MANUAL OF STANDARDS FOR AERODROMESFOREWORD

____________________________________________________________________________________________________

Version 0.1 (iii) May 2008

The Air Transportation Office of the Department of Transport and Communications isresponsible under the Civil Aeronautics Act (Republic Act No. 776) of the Republic ofthe Philippines, as amended) for the regulation of civil aviation in the Philippines.The Air Transportation Office (ATO) exercises regulatory oversight by, in part,developing and promulgating appropriate, clear and enforceable aviation safetystandards.

This Manual of Standards for Aerodromes (MOS) is one mechanism that ATO usesto meet the responsibilities of the Republic Act No. 776 to ensure safety regulation ofaerodrome matters. This MOS prescribes the detailed technical requirements(aerodrome safety standards) that have been determined to be necessary for

promoting and supporting aviation safety in general and aerodrome safety inparticular.

ICAO Annex 14 standards and recommended practices are contained in MOS,including the requirement that all certified aerodromes shall have a safetymanagement system. Aerodromes are to be certified where international operationsoccur, or where air transport operations are conducted by aircraft with a passengerseating capacity greater than 30. Certified aerodromes in Republic of thePhilippines are required to have an acceptable safety management system in place.Other smaller and less complex aerodromes may be registered with ATO and haveaeronautical data published in the AIP, but the need for an aerodrome safety

management system is not imposed. Standards are applicable to all aerodromesaccording to the type of aircraft operating at a particular location.

The MOS is referenced in Administrative Circular No. 139, Civil Aviation Regulationsgoverning aerodromes (AO 139). Users of this document should refer to theapplicable provisions of the Civil Aeronautics Act and AO 139, together with thismanual, to ascertain the requirements of, and the obligations imposed by, the civilaviation legislation in regard to aerodromes and aerodrome operators.

The responsibility for matters within this Manual of Standards is with the AirTransportation Office. Readers should forward advice of errors, inconsistencies or

suggestions for improvement to Executive Director at the address shown in thismanual.

MANUAL OF STANDARDS FOR AERODROMESCHAPTER 1 - General provisions.

_________________________________________________________________________________________________Version 0.1 (1 - 1) May 2008

Section 1.1 - General

1.1.1 Background

1.1.1.1 Aerodrome safety is a vital link in aviation safety. Providing adequate suitablefacilities and maintaining a safe operational environment for aircraft activitiespromotes aerodrome safety. By complying with the prescribed standards andprocedures and taking a pro-active safety management system approach,aerodrome operators can demonstrate that they have discharged their safetyobligations to the regulatory authority and to their clients who, ultimately, are thetraveling public.

1.1.1.2 This document, titled: Manual of Standards for Aerodromes, hereafter referredto as the MOS, is made pursuant to Administrative Order No.139 (AO 139). AO139 sets out the regulatory regime for aerodrome operators at aerodromes usedby aeroplanes conducting international and national air transport operations. Theaerodrome regulatory regime sets out when an aerodrome is to be certified or isto be registered, and this MOS contains the standards and operating proceduresfor certified and registered aerodromes used in air transport operations.

1.1.1.3 Aeroplanes with less than 10 passenger seats can conduct air transportoperations from aerodromes that are not certified or registered, provided thespecified facilities at those aerodromes are to the required standard, and theaircraft operator has, and makes available to crew members, the requisiteaerodrome information to enable the pilot to safely land and take off at suchuncertified aerodromes. Chapter 13 specifies the standards and procedures for

aerodromes intended only for small aeroplanes (those with less than 10passenger seats or in the case of freight operations, those not exceeding 5,700kg MTOW) conducting air transport or private operations.

1.1.1.4 Subject to published conditions of use, aerodromes and their associated facilitiesshall be kept continuously available for flight operations during published hours ofoperation, irrespective of weather conditions. Published conditions of use refersto aeronautical data promulgated by Philippines AIP or NOTAM or informationbroadcast by Air Traffic Control Units.

