This switch is normally used before the auto-
pilot is engaged, to synchronize the autopilot

attitude.
Fuel crossfeed window
This sub-panel is located between the pilot
seats and contains the fire wall shut-off valves
for both engines, and a fuel crossfeed selector.
The fire wall shut-off valves are mechanical
valves which will cut off fuel flow from the
respective tank to the engine. The fuel crossfeed
valve opens a connection between the left
and the right wing tank, should feeding fuel
from one tank to the other become necessary.
To crossfeed fuel from one tank to the other
engine, close the fire wall shut-off valve for the
inoperative engine, and open the crossfeed
valve.
