However, without a background in IT, a pilot might easily fail to
realize that the screen could go black in the first place. After all,
steam gauges don't disappear in a puff of smoke, so why would anyone
intuitively assume that a glass cockpit would?


Most people know that the TV set turns off when the power goes out. You
would have to be incredibly stupid to not know that the panels will go
off in a power failure. Besides, the POH specifically points it out,
and the plane has a backup battery and the POH tells you how long the
screens will continue to operate on the backup battery.
