(2) Notwithstanding the revocation of the Air Navigation (Noise Certification and Limitation) Order, 1976, any noise certificate issued or validated under that Order and in force at the commencement of this Order shall remain in force and shall be deemed for all purposes as if it were a noise certificate issued under this Order.
3 Definitions.
num: 3
paragraphs: In this Order—
"aeroplane" means a power-driven heavier-than-air aircraft deriving its lift in flight chiefly from aerodynamic reactions on surfaces which remain fixed under given conditions of flight;
"authorised person" means a person authorised under section 64 of the Air Navigation and Transport Act, 1936 , (No. 40 of 1936);
"by-pass ratio" means the ratio of the air mass flow passing through the by-pass ducts of a gas turbine engine to the air mass flow passing through the combustion chambers of that engine, calculated at maximum thrust when the engine is stationary in the Standard Atmosphere at sea level as defined in Annex 8 to the Chicago Convention;
"Chicago Convention" has the meaning assigned to it by section 2 of the Air Navigation and Transport Act, 1946 , (No. 23 of 1946), and includes any annex to the Chicago Convention relating to international standards and recommended practices and adopted in accordance with the Chicago Convention, and any amendment of any such annex made in accordance with the Chicago Convention;
"derived version of an aeroplane" means an aeroplane which from the point of view of airworthiness is similar to the noise certificated original version but incorporates changes in type design which may affect its noise characteristics;
"maximum certificated take-off mass" means the maximum total mass of the aeroplane and its contents at which the aeroplane may take off anywhere in the world in the most favourable circumstances in accordance with the certificate of airworthiness in force in respect of the aeroplane;
"the Minister" means the Minister for Communications;
"subsonic jet aeroplane" means an aeroplane incapable of sustaining level flight at speeds exceeding the speed propagation of sound pressure waves in the air.
4 Purpose of Order.
num: 4
paragraphs: This Order is for the purposes of:—
(i) giving effect to Annex 16 — first edition, 1981 to the Chicago Convention in respect of noise certification of aeroplanes, and
(ii) making such directions as may be necessary from time to time in respect of procedures for the limitation of noise made by aeroplanes in certain locations and in certain circumstances.
5 Application of Order.
num: 5
paragraphs: This Order applies to:—
(1) Every subsonic jet aeroplane for which either the application for a certificate of airworthiness for the prototype was accepted or another equivalent procedure was effected by the certification authorities before the 6th day of October, 1977, except those aeroplanes:
( a ) requiring a runway length of 610 metres or less at maximum certificated mass for airworthiness; or
( b ) powered by engines with a by-pass ratio of 2 or more and for which a certificate of airworthiness for the individual aeroplane was first issued before the 1st day of March 1972; or
( c ) powered by engines with a by-pass ratio of less than 2, and for which either the application for certificate of airworthiness for the prototype was accepted or another equivalent procedure was carried out by the certificating authorities, before the 1st day of January, 1969, and for which a certificate of airworthiness for the individual aeroplane was first issued before the 1st day of January, 1976.
(2) Derived versions of any aeroplane specified in paragraph (1) of this Article for which the application for certification of a change in type design was accepted or another equivalent procedure was effected by the certificating authorities on or after the 26th day of November, 1981.
(3) Every subsonic jet aeroplane including any derived version, other than an aeroplane which requires a runway length of 610 metres or less at maximum certificated take-off mass for airworthiness in respect of which either the application for certificate of airworthiness for the prototype was accepted or another equivalent procedure was effected by the certificating authorities on or after the 6th day of October, 1977.
(4) Every propeller-driven aeroplane, including any derived version, except an aeroplane specifically designed for fire-fighting and agricultural purposes, of maximum certificated take-off mass exceeding 5,700 kilograms, other than an aeroplane which requires a runway length of 610 metres or less at maximum certificated mass for airworthiness—
( a ) for which the application for a certificate of airworthiness for the prototype was accepted or another equivalent procedure was effected by the certificating authorities on or after the 6th day of October, 1977; or
( b ) derived versions and individual aeroplanes of the types for which the application for the prototype was accepted or another equivalent procedure was effected by the certificating authorities before 6th October, 1977, and for which a certificate of airworthiness for the individual aeroplane was first issued on or after the 26th day of November, 1981.
(5) Every propeller-driven aeroplane, except those aeroplanes specifically designed for aerobatic purposes or agricultural or fire-fighting uses, of a maximum certificated take-off mass not exceeding 5,700 kilograms (but in the case of an application for a change in type design, the maximum certificated take-off mass may not exceed 6,500 kilograms, provided that the prototype has been certificated at a maximum certificated take-off mass not exceeding 5,700 kilograms) for which—
( a ) application for the certificate of airworthiness for the prototype was accepted, or another equivalent procedure was effected by the certificating authorities on or after the 1st day of January, 1975; or
( b ) a certificate of airworthiness for the individual aeroplane was first issued on or after the 1st day of January, 1980.
