Route Planning - Garmin NavTalk Owner's Manual

6.11.2 Route Planning

The Route Plan Page also displays trip planning
information for each leg or the entire route. Available
information includes desired course, time to waypoint,
distance to waypoint, required fuel and sunrise/sunset
times at the waypoint location.
To use the trip planning features:
Fuel flow rates on your NavTalk are measured in
"units per hour". System setting changes for units of
measure (statute, nautical or metric) do not affect the
fuel flow measure. You should enter fuel flow rates
based upon available information for your vehicle
(operator' s manual, performance specifications, etc.) and
make note of the desired units of measure (gallons,
liters, etc.)
