AIS Operation Section provides aeronautical information necessary for the safety, regularity and efficiency of international and national air navigation in the Philippine Flight Information Region (FIR). The aeronautical information is provided in the form of an Integrated Aeronautical Information Package consisting of the following elements:
Aeronautical Information Publication (AIP)
Amendment Service to the AIP (AIP AMDT)
Supplement to the AIP (AIP SUP)
Aeronautical Information Circulars (AIC)
Checklists and NOTAM Summaries
Aeronautical Information Publication (AIP)
The AIP is the basic aeronautical information document published for the Republic of the Philippines that contains permanent information essential to air navigation within the Philippine FIR. AIP is made up of three parts, namely General (GEN), En-route (ENR) and Aerodromes (AD).It contains information of a lasting character essential to air navigation and it is updated by a regular amendment service of reprinted pages based on an AIRAC cycle.
Amendment Service to the AIP (AIP AMDT)
Amendments to the AIP together with checklists are made by means of replacements sheets. Regular AIP Amendment (AIP AMDT) issued in accordance with the established regular interval and identified by the cover sheet, incorporates permanent changes into the AIP on the indicated effective date.
A brief description of the subjects affected by the amendment is given on the AIP Amendment cover sheet. New information included on the reprinted AIP pages is annotated or identified by a vertical line in the left margin (or immediately to the left) of the change/addition.
Each AIP page and each AIP replacement page introduced by an amendment, including the amendment cover sheet, are dated. The date consists of the day, month (by name) and year of the effective date of the information. Each AIP amendment cover sheet includes references to the serial number of those elements, if any, of the Integrated Aeronautical Information Package which had been incorporated in the AIP by the amendment and is consequently cancelled.
Each AIP AMDT is allocated with a serial number, which is consecutive and based on the calendar year. The year, indicated by two digits, is a part of the serial number of the amendment, e.g. AIP AMDT 041/11.
A checklist of AIP pages containing page number/chart title and the publication or effective date (day, month by name and year) of the information is reissued which each amendment and is an integral part of the AIP.
Supplement to the AIP (AIP SUP)
Temporary changes of long duration (three months and longer) and information of short duration which consist 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.
AIP Supplements are placed at the beginning of the AIP. Supplements are published on colored paper to be conspicuous and to stand out from the rest of the AIP. Each AIP Supplement (regular or AIRAC) is allocated a serial number, which is consecutive and based on the calendar year, i.e. AIP SUP 1/01.
An AIP Supplement is kept in the AIP 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.
The checklist of AIP Supplements currently in force is issued in the monthly printed plain language summary of NOTAM in force.
Aeronautical Information Circulars (AIC)
The Aeronautical Information Circular (AIC) contain information on the long-term forecast of any major change in legislation, regulations, procedures or facilities; information of purely explanatory or advisory nature liable to affect flight safety; and information or notification of explanatory or advisory nature concerning technical, legislative or purely administrative matters.
Each AIC is numbered consecutively on a calendar year basis. The year, indicated by two digits, is a part of the serial number of the AIC; e.g. AIC 1/01. A checklist of AIC currently in force is issued as an AIC once a year.
Checklist and Summary of NOTAM
A checklist of valid NOTAM is issued monthly via AFTN. The checklist is followed by a printed summary of NOTAM distributed by mail to all recipients of the Integrated Aeronautical Information Package. It contains a plain language (in English) presentation of the valid NOTAM and information about the number of the latest issued AIP AMDT, AIP SUP and AIC as well as the numbers of the elements issued under the AIRAC that will become effective or, if none, the NIL AIRAC notification.
