Gents:

 

This is a philosophical question as well as a = technical recommendation question.

 

A) would you consider a de-ice system for the = IV-P?

 

B) if so, which technology would you = use?

 

In general, I don’t believe in flying small = planes anywhere near icing conditions (been there done that – sinking = feeling when you are at full throttle and unable to maintain level flight = – then your prop heat throws off a chunk of ice that hits the windshield like a = brick…. Just to keep your heart rate and blood pressure way high off the = chart.)

 

And, having said the above, after you have done = everything possible to avoid icing conditions, and you still find yourself icing = up, it would be nice to be able to do something about it other than pray, which = I have done (“I promise to mend all my evil ways if you just help me out = of this one…”).

 

So, philosophically, would you recommend a de-ice = system?

 

If so, would you lean toward:

 

         =    Heated Leading Edge

         =    Electro Expulsive

         =    Glycol

         =    Rubber Boot

         =    Other?

 

As always, your thoughts/recommendations are = welcome.  Thanks in advance.

2/3rds done (I pray)

 

PS – I LIVE IN SEATTLE – THE WEATHER IS = ALWAYS SH1TTY, HERE.
