Fuel Pumps
The fuel system is equipped with a mechanical and an electrical fuel pump. The
mechanical pump provides for the normal fuel supply.
The electrical fuel pump is provided as an auxiliary and emergency pump, which does
not operate under normal circumstances. It is operated with the FUEL PUMP switch on
the row of switches on the instrument panel. It is checked during engine start, and is used
as a safety back-up during take-off and landing, as well as when switching fuel tanks.
It is also switched on for safety in the event of a decrease in fuel pressure.
Fuel Tank Selector
The fuel tank selector is situated on the center console. Its positions are LEFT (tank),
RIGHT (tank) and OFF. The OFF position is reached by turning the selector to the right
while pulling up the safety catch of the fuel tank selector. This is to ensure that an OFF
selection is not made unintentionally.
