on, an aircraft although not required by this Chapter to be so fitted or carried, then:
(a) the equipment need not have been compliant with the requirements of, or approved under, Part 21 of CASR; and
(b) for a foreign-registered aircraft — the equipment need not have been approved by the NAA of the aircraft's State of registry; and
(c) no information provided by the equipment may be used by the flight crew to comply with any requirement of this Chapter in relation to equipment that is required to be fitted or carried for communications or navigation; and
(d) the equipment, whether functional or otherwise, must not at any time affect the safety of the operation or the airworthiness of the aircraft.

22.04 Visibility and accessibility of equipment
       (1) This section applies in relation to equipment that is required for the operation under a Part of the CASR or under this Chapter, to be fitted to, or carried on, an aircraft.
       (2) Equipment that is required for a pilot's manual or visual use in, or from, the cockpit must be visible to, and usable by, the pilot from the pilot's seat in the aircraft.
       (3) Emergency equipment that is required to be fitted to, or carried on, an aircraft for a flight must be easily accessible for immediate use in the event of an emergency.
       (4) Unless the contrary intention appears in a particular provision:
(a) a reference to a pilot seeing or viewing anything from a pilot's seat is taken to mean that the thing is seen or viewed from the pilot's normal sitting position in the seat; and
(b) any mention of feet (or ft) in the context of an altitude is taken to mean feet above mean sea level (AMSL), unless otherwise stated.

22.05 Serviceability of equipment
        Any equipment required by this MOS to be fitted to, or carried on, an aircraft for a flight must be operative unless:
(a) another provision of the civil aviation legislation provides otherwise; or
       Note 1   A minimum equipment list (a MEL), approved under regulation 91.935, can only permit equipment required to be fitted to, or carried on, an aircraft by this MOS, to be unserviceable within the limits of the requirements contained in this MOS. An example from the Part 91 MOS is that section 26.26 of that MOS contains an allowable time period of 72 hours related to flights with inoperative altitude alerting equipment. An MEL would not be approved if it contained a maximum time period for altitude alerting equipment to be inoperative that was greater than the time period specified by either a master minimum equipment list (MMEL) or the applicable civil aviation legislation.
