group D shall not fly or attempt to fly unless the weight of the acroplane at the commencement of the take-off run is such that the following conditions are satisfied-

(1) Such weight does not exceed the maximum take-off weight ascertained by reference to the flight manual relating to the aero- plane issued or rendered valid by the Director as being appropriate to the height above mean sea level of and the air temperature al the aerodrome at which the take-off is to be made.

(2) The take-off run required and the take-off distance required ascertained by reference to the said flight manual as being appropriate to-

(a) the weight of the aeroplane at the commencement of the

take-off run

(b) the height above mean sea level of the aerodrome;

(c) either the air temperature at the time of take-off or a temperature approved in respect of the aerodrome by the Director:

(d) the average slope of the surface of the aerodrome in the direction of take-off over the emergency distance avail- able;

(e) not more than 50 per cent. of the reported wind co01- ponent opposite to the direction of take-off or not less than 150 per cent. of the reported wind component in the direction of take-off;

do not exceed the take-off run available and the emergency distance available, respectively, at de aerodrome at which the take-off is to be made.

(a) (a) The net take-off flight path with all power units operating, ascertained by reference to the said (light manual as being appropriate to

(i) the weight of the aeroplane at the commencement of the Lake-off run;

(ii) the height above mean sea level of the aerodrome; (iii) either the air temperature at which the take-off is to be made or a temperature approved in respect of the aerodrome by the Director;

(iv) not more than 30 per cent. of the reported wind component opposite to the direction of take-off or not less than 150 per cent. of the reported wind component in the direction of take-oft;

and plotted from a point 50 feet above the end of the take-off distance required at the aerodrome at which the take-off is to be made to the point at which the aeroplane reaches the minimum altitude for safe flight on the first stage of the route to be flown stated in or calculated from the information contained in the operations manual, shows that the aeroplane will clear by a safe margin any obstacle the distance from which to the nearest point on the ground below the intended line of flight of the acroplane does not exceed 200 feet plus half the wing span of the aeroplane,

(b) To assessing the ability of the aeroplane to satisfy this condition it shall not be assumed to make a change of direction of a radius less than the radius of steady turn specified in the said fight manual,

(4) The aeroplane will, if it is classified in its certificate of airworthiness as an aeroplane of performance group C and if it is necessary for it to be flown solely by reference to instruments for any period before reaching the minimum altitude for safe flight on the first stage of the route to be flown, stated in, or calculated from the information contained in, the operations manual, during such period also satisfy condition (3) of regulation 36.

(5) The aeroplane will, in the meteorological conditions expected for the flight, in the event of any one power unit becom- ing inoperative at any point on its route or on any planned diver- sion therefrom, and with the other power units or power unit, if any, operating within the maximum continuous power conditions specified in the said flight manual-

(a) in the case of an aeroplane classified as an aeroplane of performance group C, be capable of continuing the flight at altitudes not less than the relevant minimum altitudes for safe fight stated in, or calculated from the informa- tion contained in, the operations manual to a poim 1,500 feet above an aerodrome at which a safe landing can be made and after arrival at that point be capable of main- taining that height:
