The Flight Planning Page Options are listed in Table 8-2.
Option
Fuel Planning When equipped with fuel flow (FF) and/or fuel on board (FOB) sensors, this option displays
current fuel conditions along the active direct-to or flight plan. The pilot may also manually enter
fuel flow, ground speed (GS) and (in some instances) 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.
Trip Planning Allows the pilot to view desired track (DTK), distance (DIS), estimated time enroute (ETE), enroute
safe altitude (ESA), and estimated time of arrival (ETA) information for a direct-to, point-to-point
between two specified waypoints, or for any programmed flight plan.
Density Alt/TAS/Winds Indicates the theoretical altitude at which the aircraft can perform depending upon several
environmental conditions, including indicated altitude (IND ALT), barometric pressure (BARO),
and total air temperature (TAT; the temperature, including the heating effect of speed, read on
a standard outside temperature gauge). This menu option computes true airspeed (TAS), based
upon the factors above and the calibrated airspeed (CAS). Also, this menu option determines
winds aloft (the wind direction and speed) and a head wind/tail wind component, based upon
the calculated density altitude (DEN ALT), true airspeed, aircraft heading (HDG), and ground
speed.
Crossfill Allows the pilot to transfer the active flight plan, any stored flight plan, a user waypoint, or all
user waypoints between two 400/500-series Garmin units in a dual-unit installation. See Section
4.1, Flight Plan Catalog Options and information following in this section for details.
Scheduler Displays reminder messages (such as 'Change oil', 'Switch fuel tanks', 'Overhaul', etc.). One-
time, periodic, and event-based messages are allowed. One-time messages appear once the
timer expires and reappear each time the GPS 400 is powered on, until the message is deleted.
Periodic messages automatically reset to the original timer value, once the message is displayed.
Event-based messages do not use a timer, but rather a specific date and time.
NOTE: Point-to-point waypoints, flight plans, and/or ground speed (default is current GPS-calculated ground
speed) entered on the Fuel Planning Page automatically transfers to the Trip Planning Page, and vice versa.
