Realised a week or so ago that there is no vario needle in the panel. Just triangles, lines and dots.

But there's a mysterious liquid-filled instrument near the bottom of the panel that has numbers on a wobbly thing inside.
It's not on the minimum equipment list. Should probably be stored somewhere with a sextant and knotted rope or the vacuum tube NAV radio from an Illyushin IL-76.
