4 TYPES OF SERVICES

The Aerodrome Meteorological Office is located in Hamad International Airport (telephone numbers: (974)40102239; (974)40102238) and provides the following services H24:

  1. Personal briefing and consultation to flight crew members, upon request;
  2. Full meteorological documentation for current operational planning for all flights departing Doha and Hamad International Airports;
  3. Supply of meteorological information to aircraft in flight through DOHA INTL radio channels;
  4. Meteorological information for ATS; and
  5. Information for Search and Rescue Service Units.

Only auto weather station is available at AL KHOR aerodrome and consultation is available by telephone from the Aerodrome Meteorological Office.

Details of documentation supplied for each flight are determined by arrangement between the operator and the Aerodrome Meteorological Office. Flight documentation is normally provided for domestic flights. For international flights, the flight documentation comprises a significant weather chart, an upper wind and upper air temperature chart and the latest available aerodrome forecast for the destination and its alternate aerodromes.

Routine aerodrome forecasts received from other Meteorological Offices are normally included in meteorological documentation without modification. When a required aerodrome forecast is not received, a provisional forecast may be issued by the Meteorological Office providing the documentation.

After documentation has been issued and until take-off, the Aerodrome Meteorological Office makes available amendments to the documentation. It is the responsibility of the operator's local representative to provide pre-departure amendment(s) from the Aerodrome Meteorological Office to the pilot-in- command.

Climatological summaries for DOHA INTL / HAMAD INTL are available from the Aerodrome Meteorological Office.

5 Notification required from operators

Operators requiring meteorological service or changes in existing meteorological services shall notify, sufficiently in advance, to the Department of Meteorology of the Qatar Civil Aviation Authority in accordance with ICAO Annex 3, paragraph 2.3.

Operators or their flight crew members shall notify the Aerodrome Meteorological Office at DOHA INTL / HAMAD INTL, as soon as the following information becomes available:

  1. of flight schedules;
  2. when non-scheduled flights are to be operated; and
  3. when flights are delayed, advanced or cancelled.

6 Aircraft reports

For the benefit of subsequent aircraft and for validation and further enhancement of the low-level wind shear and turbulence alerting services, pilots are requested to inform ATC if they experience any microburst, wind shear or turbulence on arrival or departure, irrespective of whether an alert has been given. ATC will pass such reports to following aircraft.

Further to the pilot reporting of low-level wind shear and turbulence at DOHA INTL / HAMAD INTL airports, pilots are requested to pass special aircraft observation as soon as possible to the appropriate ATS unit by voice communications whenever any of the following conditions are encountered or observed:

  1. severe turbulence;
  2. severe icing;
  3. thunderstorm, without hail (obscured, embedded, widespread or in squall lines);
  4. thunderstorms, with hail (obscured, embedded, widespread or in squall lines); and
  5. heavy dust storm or heavy sand storm.

When other meteorological conditions not listed above are encountered and which, in the opinion of the pilot-in-command, may affect the safety or markedly affect the efficiency of other operations, the pilot-in-command shall advise ATC as soon as practicable.

Aircraft observations shall be reported as air-reports following the instructions in ICAO PANS-ATM (Doc 4444) - Appendix 1.
