may I throw in
another question..
we may need a dedicated pitot / air data system specialist to answer that after some soul searching..
am i correct??
heated probes are part of the anti-ice protection of any transport aircraft..
having said that, "anti-icing", like in "heated" are preventive anticipating systems..
(or "have been")
we all know the old probes, that had been heated to the max from take-off to touch down..same heat as in "very hot"..may not have been the most elegant way, they did look "burnt" after awhile, but as long as they worked one could be pretty sure that whatever nature would throw at them, those things kept free of ice..
now, with the newer probes, as I understand, those are controlled by thermostats.. for all kinds of good reasons maybe..
however, as we know, problems with newer type probes always surfaced in a highly dynamic environment, i.e. sudden temp & humidity changes..
could it be that by the philosophy of the newer designs, that their heating circuits by nature simply do not respond fast enough to sudden temp & humidity changes, i.e. perverting the "anti - ice" philosophy to the point that an original preventive system becomes a reactive system..??
not sure whether I worded my question correctly..
