Hi guys,

I am also seeking clarification on the question regarding carburettor impact ice, as it is only briefly covered in Bob's notes with no mention of temperature range (I do have an older issue of the notes).

JeremyFr asked in his post
To which Bob replied
I managed to find an article about carb icing in the July-August 2001 edition of Flight Safety Australia.
They have stated thatThis statement agrees with Bob's comment regarding the humidity/moisture present, and the temperature of the aircraft surface, but not the temperature range of the ambient air.

The article goes on to stateSo first they state a range of 0^oC to -10^oC, then they narrow it down to "about" -4^oC. To me, the second statement combined with the first supports JeremyFr's answer selection of -4^oC and high humidity condition.

As an aside, the NZ CPL General Aircraft Technical Knowledge book states
I note that the posts I referred to are about a year old, has there been any more information added to the AGK notes since then? Have I just confused myself by looking deeper into it?

Thanks,

Craig
