1. Introduction
This guidance has been created with the objective of supporting NOTAM sponsors in the
preparation and submission phase to enable clear and concise provision of information to its
readers.
1.1 NOTAM Definition - (ICAO Annex 15)
“A notice distributed by means of telecommunication containing information concerning
the establishment, condition or change in any aeronautical facility, service, procedure or
hazard, the timely knowledge of which is essential to personnel concerned with flight
operations.”
1.2 NOTAM Proliferation
Statistics indicate that the number of NOTAM being distributed globally continues to
escalate. The UK NOTAM office alone transmits in excess of 5558 NOTAM every month.
As the complexities around services and facilities increase, so the requirement to deliver
consistent information in an accurate and timely manner becomes vital.
1.3 NOTAM Sponsorship
In practical terms planned changes to facilities and services affecting the safe operation
of aircraft should be notified to AIS giving as much notice as possible. While un-
serviceable and un-planned events can only be announced as they occur.
1.4 Assessment Process
If a hazard is assessed as having a significant impact on the safe operation of an aircraft
or a change to the information published in the AIP has taken place, then a NOTAM may
be considered to announce the circumstances.
1.5 A NOTAM shall be considered for the following:
a) Establishment, closure or significant changes in operation of aerodrome(s) or
heliport(s) or runways.
b) Establishment, withdrawal or significant changes in operation of aeronautical
services (aerodromes, AIS, ATS, communications, navigation and surveillance
(CNS), meteorology (MET), search and rescue (SAR), etc.).
c) Establishment, withdrawal or significant changes in operational capability of radio
navigation and air-ground communication services. This includes: interruption or
return to operation, change of frequencies, change in notified hours of service,
change of identification, change of orientation (directional aids), change of
location, power increase or decrease amounting to 50 per cent or more, change
in broadcast schedules or contents, or irregularity or unreliability of operation of
any radio navigation and air-ground communication services or limitations of relay
stations including operational impact, affected service, frequency and area;
d) Unavailability of back-up and secondary systems, having a direct operational
impact.
e) Establishment, withdrawal or significant changes to visual aids.

UK NOTAM GUIDANCE MATERIAL
f) Interruption of or return to operation of major components of aerodrome lighting
systems.
g) Establishment, withdrawal or significant changes to procedures for air navigation
services.
h) Occurrence or correction of major defects or impediments in the manoeuvring
area.
i) Changes to and limitations on availability of fuel, oil and oxygen.
j) Major changes to search and rescue facilities and services available.
k) Establishment, withdrawal or return to operation of hazard beacons marking
obstacles to air navigation.
l) Changes in regulations requiring immediate action, eg prohibited areas for SAR
action.
m) Presence of hazards not otherwise promulgated, which affect air navigation
(including obstacles, military exercises and operations, intentional and
unintentional radio frequency interferences, rocket launches, displays, fireworks,
sky lanterns, rocket debris, races and major parachuting events.
n) Conflict zones which affect air navigation (to include information that is as
specific as possible regarding the nature and extent of threats of that conflict
and its consequences for civil aviation)
o) Planned laser emissions, laser displays and search lights if pilots’ night vision is
likely to be impaired.
p) Erecting or removal of, or changes to, obstacles to air navigation in the take-
off/climb, missed approach, approach areas and runway strip.
q) Establishment or discontinuance (including activation or deactivation) as
applicable, or changes in the status of prohibited, restricted or danger areas.
r) Establishment or discontinuance of areas or routes or portions thereof where the
possibility of interception exists and where the maintenance of guard on the VHF
emergency frequency 121.5 MHz is required.
s) Allocation, cancellation or change of location indicators.
t) Changes in aerodrome/heliport rescue and firefighting category provided (see
Annex 14, Volume I, Chapter 9, and Attachment A, Section 17).
u) Presence or removal of, or significant changes in, hazardous conditions due to
snow, slush, ice, radioactive material, toxic chemicals, volcanic ash deposition or
water on the movement area.
v) Outbreaks of epidemics necessitating changes in notified requirements for
inoculations and quarantine measures.
w) Observations or forecasts of space weather phenomena, the date and time of
their occurrence, the flight levels where provided and portions of the airspace
which may be affected by the phenomena.
x) 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.
y) Release into the atmosphere of radioactive materials or toxic chemicals following
a nuclear or chemical incident, the location, date and time of the incident, the
flight levels and routes or portions thereof which could be affected and the
direction of movement.
z) Establishment of operations of humanitarian relief missions, such as those
undertaken under the auspices of the United Nations, together with procedures
and/or limitations which affect air navigation; and
aa) Implementation of short-term contingency measures in cases of disruption, or
partial disruption, of ATS and related supporting services
1.6 The following information shall not be notified by NOTAM:
a) Routine maintenance work on aprons and taxiways which does not affect the
safe movement of aircraft.
b) Runway marking work, when aircraft operations can safely be conducted on
other available runways, or the equipment used can be removed when
necessary.

