either condensation or icing; and
(b) 2 sensitive pressure altimeters; and
(c)  (i) a direct reading magnetic compass; or
 (ii) a remote indicating compass and a standby direct reading magnetic compass; and
(d) an accurate timepiece indicating the time in hours, minutes and seconds; and
(e) a rate of climb and descent indicator (vertical speed indicator); and
(f) an outside air temperature indicator; and
(g) 2 attitude indicators (artificial horizons); and
(h) a heading indicator (directional gyroscope or equivalent approved by CASA); and
(i) a turn and slip indicator except that only a slip indicator is required when a third attitude indicator usable through flight attitude of 360 degrees pitch and roll is installed; and
(j) a means of indicating whether the power supply to the gyroscopic instruments is working satisfactorily; and
(k) in turbo-jet aeroplanes with operating limitations expressed in terms of Mach number, a Mach number indicator (Machmeter).
      2 The instruments specified in paragraphs 1 (a), (b), (e) and (k) of this Appendix must be capable of being connected to either a normal or alternate static source but not both sources simultaneously. Alternatively, they may be connected to a balanced pair of flush static ports.
      3 The instruments specified in paragraphs 1 (g), (h) and (i) of this Appendix must have duplicated sources of power supply.
      4 CASA may, having regard to the type of aeroplane, approve an attitude indicator incorporated in an automatic pilot system as being 1 of the 2 attitude indicators required by paragraph 1 (g) of this Appendix.
      5 A gyro-magnetic type of remote indicating compass installed to meet the requirements of subparagraph 1 (c) (ii) of this Appendix may also be considered to meet the requirement for a heading indicator specified in paragraph 1 (h) of this Appendix, provided it has a duplicated power supply.
Appendix IV

Instruments required for aeroplanes engaged in:
        (i) aerial work and private operations under the I.F.R. (including night V.M.C.); and
        (ii) charter operations under night V.M.C; and
        (iii) I.F.R. freight only charter operations in aeroplanes with maximum take‑off weight not greater than 5 700 kg.

      1 The flight and navigational instruments required are:
(a) an airspeed indicating system; and
(b) a sensitive pressure altimeter; and
(c)  (i) direct reading magnetic compass; or
 (ii) a remote indicating compass and a standby direct reading magnetic compass; and
(d) an accurate timepiece indicating the time in hours, minutes and seconds, except that this may be omitted if it is carried on the person of the pilot or navigator; and
(e) a rate of climb and descent indicator (vertical speed indicator) for other than night V.M.C. flights; and
(f) an outside air temperature indicator; and
(g) an attitude indicator (artificial horizon);
