NCO.OP.110 Aerodrome operating minima —
aeroplanes and helicopters
(a) For instrument flight rules (IFR) flights,
the pilot-in-command shall establish aerodrome operating minima for each
departure, destination or alternate aerodrome that is planned to be used in
order to ensure separation of the aircraft from terrain and obstacles and to
mitigate the risk of loss of visual references during the visual flight
segment of instrument approach operations.
(b) The aerodrome
operating minima shall take the following elements into account, if relevant:
(1) the type, performance, and handling
characteristics of the aircraft;
(2) the equipment available on the aircraft for the purpose of navigation,
acquisition of visual references, and/or control of the flight path during
take-off, approach, landing, and missed approach;
(3) any conditions or limitations stated in the aircraft flight manual
(AFM);
(4) the dimensions and characteristics of the runways/final approach and
take-off areas (FATOs) that may be selected for use;
(5) the adequacy and performance of the available visual and non-visual
aids and infrastructure;
(6) the obstacle clearance altitude/height (OCA/H) for the instrument
approach procedures (IAPs), if established;
(7) the obstacles in the climb-out areas and clearance margins;
(8) the competence and relevant operational experience of the
pilot-in-command;
(9) the IAP, if established;
(10) the aerodrome characteristics and the type of air navigation services
(ANS) available, if any;
(11) any minima that may be promulgated by the State of the aerodrome;
(12) the conditions prescribed in any specific approvals for low-visibility
operations (LVOs) or operations with operational credits.;
For IFR flights, pilots must establish aerodrome operating minima for departure, destination, and alternate airports. These minima ensure safe terrain clearance and visual reference during instrument approaches. Factors considered include aircraft type, equipment, runway characteristics, navigation aids, obstacle clearance, pilot experience, and any state-defined or low-visibility operation minima.
