What's this extra pitot tube thing sticking out of the cabin wall on the Piper Arrow?
The Arrow I am flying at the moment hasn’t got one, although it looks as if there used to be one.
However, I hope to be flying an Arrow which I know has this “thing sticking out of the cabin wall” (port side). No doubt I'll be told when the time comes, but would be grateful if somebody could enlighten me as to its purpose now. Anticipated thanks.
