Planning
COMPUTE FUEL STATISTICS
1. Select a fuel planning mode.
2. Define a leg or route.
•
If “Flight Plan” is set, select the flight plan and leg. Selecting the active
flight plan sets the starting waypoint at the aircraft’s current position.
•
If “Point to Point” is set, select From and To waypoints, or use the
aircraft’s current position as the From waypoint.
3. Specify the amount of fuel on board and average fuel flow rate.
4. Specify ground speed or elect to use sensor data.
5. Tap
Compute Data (GTN 650Xi Series only).
6. Tap Next or Prev to view statistics for other legs in the flight plan (if applicable).
If total fuel quantity or fuel flow values are supplied via sensor, GTN uses the
data from this app to calculate the Fuel Range Ring overlay on Map. Fuel range
rings indicate an estimate of remaining flight distance based on fuel onboard,
fuel consumptions rates, and current ground speed.
Map depicts two separate rings: one displaying range to reserve fuel, the other
displaying total endurance range. Both offer additional situational awareness
regarding fuel remaining and endurance.