c) Temporary obstructions in the vicinity of aerodromes/heliports that do not affect
the safe operation of aircraft.
d) Partial failure of aerodrome/heliport lighting facilities where such failure does not
directly affect aircraft operations.
e) Partial temporary failure of air-ground communications when suitable alternative
frequencies are known to be available and are operative.
f) The lack of apron marshalling services and road traffic control.
g) The unserviceability of location, destination or other instruction signs on the
aerodrome movement area.
h) Parachuting when in uncontrolled airspace under VFR (see 6.3.2.3 m), when
controlled, at promulgated sites or within danger or prohibited areas.
i) Training activities by ground units.
j) Unavailability of back-up and secondary systems if these do not have an
operational impact.
k) Limitations to airport facilities or general services with no operational impact.
l) National regulations not affecting general aviation.

coordinated of duration of less than one hour.
r) Closure or unavailability of, or changes in, operation of aerodrome(s)/heliport(s)
outside the aerodrome(s)/heliport(s) operational hours; and
s) Other non-operational information of a similar temporary nature.
1.7 Permanent Changes to the UK Civil AIP
Permanent Changes to the UK AIP are to be submitted using the online process available
from the AIS Portal https://www.aurora.nats.co.uk/
Note: More information about submitting AIP Change Requests and publishing other
aeronautical information products can be found here: https://nats-uk.ead-it.com/cms-
nats/opencms/en/Publications/submit-change-request/
Do not use AFTN to sponsor a Permanent NOTAM, they should be submitted via Aurora
Data Originators Portal as part of the AIP Change Request. However, during out-of-hours,
if a Perm change is imminent and critical to Flight Safety then a temporary NOTAM may
be issued for a maximum of 7 days. The sponsor must submit an AIP CR as soon as
possible but within 7 days.
1.8 Regulatory approvals
Compliance with regulatory approval requirements shall not inhibit the urgent distribution
of aeronautical information necessary to ensure the safety of flight.
Regulatory approvals of items submitted via Aurora Data Originators Portal are sent to
the CAA directly by the AIS.
Notifying the CAA about any temporary changes promulgated via NOTAM, to data items
requiring regulatory approval, remain the responsibility of the Sponsor but UK NOF may be
asked for assistance or coordination.
10th August 2023
3 of 13
UK NOTAM GUIDANCE MATERIAL
When an aerodrome wishes to temporarily increase their declared distance, eg special
events, the AD Operator must obtain prior approval from (SRG) before a NOTAM is
proposed.
Note: More information about regulatory approvals and notifications process is provided
in CAP 1054.
1.9 Permanent Changes to the UK Mil AIP
Military units can issue permanent NOTAM via AFTN; however, the sponsor is to advise
No 1 AIDU as soon as possible to ensure the UK Mil AIP is updated.
Note: UK MIL AIP is available at https://www.aidu.mod.uk/aip/, more information on
submitting changes to the UK MIL AIP and publishing other MIL aeronautical information
products can be found here: https://www.aidu.mod.uk/aip/userSupport.html
1.10 Temporary Changes
The principle means of delivering temporary NOTAM proposals to AIS is by use of the
AFTN. If AFTN is not available due to connectivity issues, then sponsors can email their
proposal to [email protected] using the NOTAM form at the following
address: https://nats-uk.ead-it.com/cms-nats/opencms/en/NOTAM/#NOTAM_REQUEST_FORM
Authorised sponsors that do not have an AFPEX account can sign up for a free NOTAM
only account.
AFPEX can be found here: www.myafpex.co.uk
Apply for an AFPEX account: https://ts1.flightplanningonline.co.uk/applyingForAnAccount.html
AFPEX NOTAM Help/Guide can be found here: https://www.myafpex.co.uk/guides/notam.php
1.11 NOTAM Duration Information of a permanent character
Within three months from the issuing of a permanent NOTAM, the information contained
in the NOTAM shall be included in the aeronautical information products affected (eg AIP,
charts, datasets).
If at the time of NOTAM submission, it is clear that the information is permanent, PERM
NOTAM should be issued. Please see paragraph 1.7 Permanent Changes to the UK Civil
AIP above.
Information of a temporary character
Within three months from the issuing of a temporary NOTAM of long duration, the
information contained in the NOTAM shall be included in other aeronautical information
products.
It means that if at the time of NOTAM submission, it is clear to the Sponsor that the
information is temporary but of long duration, NOTAM can be issued for 90 days, and
other aeronautical information products must be proposed by the Sponsor to promulgate
the information beyond the period of validity of such NOTAM.
When a NOTAM with estimated end of validity unexpectedly exceeds the three-month
period, a replacement NOTAM can be issued once. In each case UK NOF should be made
aware of the re-issuance. A request for a second (and further) re-issuance of the same
NOTAM is subject to CAA’s approval. The CAA may agree to re-issue NOTAM if sufficient
justification is provided by the Sponsor and it is clear that it is necessary to ensure safety
of aircraft operations.
Note: UK NOF records every re-issued NOTAM and provided justification for audit
purposes.

