Garmin GPS 500 Pilot's Manual & Reference page 123

• Fuel Flow Sensor Installed, But No Fuel On Board Sensor—Fuel on board is manually entered. Fuel flow is
automatically provided by sensor. If fuel flow is manually entered (to override the sensor), it does not affect the
FOB figure and is not retained the next time you view the page.
• Fuel Flow and Fuel On Board Sensors Installed—Fuel flow and fuel on board are automatically provided by
sensors. Fuel on board can NOT be entered manually. Fuel Flow can be entered manually, but does not affect the
FOB figure and is not retained the next time you view the page.
Trip Planning— allows you to view desired track (DTK), distance (DIS), estimated time en route
(ETE), en-route 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. This option also
displays the sunrise/sunset times for your destination waypoint (for the selected departure date).

NOTE: Point-to-point waypoints, flight plans and/or ground speeds (default is current
GPS-calculated ground speed) entered on the Fuel Planning page automatically transfer
to the Trip Planning page, and vice versa.
Density Alt / TAS / Winds— indicates the theoretical altitude at which your aircraft performs
depending upon several variables, 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.
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 500 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.
Crossfill— allows the pilot to transfer the active flight plan, any stored flight plan, a user waypoint or
all user waypoints between two 500-Series (or 400-Series) Garmin units in a dual-unit installation.

Flight Planning
The Trip Planning page calculates desired track,
distance, estimated time en route, en-route safe
altitude and estimated time of arrival for a specified
direct-to, point-to-point or flight plan.
Select the "Density Alt / TAS / Winds" option to
calculate density altitude, true airspeed and winds
aloft.
