I have found an Avionic component, I am am not shure what it is.
It was made by the ARTHUR Electronics Inc. in La Crescenta,Calif in 1985. On
the front it says "Flite-Check".
It is a small black box (approx. 3 x 3 x 2 inch).
The front panel consists of a small Diplay, four LED (Start, Takeoff,
Landing and Stop.), a volume knob, a mode and "ADV" button.
On the back is a 8 pin round plug receptable, the kind you find on home
stereo equipment.
I think it is some sort of a electronic checklist.
Any clue about that ? How do i connect it ?
