Garmin GNS 430 Pilot's Manual & Reference page 145

Trip Planning— allows the pilot to view desired track (DTK), distance (DIS),
estimated time en route (ETE), enroute safe altitude (ESA) and estimated time of arrival
(ETA) information for a direct-to, point-to-point between two specifi ed waypoints or for
any programmed fl ight 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 aircraft
will 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 tempera-
ture 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.
Crossfi ll— allows the pilot to transfer the active fl ight plan, any stored fl ight 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 GNS 430 is
powered on, until the message is deleted. Periodic messages will automatically reset to
the original timer value, once the message is displayed. Event-based messages do not use
a timer, but rather a specifi c date and time.
