torch may be approved as meeting the requirement for a second light.
 (ii) 2 white lights operable by the pilot and trainable in azimuth and elevation without removing his/her hands from the flying controls; and
          Note   A single white light having 2 separately energized filaments may be approved as meeting this requirement provided that the selection of the alternative light can be accomplished by the pilot without removing his/her hands from the flying controls.
(c) with an approved inter-communication system which will permit continuous communication between the pilot(s) and aircrewman/winch operator.
       6.4When the flight attitude, height and position of the helicopter cannot be maintained by reference to external objects adequately illuminated by ground or celestial lighting, a helicopter shall not engage in winching operations over the surface of the sea or a body of water at night unless it is equipped:
(a) as specified in paragraph 4.2 and Appendix VII of section 20.18; and
(b) with the lights and inter-communication system specified in subparagraphs 6.3 (b) and (c).
Note   At all times when the helicopter is being operated below the minimum I.M.C. airspeed the equipment associated with the automatic pilot and/or automatic stabilisation system shall provide the pilot(s) with an easily interpreted and accurate display of the height of the helicopter above the surface of the sea or water, ground speed forwards, backwards, to the left and right and vertical speed in the correct sense.

7 Winching
       7.1In the case of charter operations involving the carriage of passengers for hire or reward to or from any place on land and all operations involving winching over offshore platforms or vessels, multi-engine helicopters capable of hovering out of ground effect with 1 engine inoperative during the actual winching operation shall be used.
       7.2In determining hover out of ground effect performance, up to 50% of the forecast wind, or 80% of the wind measured at the ship or site may be used. The maximum figure so derived for hover performance calculations shall not exceed 20 knots. If a valid forecast is not available and an accurate wind measurement cannot be obtained, the hover performance calculations shall be predicted on nil wind.
       7.3In actual rescue operations or in emergency situations e.g. insertion of fire‑fighters or emergency service personnel where there is a demonstrated urgent requirement for a winch-equipped helicopter, or where training or demonstrations for the purpose necessitates the actual lifting or lowering of persons, multi- or single engine helicopters may be used. If a multi-engine helicopter is used in operations of this kind, the helicopter need not be capable of hovering out of ground effect with 1 engine inoperative.

8 Rappelling
       8.1The following rappelling operations (restricted rappelling operations):
(a) rappelling operations (other than