2. Type
2.1 Airspace Activities
Planned Activities such as air exercises, flight trials, air displays, ballooning, kite flying
etc impacting upon normal flying operations must be brought to the attention of other
airspace users. To facilitate this, a department within the CAA, Airspace Regulation (AR)
([email protected] 01293 983880) acts as a focal point to validate and co-ordinate
airspace activities taking place within the UK.
Organisers of such events are required to contact the CAA giving as much notice as
possible. An individual assessment of each activity is conducted by an Airspace Specialist
resulting in an appropriate method of notification on behalf of the organiser.
Note: More information about event and obstacle notification can be found here:
https://www.caa.co.uk/Commercial-industry/Airspace/Event-and-obstacle-
notification/Event-and-obstacle-notification/
2.2 ‘Out-of-Hours’ Nav Warnings
a) When the NOF receives a NOTAM for a Nav Warning request outside the CAA AR
operational hours which has not been de-conflicted by CAA AR, NOF shall inform the
sponsor about the NOTAM policy and advise the sponsor to contact CAA AR, the NOF
should also inform CAA AR about the request.
b) However where there is an urgent need to distribute a NOTAM for a Nav Warning to ensure
safety of operations and when contact with CAA AR is not possible before the start of the
activity (or occurrence of any other hazard to air navigation) and the sponsor has
confirmed that the activity (or hazard) cannot be cancelled (or hazard eliminated) or
delayed, a NOTAM should be published. Both CAA AR and CAA AIMR should be notified via
email including a copy of the NOTAM (marked HIGH IMPORTANCE). CAA AR shall de-
conflict such notifications at the earliest opportunity.
c) It is the Sponsor’s responsibility to notify AR in advance of any planned unusual aerial
activities taking place outside an ATZ to ensure de-confliction of the airspace. Publication
of a NOTAM cannot be considered as a means of notifying the CAA about the activity and
must not be considered as approval for the activity.
d) CAA AR Operational hours for the purpose of the arrangements in this policy are:
a. Mon – Fri 08:30 – 16:30 (excluding UK public bank holidays and notified closed
periods).
e) The above policy is valid for new NOTAM requests as well as changes and cancellations of
published NOTAM for Nav Warnings unless agreed otherwise between CAA AR, NOF and
the sponsor(s).
2.3 Unlicensed Aerodromes
Unlicensed aerodromes with or without an ICAO 4-letter location indicator are able to
propose NOTAM for safety related subjects for facilities and services at their aerodrome.
Such information will be issued as an E Series NOTAM. Unlicensed aerodromes with or
without an AFTN that have unusual aerial activities shall be brought to the attention of
CAA Airspace Regulation who will consider an H series NOTAM.
2.4 En-route Obstacles
The ENR 5.4 section of the UK AIP contains a list of all known obstacles in the UK FIRs
above 100m/328ft AGL. The information includes unique references, obstacle types and
whether lighting is known to be fitted or not. The source of all information published in
this section is the Defence Geographic Centre (DGC).
10th August 2023
5 of 13
UK NOTAM GUIDANCE MATERIAL
If a permanent or temporary change is known to have taken place, e.g. a new en-route
obstacle or a lighting outage, then the CAA must be notified.
Note: More information about event and obstacle notification can be found here:
https://www.caa.co.uk/Commercial-industry/Airspace/Event-and-obstacle-
notification/Event-and-obstacle-notification/
2.5 Aerodrome Obstacles/safeguarding
An aerodrome has the sole responsibility for notifying relevant obstacles affecting
aerodrome operations in accordance with CAP 738 and 785. Consequently, a NOTAM
proposal received by NOF from an aerodrome notifying obstacles can therefore be
regarded as necessary for the purposes of aerodrome safeguarding.
A NOTAM proposal received by NOF from an aerodrome must include –
i.
Type of obstacle.
ii. Obstacle position and location, represented by geographical coordinates in
degrees, minutes, seconds and tenths of seconds if required for accuracy.
iii. Obstacle height in AGL and AMSL in feet
iv. Obstacle marking, and type and colour of obstacle lighting (if any).
(NOF will defer to proposer if any of these criteria are missing.)
The NOF will promulgate the NOTAM as scope ‘AE’ thereby ensuring the information is
included in an aerodrome PIB and En-route PIB.
CAA/AR section propose ‘N’ series (En-route) NOTAM for obstacles over 100m/328ft AGL
and not affecting aerodrome operations that are notified to CAA by owners/operators.
Obstacles above 100m/328ft AGL that are outside of the safeguarding area, but within
an aerodrome’s controlled airspace shall be promulgated using scope ‘AE’ thereby
ensuring the information will appear in an aerodrome (PIB) and En-route PIB.
2.6 Aerodrome NOTAM Processing
If the obstacle is assessed as affecting more than one licensed aerodrome, then additional
NOTAM may be issued to ensure that the notification appears on all relevant PIB. One
NOTAM will be scoped as AE (Aerodrome and En-route), any additional NOTAM will be
scoped A to identify other affected aerodrome/s.
2.7 New/Temporary obstacles regarding the safe operation of aircraft
All obstacles over 100 m (328ft) AGL are to be notified to the CAA. It is mandatory to
notify the CAA of any obstacle of a height of 100m AGL and more. This requirement
applies regardless of where the obstacle is located.
Obstacles within aerodrome notification areas should be notified to the relevant
aerodrome operator.
Occasionally unverified reports are received from the public describing the presence of
an obstacle. In response to any report received ‘out of hours’, AIS will raise a NOTAM
containing a statement “UNVERIFIED REPORT OF OBSTACLE” until verification by the CAA
or MAMC can take place.

