Specification. Cabin air conditioning management during performance demonstration as described in Subparagraph 6.3 below may be such as to
optimise the A330-200 Aircraft performance while meeting the minimum air conditioning requirements defined above. Unless otherwise stated no air
will be bled from the engines for anti-icing.
Cruise performance at ** and above is based on a centre of gravity position of **.
5.4 The engines will be operated using not more than the engine manufacturer's maximum recommended outputs for take-off, maximum go-round,
maximum continuous, maximum climb and cruise for normal operation unless otherwise stated.
5.5 Where applicable the Guarantees assume the use of an approved fuel having a density of ** per US gallon and a lower heating value of **.
5.6 Speech Interference Level (SIL) is defined as the arithmetic average of the sound pressure levels in the **. A-Weighted sound pressure level (dB(A)) is
as defined in the American National Standard Specification ANSI.4-1971.
5.7 All guaranteed interior noise levels refer to an aircraft with standard acoustic insulation, an interior completely furnished and equipped with standard
cloth seats. The effect of Buyer furnished equipment other than standard passenger cloth seats (standard seats or acoustically equivalent) shall be the
responsibility of the Buyer. (Remark: Leather seats tend to increase interior noise levels by 1-2 dB)
Effects on noise of Buyer furnished equipment and installations by or on behalf of the Buyer are not covered by this guarantee.
6 GUARANTEE COMPLIANCE
6.1 Compliance with the Guarantees shall be demonstrated using operating procedures and limitations in accordance with those defined by the certifying
Airworthiness Authority and by the Seller unless otherwise stated.
6.2 Compliance with the take-off, second segment, en-route one engine inoperative, approach climb and landing elements of the Guarantees will be
demonstrated with reference to the approved Flight Manual.
6.3 Compliance with those parts of the Guarantees defined in paragraph 2 above not covered by the requirements of the certifying Airworthiness Authority
shall be demonstrated by calculation based on data obtained during flight tests conducted on one (or more, at the Seller's discretion) aircraft of the same
aerodynamic configuration as the A330-200 Aircraft and incorporated in the In-Flight Performance Program and data bases ("the IFP") appropriate to
the A330-200 Aircraft.
6.4 Compliance with the Manufacturer's Weight Empty guarantee defined in Paragraph 3 shall be demonstrated with reference to a weight compliance
report.
6.5 The approved A330-200 Aircraft flight manual shall be used to demonstrate compliance with the guarantees of certification noise levels.
