Against the arguments "I have moved it by hand easily so it must work below 60kt", "It's not rocket science", "pressure affects both of its sides" and "find an opportunity to handle one" I'm totally powerless. Quite amused, too. Still, I maintain that indignant request for AoA vane to work flawlessly far outside the flight envelope is so unrealistic as to be ludicrous. I can take some comfort form making a big, fat assumption that it stems from ignorance and not agenda.
I'm still baffled.... why 'blame' the AoA vane?
The often-quoted recorded 60kts IAS was a result of the UAS (blocked pitots), it was NOT the real IAS of the aircraft at the time in question.
A lot of posts here do not seem to have made that easy conclusion....
