2.8 FUEL COMPUTER NORMAL OPERATION MODES
Choose one of the desired fuel computer modes on the selector
switch:
'GPH' - This mode displays the fuel flow in Gallons Per Hour both
digitally and graphically. The digital section provides 0.1 gallon
resolution. The graphic section provides you with a quick reference of
the current fuel flow. This is very useful during power changes. An
exclusive feature of our fuel flow computer is its ability to 'damp out'
the wide variations in displayed fuel flow normally seen on other fuel
flow digital readouts. Our system will smooth these short-term flow
variations to give you a steady flow indication with NO sacrifice in
accuracy.
'FLT' - This mode displays the gallons of fuel used in FLighT since
system power up. It is digitally displayed in 0.1 gallon increments. The
graphic display is shut off as it has no relationship to this parameter.
'HRS' - This mode displays the calculated HouRS of fuel remaining
(sometimes referred to as endurance), as a function of the current
flow rate and current fuel total in the computers memory. It is digitally
displayed in 0.1 hour increments. This mode is ONLY meaningful, if
you have kept the computers memory updated with fuel information
and have always had the computer operational when fuel is being
burned. The graphic display is shut off as it has no relationship to this
parameter.
'TOT' - This mode displays the current fuel total remaining in gallons.
It is digitally displayed in 0.1 gallon increments. This mode is ONLY
meaningful, if you have kept the computers memory updated with fuel
information and have always had the computer operational when fuel
is being burned. The graphic display is shut off as it has no
relationship to this parameter.
