2 DEFINITIONS
Unless a contrary intention is apparent, terms used in this section shall have the same meanings as defined in the airworthiness requirements of the country in which the aeroplane was originally certificated.
3 DESIGN STANDARDS
GENERAL
3.1 CASA may modify the design standards to be met if it considers that the standards specified in this subsection do not adequately relate to particular features or characteristics of an aeroplane type.
3.2 Non-compliance with a design standard may be accepted if it can be shown to CASA's satisfaction that such non-compliance is compensated for by factors that provide an equivalent level of safety.
3.3  Subject to paragraphs 3.4.2 and 3.4.3, an aeroplane of Australian design must comply with the design standards specified in paragraph 3.5 and subsequent of this subsection and with the design standards specified in Federal Aviation Regulation Part 23 of the United States of America or British Civil Airworthiness Requirements Section K, modified to the extent CASA considers acceptable with regard to their application to the particular design.
3.4 Subject to paragraphs 3.4.2 and 3.4.3, an aeroplane of overseas design must comply with the design standards specified in paragraphs 3.5 and subsequent of this subsection.
3.4.1 Flight Handling Qualities
An aeroplane to which this section applies must comply with the requirements of 1 of the following design standards in relation to flight handling qualities:
 (a) British Civil Airworthiness Requirements Section S;
 (b) Federal Aviation Regulations Part 23;
 (c) Joint Aviation Requirements JAR-VLA (Very Light Aeroplanes).
Note: The Civil Aviation Safety Authority publication "Flight Test Guide for Certification of CAO 101.28 Category Aeroplanes" contains information on compliance with the requirements of the standards referred to in paragraph 3.4.1.
3.4.2 In spite of paragraphs 3.3 and 3.4, CASA may, in writing, exempt a particular aeroplane, or a class of aeroplanes, to which this section applies from compliance with specified provisions of this section.
3.4.3 An exemption under paragraph 3.4.2 is subject to the aeroplane exempted complying with such requirements (if any) as CASA specifies in the exemption as being necessary in the interests of safety and having regard to the purposes for which the aeroplane is to be used.
FLIGHT
3.5 Stalling speeds

 (1) The stalling speed VSO or minimum steady flight speed, in knots CAS, shall be determined with:
 (a) engine(s) idling with throttle(s) closed; and
 (b) propeller(s) in the take-off position; and
 (c) landing gear extended; and
 (d) wing flaps in the landing position; and
 (e) centre of gravity in the most unfavourable position within the allowable range; and
 (f) weight used when VSO is being used as a factor to determine compliance with a particular
