Start Up Fuel
During flight you may also inform the FS-450M of startup fuel
using the pilot program mode. See page 5 for the steps to take to
set the start up fuel if you did not set it during power up.
Indexing Rate
In the automatic mode the display will automatically index through
each parameter and pause for a period of time. The pause time can
be set from between 1 and 9 seconds. Set the rate to 0 to inhibit the
automatic indexing mode.
Fuel Flow Parameters
The pilot may set three parameters:
• K Factors—the fuel flow transducers calibration constants.
• Accumulate for extended trip—default is OFF: reset the fuel
used to 0 every time you inform the FS-450M that the aircraft
was refueled. With accumulate ON fuel used will not be reset
to 0 when you inform the FS-450M that the aircraft was
refueled.
• GPS Communications fuel data format.
K Factors
The K factor is shown on each fuel flow transducer as a four digit
number, which is the number of pulses generated per gallon of fuel
flow. Before installing the transducer, write down the K factors
here: Left_________ Right________. To enter the number,
move the decimal point three places to the left. For example if the
K factor on the fuel flow transducer is 29,123, enter 29.12 in the K
factor parameter.
The K factor can be changed in the pilot programming procedure.
When the K factor is changed during a trip, calculations of fuel
