or unit operating within the maximum continuous power conditions specified, be capable of continuing the flight clearing obstacles within 10 nautical miles either side of the intended track by a vertical interval of at least- (a) 1,000 feet when the gradient of the flight path is not less than zero, or (8) 2,000 feet when the gradient of the flight path is less than zero,

to an aerodrome at which it can comply with condition 9, and on arrival over such aerodrome the flight path shall have a positive gradient of not les than 1 in 200 at 1,500 Izet sbove the aerodrome."

6. 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 power units operating within the maximum continuous power conditions specified, at the following allitudes

(a) the minimum altitudes for safe flight on each stage of the route to be flown or of any planned diversion therefrom specified in, or calculated from the information contained in, the operations manual relating to the aeroplane: and

(6) the minimum altitudes necessary for compliance with conditions 5 and 7.

as appropriate,

7. If on the route to be flown or any planned diversion therefrom, the aero- plane will be engaged in a flight över water during which at any point it may be more than 90 minutes flying time in still air from the nearest shore. it will, in the event of two power units becoming inoperative during such time and with the other power units or unit operating within the maximum continuous power conditions specified, be capable of continuing the flight having regard to the meteorological conditions expected for the fight, clear ing all obstacles within 10 nautical miles either side of the intended track by a vertical interval of at leası 1,000 feel to an aerodrome at which a wit landing can be made.

8. The landing weight of the aeroplane will not exceed the maximum landing weight, if any, specifled for the altitude and the expected air temperature for the estimated time of landing at the aerodrome at which it is intended to land and at any alterate aerodrome,

9. The distance required by the aeroplane to land from a height of 50 feet dosa not, at the aerodrome at which it is intended to land and at any alternat serodrome, exceed 70 per cent of the landing distance available on-

(i) the most suitable runway for a landing in still air conditions; and (ii) the runway that may be required for landing because of the forecas

wind conditions.

the distance required 10 land from a height of 50 feet being taken to be that appropriate 10—

(a) the landing weight:

(5) the altitude at the aerodrame;

(c) the temperature in the specified international standard atmosphere appr

priate to the altitude at the aerodrome;

(d) (i) a level surface in the case of runways usable in both directions;

(i) the average slope of the runway in the case of runways usable in only one direction; and

(e) (1) still air conditions in the case of the most suitable runway for

landing io still air conditions;

(ii) not more than 50 per cent of the forecast wind compunent opposiz to the direction of landing or not less than 150 per cent of the forecu wind component in the direction of landing in the case of the runway that may be required for landing because of the forecast wind condition!.

10. If the acroplane is engaged in a flight at night or when the cloud ceiling or visibility prevailing at the aerodrome of departure and forecast for the estimated time of landing at the acrodrome of destination or at any alternate aerodrome, are less than 1,000 feet and one mile respectively, it will, with any one of its power units inoperative and the remaining power unit or units operating within the maximum continuous power conditions specified, be capable of climbing at a gradient of at least i in 200 at an altitude of 2,500 feet in the specified international standard atmosphere.

11. (1) The distance required by the aeroplane to attain a height of 50 feet, with all power units operating within the maximum take-off power conditions specified, does not exceed the take-off run available at the aerodrome at which the take-off is to be made.

(2) The distance required by the aeroplane to attain a height of 50 feet, with all power units operating within the maximum take-off power conditions specified, when multiplied by a factor of 1.33 does not exceed the emergency distance available at the aerodrome at which the take-off is to be made.

(3) For the purposes of paragraphs (1) and (2) the distance required by the deroplane to attain a height of 50 feet shall be that appropriate to--

(a) the weight of the aeroplane at the commencement of the take-off run (b) the altitude at the aerodrome;

(c) the temperature in the specified international standard atmosphere appro- priate to the altitude at the uerodrome, or, if greater, the air temperature it the aerodrome less 15" Centigrade;

(d) the slope of the surface of the aerodrome in the direction of take-off over the take-off run available and the emergency distance available, respectively; and

(e) not more than 50 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-off.

12. The take-off flight path, with all power units operating within the maximum

take-off power conditions specified, appropriate "to-

(a) the weight of the aeroplane at the commencement of the lake-off run; (6) the altitude at the aerodrome;

(c) the temperature in the specified international standard atmosphere appro- priate to the altitude at the aerodrome, or, if greater, the air temperature at the aerodrome less 15° Centigrade; and

(c) not more than 50 per cent of the reported wind component opposite 19 the direction of take-off or not less than 150 per cent of the reported wind component in the direction of take-off,

und plotted from a point 50 feet above the end of the factored distance required for take-off under paragraph (2) of condition 11, at the aerodrome at which tho take-off is to be made, shows that the aeroplane will clear any obstacle lying within 200 feet plus half the wing span of the aeroplane on either side of its path by a vertical interval of at least 35 feet. In 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 a radius of steady tura corresponding to an angle of bank of 15".

13. The aeroplane will, in the meteorological conditions expected for the fight, in the event of any one power unit becoming inoperative at any point on its route or on any planned diversion therefrom and with the other power unit or unita, if any, Operating within the maximum continuous power conditions specified, be capable of continuing the flight so as to reach a point above a place at which a safe landing can be made at a suitable height for such landing.

14. The aeroplane will, in the meteorological conditions expected for the fight, at any point on its route or any planned diversion therefrom, be capable of climbing at a gradient of at least 1 in 50, with all power units operating
