practice and periodical tests as provided in this regulation in respec: of the duties which he is to perform and the operator is satisfied that such person is competent to perform his duties.
(2) Scheduled journeys
(a) In the case of a flight constituting the whole or part of a scheduled journey, the pilot in charge of the aircraft for the flight shall within the relevant period have been tested by or on behalf of the operator—
(i) as to his knowledge of the route to be taken, the aerodromes of take-off and landing, and any alternate aerodromes, including in particular his knowledge of-
the terrain,
the seasonal meteorological conditions,
the meteorological, communications, and air traffic
facilities, services and procedures, the search and rescue procedures, and the navigational facilities
relevant to the route;
(i) as to his proficiency in using instrument approach. to-land systems of the type in use at the aerodrome of intended landing and any alternate aerodromes, such lest being carried out either in flight or by means of apparatus of approved type in which flight conditions are simulated on the ground, and in IFR conditions which may in the case of tests carried out in flight be simulated.
(6) In determining whether a person's knowledge of the
matters referred to in sub-paragraph (aXI) is sufficient render him competent to perform the duties of pilot in charge of the aircraft on the flight, the operator shall take into account the person's flying experience of the route in conjunction with the following factors--
(1) the influence of terrain and obstructions on depar ture and approach procedures at the aerodromes of take- off and intended landing and at alternate aerodromes:
(ii) the similarity of the instrument approach proce dures and let-down aids to those with which the person is familiar;
(ii) the dimensions of runways which may be used in the course of the flight in relation to the performance limits of aircraft of the type to be used on the fight:
(iv) the reliability of meteorological forecasts and the i probability of difficult meteorological conditions in th areas to be traversed;
}}
(v) the adequacy of the information available regard- ing the aerodrome of intended landing and any alternate aerodromes:
(vi) the extent of the assistance obtainable en route from navigational aids and air to ground communication facilities:
(vii) the extent to which it is possible for the person to become familiar with unusual aerodrome procedures and features of the route by means of ground instruction and training devices.
(3) Non-scheduled journeys
In the case of a flight which does not constitute the whole or any part of a scheduled journey, the pilot in charge of the aircraft for the flight shall within the relevant period have been tested by or on behalf of the operator-
(i) as to his knowledge of-
the terrain.
the seasonal meteorological conditions,
the meteorological, communications, and air traffic
facilities, services and procedures.
the search and rescue procedures, and the navigational facilities
relevant to the route;
(i) as to his proficiency in using instrument approach-to-land systems of the type in use at the aerodrome of intended landing and any alternate aerodromes, such test being carried out either in flight or by means of apparatus of approved type in which flight conditions are simulated on the ground, and in IFR conditions which may in the case of tests carried out in flight be simulated.
