Pre-Flight Planning

  1. Field Assessment & Site Preparation

Before flying the drone, the operator must inspect the field to ensure a safe operation area.

  • Identify obstacles like trees, electric poles, wires, and buildings.
  • Check the ground surface for uneven areas or potential hazards.
  • Select a safe take-off and landing zone.
  • Ensure no people or animals are present in the spraying path.
    Good field preparation prevents accidents and ensures smooth drone operations.
  1. Weather Check & Wind Understanding

Weather plays a major role in drone stability and spraying accuracy.

  • Avoid flying in strong winds, rain, and thunderstorms.
  • Ideal wind speed is below 10–12 km/h for agricultural spraying.
  • Check humidity and temperature, as they affect battery performance.
  • Ensure visibility is clear for line-of-sight flying.
    Understanding weather patterns helps ensure safe and effective drone missions.
  1. Drone Inspection Checklist

A full inspection of the drone must be done before every flight:

  • Check airframe condition for cracks or loose parts.
  • Inspect motors and propellers for damage.
  • Verify GPS, compass, and IMU status.
  • Check landing gear and spray system.
  • Confirm firmware and software updates.
    This checklist ensures the drone is ready and reduces the risk of failure mid-flight.
  1. Battery Readiness & Propeller Check
  • Make sure batteries are fully charged and properly connected.
  • Check for swelling, damage, or overheating signs.
  • Ensure multiple spare batteries are ready for continuous operations.
  • Inspect propellers for cracks, bends, or loose screws.
  • Replace any damaged propeller immediately.
    Proper battery and propeller checks enhance flight safety and drone life.
  1. Mission Planning Using Flight Apps

Flight planning apps help create automated missions for precise spraying or mapping.

  • Set field boundaries and mark obstacles.
  • Choose altitude, speed, and spray width settings.
  • Define waypoints for autonomous flight.
  • Configure Return-to-Home settings.
  • Sync the mission plan with the drone before takeoff.
    Good mission planning ensures uniform spraying, accurate mapping, and efficient battery use.
