SECTION 7
AIRCRAFT AND SYSTEMS

Both: The engine is fed by both fuel tanks

Left: Fuel is supplied by the left tank.

Right: Fuel is supplied by the right tank.

Off: Fuel supply to the engine is cut off.
Fuel will flow from one tank to the other when the selector
is in either the Off or the Both position. When parking the
aircraft on a slope, leave the selector on either the left or
right position.
The engine may be operated on the Both, Left or Right
positions. However, the Both position is required for
takeoff and landing.
Fuel quantity is determined with two sight glass gauges
located on either side of the cockpit at the wing root
(Figure 7-7).
vented fuel caps and tubes at the forward outboard edge.
These tubes protrude under the wing close to the forward
wing strut attachment and have check valves installed to
allow air to be drawn in for venting and prevent fuel from
draining out.
Prior to refueling the aircraft, connect the fueling
equipment's grounding wire to either of the wing tie
downs (Figure 7-8). This will ensure that there is no
electrical potential difference between the aircraft and the
fueling equipment and will minimize the risk of electrical
sparks when the aircraft is being refueled.
