its lighting will continue to operate for 30 minutes following the failure of the electrical power generating system without any action by the flight crew; and
(c) the position size and lighting of the instrument display allows its use from the pilot in command's operating station by day and by night; and
(d) the operation is independent of other attitude indicator installations.
      7 CASA may, having regard to the type of helicopter, 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.
      8 A gyro-magnetic type of remote indicating compass installed to meet the requirements of subparagraph 1 (c) (ii) and 2 (c) (ii) of this Appendix may be considered also to meet the requirement for a heading indicator specified in paragraph 1 (h) or 2 (h) of this Appendix, provided that such installation complies with the power supply requirements of clause 4 of this Appendix.
      9 CASA may, having regard to the type of helicopter, and the flight presentation, response and acuity standard of the instrument concerned, approve the use of attitude indicators which have a dial presentation of less than 5 inches, in lieu of the indicators specified at paragraphs 1 (g), 2 (g) and 5 of this Appendix.
Appendix VIII

Instruments required for night V.M.C. flight in helicopters except while engaged in agricultural operations

      1 The flight and navigational instruments required are:
(a) an airspeed indicating system; and
(b) a sensitive pressure altimeter; 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. This may be carried on the person of the pilot or navigator; and
(e) an outside air temperature indicator; and
(f) an attitude indicator (artificial horizon); and
 (i) standby attitude indicator; or
 (ii) turn indicator; and
(g) a heading indicator (directional gyroscope); and
(h) a slip indicator; and
(i) a vertical speed indicator; and
(j) means of indicating whether the power supply to the gyroscopic instruments is working satisfactorily.
      2 For operations onto vessels or platforms at sea by night an instantaneous vertical speed indicator is required in place of the vertical speed indicator specified at paragraph 1 (i) of this Appendix.
      3 The attitude indicator and standby attitude indicator or turn indicator as specified in paragraph 1 (f) of this Appendix, must have separate and independent power sources.
      4 A gyro-magnetic type of remote indicating compass installed to meet the requirements of subparagraph 1 (c) (ii) of this Appendix may be considered also to meet the requirement for a heading indicator specified in
