I have a dual Dynon system with a TruTrak wing leveler as one of the back-up instruments. I am looking for a way to indicate that the power has failed to the TruTrak as it has nothing internal.
I could sense it and display on The Skyview but that makes no sense as I probably only need it if the Skyviews have failed! Likewise, I can't use a relay and a light as it is not failsafe and, again, I am only likely to be on standby if there has been some sort of major instrument or electrical failure.
I am thinking about some sort of magnetic dolls eye (a la 1960s) that is held in the ON position by power and goes OFF or barbers pole when power is removed. Anyone know where I can get something like this or have any other ideas? Maybe I am missing something very simple.......
