Systems Description SR22T
fuel flow signal is sent to the Engine Airframe Unit, processed, and
transmitted to the Engine Indicating System for display.
The gage displays a green normal arc, which is dynamically updated
to display the range of normal values appropriate to engine power
settings.
•When manifold pressures is above 30.6 in.Hg, the green arc
covers a narrow range depicting the full rich fuel flow
appropriate for that power setting.
•For manifold pressures of 30.5 in.Hg and below, the normal arc
extends from full rich limit to 10 gallons per hour (indicating that
cruise leaning is permitted).
Target Fuel Flow is a cyan pointer plac ed on the fuel gage to i ndicate
best economy target fuel flow. This pointer is displayed when cruise
leaning is allowed (manifold pressure of 30.5 in.Hg or below), it will be
presented after the green arc expands when power is reduced. This
indicator provides guidance to aide in cruise leaning, it is calculated to
provide a fuel flow closely corresponding with the best economy fuel to
air ratio.
• Note •
Target Fu el Flow i s removed from ga ge whe n r esulti ng engi ne
power would be less than 55% (intended for cruise, not
descent leaning guidance).
Fuel Totalizer and Calculated Information
Fuel totalizer calculations are located in the lower right section of the
ENGINE page and are separate and independent of the fuel quantity
gage and float sensor system. The fuel totalizer monitors fuel flow and
calculates fuel-to-destination, fuel used, fuel remaining, time
remaining, fuel range, and nautical miles per gallon. Upon system
startup, the fuel totalizer initial fuel screen appears and prompts the
user to enter the total fuel on board at start. The option to enter the
number of gallons added since last fuel fill and the ability to set fuel to
“Full” or to “Tabs” buttons is also available.
Fuel System Annunciations
Fuel system health, caution, and warning messages are displayed in
color-coded text in the Crew Alerting System (CAS) window located to
the right of the Altimeter and Vertical Speed Indicator. In combination
with a CAS alert, the affected fuel parameter displayed on the
