Regulation 35
Aerodrome operating minima — determination
Subregulation 1
A CGAC holder must establish aerodrome operating minima for every aerodrome that is selected as a departure, destination or alternate aerodrome for its complex general aviation operations.
Subregulation 2
A CGAC holder must specify in its Operations Manual —
the aerodrome operating minima for every aerodrome mentioned in paragraph (1); and
the method used to determine the aerodrome operating minima.
Subregulation 3
The method of determination mentioned in paragraph (2)(b) must involve the consideration of the following matters:
the type, performance and handling characteristics of the aircraft and any relevant conditions in the aircraft’s Certificate of Airworthiness;
the composition of the flight crew, their competence and experience;
the dimensions and characteristics of each runway or helipad which may be selected for use;
the adequacy and performance of the available visual and non‑visual ground aids;
the equipment available on the aircraft for the purpose of navigation, acquisition of visual references or control of the flight path during the approach to landing and the missed approach;
the obstacles in the approach and missed approach areas and the obstacle clearance altitude or height for the instrument approach procedures;
the means used to determine and report meteorological conditions;
any obstacles in the climb‑out areas and necessary clearance margins.
Subregulation 4
For the purpose of establishing the aerodrome operating minima of any aerodrome mentioned in paragraph (1), the CGAC holder may use the operating minima specified for that aerodrome in a commercially available flight guide unless the specified operating minima is lower than that established using the method of determination specified in the CGAC holder’s Operations Manual.
Subregulation 5
The aerodrome operating minima determined in accordance with the method specified in paragraph (3) for a selected aerodrome must not be lower than the aerodrome operating minima that is established for that aerodrome by the State of the Aerodrome, except in any particular case where the State of the Aerodrome has specifically approved the CGAC holder’s use of a lower aerodrome operating minima.
Subregulation 6
A CGAC holder must not use any head‑up display, enhanced vision system, synthetic vision display, or combined vision system, where equipped, to gain operational credits for operations in conditions of lower visibilities than normally associated with the aerodrome operating minima, except under and in accordance with an approval granted by the Director‑General of Civil Aviation under the Air Navigation (98 — Special Operations) Regulations 2018 (G.N. No. S 442/2018) for that purpose.
Subregulation 7
A CGAC holder must not use aerodrome operating minima lower than Category I except under and in accordance with an approval granted by the Director‑General of Civil Aviation under the Air Navigation (98 — Special Operations) Regulations 2018 for that purpose.
Subregulation 8
In this regulation, “aerodrome operating minima” includes the minimum weather conditions appropriate to each set of circumstances which can be reasonably expected at every runway or helipad that may be selected for use.
