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); and
(h) a heading indicator (directional gyroscope); and
(i) a turn and slip indicator except that only a slip indicator is required when a second attitude indicator usable through flight attitudes of 360 degrees of pitch and roll is installed; and
(j) means of indicating whether the power supply to the gyroscopic instruments is working satisfactorily; and
(k) except for aeroplanes engaged in night V.M.C. flights, means of preventing malfunctioning due to either condensation or icing of at least 1 airspeed indicating system.
      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 an alternate static source but not both sources simultaneously. Alternatively, they may be connected to a balanced pair of flush static ports.
      3 Except for aeroplanes engaged in night V.M.C. private and aerial work operations the instruments specified in paragraphs 1 (g), (h) and (i) of this Appendix must have duplicated sources of power supply unless the turn and slip indicator or the second attitude indicator specified in paragraph 1 (i) has a source of power independent of the power operating other gyroscopic instruments.
      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 paragraph 1 (h) of this Appendix, provided that such installation complies with the power supply requirements of clause 3 of this Appendix.
Appendix V

Electric lighting equipment flight under the I.F.R. at night (including night V.M.C.)

     The electric lighting equipment is:

      1 Instrument illumination
       Illumination for all instruments and equipment, used by the flight crew, that are essential for the safe operation of the aircraft. The illumination must be such that:
(a) all illuminated items are easily readable or discernible, as applicable; and
(b) its direct or reflected rays are shielded from the pilot's eyes; and
(c) its power supply is so arranged that in the event of the failure of the normal source of power, an alternative source is immediately available; and
(d) it emanates from fixed installations.

      2 Intensity control
       Means of controlling the intensity of the illumination of instrument lights, unless it can be demonstrated that non-dimmed instrument lights are satisfactory under all conditions of flight likely to be encountered.

      3 Landing lights
       2 landing lights except that, in accordance with the provisions of regulation 308 of CAR 1988,
