Briefing
procedure/explain mission
abortion criteria
determine observer, protocol
Editing positions (coordinates) in QGroundControl
Enter coordinates waypoint/pattern by clicking ☰ > Edit position... (right hand side) or drag&drop
Set Altitude: 550 m
For a search pattern, click Pattern > Survey > Basic/Circular and edit values:
Trigger Distance (for a camera, not used)
Spacing: 1800 m (theoretically 2068 m w/o overlap)
You may want to Rotate Entry Point for a quicker start.
(optional) Sun position dependent flying to reduce image reflections
Cameras of the plane are to the left and right of the plane - thus the sun should be always infront or behind the drone to reduce reflections
Choose the angle of the pattern flight the same as the current sun azimuth
Check communication channels with bridge and recovery crew
Battery charged (16.8 V)
Tighten the screws in the wings
Check for visual defects
