1.5.1.1 AIRCRAFT POWER
The G5 can operate using power from one or both inputs (AIRCRAFT POWER 1 and
AIRCRAFT POWER 2). The pins are internally connected using diodes to prevent current
from flowing between the two power inputs. AIRCRAFT POWER 2 is for connecting to
an alternate power source, such as on aircraft with two electrical buses.