2.11 Firework Displays
Information relating to firework displays that do not exceed 1000ft AGL will only routinely
be promulgated by NOTAM if the display falls within the area defined in Annex B to CAP
736. NOTAM action may also be taken if the display lies inside CAS or close to known
low-level aircraft routes.
3. NOTAM
3.1 The AFTN NOTAM Proposal
As a general principle, each submission should deal with only one subject and one
condition. Avoid sending a NOTAM proposal that describes a multitude of disconnected
subjects. The information must be clear and unambiguous giving the reader the ability
to quickly assess the impact.
Be mindful that the information will be delivered to an international audience where a
great many recipients will not have English as their primary language.
All proposals should be transmitted to the UK NOF using the AFTN address EUECYIYP.
This address is used by those NOF Offices that have adopted the European AIS Database
(EAD) service for broadcasting their NOTAM.
When composing the NOTAM Proposal, it is important that the first line of text is
constructed according to an explicit format. The message is to be prefixed with the type
10th August 2023
7 of 13
UK NOTAM GUIDANCE MATERIAL
of NOTAM i.e. NOTAMN to announce a new NOTAM, NOTAMR to replace a current
NOTAM and NOTAMC to cancel a NOTAM.
The use of PROPOSAL EGGN in the first line of text is compulsory and signifies that the
message is for the attention of the UK NOTAM Office.
After the first line, the message can take any format. The closer the content is aligned to
the NOTAM format the quicker AIS will be able to process the message for distribution.
Some examples follow:
NOTAMN PROPOSAL EGGN
EASTERN TAXIWAY CLOSED DUE RESURFACING
FROM 0800 TO 2300 ON 24 JAN

