*The DJI drone can fly faster than 7 m/s, but this is the recommended limit for high data quality *Make the field length the long dimension    
*If Flights/Field is >1, there will be additional time needed to land, swap batteries, and start a new flight    
         
Available Lens Focal Lengths (mm)     *This calculator assumes that the nominal lens focal length is the actual focal length. There may be some manufacturing variability in the actual focal length which will affect the FOV calculations.
