The services are provided in accordance with the provisions contained in the following ICAO documents:
The meteorological service is provided for the Budapest FIR.
Meteorological observations and reports from aeronautical meteorological stations are provided and disseminated according to ICAO Annex 3 regulations.
Flight Weather Observation will be executed depending on personal availabilities as follows:

Fundamental differences AUTO OBS opposite HUMAN OBSFundamental differences HUMAN OBS versus AUTO OBS:
No differences AUTO OBS opposite HUMAN OBS consist of:
Differences and limitations of AUTO OBS opposite HUMAN OBS can be found at:
AUTO OBS determines the MET VIS by point measurement with forward-scattered light measurement equipment at the TDZ and extrapolating the measured values of up toforward-scatter-instruments to the TDZ and MID positions and extrapolating the measured values of up to 20 KM. The required summary values are calculated and reported in accordance with ICAO requirements.
HUMAN OBS determines the visual reference to visual targets in the area.
For RVR, there is no difference, as this is determined both HUMAN OBS and AUTO OBS by measuring the forward scattered light measurement systems and calculation.
DRSN, BLSN and more, in Hungary very rare phenomena in Hungary such as SQ, SA, SS, DU, FU, FC cannot be reported by AUTO OBS.
VC weather phenomena in the environment (Vicinity):
- VCTS may be reported by AUTO OBS
- VCSH and VCFG are not recognized
Clouding phenomena (FG, BR, HZ) isare detected in AUTO OBS by the sensor. Algorithms ensure consistency with the sight. Deviations between AUTO and HUMAN OBS can occur (e.g. BCFG, PRFG) if, for example, fog occur beside the sensors.
FZFG is in the AUTO OBS according ICAO detected by checking with the air temperature, i.e., from T < -0.5 °C FZ is reported.
Rare manifestations (SQ, SA, SS, DU, FU, FC) are not recorded and reported according to visibility as FG, BR or HZ.
With regard toRegarding precipitation some rare phenomena are not specified by the sensors. If detected, these other genera are assigned.
Comparisons have shown that is to be expected with the following differences between HUMAN OBS and AUTO OBS is to be expected:
AUTO OBS recognizedrecognizes thunderstorm TS and VCTS. The data from Weather radar and lightning detection systems are used. The recording quality is good, but itthere may occasionally be incorrect detections by situatebecause of wrong positioning of lightnings and unregistered lightning discharges come.
The perception of visual and acoustic observations (thunder and lightning) is given at HUMAN OBS with greater reliability in detecting the near thunderstorms and the redundancy of the system components fail.
The lack of coverage of SQ in AUTO OBS is mitigated by the availability of current wind data.
- TCU, CB can be determined from AUTO OBS
- coverage is calculated by algorithm
Ceilometers are positioned in the areas where the approach path intersects the relevant IFR approaches decision height. The measurement of the lower limit is determined by point measurement (principle laser gun).
Cloudiness is therefore only recorded in the AUTO OBS, when clouds appear above the sensors.
Cloud cover (FEW, SCT, …): Calculation using algorithms based on all existing airport environmental sensors. From the period duration of the ceilometer detecting the presence of cloud amount is extrapolated:
CB and TCU clouds are detected by weather radar and lightning detection system. The degree of coverage and the amountheight of cloud base, however, cannot be determined automatically. Therefore, it is reported in AUTO OBS as ///.
SKC is not reported: AUTO OBS reports “NCD = no cloud detected” when no clouds are detected by the sensors.
CAVOK is reported in AUTO OBS.
Comparisons have shown that in rare cases groups of clouds are reported FEW001 or FEW002 by false detections of the sensors in the AUTO OBS in rare cases, although no clouds although there are no clouds.there are present. This may affect the classification of VMC, IMC and LVP, if it is not caught by Tower Observations or manual corrections.
The system for the production and distribution of AUTO METAR is monitored REMOTE by MET and centrally by the technical service of Hungarian Meteorological Service. In case of technical failure of individual sensor, the missing data are replaced by slashes as usual in AUTO reports.
Monitoring of the AUTO OBS messages is effected REMOTE by the MET and centrally by the technical service of the Hungarian Meteorological Service.
Technical failures of AUTO OBS system:
Sensor failures:
Network and computer failures lead to the fact that no AUTO OBS weather reports are created and/or distributed. Following actions are planned for these cases:
