NOTAM templates proposals for volcanic ash events
SUMMARY
This document provides draft proposals of NOTAM templates related to the operational
impact and limited access of airspace and routes affected by volcanic ash, with reference to
the action agreed by the AISAIM Study Group/3 (Action agreed 9/3 Aeronautical information
dissemination related to volcanic ash.
The templates are developed with the purpose to create harmonisation in management of
NOTAM messages related to a volcano eruption, where enhancement in ICAO guidance
material for NOTAM creation was proposed to the Study Group.
The templates are providing a structured order of the information that shall be inserted in
item E). The structure of the free text will create a harmonised output of the NOTAM,
improving the readability of the message and processing of the data by the end user.
The proposed structure is taking into account the on-going progress in the digital NOTAM
developments, following the digital NOTAM Event Specification as developed by the
dedicated Focus Group.

CHAPTER 1 – Introduction
1.1
Purpose of document
As a consequence of the lessons learned by the European States AIS organisations
regarding the need for harmonisation in management of NOTAM related to a volcano
eruption events, the ICAO AISAIM Study group proposed that the ICAO guidance material be
enhanced to include examples of a series of NOTAM related to the operational impact and
limited access of airspace and routes affected by volcanic ash. The templates are intended
to assist States in expediting the process of originating and issuing NOTAM for the different
phases of volcanic activity, in order to harmonise the output in the messages and enhance
the usability of the aeronautical information for the users.
This document provides draft proposals of a series of NOTAM templates and examples, for
consideration by the AISAIM Study Group for inclusion in ICAO AIS provisions.
1.2
Structure of document
The document provides guidance for the full range of NOTAM examples required for
warnings of volcanic activity and restrictions on airspace, airports and en route operations as
a result of volcanic activity, including recommended NOTAM codes.
The templates are as closely as possible based on the structured data format of the digital
NOTAM specification and defined event scenarios.
Chapter 2 provides an overview of the templates and NOTAM examples that are proposed to
be moved forward for inclusion in ICAO Doc 8126.
Chapter 3 provides a detailed description of the structure of the NOTAM templates and
detailed instructions for how to insert the information in the templates, and again NOTAM
examples.
The NOTAM templates covers the following subjects:





1.3
airspace warnings
airspace restrictions
aerodrome/heliport closure
route portion restriction/flight levels
on-ground volcanic ash on the movement area
Validation of NOTAM templates
The NOTAM templates created for navigation warnings and temporary airspace restrictions
in version v0.2 of the document were included in the exercise directives of the ICAO
EUR/NAT Volcanic Exercise VOLCEX 11-01, 13-14 April 2011. Dissemination and reception
of volcanic ash related NOTAM were part of the exercise objectives to ensure that NOTAM
was issued in accordance with the provided templates by the participating States’ NOTAM

NOTAM templates proposals for volcanic ash events
Offices. Taking into account the evaluation of the effectiveness of the NOTAM issued during
exercise VOLCEX 11-01, the templates were updated in v 0.3, as well as updates to reflect
the terminology used by the International Volcanic Ash Task Force (IVATF) in the delivery
“ATM Volcanic Ash Contingency Plan Template”, for areas of contamination and phases of a
volcanic event.
Further evaluation of the updated templates in this version will be proposed for the ICAO
EUR/NAT VOLCEX, planned for April 2013.

CHAPTER 2 – NOTAM Templates
2.1
General
2.1.1
Structure of NOTAM content
For each subject a short description is describing for which situation the templates can be
used. It follows by a description of the structure of the NOTAM text, providing the sequence
of the free text information to be inserted in item E). The structure follows as closely as
possible the information elements that are defined for a dedicated digital NOTAM event
scenario.
A detailed instruction of how to insert the information following the structure is provided per
event in Chapter 3.
2.1.2
Filling instructions and NOTAM codes
The NOTAM examples include some instructions in completion of the qualifier line, the
recommended NOTAM code and instruction in how to describe a published airspace in item
E).
2.2
Navigation warnings – Warnings (W)
2.2.1
Type of operational impact/event
These templates apply for the issuance of navigation warnings for volcanic activity providing
as precise information as is available regarding the activity, for the pre-eruption, start of
eruption, ongoing eruption and recovery phases.
The examples cover elements such as the name and geographical position of the volcano,
alert code indicating the activity, the horizontal extend and base/top of reported ash cloud of
operationally significance, forecast direction of movement of the ash cloud and any
operationally significant information additional to the foregoing.

**) Definition of the area should be done by radius/circle or coordinates only. Definition of
airspace by the use of geographical or administrative features such as State borders, rivers,
sea shores etc) is not supported by the digital NOTAM event scenario and is therefore not
recommended. If operational necessary, this can be defined by providing a simplified
polygon larger than the area and excluding a neighbouring FIR, for example.
Coordinates defining the lateral limits of the area (polygon) should be enumerated in
clockwise order, each point separated by space-hyphen-space. The last and the first points
of the list shall be the same.

Recovery phase
NOTAMC shall be issued cancelling the active NOTAM and a new NOTAM (NOTAMN) shall
be promulgated to update the situation for volcanic ash as soon as the volcano has reverted
to its pre-eruptive status, no further eruptions are expected and no ash cloud is detectable or
reported from the FIR concerned.

Airport /Heliport closure [ad.cls]

Template
The following production rule defines the information elements that are used in order to
compose the text in item E in the NOTAM that announces the airport/heliport closure due to
volcanic ash contamination. For Digital NOTAM encoding, this is supported by the [AD.CLS]
scenario.
Although a few items are used for the event of volcanic ash contamination, for completeness
or the template, all items and explanations defined for the digital NOTAM encoding for
airport/heliport closure are included.
In the NOTAM examples, only the items needed are used. After the closure reason which is
always “DUE TO VOLCANIC ASH CONTAMINATION”, all other items can be skipped to go
directly to “note”, if such exists.
