Abstract:
Icing is a hazardous weather phenomenon for aviation. The effect of this phenomenon consists in an accumulation of ice that can affect an aircraft on the ground, during take-off, landing or during flight through clouds, being favored by certain weather conditions. The purpose of this study is to determine the regions in the Romanian airspace where icing situations were reported, their intensity, as well as the meteorological conditions that favored them. The study of meteorological conditions associated with icing involves a deeper knowledge of the responsible phenomena related to the phase transformations of water in the atmosphere, in general, and in clouds, in particular. The study uses the database containing the pilots' reports regarding icing situations encountered during the flight for the period 2019-2020. This database belongs to the management of ROMATSA (Romanian Air Traffic Administration), which deals with the provision of air traffic services, aeronautical meteorological services, aeronautical information services, etc. In addition, data obtained from geostationary weather satellites, international images from NOAA's National Weather Service, Eumetsat, aeronautical charts for flight planning from Sky Vector Aeronautical Charts, Windy application were also used. The obtained results show very clearly the areas where icing occurred for the planes parked on the ground in 3 of the 7 airports and those during the flight, demonstrating that the study methods used allow surveys for longer periods of time, especially during late autumn, winter and late winter.
