WARNING
:
We recommend using the measuring method with only
one fuel flow sender for engines with a fuel flow back system
. The
indicated values are not only more precise than when using two senders, you
only have to buy and mount one sender.
5.3.7 Display of Fuel Flow
By pressing the >
FUNC/SET
< key briefly, the altitude display is temporarily replaced
by the fuel flow in either litres/hour or US-Gallon/hour. Pressing >
FUNC/SET
< again
will switch back to altitude. The fuel flow units can be changed in SET-Mode 25 from
litres/h to US-Gallon/h. For details see section 7.6.
The fuel flow indication is averaged. If the RPM of the engine is changed, it
can take a few seconds until the new fuel flow is indicated.
If the >FUNC/SET< key is not pressed a second time, for safety reasons the
display automatically reverts to altitude after a few seconds.
5.3.8 Calibration of Fuel Flow Meter
Because the fuel systems are different in every aircraft, we recommend calibration of
the fuel flow meter. This can be done in SET-Mode 3. The default value is a factor of
