Background: The Air Navigation Plans (ANP)

Air navigation plans set forth in detail the facilities, services and procedures required for international air navigation within a specified area. Such plans contain recommendations that governments can follow in programming the provision of their air navigation facilities and services, with the assurance that facilities and services furnished in accordance with the plan will form with those of other States an integrated system adequate for the foreseeable future.
Regional Air Navigation Plans (ANPs) set forth in detail the facilities, services and procedures required for international air navigation within a specified geographical area.
The development of these regional plans is undertaken by ICAO’s six planning and implementation regional groups (PIRGs) in coordination with States and supported by ICAO’s Regional Offices and the Air Navigation Bureau.

How to improve the ANP and process

In February 1997, the Council decided that the ANPs should be published in two volumes, a basic ANP as volume I and facilities and services implementation document (FASID) as volume II.
The first volume of this document, the Basic ANP, contains general planning criteria, implementation guidelines and stable plan elements. The second volume, the FASID, sets forth in general terms the facilities, services and procedures required for international air navigation within a specified area.
The intent was to simplify amendment process to ensure currency of information. Amendments to Basic ANP, the stable document, require a time-consuming approval process by the governing bodies whereas the FASID requires frequent updates through coordination within the Secretariat. Should an amendment to either volume of the ANP be contentious, the issue would be brought to the attention of the ANC Council as appropriate.
Effective July 2011, the amendment process was automated to further reduce the time reviewed within ICAO headquarters.

Moving ANPs online: eANP

But despite all these improvements, the challenge remained to keep the paper-based Regional ANPs updated.

To reduce time to process the ANPs, duplication, and rework, it is necessary to transition the paper based ANPs to an online format. To address this issue, an online format of the Regional ANPs, called eANPs, has been launched.
However, this evolution should allow the air navigation planner to continue to use the data or tools for their daily work. Consequently, ICAO has developed a plan to transition to the eANP by using it as an alternative to the paper-based ANPs.
All PIRGs upon review of the online system, or components thereof, are encouraged to transition any part of the ANPs that contains the same information to the electronic format.

eANP Today

The eANP continues to develop and is the first version is expected to be completed in time for the Twelfth Air Navigation Conference this November, 2012.
As the data, tables, and platform are established, the eANP will evolve to include the following:
  • Data related to ICAO Document 7910, Location Indicators.
  • Data related to aerodromes and AIM.
  • Data related to MET is on the current online application
  • Charts using the Geographic Information System (GIS)

Benefits of the eANP

  • It is a user-friendly, robust, web-based planning and editing tool to ensure centralization and currency of data;
  • All partners share the data and can distribute new versions or updates quickly and easily;
  • The text and tables of ATS Routes of Volume I, the Basic ANP has been updated;
  • The FASID tables in Volume II are updated with a new format for all of the tables including CNS, AIM, AOP and MET.
  • These FASID tables have now been standardized and harmonized across all regions and aligned with ASBU methodology;  

Moving Forward

ICAO is progressing towards development of Regional e-ANPs for all the regions and will include Aviation System Block Upgrade (ASBU) methodology.


Beta versions of all applications to view data will be launched by June 2012.
