16. Heliport or landing location operating minima
(1)The operator shall establish operating minima for each heliport or landing location to be used in operations and the method of determination of such minima shall be approved by the Authority and such minima shall not be lower than any that may be established for such heliports or landing locations by the Authority, except when specifically approved.(2)The Authority may approve operational credit(s) for operations with helicopters equipped with automatic landing systems, a HUD or equivalent displays, EVS, SVS or CVS. Such approvals shall not affect the classification of the instrument approach procedure. Operational credit includes-(a)for the purposes of an approach ban; a minima below the heliport or landing location operating minima;(b)reducing or satisfying the visibility requirements; or(c)requiring fewer ground facilities as compensated for by airborne capabilities.(3)The Authority shall require that in establishing the operating minima for each heliport or landing location which will apply to any particular operation, full account shall be taken of—(a)the type, performance and handling characteristics of the helicopter;(b)the composition of the flight crew, their competence and experience;(c)the physical characteristics of the heliport, and direction of approach;(d)the adequacy and performance of the available visual and non-visual ground aids;(e)the equipment available on the helicopter for the purpose of navigation, acquisition of visual references and/or control of the flight path during the approach, landing and missed approach;(f)the obstacles in the approach and missed approach areas and the obstacle clearance altitude/height for the instrument approach procedures;(g)means used to determine and report meteorological conditions; and(h)the obstacles in the climb-out areas and necessary clearance margins.(4)Instrument approach operations shall be classified based on the designed lowest operating minima below which an approach operation shall only be continued with the required visual reference as follows—(a)Type A: a minimum descent height or decision height at or above 75 m (250 ft): and(b)Type B: a decision height below 75 m (250 ft). Type B instrument approach operations are categorized as—(i)Category I (CAT I): a decision height not lower than 60 m (200 ft) and with either a visibility not less than 800 m or a runway visual range not less than 550 m;(ii)Category II (CAT II): a decision height lower than 60 m (200 ft), but not lower than 30 m (100 ft) and a runway visual range not less than 300 m;(iii)Category IIIA (CAT IIIA): a decision height lower than 30m (100 ft) or no decision height and a runway visual range not less than 175 m;(iv)Category IIIB (CAT IIIB): a decision height lower than 15m (50 ft). or no decision height and a runway visual range less than 175 m but not less than 50 m; and(v)Category IIIC (CAT IIIC): no decision height and no runway visual range limitations.(5)Category II and Category Ill instrument approach operations shall not be authorized unless RVR information is provided.(6)The operating minima for 2D instrument approach operations using instrument approach procedures shall be determined by establishing a minimum descent altitude (MDA) or minimum descent height (MDH), minimum visibility and, if necessary, cloud conditions.(7)The operating minima for 3D instrument approach operations using instrument approach procedures shall be determined by establishing a decision altitude (DA) or decision height (DH) and the minimum visibility or RVR.
