(b) Each aerodrome operator shall implement a programe to upgrade the competency of the personnel.

 

139.305 Operations

(a)  Reserved.

(b) Reserved.

(c)  Common reference systems:

(1)   Horizontal reference system: World Geodetic System-1984 (WGS-84) shall be used by aerodrome operator as the horizontal (geodetic) reference system. Reported aeronautical geographical coordinates (indicating latitude and longitude) shall be expressed in terms of the WGS-84 geodetic reference datum.

Note: Comprehensive guidance material concerning WGS-84 is contained in   ECAR Part 173.

(2)   Vertical reference system: Mean sea level (MSL) datum, which gives the relationship of gravity-related height (elevation) to a surface known as the geoid, shall be used by aerodrome operator as the vertical reference system.

Note 1: The geoid globally most closely approximates MSL. It is defined as the equipotential surface in the gravity field of the Earth which coincides with the undisturbed MSL extended continuously through the continents.

Note 2: Gravity-related heights (elevations) are also referred to as orthometric heights while distances of points above the ellipsoid are referred to as ellipsoidal heights.

(3)   Temporal reference system:

(i)    The Gregorian calendar and Coordinated Universal Time (UTC) shall be used by aerodrome operator as the temporal reference system.

(ii)   When a different temporal reference system is used, this shall be reported by aerodrome operatot to the ECAA to be indicated in GEN 2.1.2 of the Aeronautical Information Publication (AIP).

(d)   Safety management system:

(1)   As part of the certification  process, aerodromes’ administrator shall prepare an aerodrome manual which will include all pertinent information on the aerodrome site, facilities, services, equipment, operating procedures, organization and management including a safety management system, and submit it to the ECAA for acceptance prior to granting the aerodrome certificate.

Note: -The intent of a safety mangement system is to have in place an organized and orderly approach in the management of aerodrome safety by the aerodrome operator. Guidance on an aerodrome safety management system is given in the EAC 139 -5 and in the EAC 139-6 ( under preparation )

          - Also refer to EAC 00_11

(2)  The acceptable level of safety to be achieved shall be established by theECAA.

Note.— Guidance on defining acceptable level of safety is contained in the EAC 139 -6 ( under preparation )         

(3)  The certified aerodromes shall implement a safety management system at the aerodrome acceptable to the ECAA that, as a minimum;

(i)    Identifies safety hazards,

(ii)   Ensures the implementation of remedial action necessary to maintain agreed safety performance .

(iii)               Provides for continuous monitoring and regular assessment of the safety performance, and

(iv)    Aims  at a continuous improvement of the overall performance of the safety management system.

Note.- Guidance on defining safety performance is contained in the (EAC 139-6 under preparation )            

 (4)   A safety management system shall clearly define lines of safety accountability throughout an aerodrome, including a ditect accountability for safety on the part of senior management.

Note: A framework for the implementation and maintenance of asafety management system is contained in Appendix 7 .Guidance on safety management system is contained the EAC 139-5, and EAC 139-6(under preparation) .

 (e)  Airport design:

(1)   Architectural and infrastructure-related requirements for the optimum implementation of international civil aviation security measures shall be integrated into the design and construction of new facilities and alterations to existing facilities at an aerodrome.

Note: Guidance on all aspects of the planning of aerodromes including security considerations is contained in EAC 139-15.

(2) The design of aerodromes should take into account, where appropriate, land-use and environmental control measures.

Note: Guidance on land-use planning and environmental control measures are described in the EAC139-16.

 (f)   Reference code:

      Introductory Note: The intent of the reference code is to provide a simple method for interrelating the numerous specifications concerning the characteristics of aerodromes so as to provide a series of aerodrome facilities that are suitable for the aeroplanes that are intended to operate at the aerodrome. The code is not intended to be used for determining runway length or pavement strength requirements. The code is composed of two elements which are related to the aeroplane performance characteristics and dimensions. Element 1 is a number based on the aeroplane reference field length and element 2 is a letter based on the aeroplane wing span 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 critical aeroplane characteristics for which the facility is provided. When applying this Part, the aeroplanes which the aerodrome is intended to serve are first identified and then the two elements of the code

(1)  An aerodrome reference code, code number and letter, which is selected for aerodrome planning purposes shall be determined in accordance with the characteristics of the aircraft for which an aerodrome facility is intended.

(2)  The aerodrome reference code numbers and letters shall have the meanings assigned to them in, Table 1-1.

(3)  The code number for element 1 shall be determined from Table 1-1, column 1, by selecting the code number corresponding to the highest value of the aircraft reference field lengths of the aircraft for which the runway is intended.

(4)  The code letter for element 2 shall be determined from Table 1-1, column 3, by selecting the code letter which corresponds to the greatest wing span, or the greatest outer main gear wheel span, whichever gives the more demanding code letter for the aircraft for which the facility is intended.

(5)   Guidance to assist the aerodrome in determining the aerodrome reference code is given in EAC 139-9 and EAC 139-10
