A steel cable connects the operating lever in the cockpit to the dump valve of the
(optional) fin tank and a further steel cable to the torque tube actuating the wing
tanks - see page 7.9.3.
On rigging the main wing panels, the torque tube in the fuselage is automatically
hooked up to the torsional drive of the dump valve plugs.
The torque tube is rotated to the "CLOSED" position by spring force - see page
7.9.2.
The operating lever locks in its respective final positions.
