DMI har på foranledning af Havarikommissionen for Civil Luftfart og Jernbane (HCLJ) udarbejdet en rapport vedr. ”Carburettor Icing-probability” baseret på mere end 20 års radiosondedata.

 

Rapporten er benævnt ”Technical Report 04-25 Carburettor Icing-probability

 

Blandt rapportens konklusioner kan følgende to nævnes:

 

Citat

Generally the probability of carburettor icing is highest during the summer months,

Citat

The use of the carburettor icing chart requires knowledge of air temperature and dew point and

these data are only available (to the pilot) at ground levels. Forecasting air temperature and dew

point at various flight levels is not possible, as variations in three dimensions and time are very

complex.

 

Therefore, the pilot focus should not be on the temperature, the dew point, the relative humidity nor the carburettor icing chart.

 

The focus should primarily be on timely and routinely monitoring engine performance (RPM & Manifold Pressure) followed by proper and consequent

use of carburettor heating.