NOTAMR PROPOSAL EGGN A0123/12
EXTEND NOTAM A0123/12 UNTIL 28 JUN 1500 DUE CONTINUED OUTAGE
3.2 NOTAM Format
NOTAM are required to conform to an explicit template. Using the example below, an
explanation of the format follows:
A1234/14 NOTAMN
Q) EGTT/QMRLC/IV/NBO/A/000/999/5129N00028W005
A) EGLL
B) 1408231500 C) 1409310500
D) 1500-1600, 0430-0500
E) RWY 09R/27L CLOSED DUE WIP
3.3 The NOTAM Construct:
A1234/13 represents the NOTAM Series, followed by a sequential 4-digit number,
followed by two digits to indicate the year. (Max 9999/YY).
NOTAMN Indicates this is a new NOTAM. Other options are R for NOTAM replacing
another or C for one cancelling another. Replacement NOTAM can only be used to replace
a NOTAM that is already in effect
Q) EGTT/QMRLC/IV/NBO/A/000/999/5129N00028W005
The Qualifying line, or Q Line, is an AIS tool used to categorise the NOTAM according to
its scope. It consists of up to eight fields separated by a stroke (/) comprising FIR, Q
Code, Traffic, Purpose, Scope, Vertical Limits, Co-ordinates and Radius.
EGTT is an ICAO code, identifying the (London) FIR to which the NOTAM refers. Should
the activity take place in more than one FIR then the code EGXX is applied and the
specific FIRS affected are inserted into field A of the NOTAM
QMRLC is a 5 letter NOTAM code identifying subject and status. In this case MR is a
Runway, LC indicates a closed status. IV indicates that this information is significant for
both IFR and VFR operations while NBO indicates a message for immediate attention, for
inclusion in a PIB and operationally significant.
10th August 2023
8 of 13
UK NOTAM GUIDANCE MATERIAL
A represents the scope which in this case is an Aerodrome NOTAM as opposed to an En-
Route E NOTAM or Navigation Warning W. Combinations AE and AW can also be applied
according to the subject being described.
000/999 represents the lower and upper limits expressed as a flight level. In this case
it is left as a default as it is not applicable.
5129N00028W005 is the ‘Centre point’ using degrees and minutes followed by a radius
of influence. In this case the default value of 5NM has been applied based on the
aerodrome ARP. A default radius of 999 is applied for NOTAM that cannot be associated
to a specific area and for those that affect the whole FIR.
Position (Where)
A) EGLL is the ICAO code of the aerodrome (Heathrow). While it is possible to insert
more than one FIR into this field, it is only possible to enter one Aerodrome. This means
that separate NOTAM are required if the impact is on two or more aerodromes.
Effective from (Begins)
B) 1408231500 is the Date/time group in UTC when the NOTAM becomes effective.
Year, Month, Day, Time. NOTAM used to replace or cancel other NOTAM can only be
issued With Immediate Effect (WIE) and cannot have a future effective (start) date.
Effective until (Finishes)
C) 1409310500 is the Date/time group in UTC when the NOTAM ceases to be effective.
Temporary NOTAM shall exist no longer than 90 days.
Where an expiry date/time can only be estimated EST may be included in Field C for
temporary NOTAM. Sponsors shall take action to cancel or replace the NOTAM before the
EST expiry time.
Planned Schedule (Optional)
D) 1500-1630, 0430-0500 this provides the opportunity to describe a schedule of
events within the effective date of the NOTAM. This is particularly useful for events that
take place over a period of days or weeks. Irregular schedules that do not meet certain
criteria will have to be described in the plain language part of the NOTAM
Plain Language (Free-text)
E) RWY 09R/27L CLOSED DUE WIP is the textual part of the NOTAM indicating that
Runway 09/27 is closed due to work in progress.
This item describes the ‘subject’ and ‘condition’ and is probably the most important part
of the message. The information should be explicit giving the reader the ability to quickly
assess the impact to their operation.
Start with a ‘headline’ to describe the subject and event e.g. RWY…CLOSED, TWY… WIP,
DANGER AREA … ACTIVATED, FREQUENCY … U/S. After which supplemental information
may be considered to describe the impact.
Avoid information that may be considered as ‘nice to have’ or complementary. Use
internationally recognised abbreviations (as per ICAO Doc 8400) unless their use creates
misunderstanding. A list of abbreviations is available in the General (GEN) section of the
AIP but note that National abbreviations (in italics) cannot be used for NOTAM.
10th August 2023

