MEASURING STICK TABLES
To determine the fuel quantity, the airplane must be laterally leveled
with roll angles between -1° to +1°and pitch angles between -2° to +2°.
After refueling the airplane, start at the external measuring stick, closer
to the wing tip. For airplanes without wing stub tank, between 1503
and 2131 liters (397 and 563 US gal), the external measuring stick
provides a correct fuel level indication. Above 2131 liters (563 US gal),
it is not possible to measure the fuel level through the measuring
sticks. If the external measuring stick provides a zero indication, use
the internal measuring stick to obtain the fuel level. It is also not
possible to measure the fuel level through the measuring sticks, if it is
below 448 liters (118 US gal).
For airplanes with wing stub tank, between 2163 and 2791 liters (571
and 737 US gal) the external measuring stick provides a correct fuel
level indication. Above 2791 liters (737 US gal), it is not possible to
measure the fuel level through the sticks. If the external measuring
stick provides a zero indication, use the internal measuring stick to
obtain the fuel level. Between 781 and 2168 liters (206 and
573 US gal) the internal measuring stick provides a correct fuel level
indication. If the internal measuring stick provides a zero indication,
use the wing stub stick to obtain the fuel level. It is also not possible to
measure the fuel level through the measuring sticks, if it is below
7 liters (2 US gal).
Enter the measuring stick tables with the value read on the stick to
obtain the fuel quantity (liters or US gal). To find the fuel mass in
kg (lb) multiply the volume in liters (US gal) by the actual fuel density
in kg/l (lb/US gal).
NOTE: - Do not add measuring sticks values.
- After the airplane refueling or after the fuel pumps are
turned OFF, it is necessary to wait 10 minutes before reading
the measuring sticks.