1.1.1.5 To assist aerodrome operators or potential operators, some general advice aboutspecifications, procedures and other information of an educational or advisory

nature may be issued from time to time by ATO in the form of Advisory Circulars.

1.1.1.6 This Manual of Aerodrome Standards, as referred to in AO 139.020(1) and asdefined therein, contains:(a) the requirements for the certification and registration of aerodromes; and(b) aerodrome standards, recommended practices and guidance materials

pertaining to the planning, operation and maintenance of aerodromeservices, facilities and equipment to be complied with by aerodromeoperators.

1.1.1.7 The scope of this manual is confined to the safety, regularity and efficiencyaspects of aerodrome facilities, equipment and operational procedures. It does

not cover such aspects as those related to aeronautical meteorology, theadministration of aerodrome finances and the servicing of passengers and cargo.


19/330


_________________________________________________________________________________________________Version 0.1 (1 - 2) May 2008

It also excludes air traffic services and aeronautical information services,although the coordination between those services and the aerodrome operatorhas been incorporated as an integral part of an aerodromes operations.

1.1.1.8 Aerodrome standards may change from time to time to meet identified safetyneeds, technological changes and changes in international standards andpractices. It is recognised that there may be difficulties and limitations inapplying new standards to existing aerodrome facilities and installations. Thisaspect is addressed in some detail in Chapter 2.

1.1.1.9 Standards are identified by the words must or shall. Appendices and tablesform part of the main document and have the same status as the primary text.This MOS may also require standards from other documents to be followed, andwhere this is so, the referred standards become part of this MOS.

1.1.1.10 Under particularly unusual circumstances, the application of a standard orprocedure may not be possible or necessary. Such a standard or procedure willbe phrased as if practicable, where physically practicable, where determinednecessary or similar words. Whilst such phrases may imply compliance is notmandatory, aerodrome operators are required to provide justification for non-compliance. The final decision as to the applicability of the standard to aparticular aerodrome facility or procedure rests with ATO.

1.1.1.11 Where there is flexibility in compliance with a specification, words such asshould or may are used. This does not mean that the specification can beignored, but it means that there is no need to seek ATO approval if an aerodrome

operator chooses to adopt an alternate means to achieve a similar outcome. Anysuch decision and the alternative means adopted are to be formally recorded andthe record maintained while the chosen means of conformance exists.

1.1.1.12 This MOS includes standards and procedural requirements relating to preventingthe inadvertent entry of animals and people to the movement area. Thosestandards and procedures are intended for aviation safety only. This MOS doesnot specifically address aviation security, i.e. the safeguarding against acts ofunlawful interference, and that subject matter is under separate regulation.

1.1.1.13 Where it is necessary or helpful to provide factual or background information,explanation or references, or to provide a means of achieving compliance,

information may be provided in the form of a note. A note does not constitutepart of a standard.

1.1.2 Terminology used in MOS

1.1.2.1 The status of other terms used jointly with standards and recommendedpractices in this MOS is explained as follows:a) Appendices

Appendices contain materials grouped separately for convenience andforming part of the standards or practices.

b) DefinitionsDefinitions do not have independent status but each one is an essential

part of each standard or practice in which the term is used, since a changein the meaning of the term would affect the specifications.


20/330


_________________________________________________________________________________________________Version 0.1 (1 - 3) May 2008

c) Tables and FiguresTables and Figures add to or illustrate a standard or practice, form part ofthe associated standard or practice and have the same status.

d) ForewordsForewords contain historical and explanatory material based on the actionof the ATO or ICAO.

e) IntroductionsIntroductions comprise explanatory material introduced at the beginning ofparts, chapters, or sections of this MOS to assist in the understanding ofthe application of the text, but do not constitute part of the standards orpractices.

f) NotesNotes are included in the text, where appropriate, to give factual informationor references bearing on the standards or practices in question, but do notconstitute part of the standards or practices.

g) AttachmentsAttachments comprise material supplementary to the standards orpractices, or are included as a guide to their application, but do notconstitute part of the standards or practices.

