1.2 System Power Up
Initial power up displays color bars on the screen. After several
seconds, the color bars are replaced by the flight application.
During aircraft power up, the display may start faster than other
systems, such as gyros, resulting in a time delay between power-up
and the system receiving valid signals. During this time, the display
will present color bars for a short time followed by failure warnings on
the ADI and HSI sections. After valid signals are received, the display
will begin functioning normally.
