The ETA list shows the ETA's for the waypoints of the active route, along with distance, bearing and the arrival time. The columns of the ETA list can be reordered and resized, and this order is saved when the program is closed. The ETA list is updated when a new position fix is received.
To use the ETA list, you must first create a layout that contains an ETA List. Then you must activate a route by right clicking on a waypoint and selecting "Activate Route From This Waypoint".
