APPENDIX 3. NOISE EVALUATION METHOD FOR NOISE CERTIFICATION OF PROPELLER-DRIVEN AEROPLANES NOT EXCEEDING 8 618 kg - APPLICATION FOR CERTIFICATE OF AIRWORTHINESS FOR THE PROTOTYPE ACCEPTED BEFORE 17 NOVEMBER 1988 Note.- See Part II, Chapter 6. 1. INTRODUCTION a no precipitation Note 1.- This noise evaluation method includes b relative humidity not higher than 95 per cent and not lower than 20 per cent and ambient temverature not a noise cettijication test and measurement conditions above 35C and not below 2C at 1.2 rn i4 ft above b measurement of aeroplane noise received on the ground and ground except that on a diagram of temperature plotted against relative humidity combinations of temuerature and relative humidity which fall below a c reporting of ahta to the certificating authori and stright line between 2C and 60 per cent and 35C correction of measured data. and 20 per cent shall be avoided Note 2.- The instructions and procedures given in the c reported wind not above 19 kmlh 10 kt at 1.2 m 4 ft above ground and cross-wind component not method are clearly delineated to ensure nnlfomity during compliance tests, and to permit comparison between tests of above 9 km/h 5 kt at 1.2 m 4 ft above ground. Flights shall be made in equal numbers with tail and various types of aeroplanes, conducted in various geogra- head wind components and phical locations. The method applies only to aeroplanes within the applicability clauses of Part II, Chapter 6. 2. NOISE CERTIFICATION TEST AND MEASUREMENT CONDITIONS d no temperature inversions or anomalous wind condi- fions that wou\d significdly affec-t the noise level of the aeroplane when the noise is recorded at the measuring points specified by the certificating authority. 2.1 General 2.3 Aeroplane testing procedures This section prescribes the conditions under which noise certification tests shall be conducted and the measurement procedures that shall be used to measure the noise made by the aeroplane for which the test is conducted. 2.2 General test conditions 2.2.1 Locations for measuring noise from an aeroplane in flight shall be surrounded by relatively flat terrain having no excessive sound absorption characteristics such as might be caused by thick, matted, or tall grass, shrubs, or wooded areas. No obstructions which significantly influence the sound field from the aeroplane shall exist within a conical space above the measurement position, the cone being defined by an axis normal to the ground and by a half-angle 75" from this axis. 2.3.1 The test procedures and noise measurement proce- dure shall be acceptable to the airworthiness and noise certifi- cating authorities of the State issuing the certification. 2.3.2 The aeroplane height and lateral position relative to the microphone shall be determined by a method indepen- dent of normal flight instrumentation such as radar tracking, theodolite triangulation, photographic scaling techniques or other methods to be approved by the certificating authority. 3. MEASUREMENT OF AEROPLANE NOISE RECEIVED ON THE GROUND 3.1 General 2.2.2 The tests shall be carried out under the following 3.1.1 ' All measuring equipment shall be approved by the atmospheric conditions certificating authority.
