CESSNA SECTION 3
MODEL 208B 867 SHP EMERGENCY PROCEDURES
GARMIN G1000
FUEL SYSTEM MALFUNCTION
INADVERTENT FUEL FLOW INTERRUPTION
(Continued)
The fuel selector off warning system notifies the pilot if both FUEL
TANK SELECTORS are in the OFF position before engine start, if
either FUEL TANK SELECTOR is OFF during engine start, or if one
FUEL TANK SELECTOR is OFF and the fuel level in the tank being
used drops below approximately 25 gallons. The warning system
includes a red FUEL SELECT OFF annunciator and two aural warning
horns. If the FUEL SEL WARN circuit breaker has opened or the
START CONT circuit breaker has been opened or pulled (possibly for
ground maintenance), the red FUEL SELECT OFF annunciator will
come on even with both FUEL TANK SELECTORS in the ON position.
This annunciation serves as a warning to the pilot that the fuel selector
off warning system has been deactivated. Refer to Section 7, Airplane
and System Descriptions, Fuel Systems, for more information on the
fuel selector off warning system.
