Can anyone give a technical justification for why the ATR seems to get into difficulties with icing at altitude, whereas other current types do not have a history of losses due to this
I believe that there were modifications to the de-iceing boots after the Roselawn accident. Do we know if this plane had the modifications?
ATR-42s have been operated non-stop in Canada since around 1990. Thats 20 years and no crashes.
About the only areas in Canada that generally can form Rime Ice is just along the coastlines. Profound difference between cold, snow vs -1c rime conditions.
