DIRECT READING FUEL QUANTITY GAUGES
Under-Wing Magnetic Gauges
The airplane is equipped with two under-wing magnetic gauges, one
installed on each wing, providing a method for checking the fuel quantity up
to approximately 75 gallons (500 lb.) during the preight inspection of the
aircraft. The under-wing magnetic gauges are installed on the inboard portion
of the wings on the lower surfaces, and operate with a oat and magnet
mechanism to provide a direct indication of fuel quantity for use during
preight inspection.
Under-Wing Magnetic Gauge Instructions:
1. Push and turn the gauge stick 1/4 turn using a at-head screwdriver or
similar tool to release the stick from the housing.
2. Once the stick is accessible, pull briskly downward on the stick to
disconnect the magnetic stick from the oat inside the tank. Once the stick
is disconnected, it should feel light and easy to slide up or down.
3. Slowly lift the magnetic stick until it snaps upwards and reattaches to the
oat.
4. Read the fuel level by comparing the markings on the stick with the lower-
most at surface of the Magnetic Gauge housing.
Fuel Pipette
To measure fuel levels greater than 75 gallons (500 lb.), a qualied calibrated
fuel pipette inserted through the outboard ller port is one means of providing
accurate indication of the fuel onboard.
WING TANK LOW FUEL WARNING SYSTEM
The wing tank low fuel warning system consists of two optical sensors (one
located in each wing tank) which provide visual and aural annunciation
through the G1000. The warning system will activate when the fuel level in
either wing tank falls below approximately 100 pounds.
Visual annunciation is shown as follows:
FUEL LOW L – Indicates the fuel level in the left wing tank is below
approximately 100 pounds.
FUEL LOW R – Indicates the fuel level in the right wing tank is below
approximately 100 pounds.
FUEL LOW L-R – Indicates the fuel level in both wing tanks is below
approximately 200 pounds.
NOTE: Due to wing dihedral, the under-wing magnetic gauges are limited
to indicating a maximum of 75 gallons.
CAUTION: To obtain accurate measurements from a direct reading fuel
quantity gauge, the airplane must be parked on a level surface.
