       (8)Air data computers test
(a) The tests set out in subclauses (1) to (7) do not apply for air data computers or for systems similar to air data computers (a similar type).
(b) Paragraph (c) sets out the tests for the following altimeters:
           (i) an altimeter that is an air data computer or similar type with associated computing systems;
 (ii) an altimeter that incorporates air data correction internally.
(c) An altimeter mentioned in paragraph (b), must be tested as follows:
           (i) in the manner, and to the specifications, provided by the manufacturer of the equipment or aircraft in which the altimeter is installed;
           (ii) in accordance with the instructions for continuing airworthiness incorporated in a modification approval for the equipment or aircraft in which the altimeter is installed.

         Clause 3 Automatic pressure altitude encoders and ATC transponder system integration test
       Automatic pressure altitude encoder test and other transponder devices
       Measure the automatic pressure altitude value at the output of the installed ATC transponder when interrogated on Mode C at a sufficient number of test points to ensure that the altitude reporting equipment, altimeters, and ATC transponders perform their intended functions as installed in the aircraft. The difference between the automatic reporting output and the altitude displayed at each altimeter must not exceed 125 feet.

Appendix 2

Prescribed single-engine aeroplanes (PSEA)
Note   Paragraph 10.1 of this CAO requires an aeroplane operated as a PSEA to comply with each of the following requirements. Aircraft systems and equipment mentioned within these requirements must be approved under regulation 21.305 of CASR.

Part 1 Compliance requirements
Note 1   See paragraph 10.1 of this CAO.
Note 2   The aeroplane must comply with each of the following requirements and be approved by CASA. (See subsection 10 above.) Aircraft systems and equipment mentioned within these requirements must be approved under regulation 21.305 of CASR.

1 Aeroplane
       The aeroplane type must have been originally certificated as a turbine-powered aeroplane under the certification requirements set under Part 23 of CASR that are equivalent to FAR 23 amendment 28 or a subsequent amendment.
Note   Thus, a turbine conversion of an originally certificated piston-powered aeroplane cannot comply.

2 Engine
       2.1The aeroplane engine type (the engine type) must have documented evidence of an acceptable world fleet reliability rate (WFRR) in accordance with this clause.
       2.2The WFRR must be calculated as a 6 month rolling average, and consist of:
(a) an in-flight shutdown (IFSD) rate of not more than 0.01 per 1 000 hours based on a minimum experience history of 100 000 hours' time-in-service; or
(b) an IFSD rate for individual engine components gained in the same engine types, or in equivalent engine types as determined by CASA, that collectively meet
