A method for utilizing a drone for intermittent flights can include: receiving instructions of a flight mission with a flight route from an original location to a mission destination of the drone, wherein a plurality of stand-by locations are configured for the drone to land on along the flight route; obtaining data of the stand-by locations; scanning a first area between the original location of the drone and a first stand-by location to determine whether the first area is clear; controlling the drone to navigate over the first area along the flight route if the first area is clear; updating a drone position in real time; scanning a second area between an updated drone position and a second stand-by location to determine whether the second area is clear; and controlling the drone to land on the first stand-by location if the second area is not clear.
