Fuel Planning
— You may manually enter fuel flow, ground speed (GS)
and fuel on board figures for planning purposes. Fuel planning figures can be
displayed not only for the currently active flight plan or direct-to, but also point-
to-point between two specified waypoints and for any programmed flight plan.
Fuel on board and fuel flow may be manually entered in the unit start-up
sequence and used to recalculate fuel on board as it is consumed. When fuel
flow or fuel on board is manually entered, the figures are retained the next time
you view the page (with fuel on board continuously recalculated).
NOTE:
The capability of using Sensor Data is available in software versions
2.00, 4.10, and later.
