Flying large areas

Very large areas can be covered with one flight plan, even if multiple flights are involved. WingtraPilot's resume feature allows you to continue a flight plan after landing to swap the batteries. When return-to-home is triggered—either manually or due to 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 can still be incorporated. During these battery breaks, you can also activate the geofence and other safety settings, 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." In order to ensure full coverage of the area, the flight plan always resumes from the beginning of the flight line where the previous mission was interrupted.  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.

How is the flight height affected by a change on the height of the take-off location before resuming the flight?

If terrain following is enabled the flight height will not change. The height is not relative to the take-off location but is always relative to the terrain.

If terrain following is disabled, the flight height is relative to the take-off location. In case the take-off location has changed, the absolute flight height will change also.
