FLIGHT PLAN FUEL PLANNING
The FUEL PLAN Page provides the capability to calculate fuel con-
sumption information for Active or Stored Flight Plans, DIRECT TO
Legs or Random Legs without affecting any of the system’s naviga-
tion functions.
The Fuel Plan Number and Origin and Destination identifiers,
TO/FROM leg and groundspeed value on this page will be identical
to the TRIP PLAN Page. Changing GS or the current leg on the
FUEL PLAN Page also affects the TRIP PLAN Page. Pilot initiated
changes made to the FLOW field on the FUEL STATUS Page are
reflected on the FUEL PLAN Page.
1. PLAN Key - DEPRESS to display FUEL PLAN Page.
NOTE: Initially the FUEL
PLAN will display the Active
Flight Plan (if selected). The
initial leg displayed will be
DIRECT TO the current TO
waypoint from NAV page 1.
