5.5 Fuel: EST TIME
This screen provides the following calculated Time data:
To EMPTY – This is the estimated time to empty based on the
fuel remaining and the current fuel flow.
To DEST – This is the time required to reach your destination
based on GPS data received.
At DEST – This is the reserve time after you reach your destina-
tion (Time to Empty – Time to Destination).
5.6 Fuel: EST AT DEST
This is a display of all the estimated reserves (after you reach your destination). The CGR-30P calculates the
Distance, Time and Fuel Qty in reserve early in the flight allowing the pilot to manage fuel and make critical deci-
sions as the flight progresses.
5.7 Fuel: EST USED
This screen provides the following calculated Fuel Used data:
Flight – This is the fuel used for the current flight. When the
flight timer starts, this field is reset to zero and fuel accumulates as
the flight progresses.
Since ADD – This is the fuel used since your last fill-up or if you
did not fill-up, since you added fuel.
Economy – This is your current economy in nautical miles per
gallon. It is calculated from the current fuel flow and GPS
ground speed. This can be very helpful in dealing with winds
aloft and leaning.
Leaning past 100 degrees rich of peak EGT reduces horsepower and therefore airspeed. It also reduces
fuel flow. The displayed Economy allows you to determine if continuing to lean produces a true fuel savings
and how much. Also, different altitudes can have different winds aloft. In this case the displayed Economy
allows you to determine if one altitude provides a fuel saving over another.
