Why isn't the carb heated all the time?
This question popped up yesterday but I forgot to ask my instructor, so here you go..
I just wondered why couldn't the carb heat either A) stay on constantly or B) the carb be modified so that there was always a flow of warm air to/through it, removing the need to 'remember' (not that I have an issue with remembering!) to switch it on when reducing power, during the FREDA check, etc.
Perhaps the answer to this will become obvious when I've done the work for the Aircraft Technical exam, but in the meantime could anyone explain this for me?
Thanks,
Rich
