Abstract

In-flight aircraft icing is a meteorological phenomenon that affects safety and regularity of flights. Large-sized aircraft are equipped with effective deicing systems. In addition, they may be subject to the routine anti-icing treatment, if necessary. Small-sized aircraft and unmanned aerial vehicles (UAV) do not have deicing systems, while even a slight accumulation of ice on UAV body deprives it of its ability to continue flying due to the low power available. In this regard, real-time forecasting (nowcasting) of the icing risk is of great importance. The methods available for icing prediction, use pilot balloon data, which usually implies a forecasting periods of 12 or 24 hours. Such long-term forecasts are virtually useless for the operation of small aircraft and UAVs. An alternative approach is the use of remote sensing methods to obtain the real-time data on atmospheric conditions and a forecast of icing hazard. The initial data for the forecast in this case are the vertical profile of air temperature and the integral water content of the air column. The paper considers the characteristics of radiometric data and meteorological parameters of the atmosphere in relation to the recorded cases of aircraft icing according to the data of Pulkovo Airport weather service. The ranges of integral moisture content and air temperature corresponding to various atmospheric conditions during aircraft icing periods and in its absence are determined. The results obtained made it possible to formulate threshold criteria for icing hazard warning system using an automated radiometric technique. The differences of forecast criteria for coastal (St. Petersburg) and intracontinental (Tomsk) zones are revealed and shown.

AB  - In-flight aircraft icing is a meteorological phenomenon that affects
safety and regularity of flights. Large-sized aircraft are equipped
with effective deicing systems. In addition, they may be subject to
the routine anti-icing treatment, if necessary. Small-sized aircraft
and unmanned aerial vehicles (UAV) do not have deicing systems, while
even a slight accumulation of ice on UAV body deprives it of its
ability to continue flying due to the low power available. In this
regard, real-time forecasting (nowcasting) of the icing risk is of
great importance. The methods available for icing prediction, use
pilot balloon data, which usually implies a forecasting periods of 12
or 24 hours. Such long-term forecasts are virtually useless for the
operation of small aircraft and UAVs.  An alternative approach is the
use of remote sensing methods to obtain the real-time data on
atmospheric conditions and a forecast of icing hazard. The initial
data for the forecast in this case are the vertical profile of air
temperature and the integral water content of the air column.  The
paper considers the characteristics of radiometric data and
meteorological parameters of the atmosphere in relation to the
recorded cases of aircraft icing according to the data of Pulkovo
Airport weather service. The ranges of integral moisture content and
air temperature corresponding to various atmospheric conditions
during aircraft icing periods and in its absence are determined. The
results obtained made it possible to formulate threshold criteria for
icing hazard warning system using an automated radiometric technique.
The differences of forecast criteria for coastal (St. Petersburg) and
intracontinental (Tomsk) zones are revealed and shown.
