schedule or fight manual relating to the aeroplane issued or rendered valid by the Director, is capable of attaining a height of 50 feet within the following distance-
() if the aeroplane has one or two engines-the lake- of run available or 75 per cent. of the emergency distance available, whichever is the less, at the aerodrome at which the take-off is to be made;
(ii) if the aeroplane has more than two engines-the take-off run available or 85 per cent. of the emergency distance available, whichever is the less, at the aerodrome a which the take-off is to be made:
(c) the weight at which the aeroplane, with all engines operating within the maximum take-off power conditions specified in the certificate of airworthiness, performance schedule or flight manual relating to the aeroplane issued or rendered valid by the Director, is, after passing the end of the emergency distance available, capable of clearing 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 aeroplane does not exceed 200 feet plus half the wing span of the aeroplane.
(3) The aeroplane will, in the metromlogical conditions expected for the flight in the event of one engine becoming inoperative at any point on its route or on any planned diversion therefrom and with the other engine or engines, if any, operating within the maximum continuous power conditions specified in the certificate of airworthiness, performance schedule or flight manual relating to the aeroplane issued or rendered valid by the Director, be capable of continuing the flight so as to reach a point above—
(a) an aerodrome at which a safe landing can be made at a
suitable height for such landing; or
(b) if the aeroplane has a maximum total weight authorized in its certificate of airworthiness not exceeding 12,500 lb. and complies with either condition (1)(a) or condition (1)(6) hereof, a place at which a safe landing can be made ar a suitable height for such landing,

(4) The aeroplane will, in the meteorological conditions expected for the flight, at any point on its route or on any planned diversion therefrom, be capable of climbing at a gradient of at least 1 in 50, with all engines operating within the maximum continuous power conditions specified in the certificate of air- worthiness, performance schedule or flight manual relating to the aeroplane issued or rendered valid by the Director, at the follow- ing altitudes-
(a) the minimum altitudes for safe flight on each stage of the route to be flown or of any planned diversion there- from stated in, or calculated from the information con- tained in, die operations manual;
(b) the minimum altitudes on each stage of the route to be flown or of any planned diversion therefrom at which it is necessary to fly to ensure that, in the event of one engine becoming inoperative and with the other engine or engines, if any, operating within the maximum con- tinuous power conditions specified in the certificate of airworthiness, performance schedule or flight manttal relating to the aeroplane issued or rendered valid by the Director, the aeroplane is capable of continuing the flight so as to reach a point abov
(i) an aerodrome at which a safe landing can be made at a height suitable for such landing; or
(ii) if the aeroplane has a muximum total weight authorized in its certificate of airworthiness not excceding 14,500 Th., and complies with either condition (0)(4) or condition (1)(5) hereof, a place at which a safe landing can be made at a height suitable for such landing.
(3) If on the route to be flown the aeroplane will be engaged in a flight over water during which at any time it may be more than go minutes flying time in still air from the nearest shore, it will, in the event of one engine becoming inoperative during such time and with the other engine or engines, if any, operating within the maximum continuous power conditions specified in the certificate of airworthiness, performance schedule or light manual relating to the aeroplane, issued or rendered valid by the Director, be capable of climbing at a gradient of at least in 200, at an altitude of 5.0on feet above mean sea level in air having a tem- perature of 5.1° centigrade and a pressure of 843 millibars.
