Multi-engined aeroplanes: (a) two pilot operated; or (b) single pilot operated multi-engine turbo-jets or (operative) auto-feather equipped.
IFR aeroplanes above 5,700 kg. With runway edge lighting (light spacing not more than 60 metres) and either runway centreline lighting or centreline marking. |
0 0 |
800 metres 500 metres
|
Multi-engined aeroplanes: (a) two pilot operated; or (b) single pilot operated turbo-jets or (operative) auto-feather equipped.
IFR aeroplanes not above 5,700 kg, capable of a gross climb gradient of at least 1.9% under ambient conditions with the loss of the most critical engine With runway edge lighting (light spacing not more than 60 metres) and either runway centreline lighting or centreline marking.

All other IFR helicopters | 500 ft | 800 metres |
(2) The meteorological minima for aircraft landing are:
(a) for aerodromes with an approved instrument approach procedure — the minima specified in the instrument approach chart for carrying out that procedure, being a decision height of not less than 200 feet and visibility of not less than 800 metres; or
(b) for other aerodromes:
(i) in the case of day IFR — visual approach requirements; and
(ii) in the case of night IFR — VMC from the lowest safe altitude within 3 nautical miles.
(3) The meteorological minima for aircraft taking off or landing are subject to specific minima set out in aerodrome charts issued for individual aerodromes.