1.1.3 Document Set

1.1.3.1 The document hierarchy consists of:(a) Civil Aeronautics Act (Republic Act No. 776) of the Republic of the

Philippines, as amended(b) relevant Administrative Orders (AOs);

(b) the Manual of Standards (MOS); and(c) Advisory Circulars (ACs).

1.1.3.2 The Republic Act No. 776 establishes the broad intent of the government of theRepublic of the Philippines with regard to regulation of civil aviation.

1.1.3.3 AOs establish the regulatory framework rules (regulations) within which allservice providers must operate.

1.1.3.4 The MOS comprises specifications (standards) prescribed by ATO, for uniformapplication, determined to be necessary for the safety of air navigation.

1.1.3.5 In the event of any perceived disparity of meaning between MOS and AOs,primacy of intent is to be with the AOs.

1.1.3.6 Service providers must document internal actions (rules) in their own operationalmanuals, to ensure the compliance with, and maintenance of, relevant standards.

1.1.3.7 Advisory Circulars (AC) are intended explain elements of the regulatoryframework to participants in the aviation industry. Additionally an AC mayprovide recommendations and guidance to illustrate a means, but not necessarilythe only means, of complying with the requirements of aerodrome standards.AC may explain certain regulatory requirements by providing interpretive andexplanatory materials. As an AC provides only explanatory material, it is

expected that service providers will document relevant information in their ownoperational manuals to put into effect information drawn from Advisory Circular.

MANUAL OF STANDARDS FOR AERODROMESCHAPTER 2 - Application of standards to aerodromes.

_________________________________________________________________________________________________Version 0.1 (2 - 1) May 2008

Section 2.1: General

2.1.1 Legislative background and applicability

2.1.1.1 Civil Aviation Regulations relating to aeroplanes conducting air transportoperations stipulate that they shall conduct operations from aerodromes meetingthe requirements of AO 139.

2.1.1.2 AO 139.020 requires aerodrome operators to comply with standards andprocedures for aerodromes used in air transport operations. The standards andprocedures are set out in this document and are applicable to the extentappropriate for aerodrome operators.

2.1.1.3 Under Civil Aviation Regulations provisions, operators of aeroplanes with fewerthan 10 passenger seats may conduct air transport operations to aerodromes

that are not certified, provided specified aerodrome facilities and reportingarrangements meet appropriate standards. The aerodrome facilities standardsand procedures required are specified in this document.

2.1.2 Changes to standards

2.1.2.1 Standards are subject to change from time to time. In general, unless specificallydirected by ATO or subject to 2.1.2.3, existing aerodrome facilities do not need tobe immediately modified in accordance with new standards until the facility isreplaced or upgraded.

2.1.2.2 Unless otherwise directed by ATO, an existing facility that does not meet thestandard specified in this manual must continue to comply with the standard thatwas applicable to it.

2.1.2.3 At a certified or registeredaerodrome, an existing aerodrome facility that doesnot comply with this MOS must be identified and recorded, in the AerodromeManual where applicable. The data identified must include the date or periodwhen that facility was first introduced or last upgraded and an indication from theaerodrome operator of a plan or timescale to bring the facility in compliance withthe MOS. As part of a ATO audit, evidence to demonstrate efforts to implementa plan or timescale may be required.

2.1.2.4 This MOS applies to a new facility that is brought into operation, and to anexisting facility that is being replaced or improved. Subject to agreement with theATO, changes to an existing facility of a minor or partial nature may beexempted.

2.1.3 Aeronautical studies

2.1.3.1 Where an aerodrome operator is not able to comply with any standard orrecommended practice stipulated in MOS, an aeronautical study may beconducted to assess the impact of deviations from the standards andrecommended practices. The purpose of such studies is to present assessmentsof alternative means of ensuring the safety of aircraft operations, to estimate the

effectiveness of each alternative and to recommend procedures to compensatefor the deviation.


33/330


_________________________________________________________________________________________________Version 0.1 (2 - 2) May 2008

2.1.3.2 An aeronautical study is mostly frequently undertaken during the planning of anew airport or new airport facility, or during the certification of an existingaerodrome. It may also be carried out when aerodrome standards or

recommended practices cannot be met as a result of development.

