Flying a lot of missions recently where there are cranes on site.
I always measure the crane height visually / with the drone by flying up to it and checking the height on the flight app. This determines the minimum safe altitude (MSA) and the mapping height would be set to 20FT above this.
But cranes can move, so should there be a sudden requirement to stop due to a possible collision - what is the quickest, simplest way to immediately STOP the drone in the air? The pause button? The Manual Control button takes two taps and cancels the mission. Is there a button on the Phantom 4 controller that would immediately pause the UAV? In Litchi moving the mode switch from P to S will stop the drone…
What other safety tips and tricks do you have?
