Cooling and Heating on my IBIS RJ.03 aircraft

I haven't yet started to build this part of IBIS.

Carb icing

Carb Icing Chart - courtesy CAA

The adjacent carb icing chart clearly shows that carburettor icing is dependent on temperature, dewpoint and power setting. It also shows that the maximum dewpoint for the area I live (NW-Europe) can be as high as 22° C. What really was an eye-opener to me was the realization that with a relative humidity of less than 40%, serious carb icing is still possible when ambient temperature and dewpoint are within certain ranges.
Clearly, measures must be taken to prevent icing in the carburettor and this is where heating comes in.
