Garmin GPS 400 Pilot's Manual And Reference page 121

Trip Planning— allows the pilot to view desired track (DTK), distance (DIS), esti-
mated time en route (ETE), enroute safe altitude (ESA) and estimated time of
arrival (ETA) information for a direct-to, point-to-point between two specified way-
points or for any programmed flight plan.
Point-to-point waypoints, flight plans and/or ground speed (default is
current GPS-calculated ground speed) entered on the fuel planning page
will automatically transfer to the trip planning page, and vice versa.
Density Alt / TAS / Winds— indicates the theoretical altitude at which your air-
craft will perform depending upon several environmental conditions, including
indicated altitude (IND ALT), barometric pressure (BARO) and total air tempera-
ture (TAT; the temperature, including the heating effect of speed, read on a stan-
dard 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-Series GARMIN units (GNS
430/GNC 420/GPS 400) in a dual-unit installation.
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 will appear once the timer expires and will reappear
each time the GPS 400 is powered on, until the message is deleted. Periodic mes-
sages will automatically reset to the original timer value, once the message is dis-
played. Event-based messages do not use a timer, but rather a specific date and
time.

The "Change Fields?" option above is only
available on GPS 400 installations which
include a Shadin fuel computer. In these
installations, use the "Change Fields?" option
to review separate fuel information for left
and right engines.
