Conic Plates
According to the EASA EAD, these new-fangled "conic" plates could be either factory fitted or retro-fitted to both the Thales and Goodrich AoA probes. Can anyone explain their purpose? To prevent damage to the existing vanes, perhaps? Or to prevent icing?
Presumably they are comparable to the installation on VC10s in the 1960s, but bigger? Any chance someone might have a photo, or be able to take one while going up the front steps?
Thanks in anticipation...
