Chapter 2: Application of Standards to Aerodromes Section 2. Operating procedures for certified and registered aerodromes differ and are set out in separate Chapters. However, until it is replaced or upgraded, details of the non-compliant facility must be recorded in the Aerodrome Manual, including: a identification of the facility; and b the date or period when the facility was first introduced or last upgraded as the case may be ; and c a description of, or documented evidence of, the standard with which the facility complies, including a supporting reference to the version and date of the MOS, RPA, AEI, APEI, API or other aerodrome facility standard embodying the standard with which the facility complies; and d details of the plans and timescale for replacing or upgrading the facility so that it complies with this MOS.

Note: As part of the audit of an aerodrome operator, CASA may require the operator to supply evidence showing past and current bona fide efforts to implement the plan and timescale 2.

However, until it is replaced or upgraded, details of the non-compliant facility must be recorded in accordance with paragraph F of CASR applied to the application; and b include a clear indication of whether, and when, full compliance with the MOS would occur. The Manual must contain details of the exemption, reason for the granting, any resultant limitations imposed, and similar relevant information. The Code is composed of two elements: element 1 is a number related to the aeroplane reference field length; and element 2 is a letter related to the aeroplane wingspan and outer main gear wheel span.

A particular specification is related to the more appropriate of the two elements of the Code or to an appropriate combination of the two Code elements.

The Code letter or number within an element selected for design purposes is related to the characteristics of the aeroplane types for which the facility is intended. The Code number corresponding to the highest value of the aeroplane reference field lengths for which the runway is intended is to be selected. Subject to paragraph 2. For certified aerodromes, information of the Aerodrome Reference Code letter for each runway and taxiway shall be set out in the Aerodrome Manual.

However, where movement area facilities are built for future larger aeroplanes, the aerodrome operator must liaise with the relevant CASA office to determine interim notification of Reference Code and maintenance arrangements.

Chapter 3: Applying for an Aerodrome Certificate Section 3. Operators of other aerodromes may also apply for an aerodrome certificate. It is the responsibility of the applicant to ensure that use of the site as an aerodrome is in compliance with other federal, state and local statutory requirements. The aerodrome certificate does not absolve the applicant from observing such requirements. The standards to meet the requirements are set out in various chapters in this Manual of Standards MOS.

However, it should be clearly understood that the CASA sample checking process does not absolve the applicant from the responsibility to provide accurate information. This may involve more time and resources and may result in restrictions being imposed on aircraft operations.

Chapter 4: Applying to Register an Aerodrome Section 4. A registered aerodrome will have aerodrome information published in ERSA, and changes to aerodrome information or conditions affecting aircraft operations can be notified through the NOTAM system. It is the responsibility of the applicant to ensure that use of the site as an aerodrome is in compliance with other federal, state and local authority requirements.

The aerodrome registration does not absolve the applicant from observing such requirements. The completed form, together with aerodrome information for publication in ERSA and confirmation from an approved person as prescribed in CASR Part , that the aerodrome meets applicable safety standards, shall be returned to the nearest CASA office. The inspection is normally only required if the information supplied is, in the opinion of the Aerodrome Inspector, inadequate or requires further clarification.

Note 1 Instrument approach procedures are classified as follows:. Note 2 When preparing or nominating their infrastructure to support the desired aircraft operation, the aerodrome operator determines the classification of instrument runway for which the runway is to be nominated provided that the relevant standards in this MOS are achieved. A certified designer under Part of CASR may then be tasked to design the optimal terminal instrument flight procedure to the capabilities of the instrument runway.

Note 3 Special Authorisation Category operations may only be utilised by aircraft operators who meet specific requirements for flight crew competency, aircraft capability and any conditions relevant to the terminal instrument flight procedure. Note 4 The visual aids provided need not necessarily be matched to the scale of the non-visual aids provided.

Note When making a selection, CASA recommends that an aerodrome operator should consider the aircraft types and operations to be accommodated because it is such considerations which dictate the appropriate design, and operating and reporting standards, for the facility.

Table 4. Code element 1. Note The minimum aeroplane reference field length determines the code number. However, provided it meets at least the minimum length required for a particular code number, the actual runway length does not otherwise dictate the code number selected by an operator.

The practical minimum length for the runway, and the nominated ARC, are each selected by the aerodrome operator. Note The choice of the greatest wingspan lies with the aerodrome operator. A failure to choose that which is the most demanding of applicable options may result in operational limitations for a particular aircraft type. Code element 2. Up to but not including 15 m.

The terms weight and mass used in this MOS have the same meaning. Note: See the definition of upgrade in subsection 1. The reconfiguring of an existing facility including, for example, an apron to cater for more or larger aircraft constitutes an upgrade. Note: As part of the audit of an aerodrome operator, CASA may require the operator to supply evidence showing past and current bona fide efforts to implement the plan and timescale. Note: The purpose of such qualifying phrases is to recognise that sometimes compliance with particular standards is not possible in some circumstances.

The purpose of paragraph 2. Note: The determination of the aeroplane reference field length is solely for the selection of a Code number and must not be confused with runway length requirements, which are influenced by other factors. Table 2. Aeroplane reference field length. Up to but not including 4. However, a failure to comply with subsection 2. Note: Aircraft operators will not be permitted to conduct SA Category I instrument approach operations unless aerodrome control is in operation.

Note: The runway may have electronic RVR equipment in the other zones of the runway. Absence of an approach lighting system or a shorter approach lighting system will result in higher RVR minima.

Volume 1. Manual of Standards Part —Aerodromes Version 1. Table of Contents Table of Contents.. Chapter 1: Introduction Section 1. Paragraph 92 1 b of the Civil Aviation Regulations has the effect of authorising a place for use as an aerodrome if it is certified or registered under Part of the Civil Aviation Safety Regulations CASR Together with Part of CASR , it sets out certain standards for certified aerodromes, registered aerodromes, and other aircraft landing areas where aircraft arrive, depart or move that are not certified or registered ALAs.

Aerodrome safety is a vital link in aviation safety and the applicable provisions of the MOS must be complied with to ensure aviation safety. D of CASR is that when an aircraft with a maximum passenger seating capacity of more than 9 but not more than 30 seats uses an ALA at least once a week for regular public transport operations, the operator of the ALA must conduct safety inspections, and have at least 1 reporting officer who: a is trained in accordance with the provisions of the MOS for reporting officers; and b monitors the serviceability of the ALA in accordance with the provisions of the MOS for such monitoring.

E of CASR is that all operators of certified and registered aerodromes must ensure the following: a that airspace monitoring around the aerodrome is in accordance with the MOS for such monitoring; b that obstacle limitation surfaces are established in accordance with the provisions of the MOS for obstacle limitation surfaces. Where this MOS incorporates by reference standards from other documents, the incorporated standards become part of this MOS.

A Note is not part of the standard. In those parts of the MOS where it is necessary to establish the context of standards to assist in their comprehension, the sense of parent regulations has been reiterated. ACs may explain certain regulatory requirements by providing interpretive and explanatory materials. It is expected that service providers will document internal actions in their own operational manuals, to put into effect those, or similarly adequate, practices.
