The problem comes when the warning
device fails because the battery is flat or the electricity
can't bridge the air gap.

I test the circuit before each flight.

My spoiler warning curcuit rigged between the landing gear and spoilers on my
Jantar. The switch for the landing gear only opens if the landing gear is down
and the button on the handle is fully up, indicating a positive lock on the
landing gears. The switch on the spoilers only opens when the spoilers are in
the fully locked position.

To test, I depress the button on the landing gear handle and pop the spoilers a
little. This activates the gear warning by closing both switches.

Just in case one of the switches fails during flight, causing the alarm to go
off, I can deactive the system to avoid a beep-beep-beep on a long flight. I
have a toggle switch mounted high on the panel to power the circuit. Right
next to the switch is a large red LED. If I chose to deactive the gear warning
system, the red LED goes on.
