b) ambient air temperature of 25°C, i.e. ISA + 10°C. 6.5 Test procedures 6.5.1 Either the test procedures described in 6.5.2 and 6.5.3 or equivalent test procedures approved by the certificating authority shall be used. 6.5.2 Tests to demonstrate compliance with the maximum noise levels of 6.3 shall consist of a series of level flights overhead the measuring station at a height of The aeroplane shall pass over the measuring point within ±10° from the vertical. 6.5.3 Overflight shall be performed at the highest power in the normal operating range,2 stabilized airspeed and with the aeroplane in the cruise configuration. Note.— Guidance material on the use of equivalent procedures is provided in the Environmental Technical Manual on the Use of Procedures in the Noise Certification of Aircraft (Doc 9501). 2. This is normally indicated in the aeroplane flight manual and on the flight instruments. . +10 m (985 +30 ft) –30 –100 2007/70/II. szám ANNEX 16 — VOLUME I II-7-1 24/11/05 CHAPTER 7. PROPELLER-DRIVEN STOL AEROPLANES Note.— Standards and Recommended Practices for this chapter are not yet developed. In the meantime, guidelines provided in Attachment B may be used for noise certification of propeller-driven STOL aeroplanes for which a certificate of airworthiness for the individual aeroplane was first issued on or after 1 January 1976. 2007/70/II. szám ANNEX 16 — VOLUME I II-8-1 24/11/05 CHAPTER 8. HELICOPTERS 8.1 Applicability Note.— See also Chapter 1, 1.9. 8.1.1 The Standards of this chapter shall be applicable to all helicopters for which 8.1.2, 8.1.3, and 8.1.4 apply, except those designed exclusively for agricultural, fire fighting or external load carrying purposes. 8.1.2 For a helicopter for which the application for the certificate of airworthiness for the prototype was accepted, or another equivalent prescribed procedure was carried out by the certificating authority, on or after 1 January 1985, except for those helicopters specified in 8.1.4, the noise levels of 8.4.1 shall apply. 8.1.3 For a derived version of a helicopter for which the application for a change of type design was accepted, or another equivalent prescribed procedure was carried out by the certificating authority, on or after 17 November 1988, except for those helicopters specified in 8.1.4, the noise levels of 8.4.1 shall apply. 8.1.4 For all helicopters, including their derived versions, for which the application for the certificate of airworthiness for the prototype was accepted, or another equivalent prescribed procedure was carried out by the certificating authority, on or after 21 March 2002, the noise levels of 8.4.2 shall apply. 8.1.5 Certification of helicopters which are capable of carrying external loads or external equipment shall be made without such loads or equipment fitted. Note.— Helicopters which comply with the Standards with internal loads may be excepted when carrying external loads or external equipment, if such operations are conducted at a gross mass or with other operating parameters which are in excess of those certificated for airworthiness with internal loads. 8.1.6 An applicant under 8.1.1 may alternatively elect to show compliance with Chapter 11 instead of Chapter 8 if the helicopter has a maximum certificated take-off mass of 3 175 kg or less. 8.2 Noise evaluation measure The noise evaluation measure shall be the effective perceived noise level in EPNdB as described in Appendix 2. 8.3 Reference noise measurement points A helicopter, when tested in accordance with these Standards, shall not exceed the noise levels specified in 8.4 at the following points:
