Fuel Planning figures can be entered and displayed based upon one of
three possible configurations:
1) No fuel sensors connected - In this instance fuel flow is manually
entered and is used to calculate fuel on board. 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 calculated).
2) Fuel flow sensor installed, but no fuel on board sensor - Fuel on board
is manually entered. Fuel flow is automatically provided by the sensor. If
fuel flow is manually entered (to override the sensor), it will not affect the
FOB figure and is not retained the next time you view the page.
3) Fuel flow and fuel on board sensors installed - Fuel flow and fuel on
board are automatically provided by sensors. Fuel on board can NOT be
entered manually. Fuel flow can be entered manually, but will not affect
the FOB figure and is not retained the next time you view the page.
