Meteorological service is provided within the Yerevan FIR.
3.1 Yerevan “Zvartnots” aerodrome.

Screw anemometers 300 m FM THR RWY 27 and 09 Height 6 m. Screw anemometers on the tower (height 70 m). RVR equipment: Transmissiometers 300 m FM THR RWY and near the middle section of runway. Ceilometers: 300 m FM THR RWY and ceilometers at a distance about 1000 m from the threshold. Thermometer and humidity sensors: at the meteorological park. | H24 | Climatological tables AVBL |
3.2 Gyumri “Shirak” aerodrome.

| Gyumri/Shirak UDSG | Special obs, Half hourly KRAMS-2 (ARCMS-2) | METAR, SPECI, TREND | SFC wind sensors: screw anemometers 300 m FM THR RWY 02 (Height 10 m). Screw anemometers Height 30 m. RVR equipment transmissiometers 300 m FM THR RWY. Ceilometers: 300 m FM THR RWY and ceilometers at a distance about 1400 m from the threshold. Thermometers and humidity sensors: at the meteorological park. | H12 | Climatological tables AVBL |
Surface wind is measured by wind sensors located at the meteorological park at a lateral distance of 120 m from the runway center line and at the height of 10 m above the ground.
Near this sensor installed other wind sensor at the height of 30 m above the ground.
Visibility on RWY is measured by transmissiometers located near THR at the both end of the runway.
When the horizontal visibility is less than 1500 m (1000 m during twilight), transmissiometers values are transformed to RVR by using tables for different levels of runway edges lights.
The height of the cloud base is measured by celiometers, installed near the threshold and at a distance about 1400m. from the threshold.
Sensors placed at the meteorological park define temperature and dew point.
Wind shear is defined by:
wind sensor installed near the meteorological park (height 30 m);
balloon;
information received from aircraft reports.
3.3 “Stepanavan” aerodrome.
| Name of station/Location indicator | Type & frequency of observation/automatic observing equipment | Types of MET reports & Supplementary Information included | Observation System & Site(s) | Hours of operation | Climatological information |
|---|---|---|---|---|---|

| Stepanavan UDLS | Special obs. Half hourly, NIL | METAR, SPECI, TREND | SFC wind sensors: Screw anemometers 56 m FM THR RWY Height 6 m. Screw anemometers on the airport building Height 10 m. Screw anemometers on the TV tower Height 340 m. Ceilometers: 110 m FM the RWY centerlines. Thermometer in the meteorological box. | H12 | Climatological tables AVBL |
Surface wind is measured by wind sensors located near the runway at a lateral distance 56 m from the runway centerline and at the height 6 m above the ground.
Wind sensors are installed also on the airport building at the height 10 m above the ground and on the TV tower height 340 m.
Visibility on RWY is defined visually, by visibility orientirs.
The height of the cloud base is measured by celiometers, installed near the building at a distance about 110 m from the runway centerline.
Thermometers placed at the meteorological box are defined temperature and dew point.
-
Wind shear is defined by:
wind sensor installed on TV tower height 340 m;
information received from aircraft reports.
The flight documentation comprises a significant weather chart, upper wind and upper air temperature chart, and the latest available aerodrome forecast, actual weather for the destination and for alternate aerodromes.
Aerodrome actual weather reports, and aerodrome forecasts are issued as listed in Table GEN -3.5.3.1 and the respective AD-part.
Area forecast for low-level flights including under VFR, operating below FL 150 (572 hPa) within Yerevan FIR is issued by Meteorological Center.
The low-level forecast contains the following information (as indicated Annex3, item 6.6.2):
Special features of the meteorological situation, significant weather phenomena as specified for low level flights, surface visibility, clouds, (height of cloud base is given above the sea level), frizzing level, minimum QNH, upper winds and upper-air temperatures.
The flight documentation comprises a significant weather chart, upper wind and upper air temperature chart, the latest available aerodrome forecast, actual weather for the destination and for alternate aerodromes.
The notification required from operators is provided in accordance with the ICAO Annex 3part 2.3.
Aircraft observation are made during flight within Yerevan FIR as well as during the climb-out or approach phases of flight regarding to all weather phenomena, which in opinion of pilot-in-command may affect safety and the efficiency of other aircraft operation or are not accurately forecasted.
Aircraft meteorological observations shall be reported to appropriate ATS units as soon as practicable.
Aircraft crew shall always report icing (irrespective of intensity), moderate or severe turbulence and wind shear encountered, even if previously reported to the aircraft. Observations, which have not been possible to report during the flight, shall be reported as soon as practicable on arrival.

Note: SIGMET information for aerodrome Stepanavan is composes by the meteorological division of aerodrome “Shirak”.
For the safety of air traffic, the Meteorological Authority maintains an area meteorological watch and warning service. This service consists partly of a continuous weather watch within the lower and upper FIR and the issuance of appropriate information (SIGMET) by Meteorological Watch Offices and partly of the issuing of warnings for the respective aerodrome and, subject to agreement, for other aerodromes by all aeronautical MET offices.
