Ok, so I've been looking in detail into one of my favorite turboprops, and I've got a couple of questions about it's anti-icing systems.

So far, I've found that it uses:

1. Electric heating for the forward wing.

2. Bleed air for the main wing

3. Pneumatic boots for the intakes.

However, it doesn't seem to have any prop protection at all. Is this because the exhaust passes through the prop?

And an even bigger question, why is the entire empennage unprotected? Surely the vertical and horizontal stabs must collect ice too!

Thanks in advance for any answers!