2.1.3.3 An aeronautical study is a study of an aeronautical problem carried out by anaerodrome operator to identify possible solutions and select a solution that isacceptable without degrading safety. The ATO will review these studies on acase by case basis and determine the acceptability of each case to be satisfiedthat an equivalent level of safety will be attained.

2.1.3.4 Technical analysis must provide justification for a deviation on the grounds thatan equivalent level of safety can be attained by other means, and tht compliancewith the standard as it exists is impossible. It is generally applicable in situationswhere the cost of correcting a problem that violates a standard is excessive but

where the unsafe effects of the problem can be overcome by some procedural orother means which offer both practical and reasonable solutions.

2.1.3.5 In conducting a technical analysis, an aerodrome operator should draw upon thepractical experience and specialized knowledge of staff and/or consultants. Theaerodrome operator may also consult other specialists in relevant areas. Whenconsidering alternative procedures in the deviation approval process, it isessential to bear in mind the safety objective of the aerodrome certificationregulations and the applicable standards and recommended practices so that theintent of the regulations is not circumvented.

2.1.3.6 In some instances, the only reasonable means of providing an equivalent level ofsafety is to adopt suitable procedures and to require, as a condition ofcertification, that cautionary advice be published in the appropriate aeronauticalpublications.

2.1.3.7 The determination to require a published caution will be primarily dependent ontwo considerations:(a) a pilots need to be made aware of potentially hazardous conditions; and(b) the responsibility of the aerodrome operator to publish deviations from

standards and recommended practices that would otherwise be assumedunder a certified aerodrome status.

2.1.4 Exemptions to standards

2.1.4.1 When an aerodrome operator is unable to establish compliance with anystandard or practice specified in this MOS, the aerodrome operator may apply forexemption from the relevant standard or practice.

2.1.4.2 Application for an exemption must be supported, in writing, by cogent reasonsincluding any aeronautical study conducted and the associated results, and anindication of when compliance with the current standards can be expected.

2.1.4.3 Those standards which include phrases such as if practicable, wherephysically practicable, etc., still require an exemption to standards if an

aerodrome operator considers full compliance is not practicable.


34/330


_________________________________________________________________________________________________Version 0.1 (2 - 3) May 2008

2.1.4.4 ATO may exempt by notice in writing, after taking into account all safety-relatedaspects and operating circumstances, any aerodrome operator from compliancewith any standard or practice prescribed in this MOS.

2.1.4.5 Any exemption granted by ATO shall be subject to any condition or procedurespecified in the exemption instrument as being necessary in the interest ofsafety.

2.1.4.6 Exemptions to standards granted to an aerodrome operator must be recorded inthe Aerodrome Manual unless ATO approves an alternative recording process.The manual must contain details of the exemption, reason for the request, anyresultant limitations imposed, and similar relevant information.

2.1.4.7 An exemption granted to an existing facility continues to apply until its expirydate.

2.1.4.8 If an aerodrome manual is not required, a formal exemption instrument issued byATO must be retained by the aerodrome operator and produced on request.

2.1.5 Conflict with other standards

2.1.5.1 Compliance with the standards and procedures specified in this MOS does notabsolve aerodrome operators from obligations in respect of standards prescribedby other government or statutory authorities. Where another statutory standardconflicts with this MOS, the matter must be referred to ATO for resolution.

2.1.6 Using ICAO Aerodrome Reference Code

2.1.6.1 ATO has adopted the International Civil Aviation Organisation (ICAO)methodology of using a code system, known as the Aerodrome Reference Code,to specify the standards for individual aerodrome facilities that are suitable foruse by aeroplanes that have been grouped in a range of performances andsizes. The code is composed of two elements. Element 1 is a number related tothe aeroplane reference field length, and element 2 is a letter related to theaeroplane wingspan and outer main gear wheel span. A particular specificationis related to the more appropriate of the two elements of the code or to anappropriate combination of the two code elements. The code letter or numberwithin an element selected for design purposes is related to the critical aeroplane

characteristics for which the facility is provided.

