    $\begingroup$ It's where you stow the garage door remote ;) $\endgroup$ – GdD Dec 7 '19 at 17:45

    $\begingroup$ @GdD Wow, didn't know that! I thought if you pull it it activates the ejection seat. $\endgroup$ – HeadhunterKev Dec 9 '19 at 14:20

That's where the analogue/backup compass is stowed. The compartment can be opened downward if you ever need to use the compass, as seen in this image:

    $\begingroup$ Why is it designed to be stowable? It doesn't seem to impede cockpit visibility when deployed, and surely the stowing mechanism adds at least a little bit of weight and cost. Is it just for aesthetic reasons? $\endgroup$ – David Dec 8 '19 at 19:31

    $\begingroup$ @David Just a guess, but I suspect that Airbus management was embarrassed to put such a low tech instrument into their most advanced cockpit. So they decided to hide it after pilots refused to fly without. $\endgroup$ – Peter Kämpf Dec 8 '19 at 21:02

    $\begingroup$ @PeterKämpf It likely would not have passed FAA certification without one, though. It's standard equipment required on any aircraft. $\endgroup$ – Tyzoid Dec 8 '19 at 21:09

    $\begingroup$ Being stow-able means less likelihood of accidental damage (which, as its probably on the MEL is quite significant), you can turn the light off unless its in its open position etc etc etc. $\endgroup$ – Moo Dec 9 '19 at 0:26

    $\begingroup$ I believe the Airbus terminology for this guy is standby compass, but the description as a backup/analogue compass is accurate. $\endgroup$ – verandaguy Dec 9 '19 at 15:10