UK NOTAM GUIDANCE MATERIAL
Use of Coordinates
If there is a requirement to describe an area or polygon, the provision of coordinates
Degrees/Minutes/Seconds shall be used e.g. 521049N 0012035W. When describing an
area repeat the first coordinate in full to close the polygon.
Supplementary Information
The judgment needed to assess the extent of information required in a NOTAM can be
problematical. Too much information can serve to overwhelm the reader, whereas not
enough information will fail to provide them with an opportunity to assess the impact on
the operation.
Guidance in composing the text of a NOTAM can be obtained by contacting the NOTAM
Office directly to establish that the proposal clearly captures the objective.
Vertical Parameters
Fields F & G describe lower and upper limits. They are not used for Aerodrome NOTAM
scoped A; however, they are used for airspace notifications such as navigation warnings,
airspace reservations and Danger Area activities. The sponsor should ensure that
appropriate values are included in the NOTAM proposal e.g. FL090, 3000FT AMSL.
When the values in Fields F and G are expressed as a flight level (FL) or altitude (AMSL)
the associated FL values will also be applied in the Q Line. It is recommended that the
use of AGL is avoided in fields F & G, as it demands a calculation based upon the highest
terrain elevation for the region or FIR.
3.4 Transmission
NOTAM are automatically transmitted by AFTN to the distribution list managed by UK
NOF. Requests to amend the AFTN distribution lists used for NOTAM shall be directed to
the UK NOF using email address: [email protected].

Introduction This guidance has been created with the objective of supporting NOTAM sponsors in the preparation and submission phase to enable clear and concise provision of information to its readers. 1. 1 NOTAM Definition - (ICAO Annex 15) “A notice distributed by means of telecommunication containing information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to personnel concerned with flight operations. ” 1. 2 NOTAM Proliferation Statistics indicate that the number of NOTAM being distributed globally continues to escalate. The UK NOTAM office alone transmits in excess of 5558 NOTAM every month. As the complexities around services and facilities increase, so the requirement to deliver consistent information in an accurate and timely manner becomes vital. 1. 3 NOTAM Sponsorship In practical terms planned changes to facilities and services affecting the safe operation of aircraft should be notified to AIS giving as much notice as possible"

Consequently, a NOTAM proposal received by NOF from an aerodrome notifying obstacles can therefore be regarded as necessary for the purposes of aerodrome safeguarding. A NOTAM proposal received by NOF from an aerodrome must include – i. Type of obstacle. ii. Obstacle position and location, represented by geographical coordinates in degrees, minutes, seconds and tenths of seconds if required for accuracy. iii. Obstacle height in AGL and AMSL in feet iv. Obstacle marking, and type and colour of obstacle lighting (if any).

Avoid sending a NOTAM proposal that describes a multitude of disconnected subjects. The information must be clear and unambiguous giving the reader the ability to quickly assess the impact. Be mindful that the information will be delivered to an international audience where a great many recipients will not have English as their primary language.

Introduction This guidance has been created with the objective of supporting NOTAM sponsors in the preparation and submission phase to enable clear and concise provision of information to its readers. 1. 1 NOTAM Definition - (ICAO Annex 15) “A notice distributed by means of telecommunication containing information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to personnel concerned with flight operations. ” 1. 2 NOTAM Proliferation Statistics indicate that the number of NOTAM being distributed globally continues to escalate. The UK NOTAM office alone transmits in excess of 5558 NOTAM every month. As the complexities around services and facilities increase, so the requirement to deliver consistent information in an accurate and timely manner becomes vital. 1. 3 NOTAM Sponsorship In practical terms planned changes to facilities and services affecting the safe operation of aircraft should be notified to AIS giving as much notice as possible",

If AFTN is not available due to connectivity issues, then sponsors can email their proposal to notam. proposals@nats. co. uk using the NOTAM form at the following address: https://nats-uk. ead-it. com/cms-nats/opencms/en/NOTAM/#NOTAM_REQUEST_FORM Authorised sponsors that do not have an AFPEX account can sign up for a free NOTAM only account.

One NOTAM will be scoped as AE (Aerodrome and En-route), any additional NOTAM will be scoped A to identify other affected aerodrome/s. 2. 7 New/Temporary obstacles regarding the safe operation of aircraft All obstacles over 100 m (328ft) AGL are to be notified to the CAA. It is mandatory to notify the CAA of any obstacle of a height of 100m AGL and more. This requirement applies regardless of where the obstacle is located. Obstacles within aerodrome notification areas should be notified to the relevant aerodrome operator. Occasionally unverified reports are received from the public describing the presence of an obstacle.

