| Zusammenfassung |
| Meteorological information is a key factor in aviation, especially in unmanned (UAV) operations where actual intervention is not possible in case of unforeseen weather hazards. For the development of an aviation meteorology system in support of UAV operation, various research activities have been initiated recently in Hungary. This activity included statistical analysis of historical weather data, numerical weather prediction model development and in situ measurements with the UAV airframe itself. The aim of our current presentation is the introduction of the planned meteorological survey system. Model development includes the comparison test of different model setup in various selected meteorological situations (widespread precipitation, strong wind condition, strong inversions, significant wind veering, deep convection, frontal activity, icing, mid-tropopause cold vortex). The output of meteorological forecast model is post-processed for the special needs of aviation, including the forecast of visibility/low cloudbase, icing, turbulence, windshear, etc. The model results can be verified using UAV based measurements. The airframe, which is a special Hungarian development light unmanned aircraft, is also introduced. The first results of measurements and their comparison to model predictions are also presented. |
