Very large areas can be covered with one flight plan, even if multiple flights are needed. WingtraPilot offers a feature that allows you to resume a flight plan after landing to swap the batteries. When Return-to-Home is triggered, either manually or by low battery, WingtraOne returns to land. In any case, WingtraOne needs to be re-powered. At this point, the part of the flight plan that was not flown yet can still be incorporated. You can also activate the geofence and other safety settings in these battery breaks, as well as move the home point to a more convenient location if needed.
To resume the flight plan simply go through the pre-flight checklist again and launch the flight. The resume point is shown on the map as displayed in the picture below by the encircled "R." The flight plan is always resumed from the beginning of the flight line that the previous mission was interrupted, in order to ensure full coverage of the area. The height next to the resume point (R) indicates the height at which WingtraOne will fly to resume the mission. If mission height is above transition height, WingtraOne will rise in the loiter circle directly after forward transition. If the mission height is below the transition altitude, WingtraOne flies up to the transition altitude at the resume point, which is also a loiter waypoint where it will descend to the height of the mission.
