2 000 feet AMSL but flight visibility shall be not less than 20 kilometres.Additionally, flight conditions shall be such that there is sufficient celestial illumination to provide a discernible true horizon.
3.6 Operations under the provisions of this section shall be conducted over water and at a minimum distance of 20 nautical miles from land (including islands) or obstacles having a height greater than 300 feet above sea level.
3.7 The following operating procedures and parameters shall apply:
         (a) before descent below lowest safe altitude, the flight crew shall:
 (i) complete the low flying checklist; and
 (ii) disengage the autopilot; and
 (iii) set pressure altimeters to the lowest forecast QNH in the operating area;
         (b) turns below the lowest safe altitude shall be limited to the lesser of 25 degrees of bank, rate 1 or the radio altimeter unlock angle;
         (c) for operations below 1 000 feet AMSL:
 (i) the target is to be in sight before descent below 1 000 feet AMSL is initiated; and
 (ii) maximum rate of descent shall be 500 feet per minute; and
 (iii) for aeroplanes, flap setting shall be not greater than that recommended for take-off or manoeuvring; and
 (iv) for aeroplanes, minimum speed shall be 1.5VS; and
 (v) for helicopters, minimum speed shall be the minimum I.F.R. speed;
         (d) for operations at 500 feet AMSL:
 (i) the altitude reference for 500 feet AMSL shall be derived from the lesser reading of the aircraft radio altimeter and the pilot's pressure altimeter set to the lowest forecast QNH for the operating area; and
 (ii) visual contact with the target is to be maintained at all times;
         (e) the pilot manipulating the flying controls shall concentrate on accurate flying and on accurate positioning of the aircraft for dropping operations;
         (f) a second pilot shall be assigned to monitor the pilot flying the aircraft, in accordance with appropriate crew coordination procedures established by the operator;
         (g) operations below lowest safe altitude shall not be conducted or shall be discontinued if any of the instruments required in accordance with section 20.18, Appendix IV, or section 20.18, Appendix VII as applicable, or the radio altimeter, fail.