2.1.6.2 The code number for element 1 shall be determined from column 1 of the tablebelow. The code number corresponding to the highest value of the aeroplanereference field length for which the runway is intended is to be selected.

Note: The determination of the aeroplane reference field length is solely for theselection of a code number and must not be confused with operationalrunway length requirements as determined by aircraft operators, whichare influenced by other factors.

2.1.6.3 The code letter for element 2 shall be determined from column 3 of the table

below. The code letter is selected according to the greatest wingspan or thegreatest outer main gear wheel span, whichever gives the more demanding code


35/330


_________________________________________________________________________________________________Version 0.1 (2 - 4) May 2008

letter, of the aeroplane(s) using or intending to use the facility.

2.1.6.4 For certified aerodromes, information about the aerodrome reference code letterfor each runway and taxiway should be set out in the Aerodrome Manual.

2.1.6.5 Unless otherwise agreed by ATO, aerodrome operators must maintain theaerodrome facilities in accordance with the applicable standards set out in thisMOS in relation to the aerodrome reference code for the facilities.

2.1.8 Providing for future larger aeroplanes

2.1.8.1 Nothing in this MOS is intended to inhibit the planning or provision of aerodromefacilities for larger aeroplanes that may be accommodated by the aerodrome at alater date. However, where movement area facilities are built for future largeraeroplanes, the aerodrome operator must liaise with the ATO to determineinterim notification of Reference Code and maintenance arrangements.

2.1.8.2 For master planning of aerodromes the appropriate aeroplane and aeroplanecharacteristics are to be selected. This MOS has included ICAO Code Fspecifications for aerodrome facilities intended for aeroplanes larger than B 747wide body aircraft.

Note: ICAO Circular 305 AN/177, Operation of New Larger Aeroplanes at

Existing Aerodromes issued June 2004 may provide useful informationwhen considering arrangements for safety matters associated with largeaeroplane ground operations.

2.1.9 Non-instrument and instrument runways

2.1.9.1 Runways are classified as non-instrument (also known as visual or circlingapproach) and instrument runways. Instrument runways are further categorizedas: non-precision, precision Category I, Category II, and Category IIIA, IIIB andIIIC.

2.1.9.2 Aerodrome operators must liaise with ATO before initiating any changes to therunway classification or instrument category as such a change will involvechanges to the standards of a number of otheraerodrome facilities.

2.1.9.3 This MOS contains specifications for precision approach runways category II andIII, for aerodrome facilities intended for aeroplanes with Reference Codenumbers 3 and 4 only. No specification is prescribed for code 1 or 2 precisionapproach runways, as it is unlikely that such facilities will be required.Aerodrome operators must liaise with ATO to ascertain mandatory requirementsif consideration is being given to installing ILS Category II or III facilities forReference Code 1 or 2 aeroplanes.

2.1.10 Non-precision approach runways

2.1.10.1 A non-precision approach runway is defined in Chapter 1. Non-precisionapproach procedures are designed by ATO and are published in the AIP.

2.1.10.2 Straight-in or runway aligned procedures are identified by the runway number inthe title of the approach chart (e.g. RWY 18 GPS or RWY 08 VOR/DME). Non-runway aligned approach procedures will not have the runway number in the title(e.g. GPS-S, GPS-N or NDB).

2.1.10.3 The results of accident enquiries have demonstrated that straight-in approaches

are much safer than circling approaches, especially at night. With the advent ofGPS, non-precision approach (NPA) runways can be provided without any

ground based navigation aid. Aerodrome operators of non-instrument runwaysmay upgrade their runways to NPA runways wherever it is practicable to do so.However, the benefit of having an NPA runway can only be realised if the runwaymeets the applicable NPA runway standards. These may include:

(a) increased runway strip width;(b) increased inner horizontal, conical and approach obstacle imitation

surfaces to be surveyed for obstacles;(c) spacing of runway edge lights; and(d) the availability of the wind direction indicator, near the threshold, if possible,
