Heliski, in short no.
It seems to lessen the frequency if not set all the way down in temperature.
One other thing is that the AFT system fails more often than the FWD, and turning it off for a while and then turning it back on resets it.
There seem to be a general complaint about it but not much being done to solve this problem.
As a thought, it may be due to the high relative humidity that we get in the Gulf of Mexico (freezing somewhere in the ducts?).
