(a) Each certificate holder shall
maintain sufficient qualified personnel to comply with the requirements of its
aerodrome certification manual and the applicable provisions of this Part.
(b) Each aerodrome operator shall
implement a programe to upgrade the competency of the personnel.
(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