" Organisers of such events are required to contact the CAA giving as much notice as possible. An individual assessment of each activity is conducted by an Airspace Specialist resulting in an appropriate method of notification on behalf of the organiser. Note: More information about event and obstacle notification can be found here: https://www. caa. co. uk/Commercial-industry/Airspace/Event-and-obstacle- notification/Event-and-obstacle-notification/ 2. 2 ‘Out-of-Hours’ Nav Warnings a) When the NOF receives a NOTAM for a Nav Warning request outside the CAA AR operational hours which has not been de-conflicted by CAA AR, NOF shall inform the sponsor about the NOTAM policy and advise the sponsor to contact CAA AR, the NOF should also inform CAA AR about the request. b) However where there is an urgent need to distribute a NOTAM for a Nav Warning to ensure safety of operations and when contact with CAA AR is not possible before the start of the activity (or occurrence of any other hazard to air navigation) and the sponsor has confirmed that the activity (or hazard) cannot be cancelled (or hazard eliminated) or delayed, a NOTAM should be published. Both CAA AR and CAA AIMR should be notified via email including a copy of the NOTAM (marked HIGH IMPORTANCE). CAA AR shall de- conflict such notifications at the earliest opportunity",
" only routinely be promulgated by NOTAM if the display falls within the area defined in Annex B to CAP 736. NOTAM action may also be taken if the display lies inside CAS or close to known low-level aircraft routes. 3. NOTAM 3. 1 The AFTN NOTAM Proposal As a general principle, each submission should deal with only one subject and one condition. Avoid sending a NOTAM proposal that describes a multitude of disconnected subjects. The information must be clear and unambiguous giving the reader the ability to quickly assess the impact. Be mindful that the information will be delivered to an international audience where a great many recipients will not have English as their primary language. All proposals should be transmitted to the UK NOF using the AFTN address EUECYIYP. This address is used by those NOF Offices that have adopted the European AIS Database (EAD) service for broadcasting their NOTAM. When composing the NOTAM Proposal, it is important that the first line of text is constructed according to an explicit format. The message is to be prefixed with the type 10th August 2023 7 of 13 \fUK NOTAM GUIDANCE MATERIAL of NOTAM i. e. NOTAMN to announce a new NOTAM, NOTAMR to replace a current NOTAM and NOTAMC to cancel a NOTAM. The use of PROPOSAL EGGN in the first line of text is compulsory and signifies that the message is for the attention of the UK NOTAM Office. After the first line, the message can take any format. The closer the content is aligned to the NOTAM format the quicker AIS will be able to",
"AM Plain Language (Free-text) E) RWY 09R/27L CLOSED DUE WIP is the textual part of the NOTAM indicating that Runway 09/27 is closed due to work in progress. This item describes the ‘subject’ and ‘condition’ and is probably the most important part of the message. The information should be explicit giving the reader the ability to quickly assess the impact to their operation. Start with a ‘headline’ to describe the subject and event e. g. RWY…CLOSED, TWY… WIP, DANGER AREA … ACTIVATED, FREQUENCY … U/S. After which supplemental information may be considered to describe the impact. Avoid information that may be considered as ‘nice to have’ or complementary. Use internationally recognised abbreviations (as per ICAO Doc 8400) unless their use creates misunderstanding. A list of abbreviations is available in the General (GEN) section of the AIP but note that National abbreviations (in italics) cannot be used for NOTAM. 10th August 2023 9 of 13 \fUK NOTAM GUIDANCE MATERIAL Use of Coordinates If there is a requirement to describe an area or polygon, the provision of coordinates Degrees/Minutes/Seconds shall be used e. g. 521049N 0012035W. When describing an area repeat the first coordinate in full to close the polygon. Supplementary Information The judgment needed to assess the extent of information required in a NOTAM can be problematical. Too much information can serve to overwhelm the reader, whereas not enough information will fail to provide them with an opportunity to assess the impact on the operation. Guidance in composing the text of a NOTAM can be obtained by contacting the NOTAM Office directly to",
" establish that the proposal clearly captures the objective. Vertical Parameters Fields F & G describe lower and upper limits. They are not used for Aerodrome NOTAM scoped A; however, they are used for airspace notifications such as navigation warnings, airspace reservations and Danger Area activities. The sponsor should ensure that appropriate values are included in the NOTAM proposal e. g. FL090, 3000FT AMSL. When the values in Fields F and G are expressed as a flight level (FL) or altitude (AMSL) the associated FL values will also be applied in the Q Line. It is recommended that the use of AGL is avoided in fields F & G, as it demands a calculation based upon the highest terrain elevation for the region or FIR. 3. 4 Transmission NOTAM are automatically transmitted by AFTN to the distribution list managed by UK NOF. Requests to amend the AFTN distribution lists used for NOTAM shall be directed to the UK NOF using email address: notam. proposals@nats. co. uk. 4.

