Trip & Fuel Planning
The GPSMAP 175’s trip and fuel planning submenu lets you plan and
review distance, fuel, and ETE/ETA information between any two waypoints;
your present position and a stored waypoint; or any part of a stored route.
Sunrise and sunset information is also provided. Two planning modes are
available: point-to-point and route planning.
To use the point-to-point planning mode:
1. Highlight the ‘Trip & Fuel Planning’ option from the main menu page and
press T.
2. If the plan field is not set to ‘Point-To-Point’, press the O key and select
it from the options page.
3. Highlight the first waypoint field and press T. Press the left arrow key
to clear the field, and use the R keypad to enter the name of the starting
waypoint. You may leave the waypoint field blank to use your present
position, or press the O key to select the waypoint from the nearest list,
the waypoint list, or the map display. Press T to confirm the waypoint.
4. Move the field highlight to the second waypoint field and follow the steps
above to select the destination waypoint.
5. Enter a speed for your trip in the speed field, or press O to select your
current SOG for the speed value.
6. Enter an hourly fuel flow (if desired) in the fuel field, and press T.
7. Enter the date and time of your departure (the default date and time will
be the current date and time in UTC or local time, whichever you have
selected) and press T.
The bottom of the page will now display the desired track and distance
between the two points; the estimated time enroute and fuel required; the date
and time of your arrival; and the sunrise and sunset times at the destination
for the date of arrival.
