| (1) | The operator shall not operate a helicopter in accordance with IFR, unless such helicopter is equipped with— |
| (b) | an accurate time-piece on board indicating the time in hours, minutes and seconds; |
| (c) | two sensitive pressure altimeters with subscale settings, calibrated in hectopascals, adjustable for any barometric pressure setting likely to be encountered during flight; |
| (d) | in the case of a helicopter having a maximum certificated mass exceeding 3 180 kilograms, a radio altimeter with an audio warning operating below a pre-set height and a visual warning capable of operating at a height selectable by the pilot; |
| (e) | an airspeed indicator system with heated pitot tube or equivalent means for preventing malfunctioning due to either condensation or icing, including a warning indicator of pitot heater failure; |
| (f) | a vertical-speed indicator; |
| (g) | a turn-and-slip indicator or in lieu thereof, an additional attitude indicator powered by a power source separate from that of the main attitude indicator; |
| (h) | an attitude indicator; |
| (i) | a single standby attitude indicator, capable of being used from either pilot's station, which— |
| (i) | is powered continuously during normal operation and, after a total failure of the normal electrical generating system, is powered from a source independent of the normal electrical generating system; |
| (ii) | provides reliable operation for a minimum of 30 minutes after total failure of the normal electrical generating system, taking into account other loads on the emergency power supply and operational procedures; |
| (iii) | operates independently of any other attitude indicating system; |
| (iv) | is operative automatically after total failure of the normal electrical generating system; and |
| (v) | is appropriately illuminated during all phases of operation: |
Provided that if the standby attitude instrument system is capable of being used through flight attitudes of 360° of pitch and roll, the turn-and-slip indicators may be replaced by slip indicators;
| (j) | a stabilised direction indicator; |
| (k) | a means of indicating on the flight deck the outside air temperature in degrees Celsius; |
| (I) | an alternate source of static pressure for the altimeter and the airspeed and vertical speed indicators; and |
| (m) | a chart holder in an easily readable position which can be illuminated, if to be operated by night. |
| (n) | communication, navigation and surveillance equipment as prescribed in regulations 91.05.1 and 91.05.2. |
[Regulation 128.05.3(1)(n) inserted by regulation 15(a) of Notice No. R. 432, GG 40846, dated 19 May 2017 (Sixteenth Amendment of the Civil Aviation Regulations, 2017)]
| (2) | If two pilots are required to operate the helicopter, other than in training or testing, the second pilot's station shall be equipped with— |
| (a) | a sensitive pressure altimeter with a subscale setting, calibrated in hectopascals, adjustable for any barometric pressure setting likely to be encountered during flight, which may be one of the two altimeters required under subregulation (1)(c); |
| (b) | an airspeed indicator system with heated pitot tube or equivalent means for preventing malfunction due to either condensation or icing, including a warning indicator of pitot heater failure; |
| (c) | a vertical-speed indicator; |
| (d) | a turn-and-slip indicator, or in lieu thereof, an additional attitude indicator powered by a power source separate from that of the main attitude indicator; |
| (e) | an altitude indicator; and |
| (f) | a stabilised direction indicator. |
| (3) | In complying with the provisions of paragraph (1)(i) it shall be clearly evident to the flight crew members when such standby altitude indicator is being operated by emergency power. |
| (4) | Where the standby altitude indicator referred to in paragraph (1)(i) has its own dedicated power supply, there shall be an associated indicator, either on the instrument or the instrument panel, when such power supply is in use. |
