Trip Planning
The GTN 6XX allows the pilot 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 item also displays the
sunrise/sunset times for your destination waypoint (for the selected departure
date). All times are based on the time set in System-Setup. For trip planning
inputs: departure time and date are manually entered, while ground speed can
be provided by sensor data, if selected.
The trip statistics are calculated based on the selected starting and ending
waypoints and the trip planning inputs.
In Flight Plan mode with a stored flight plan selected, and the entire flight
plan (CUM) selected, the waypoints are the starting and ending waypoints of the
selected flight plan.
In Flight Plan mode with a stored flight plan selected, and a specific leg
selected, the waypoints are the endpoints of the selected leg.
In Point-To-Point mode these are manually selected waypoints (if there is an
active flight plan, these default to the endpoints of the active leg).
Some of the calculated trip statistics are dashed when the selected leg of the
active flight plan has already been flown.
• Desired Track (DTK) - DTK is shown as nnn° and is the desired track
between the selected waypoints. It is dashed unless only a single leg is
selected.
• Distance (DIS) - The distance is shown in tenths of units up to 99.9, and
in whole units up to 9999.
• Estimated time en route (ETE) - ETE is shown as hours:minutes until less
than an hour, then it is shown as minutes:seconds.
• Estimated time of arrival (ETA) - ETA is shown as hours:minutes and is
the local time at the destination.
- If in Point-To-Point mode then the ETA is the ETE added to the
departure time.
