9 - AUX PAGES155190-00356-00 Rev GFlight PlanningDensity Alt / TAS / Winds— indicates the theo-retical altitude at which your aircraft will performdepending upon several environmental conditions,including indicated altitude (IND ALT), barometricsetting (BARO) and total air temperature (TAT; thetemperature, including the heating effect of speed,read on a standard outside temperature gauge).This computes true airspeed (TAS), based upon thefactors 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 activeflight plan, including VNAV parameters any storedflight plan, a user waypoint or all user waypointsbetween two 400W-Series Garmin units in a dual-unit installation.Scheduler— displays reminder messages (suchas “Change oil”, “Switch fuel tanks”, “Overhaul”,etc.). One-time, periodic, and event-based messagesare allowed. One-time messages will appear oncethe timer expires and will reappear each time the400W-series unit is powered on, until the messageis deleted. Periodic messages will automaticallyreset to the original timer value, once the messageis displayed. Event-based messages do not use atimer, but rather a specific date and time.Fuel PlanningTo perform fuel planning operations:1. Select “Fuel Planning” from the flight planningpage.2. The current fuel planning “mode” is displayedat the top of the page: “POINT TO POINT” or“FPL” (for a flight plan). To change the mode,press MENU to display an options window forthe other mode, then press ENT to accept theother mode.The “Flight Plan?” option allows you toselect the numbered flight plan for fuel plan-ning. The “Change Fields?” option allowsyou to select fuel information for each fieldas desired.3a. For point-to-point fuel planning, turn the smalland large right knobs to enter the identifierof the “from” waypoint. Once the waypoint’sidentifier is entered, press ENT to accept thewaypoint. The flashing cursor moves to the“to” waypoint. Again, turn the small andlarge right knobs to enter the identifier ofthe “to” waypoint and press ENT to acceptthe waypoint.
