I know about the air pressure-based AOA indicators driving electronic displays or analog differential pressure gauges, and the vane-type gauges driving sensors for electronic displays, and the old Bacon Saver arrow on a stick. But does anyone know of any mechanical AOA indicators that drive a cockpit display with no electronics at all? I can certainly imagine a vane driving a push-pull cable to move a mechanical display, for example, but someone must have done something like this before. Perhaps using model aircraft push-pull cable and ends?
