d) Landing distance available (LDA). The length of runway which is declared available and suitable for the ground run of an aeroplane landing. Dependent parallel approaches. Simultaneous approaches to parallel or near-parallel instrument runways where radar separation minima between aircraft on adjacent extended runway centre lines are prescribed. Displaced threshold. A threshold not located at the extremity of a runway. Effective intensity. The effective intensity of a flashing light is equal to the intensity of a fixed light of the same colour which will produce the same visual range under identical conditions of observation. Ellipsoid height (Geodetic height). The height related to the reference ellipsoid, measured along the ellipsoidal outer normal through the point in question. Fixed light. A light having constant luminous intensity when observed from a fixed point. Frangible object. An object of low mass designed to break, distort or yield on impact so as to present the minimum hazard to aircraft. Note.— Guidance on design for frangibility is contained in the Aerodrome Design Manual (Doc 9157), Part 6. Geodetic datum. A minimum set of parameters required to define location and orientation of the local reference system with respect to the global reference system/frame. Geoid. The equipotential surface in the gravity field of the earth which coincides with the undisturbed mean sea level (MSL) extended continuously through the continents. Note.— The geoid is irregular in shape because of local gravitational disturbances (wind tides, salinity, current, etc.) and the direction of gravity is perpendicular to the geoid at every point. Geoid undulation. The distance of the geoid above (positive) or below (negative) the mathematical reference ellipsoid. Note.— In respect to the World Geodetic System — 1984 (WGS-84) defined ellipsoid, the difference between the WGS- 84 ellipsoidal height and orthometric height represents WGS-84 geoid undulation. Gregorian calendar. Calendar in general use; first introduced in 1582 to define a year that more closely approximates the tropical year than the Julian calendar (ISO 19108*). Note.— In the Gregorian calendar, common years have 365 days and leap years 366 days divided into twelve sequential months. Hazard beacon. An aeronautical beacon used to designate a danger to air navigation. Heliport. An aerodrome or a defined area on a structure intended to be used wholly or in part for the arrival, departure and surface movement of helicopters. Holding bay. A defined area where aircraft can be held, or bypassed, to facilitate efficient surface movement of aircraft. Holdover time. The estimated time the anti-icing fluid (treatment) will prevent the formation of ice and frost and the accumulation of snow on the protected (treated) surfaces of an aeroplane. 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. Identification beacon. An aeronautical beacon emitting a coded signal by means of which a particular point of reference can be identified. Independent parallel approaches. Simultaneous approaches to parallel or near-parallel instrument runways where radar separation minima between aircraft on adjacent extended runway centre lines are not prescribed. Independent parallel departures. Simultaneous departures from parallel or near-parallel instrument runways. Instrument runway. One of the following types of runways intended for the operation of aircraft using instrument approach procedures:
