Tail icing

[safewing]

So what question are we asking?

Is it fiscally okay to mitigate our assessment of contamination on certain aerodynamic surfaces?

I can understand the frustrations here; there has been insufficient research carried out on the middle ground.

We know what happens at the extremes.
Contamination = danger
Clean= safe

But aircraft operate in conditions where ice accumulates over time.

Obviously the aircraft can tolerate some level of contamination.

But where is the cut off point?

I don't think there is an aviation authority out there that would be brave enough to make a call like that.

And I don't think it is for us to take up the baton in the interim.

So as frustrating as it might seem I think unless the aviation industry is prepared to put a vast amount of investment on the specifics of partial icing then we have to accept the regulations incomplete as they are for what they are.
