Anti-ice operation

Not true. EAI must always be turned on for takeoff if icing conditions exist or are anticipated. There is no performance penalty for using EAI during a takeoff.

Re-read my post. I didn't say EAI wasn't required, I just said icing of the cowl was less likely at high thrust settings.

What types have you been flying, Robin? You have some strong opinions on the matter. Coming from flying turboprops to turbojets, I had to change my views a bit.

I personally fly gliders and Cessnas. My opinion comes from lots of research on the matter (studying crash reports, aircraft ops manuals, incidents involving specific types, and research into why those types are more prone vs. other types). I'm too aware of how deadly icing can be if not taken seriously, and what happens when the anti- or de-ice systems are mis-handled or fail. I find the subject of icing quite interesting, not only in terms of aviation, but in terms of structures, too (think power grid where pylons collapse under the weight if ice, or ships that are capsized due to ice). I keep wondering of there is a (better) method for keeping these structures ice-free, that doesn't involve brute force heating.

Best regards,

Robin.
