ATR engine anti-ice or de-ice
Hi!
I'm looking for answers only from ATR technicians or pilots. With the risk of being shot down and laughed at:
I heard rumours that the ATR engine anti-ice system actually consists of boots around the intake. I remember seeing it for my self and not believing it, and then I heard a friend mention it too. Is it really so? Could someone please shine some light on this topic? Having a de-ice system as opposed to anti ice system around the intake seems a silly solution to me.

There are no silly questions.
ATRs indeed have de-icing boot around engine intake.
No, it is not a silly solution.
Behind intake is an S-duct with bypass door, which acts as centrifugal separator and prevents larger particles, such as ice shards, from reaching the LP compressor - BTW it's centrifugal type, less prone to fod than axial ones.
