SYS (SYSTEM) TAB
The “SYS” (System) tab provides access to various system status
pages, a means to enter initial fuel (if configured with a
recognized fuel flow system) and a means to access IFD data
logs, update IFD software and update IFD databases.
FUEL MANAGEMENT
The “Fuel Mgmt” LSK will be displayed if the IFD has been
configured to interface with an aircraft fuel flow system. When
the LSK is pressed, the IFD will display the Fuel Management
Page.
The fuel management page shows data being reported by the
fuel flow system, as follows.
Flow – the current fuel flow rate
Used – the amount of fuel that has been used during this
flight
Rmng – the total usable fuel remaining on board the
aircraft
Time – the aircraft endurance based on the total usable
fuel remaining and current total fuel flow
Econ – the fuel economy based on total fuel flow and
groundspeed
The fuel management page will show either one or two fuel
“Flow” and “Used” fields based on whether the IFD is configured
for a single-engine or a multi-engine aircraft.
