Fuel PlannNg - Garmin GPS 400W Pilot's Manual & Reference

Density Alt / TAS / Winds— indicates the theo-
retical altitude at which your aircraft will perform
depending upon several environmental conditions,
including indicated altitude (IND ALT), barometric
setting (BARO) and total air temperature (TAT; the
temperature, including the heating effect of speed,
read on a standard outside temperature gauge).
This computes true airspeed (TAS), based upon the
factors above and the calibrated airspeed (CAS).
Also, this determines winds aloft—the wind direc-
tion and speed—and a head wind/tail wind com-
ponent, 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 400W-Series
Garmin units 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
400W-series unit 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 specific date and time.
Fuel Planning
To perform fuel planning operations:
1. Select "Fuel Plannng" from the flght plannng
page.
2. The current fuel plannng "mode" s dsplayed
at the top of the page: "POINT TO POINT" or
"FPL" (for a flght plan). To change the mode,
press MENU to dsplay an optons wndow for
the other mode, then press ENT to accept the
other mode.
The "Flight Plan?" option allows you to
select the numbered flight plan for fuel plan-
ning. The "Change Fields?" option allows
you to select fuel information for each field
3a. For pont-to-pont fuel plannng, turn the small
and large right knobs to enter the dentfier
of the "from" waypont. Once the waypont's
dentfier s entered, press ENT to accept the
waypont. The flashng cursor moves to the
"to" waypont. Agan, turn the small and
large right knobs to enter the dentfier of
the "to" waypont and press ENT to accept
the waypont.
