The Aeronautical Information Services are responsible for the collection and dissemination of information for the entire territory of Portugal and for airspace over the high seas encompassed by Lisboa FIR (LPPC) and Santa Maria FIR (LPPO).

3.1.3   Aeronautical publications

3.1 Aeronautical information is provided in the form of Aeronautical Information Products in a standardized presentation of the following elements:

  • Aeronautical Information Publication (AIP);
  • Visual Flight Rules Manual (VFR Manual);
  • Amendment service to the AIP (AIP AMDT);
  • Amendment service to the VFR Manual;
  • Supplement to the AIP (AIP SUP);
  • Supplements to the VFR Manual;
  • Aeronautical Information Circulars (AIC);
  • NOTAM including NOTAM checklist; and
  • Aeronautical Charts.

3.2 Aeronautical Information Publication (AIP)

The AIP is the basic aviation document intended primarily to satisfy international requirements for the exchange of permanent aeronautical information and long duration temporary changes essential for air navigation.The AIP of Portugal is available in electronic form (eAIP) for use in international and domestic operations. It is issued in English only and available on the AIS website https://ais.nav.pt/

3.3 Visual Flight Rules Manual (VFR Manual)

The VFR Manual contains all relevant information for VFR traffic and is published in bilingual text in Portuguese and English. It is updated by means of VFR Manual amendments and/or VFR Manual Supplements.The VFR Manual is available in electronic format (ISO file).

3.4 Amendment service to the AIP (AIP AMDT)

AIP Amendments contain permanent changes to the AIP.Amendments to the eAIP are published by reissuing the eAIP. Each eAIP issue contains:

  • The complete AIP for the relevant effective date;
  • The AIRAC AIP AMDT for the relevant effective date;
  • Published AIP Supplements and Aeronautical Information Circulars (AIC) as is on the publication date of eAIP.

eAIP sections have a check box in the top right corner, which allows changes to be displayed graphically. The changes in the eAIP are identified by a pink background, and removed text is struck though with a horizontal line. In the PDF version changes on text pages are identified by a vertical line in the left margin. On charts, change description is indicated on the margin.

Two different types of Amendments are produced:

  • AIRAC AIP Amendment (AIRAC AIP AMDT), issued in accordance with the AIRAC system and identified by the acronym — AIRAC, incorporates operationally significant permanent changes into the AIP on the indicated AIRAC effective date.
  • Regular AIP Amendment (AIP AMDT), issued in accordance with the established regular interval, incorporates permanent changes into the AIP on the indicated publication date.

A brief description of the subjects affected by the amendment is given on the AIP Amendment cover sheet. Each AIP page and AIP replacement page introduced by an amendment is dated including the amendment cover sheet. The date consists of the day, month (by name) and year of the publication date (regular AIP AMDT) or of the AIRAC effective date) of the information (AIRAC AIP AMDT). Each AIP amendment cover sheet includes references to the serial number of those elements, if any, of the Aeronautical Information Products which have been incorporated in the AIP by the amendment and are consequently cancelled.

Each AIP AMDT and each AIRAC AIP AMDT are allocated separate serial numbers, which are consecutive for the AIP AMDT and based on the calendar year for the AIRAC AIP AMDT. The year, indicated by two digits, is a part of the serial number of the amendment, e.g. AIP AMDT 025/20, AIRAC AIP AMDT 001/20.

A checklist of AIP pages containing page number/chart title and the publication or effective date of the information (day, month by name and year) is reissued with each amendment and is an integral part of the AIP (ref. GEN 0.4).

3.5 Amendment service to the VFR Manual

The VFR Manual Amendments are published only as Regular Amendments and contain information of both operational and non-operational significance. Amendments are published with the necessary regularity to keep the VFR Manual up-to-date.

The amendment numbering is consecutive.

3.6 Supplements to the AIP (AIP SUP)

Temporary changes of long duration (three months or longer) and information of short duration, which consists of extensive text and/or graphics, supplementing the permanent information contained in the AIP, are published as AIP Supplements (AIP SUP). Operationally significant temporary changes to the AIP are published in accordance with the AIRAC system and its established effective dates and are identified clearly by the acronym AIRAC AIP SUP.

Each AIP Supplement (regular or AIRAC) shall be allocated a serial number which shall be consecutive and based on the calendar year, e.g. AIP SUP 004/20; AIRAC AIP SUP 0051/20.

An AIP Supplement remains valid as long as all or some of its contents remain valid. The period of validity of the information contained in the AIP Supplement will normally be given in the supplement itself. Alternatively, NOTAM may be used to indicate changes to the period of validity or cancellation of the supplement.

AIP Supplements, which are published in the period between the issue of two consecutive eAIP AMDT, are made available on AIS website https://www.nav.pt/ais and subscribers notified by e-mail.

The checklist of AIP Supplements currently in force is issued as part of the monthly NOTAM checklist Series A and published in the AIP (GEN-0.3).

3.1.4   AIRAC system

4.1 In order to control and regulate the operationally significant changes requiring amendments to charts, route-manuals etc., such changes, whenever possible, will be issued on predetermined dates according to the AIRAC System. This type of information will be published as an AIRAC AIP AMDT or an AIRAC AIP SUP. If an AIRAC AMDT or SUP cannot be produced due to lack of time, a NOTAM will be issued. Such NOTAM will be incorporated in an AMDT or SUP.

4.2 The table below indicates AIRAC effective dates for the coming years. AIRAC information is issued so that the information will be receive by the user not later than 28 days, and for major changes not later than 56 days, before the effective date. At AIRAC effective date, a trigger NOTAM will be issued giving a brief description of the contents, effective date and reference number of the AIRAC AIP AMDT or AIRAC AIP SUP that will become effective on that date. Trigger NOTAM will remain in force as a reminder in the PIB for a period of 14 days.

If no information has been submitted for publication at the AIRAC date, a NIL notification will be included in the NOTAM checklist, at least 28 days in advance of the AIRAC date concerned.The predetermined effective dates of the AIRAC system are as follows:
