r Basics
The fuel
flow
computer
tracks the
fuel
flowing to
the engine
and
computes
various
values
based on
this. At
installation
, then each
time you
refuel the
aircraft,
you must
inform the
EDM
about how
much
useable
fuel is
onboard.
This is
done via the REFUEL function. There are three ‘Quickset’ ways to do
this:
1. Main 74.0 GAL: MAIN tanks are filled (no other fuel onboard).
2. Main + Aux 94.0 GAL: MAIN +AUX tanks are filled.
