CESSNA SECTION 2
MODEL 162 AIRPLANE AND SYSTEM DESCRIPTION
GARMIN G300
U.S.
FUEL SYSTEM
(Continued)
FUEL DRAIN VALVES
The fuel system is equipped with 6 drain valves (4 in the wings and 2 in
the lower cowl) to provide a means for the examination of fuel in the
system for contamination and grade. The system should be examined
before each flight and after each refueling, by using the sampler cup
provided to drain fuel from each wing tank sump, the lower cowl fuel
shutoff valve drain and the fuel strainer sump lower cowl drain. If any
evidence of fuel contamination is found, it must be eliminated in
accordance with the preflight inspection checklist and the discussion in
Section 8. If takeoff weight limitations for the next flight permit, the fuel
tanks should be filled after each flight to prevent condensation.
ELECTRICAL SYSTEM
The airplane is equipped with a 14-volt direct current (DC) electrical
system powered by an engine driven alternator. A 12-volt main storage
battery is located on the right forward side of the firewall. The alternator
and main battery are controlled by the MASTER switch found on the
switch/circuit breaker panel.
The alternator and main battery power is supplied to a relay panel
located on the left forward side of the firewall. Power for all electrical
circuits, except the secondary power circuit, is supplied from the relay
panel to the electrical bus located in the switch/circuit breaker panel.
The electrical bus is supplied with power anytime the MASTER switch
is turned on. The electrical bus provides power to the avionics bus
through the AVN MASTER switch. The avionics bus is supplied with
power anytime the MASTER switch and AVN MASTER switch are
turned on.
The electrical system is equipped with a secondary battery located
between the firewall and the instrument panel. This secondary battery
supplies power to the secondary power circuit for PANEL LIGHTS
dimming as well as stable power to the G300 avionics and displays
during engine start. This prevents undesired panel light dimming and
loss of G300 information resulting from voltage drop during the engine
start. The secondary battery is also controlled by the MASTER switch
found on the switch/circuit breaker panel. Power is supplied to
equipment on the secondary power circuit anytime the MASTER switch
is turned on.
