Abstract
The results of using the MTP-5PE meteorological temperature profiler for determining the spatial zones of potential aircraft icing in Tomsk airport on March 17, 2013, are presented. To determine the spatial zones the RAP-algorithm, the Godske method, and the AMIS-RF data to retrieve humidity profile were used. It is shown that the RAP-algorithm and the Godske method gave similar results on location of spatial zones of potential aircraft icing. However, the results obtained from the RAP-algorithm are closer to the actual icing reports received from the aircraft crews.
