d) Landing distance available (LDA). The length of runway which is declared available and suitable for the ground run of an aeroplane landing. Note.— The calculation of declared distances is described in Annex 14, Volume I, Attachment A. Declared temperature. A temperature selected in such a way that when used for performance purposes, over a series of operations, the average level of safety is not less than would be obtained by using official forecast temperatures. Expected. Used in relation to various aspects of performance (e.g. rate or gradient of climb), this term means the standard performance for the type, in the relevant conditions (e.g. mass, altitude and temperature). Height. The vertical distance of a level, a point, or an object considered as a point, measured from a specified datum. Note.— For the purposes of this example, the point referred to above is the lowest part of the aeroplane and the specified datum is the take-off or landing surface, whichever is applicable. Landing surface. That part of the surface of an aerodrome which the aerodrome authority has declared available for the normal ground or water run of aircraft landing in a particular direction. Net gradient. The net gradient of climb throughout these requirements is the expected gradient of climb diminished by the manoeuvre performance (i.e. that gradient of climb necessary to provide power to manoeuvre) and by the margin (i.e. that gradient of climb necessary to provide for those variations in performance which are not expected to be taken explicit account of operationally). Reference humidity. The relationship between temperature and reference humidity is defined as follows: — at temperatures at and below ISA, 80 per cent relative humidity, — at temperatures at and above ISA + 28°C, 34 per cent relative humidity, — at temperatures between ISA and ISA + 28°C, the relative humidity varies linearly between the humidity specified for those temperatures. Take-off surface. That part of the surface of an aerodrome which the aerodrome authority has declared available for the normal ground or water run of aircraft taking off in a particular direction. TAS (True airspeed). The speed of the aeroplane relative to undisturbed air. Note.— See Chapter 1 and Annexes 8 and 14, Volume I, for other definitions. 2. Take-off 2.1 Mass The mass of the aeroplane at take-off is not to exceed the maximum take-off mass specified in the flight manual for the altitude and temperature at which the take-off is to be made. 2.2 Performance The performance of the aeroplane, as determined from the information contained in the flight manual, is such that:
