Grooved or porous friction course runway. A paved runway that has been constructed and maintained with lateral grooving or a porous friction course (PFC) surface to improve braking characteristics when wet in compliance with the Aerodrome Design Manual (Doc 9157) or equivalent. 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 manual, 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. Human Factors principles. Principles which apply to aeronautical design, certification, training, operations and maintenance and which seek safe interface between the human and other system components by proper consideration to human performance. Human performance. Human capabilities and limitations which have an impact on the safety and efficiency of aeronautical operations. Landing distance available (LDA). The length of runway which is declared available and suitable for an aeroplane landing. Note.— This definition differs slightly from the definition in Annex 6, specifically for the purposes of this manual. 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. Manufacturer. The organization responsible for the type design that holds the type certificate, or equivalent document, for an aircraft issued by a Member State. Maximum mass. Maximum certificated mass. Note.— This definition differs slightly from the definition in Annex 6, specifically for the purposes of this manual. 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). NOTAM. A notice distributed by means of telecommunication containing information concerning the establishment, condition or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to personnel concerned with flight operations. Obstacle clearance altitude (OCA) or obstacle clearance height (OCH). The lowest altitude or the lowest height above the elevation of the relevant runway threshold or the aerodrome elevation as applicable, used in establishing compliance with appropriate obstacle clearance criteria. Note 1.— Obstacle clearance altitude is referenced to mean sea level and obstacle clearance height is referenced to the threshold elevation or in the case of non-precision approach procedures to the aerodrome elevation or the threshold elevation if that is more than 2 m (7 ft) below the aerodrome elevation. An obstacle clearance height for a circling approach is referenced to the aerodrome elevation. Note 2.— For convenience when both expressions are used they may be written in the form “obstacle clearance altitude/height” and abbreviated “OCA/H”. Operations manual. A manual containing procedures, instructions and guidance for use by operational personnel in the execution of their duties. Operations specifications. The authorizations, conditions and limitations associated with the air operator certificate and subject to the conditions in the operations manual. Operator. The person, organization or enterprise engaged in or offering to engage in an aircraft operation. Pressure-altitude. An atmospheric pressure expressed in terms of altitude which corresponds to that pressure in the Standard Atmosphere. Reference humidity. The relationship between temperature and reference humidity is defined as follows: |