" Requests and publishing other aeronautical information products can be found here: https://nats-uk. ead-it. com/cms- nats/opencms/en/Publications/submit-change-request/ Do not use AFTN to sponsor a Permanent NOTAM, they should be submitted via Aurora Data Originators Portal as part of the AIP Change Request. However, during out-of-hours, if a Perm change is imminent and critical to Flight Safety then a temporary NOTAM may be issued for a maximum of 7 days. The sponsor must submit an AIP CR as soon as possible but within 7 days. 1. 8 Regulatory approvals Compliance with regulatory approval requirements shall not inhibit the urgent distribution of aeronautical information necessary to ensure the safety of flight. Regulatory approvals of items submitted via Aurora Data Originators Portal are sent to the CAA directly by the AIS. Notifying the CAA about any temporary changes promulgated via NOTAM, to data items requiring regulatory approval, remain the responsibility of the Sponsor but UK NOF may be asked for assistance or coordination. 10th August 2023 3 of 13 \fUK NOTAM GUIDANCE MATERIAL When an aerodrome wishes to temporarily increase their declared distance, eg special events, the AD Operator must obtain prior approval from (SRG) before a NOTAM is proposed. Note: More information about regulatory approvals and notifications process is provided in CAP 1054. 1. 9 Permanent Changes to the UK Mil AIP Military units can issue permanent NOTAM via AFTN; however, the sponsor is to advise No 1 AIDU as soon as possible to ensure the UK Mil AIP is updated",

Consequently, a NOTAM proposal received by NOF from an aerodrome notifying obstacles can therefore be regarded as necessary for the purposes of aerodrome safeguarding. A NOTAM proposal received by NOF from an aerodrome must include – i. Type of obstacle. ii. Obstacle position and location, represented by geographical coordinates in degrees, minutes, seconds and tenths of seconds if required for accuracy. iii. Obstacle height in AGL and AMSL in feet iv. Obstacle marking, and type and colour of obstacle lighting (if any). (NOF will defer to proposer if any of these criteria are missing. ) The NOF will promulgate the NOTAM as scope ‘AE’ thereby ensuring the information is included in an aerodrome PIB and En-route PIB. CAA/AR section propose ‘N’ series (En-route) NOTAM for obstacles over 100m/328ft AGL and not affecting aerodrome operations that are notified to CAA by owners/operators.

This includes: interruption or return to operation, change of frequencies, change in notified hours of service, change of identification, change of orientation (directional aids), change of location, power increase or decrease amounting to 50 per cent or more, change in broadcast schedules or contents, or irregularity or unreliability of operation of any radio navigation and air-ground communication services or limitations of relay stations including operational impact, affected service, frequency and area; d) Unavailability of back-up and secondary systems, having a direct operational impact. e) Establishment, withdrawal or significant changes to visual aids. 10th August 2023 1 of 13 \fUK NOTAM GUIDANCE MATERIAL f) Interruption of or return to operation of major components",
". c) It is the Sponsor’s responsibility to notify AR in advance of any planned unusual aerial activities taking place outside an ATZ to ensure de-confliction of the airspace. Publication of a NOTAM cannot be considered as a means of notifying the CAA about the activity and must not be considered as approval for the activity. d) CAA AR Operational hours for the purpose of the arrangements in this policy are: a. Mon – Fri 08:30 – 16:30 (excluding UK public bank holidays and notified closed periods). e) The above policy is valid for new NOTAM requests as well as changes and cancellations of published NOTAM for Nav Warnings unless agreed otherwise between CAA AR, NOF and the sponsor(s). 2. 3 Unlicensed Aerodromes Unlicensed aerodromes with or without an ICAO 4-letter location indicator are able to propose NOTAM for safety related subjects for facilities and services at their aerodrome. Such information will be issued as an E Series NOTAM. Unlicensed aerodromes with or without an AFTN that have unusual aerial activities shall be brought to the attention of CAA Airspace Regulation who will consider an H series NOTAM. 2. 4 En-route Obstacles The ENR 5. 4 section of the UK AIP contains a list of all known obstacles in the UK FIRs above 100m/328ft AGL. The information includes unique references, obstacle types and whether lighting is known to be fitted or not.
