My CFI and I were stumped as to what the purpose of this metal piece is on the roof of a 182. I couldn't find anything from searching Cessna POHs/docs online... Any ideas? probe

Here is a close-up: probe_close_up

This appears to be an Outside Air Temperature probe.

    $\begingroup$ @JScarry - Do not put a Jack-in-the-box, styrofoam, antennae ball on it. 😁 $\endgroup$
