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;
"aircraft" means any machine that can derive support in the atmosphere from the reactions of the air other than the reactions of the air against the earth's surface;
"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;
"EPNdB" means a unit for expressing effective perceived noise level determined in accordance with the method described in Appendix 1 of Annex 16 to the Chicago Convention;
"maximum total weight authorised" means the maximum total weight of the aircraft and its contents at which the aircraft 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 aircraft;
"the Minister" means the Minister for Transport and Power;
"prescribed" means prescribed by the Minister;
"subsonic aeroplane" means an aeroplane incapable of sustaining level flight at speeds exceeding the speed of 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 of 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 aircraft in certain locations and in certain circumstances.
5 Application of Order.
num: 5
paragraphs: This Order applies to—
(1) every subsonic aeroplane having turbine jet or turbine fan engines which—
( a ) requires for take-off a runway length in excess of 450 metres, and is powered
(i) by engines having a by-pass ratio of two or more and for which a certificate of airworthiness was first issued on or after the first day of March 1972,
or
(ii) by other classes of engines, unless it is an aeroplane in respect of which the application for a certificate of airworthiness for the prototype of the aeroplane was accepted before the 1st day of January 1969 or other equivalent procedure was effected by the certificating authorities of the state in which the aeroplane was manufactured before that date;
or
( b ) is powered by engines having a bypass ratio of less than 2 for which the application for a certificate of airworthiness for the prototype of the aeroplane was accepted, or another equivalent procedure was effected by the certificating authorities of the state in which the aeroplane was manufactured, before the 1st day of January 1969, and for which a certificate of airworthiness for the individual aeroplane is first issued on or after the 1st day of January, 1976.
(2) every propeller-driven aeroplane, except aeroplanes designed specifically for agricultural uses or fire-fighting, of maximum total weight authorised not exceeding 5700 kilograms for which—
( a ) application for the certificate of airworthiness for the prototype was accepted or an equivalent procedure was effected by the certificating authorities of the state in which the aeroplane was manufactured on or after the 1st day of January, 1975;
or
( b ) application for the certificate of airworthiness for the prototype was accepted or another equivalent procedure was effected by the certificating authorities of the state in which the aeroplane was manufactured before the 1st day of January, 1975, and for which a certificate of airworthiness for the individual aeroplane is first issued on or after the 1st day of January, 1980;
or
( c ) application for a change of type design which has a significant effect on the noise characteristics of the aeroplane was accepted or another equivalent prescribed procedure was carried out by the certificating authorities of the state in which the aeroplane was manufactured on or after the 27th day of February, 1975.
