Yoke, and Fuel crossfeed windows

Fuel crossfeed window

This sub-panel is located between the pilot seats and contains the

re wall shut-off valves for both engines, and a fuel crossfeed

selector. The re wall shut-off valves are mechanical valves which

will cut off fuel ow 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

re wall shut-off valve for the inoperative engine, and open the

crossfeed valve.
