Because it fly at low altitude, please be able to maneuver to check obstacles around me before you start the mission.
Also, I want the altitude confirmed by maneuvering to be reflected in the altitude of the mission.
In the example of Clifden Castle, in order to check the altitude 20m of “Set3”, I want to check if there are obstacles more than 20m around.
I would like to set the increase / decrease value of altitude and make 2 pass flight.
With +30m, “Set1” will be executed as the second pass after “Set3” is over.
