Which of the following statements is FALSE regarding flight planning

Safety and regulations6:17
Equipment and app check list4:33
Ensure full equipment readiness for drone surveys by following a comprehensive preflight checklist: maintenance, batteries, cables, takeoff pad, safety gear, and essential apps (DJI Go, Drone Deploy, Litchi, GIS Essentials).
Marking boundary points4:15
Choosing the best take off point2:41
Select a take off point with at least a 5 meter radius of clear, unobstructed land near the flight plan center to optimize battery life and maintain signal.
Adjusting flight parameters based on site conditions1:57
Adjust on-site drone surveys by changing take-off points, altitude, and overlap (not below 70%) to handle obstacles and conserve battery, ensuring the survey completes.
