4   Types of services

Flight documentation is provided to all aircraft for international flights. The documentation normally contains aerodrome forecasts(TAF code form), significant weather forecasts, upper wind and temperature charts and SIGMET/AIRMET information received from the World Area Forecast System or produced by the AMO

For domestic flights and helicopter operations, the latest aerodrome reports (METAR, SPECI), and aerodrome forecasts, aerodrome warnings and wind shear warnings, area forecasts for low-level flights and SIGMET/AIRMET information are provided for the domestic and international airports, as well as nation-wide area concerned.

The meteorological information is provided via AFTN, fax and the Internet. When the internet service of flight documentation and other additional or specific information are needed, there must be an agreement between the AMO and users.

Briefing and consultation of meteorological information are, in general, provided by each meteorological office/station at the airport. However, when the local circumstances make it impracticable, the briefing and consultation shall be carried out by the AMO through telephone or e-mail.

Area forecasts are issued by the AMO and disseminated through the AMO website for only domestic use.

5   Notification required from operators
5 Notification Required from Operators

The operator or a flight crew member requiring service (flight documentation) shall notify the AMO one day in advance, when :

  1. new routes or new types of operation are planned;

  2. changes are to be made in the scheduled operations;

  3. other changes, affecting the provision of meteorological service, are planned.

The operator or a flight crew member shall notify the AMO at least 6 hours before the expected time of departure, when :

  1. non-scheduled flights are to be operated;

  2. flights are delayed, advanced or cancelled.

  3. flight schedules

6   Aircraft reports
6 Aircraft Reports

When air-ground data link is used and automatic dependent surveillance - contract (ADS-C) or secondary surveillance radar (SSR) Mode S is being applied, automated routine observations should be made every 15minutes during the en-route phase and every 30 seconds during the climb-out phase for the first 10 minutes of the flight. However, when voice communications are used and air-ground data link. ADS-C, SSR Mode reports are not available, routine aircraft observations (AIREPs) are required at the meteorological reporting points in the Asia/Pacific region.

8.1  General

For the safety of air traffic, the Aviation Meteorological Office(AMO), as the Meteorological Watch Office(MWO), maintains a continuous watch over meteorological conditions affecting flight operations within the Incheon FIR and when necessary, issues the SIGMET and AIRMET information, aerodrome warnings and wind shear warnings.

8.2  Meteorological Watch

The meteorological watch is performed by the AMO, as follows:

  1. maintain watch over meteorological conditions affecting flight operations within its area of responsibility

  2. prepare SIGMET and other information relating to its area of responsibility

  3. supply SIGMET information and, as required, other meteorological information to associated air traffic services units

  4. disseminate SIGMET and AIRMET information

  5. supply information received on pre-eruption volcanic activity, a volcanic eruption and volcanic ash cloud for which a SIGMET has not already been issued, to its associated ACC/FIC, as agreed between the meteorological and ATS authorities concerned, and to its associated VAAC as determined by regional air navigation agreement and

  6. supply information received concerning the accidental release of radioactive materials into the atmosphere, in the area for which it maintains watch or adjacent areas, to aeronautical information service units and ATS authorities, as agreed between the meteorological and ATS authorities concerned.

The AMO issues SIGMET and AIRMET information in accordance with ICAO Annex 3, Chapter 7.

8.3  Aerodrome Warnings and Wind shear Warnings

Aerodrome warnings for the protection of parked aircraft or of other equipment at the airport are issued by the AMO or each airport meteorological office concerned, if one or several of the following phenomena are expected to occur at the airport.

  1. Typhoon

  2. Thunderstorm

  3. Hail

  4. Heavy snow

  5. Strong surface wind and gusts

  6. Frost

  7. Tsunami

  8. Low visibility

  9. Heavy rain

  10. Ceiling

  11. Low visibility

  12. Rising sand or dust

  13. Freezing precipitation

  14. Frost

  15. Volcanic ash

  16. Volcanic ash deposition

  17. Toxic chemicals

Wind shear warnings are issued when wind shear which could adversely affect aircraft on the approach path or take off path or during circling approach between runway level and 500 m(1 600 ft) above that level is observed or expected.

The aerodrome warnings and wind shear warnings are issued in English and are distributed in accordance with a distribution list agreed upon locally.
