplication.

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

3.5.16 NOTAM Not Issued.

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

3.5.17 NOTAMN Start and Expiration Times.

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



3.5.18 Imprecise Expiration Times.

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

3.5.19 Published Private NAVAID.

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

3.5.20 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.

3.6 Procedural Applications.

3.8 Trigger NOTAM.

3.8.1 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).

3.8.2 Cancelling NOTAM:

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

3.8.3 Trigger NOTAM and Related Procedures.

3.8.4 Trigger NOTAM – Definition.

General definition and intended use of Trigger NOTAM are:

a. 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.’

b. 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.

3.8.5 Trigger NOTAM – General Rules.

General rules for Trigger NOTAM are:a. 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.

b. 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.

c. 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.

d. Trigger NOTAM shall remain valid 14 days.

Example 5: B) 0503170000 (AIRAC effective date and time)C) 0503310000 (AIRAC effective date and time + 14 days)AIS.ET1.ST05.1000-DEL-01 Operating Procedures for AIS Dynamic Data Edition 2.1 Released Page 2-39

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

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

g. 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.

h. 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.

i. 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.

j. 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].

k. 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].

Example 6: Q) LEXX/QAETT/IV/BO/E/065/660/4229N00152E999 A) LECB LECM B) 0702150000 C) 0703010000E) TRIGGER NOTAM - PERM AIRAC AIP AMDT 2/07 WEF 15FEB2007.



CHANGES TO AIRSPACE CLASSIFICATION AND UPPER LIMIT OF CONTROLLED AIRSPACE.

l. For Aerodromes, a separate Trigger NOTAM shall be issued for each aerodrome. Different subjects relating to the same aerodrome, may however be grouped in the same NOTAM [Note exception to Basic Rule].

Example 7: Q) EFIN/QPATT/I/BO/A/000/999/6031N02216E005A) EFTU B) 0702150000 C) 0703010000E) TRIGGER NOTAM-PERM AIRAC AIP AMDT 2/07 WEF 15FEB2007. CHANGES TO STAR AND TO WGS 84 COORDINATES

m. 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.

Example 8: In the following case, the ‘Traffic’ qualifier ‘IV’ is a combination to cover both subjects (QICTT and QPKTT): Q) EFIN/QICTT/IV/BO/A/000/999/6240N02937E005 A) EFJO B) 0511240000 C) 0512082359 E) TRIGGER NOTAM - PERM AIRAC AIP AMDT 91/05 WEF 24NOV2005. INTRODUCTION OF ILS RWY28 AND REVISED VFR APCH PROC.

3.8.6 Trigger NOTAM relative to AIRAC AIP AMDT.

a. AIRAC Amendments represent permanent changes to the AIP on a predefined date.

b. Effective Date: AIRAC AIP Amendments become effective on the AIRAC cycle date. Item B) will always contain the AIRAC effective date and time.

Example 9: Q) LOVV/QARTT/I/BO/E/245/999/4720N01330E999



A) LOVVB) 0503170000C) 0503310000E) TRIGGER NOTAM - PERM AIRAC AIP AMDT 3/05 WEF 17MAR2005.IMPLEMENTATION OF NEW ATS ROUTE UA15.

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.



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

a. 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.

b. 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.

c. 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.

d. Period of Validity: The general rule as stated in Para 3.8.5d 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.

Example 10: Q)EFIN/QRDTT/IV/BO/W/000/040/6637N02825E016A)EFIN B)0512092200 C)0512121200E)TRIGGER NOTAM - AIP SUP 68/05 WEF 9DEC2005.TEMPO DANGER AREAEF D148 SALLA ACT.F)SFC G)4000FT AMSL



3.8.8 Notification of changes to AIP SUP.

a. 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.

b. 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.

c. 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.

d. 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 Page 2-42 Released Edition 2.1.

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.

Example 11: Original: A0034/05 NOTAMNQ) ESAA/QFATT/IV/BO/A/000/999/5739N01217E005A) ESGGB) 0504140600C) 0504280600E) TRIGGER NOTAM – AIRAC AIP SUP 14/05 WEF14APR2005.

C) 0505110935E) REF AIRAC AIP SUP 14/05 WORKS HAVE BEENCOMPLETED. THE RESTRICTIONS ARE NO LONGER INFORCE.

Note: If the AIP SUP was not originally triggered, a NOTAMN may also be issued exceptionally to announce the cancellation in accordance with the 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.

3.9 NOTAM Accountability. TBD

3.10 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.

3.11 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.

3.12 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.

3.13 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.

3.14 WAAS Predictive NOTAMs (TBD)

3.15 SUA NOTAMs (TBD)

3.16 TERPS (TBD)

3.17 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.

3.17.1 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 for long-term temporary conditions that affect Air Traffic Service (ATS) routes.

3.17.2 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:



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

b. 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.

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

d. 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.

e. Permanent P-Series NOTAMs may NOT be used for SPECIALs, airway changes, graphic ODPs, SIDs and STARs.

f. 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.

g. 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.

3.17.3 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:

a. 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.

Note: ARTCCs are responsible for forwarding NOTAM information to the affected terminal facilities under paragraph 2.5.4.

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

c. 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.



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

e. 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.

3.17.4 Procedures

a. 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.

b. 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.

c. 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 procedure.

Example 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.

d. 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.

e. 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.



f. 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.

g. 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.

h. 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.

i. 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.

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

3.17.5 Area Navigation (RNAV) Substitution.

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

a. 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."

b. 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.

c. 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."

3.17.6 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.

3.17.7 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.

a. If the Special is maintained by the NFPO and the location is 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.

b. If the Special is not maintained by the NFPO but the location is 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.

c. If the Special is maintained by the NFPO and the location is not 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.).

d. If the Special is not maintained by the NFPO and the location is not 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.).



3.17.8 NOTAM CONTENT

a. 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

b. 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.

c. 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:”

d. 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.

CHAPTER 6: 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.

6.1 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.

6.2 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.

6.3 SNOWTAM

6.3.1 Definition

a. 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.

b. 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.

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