19. Aeronautical meteorological stations and observations
(1)The Authority shall ensure that aeronautical meteorological stations are established at aerodromes as it may deem necessary and such aeronautical meteorological station may be a separate station or combined with a synoptic station.(2)The meteorological service provider shall carry out meteorological observations and issue reports in accordance with the technical specification and detailed criteria set out in the Manual of Implementing Standards-Meteorological Service for Air Navigation.(3)The Aeronautical meteorological stations shall include sensors installed outside the aerodrome, where considered justified, by the meteorological service provider to ensure the compliance of meteorological service for air navigation with the provisions of these Regulations.(4)The meteorological service provider shall establish, or arrange for the establishment of, aeronautical meteorological stations on offshore structures or at other points of significance in support of helicopter operations to offshore structures, if required by regional air navigation agreement.(5)Aeronautical meteorological stations shall make routine observations at fixed time intervals and in case of aerodromes, the routine observations shall be supplemented by special observations whenever specified changes occur in respect of surface wind, visibility, runway visual range, present weather, clouds or air temperature.(6)The meteorological instruments used at an aerodrome shall be situated in such a way as to supply data which are representative of the area for which the measurements are required.(7)Meteorological instruments at aeronautical meteorological stations shall be exposed, operated and maintained in accordance with the practices, procedures and specifications promulgated by the World Meteorological Organization (WMO).(8)The observers at an aerodrome shall be located, in so far as is practicable, to supply data which are representative of the area for which the observations are required.(9)The Authority shall ensure that the meteorological service provider shall arrange for its aeronautical meteorological stations to be inspected at sufficiently frequent intervals to ensure that—(a)a high standard of observation is maintained;(b)that instruments are calibrated and all their indicators are functioning correctly; and(c)that the exposure of the instruments has not changed significantly.(10)Automated equipment shall be installed at aerodromes with runways intended for category II and III instrument approach and landing operations and such equipment shall be for measuring or assessing, monitoring and remote indicating of surface wind, visibility, runway visual range, height of cloud base, air and dew-point temperatures and atmospheric pressure.(11)These devices shall be integrated automatic systems for acquisition, processing, dissemination and display in real time of the meteorological parameters affecting landing and take-off operations.(12)The design of integrated automatic systems shall observe Human Factors principles and include back-up procedures.(13)Where an integrated semi-automatic system is used for the dissemination or display of meteorological information, it shall be capable of accepting the manual insertion of data covering those meteorological elements which cannot be observed by automatic means.(14)The observations shall form the basis for the preparation of reports to be disseminated at the aerodrome of origin and of reports to be disseminated beyond the aerodrome of origin.(15)Where automated equipment forms part of an integrated semi-automatic observing system, displays of data which are made available to the local air traffic services units shall be a subset of and displayed parallel to those available in the local meteorological service unit.(16)The displays in subregulation (15) above, each meteorological element shall be annotated to identify, as appropriate, the locations for which the element is representative.
