The Aeronautical Information Publication (AIP) is the basic manual on aeronautical information.

It contains information of a lasting character and long-term temporary changes pertinent to the services, facilities, regulations and procedures that affect air operations performed at Spanish airports and in the Spanish airspace. Is divided into three parts:

• General (GEN): five sections containing information of an administrative and explanatory nature.
• En-route (ENR): seven sections containing information concerning the airspace and its use: ATS procedures and rules, airspace description, etc.
• Aerodromes (AD): four sections containing information on aerodromes/heliports in the Spanish territory and their use: geographical and administrative data, physical characteristics, associated cartography, etc.

All of the information supplied by the AIP is kept updated via regular amendments, AIRAC (Aeronautical Information Regulation and Control) amendments, supplements and NOTAMs.

Regular amendments

Contain small changes and editorial corrections as well as information of a lasting character previously distributed in NOTAMs or supplements and requiring insertion in the AIP. Published monthly, usually on the date an AIRAC cycle begins.

The AIP is updated on the website on the day it is published, in accordance with the content of the amendment issued on that date. Changes are indicated via the insertion of an arrow in the left-hand margin of the page at the place where the amendment is made.

This is the section where you can consult the cover pages that accompany the regular amendments.

AIRAC amendments

AIRAC amendments (AMDT AIRAC) contain predictable information of a lasting nature that is important for air navigation and/or airport operations. Changes become effective after they are published.

They are published in accordance with the regulated AIRAC publication system, based on the distribution of information in line with a schedule of effective dates at 28-day intervals, predetermined and agreed on internationally.

AIRAC amendments have a green cover and pages that must be included in the AIP on the effective date. The cover indicates:

• The AMDT AIRAC number.
• The date (day and month) of publication.
• The AIRAC effective date of the information.
• A brief description of the changes included in the amendment and a list indicating the pages to be inserted and/or replaced in the AIP on the effective date.
• A list of NOTAMs, SUPs and/or AICs that must be cancelled with the inclusion of the amendment.

Published AIRAC amendments can be viewed before they go into effect, allowing you to make a plan that takes them into account.  Once in force, amendments are included in the AIP on the website.

Supplements

Supplements complement or vary the information contained in the AIP and contain temporary information that requires extensive texts and/or explanatory graphics. There are two types of supplements:

• Regular Supplement (REGULAR SUP): published at regular intervals whenever there is information available and containing information which comes into effect on specific dates clearly marked on each SUP. They are published on yellow pages and comprise:
  • The REGULAR SUP number.
  • The date (day and month) of publication.
  • The effective date of the information.
  • The part of the AIP affected by the incident.
  • The validity period.
  • A detailed description of the incident.
  • A list of NOTAMs, SUPs and/or AICs that must be cancelled with the inclusion of the SUP.
• AIRAC Supplement (AIRAC SUP): in addition to the main characteristics of any SUP, an AIRAC SUP contains predictable, temporary information that is important for air navigation and/or airport operations, appropriate for publication through the AIRAC system and as such, in accordance with the specific timetable for entry into effect. AIR SUPs are published entirely on pink paper and comprise:
  • The AIRAC SUP number.
  • The date (day and month) of publication.
  • The AIRAC effective date of the information.
  • The validity period.
  • The part of the AIP affected by the incident.
  • A detailed description of the incident.
  • A list of NOTAMs, SUPs and/or AICs that must be cancelled with the inclusion of the AIRAC SUP.

Circulars

Air operation information exists which is not included in the AIP or distributed by NOTAM or supplement. This information is published in Aeronautical Information Circulars (AICs).

AICs mainly contain administrative or explanatory information or advice that could affect operations in the long term.  In general, AICs usually provide advance information on changes in legislation or regulations, the implementation of new facilities or changes in publication procedures, etc.

There are two series of circulars, depending on the level they affect:

• National (published only in Spanish).
• International.
