Drones have moved from hobby tools to workhorses for farms, mapping, rescue and even deliveries. Recent airspace disruptions in parts of Europe also show why counter-drone readiness is vital for airports and cities.

Types 

• By weight: Nano (up to 250 g), Micro (250 g–2 kg), Small (2–25 kg), Medium (25–150 kg), Large (above 150 kg).
  
• By design: Multi-rotor (easy to hover), Fixed-wing (long range), Hybrid (mix of both).
  

Where drones help

• Agriculture: crop spraying and monitoring; women self-help groups are entering this service.
  
• Land records: village property mapping under SVAMITVA has sped up title cards.
  
• Rescue and logistics: hilly and flood-hit areas use drones to scout routes and drop essentials.
  
• Industry: type-certified Indian platforms and components are growing under incentives.
  

Security lessons (hints from recent disruptions)

• Airports and cities need layered defences—detection, tracking, jammer and microwave or laser options—yet tools that destroy drones can be risky in crowded zones.
  
• Clear operating rules, no-fly zones, real-time coordination and fast investigation protocols are as important as technology.
  

Key terms 

• Type certification: safety approval for a drone model.
  
• Counter-drone system: tools that detect, track, disable or take over a drone.
  
• No-fly zone: area where flying is restricted for security or safety.
  

Exam hook

UPSC Prelims question
Q. Consider the following statements about drones in India:

1. Classification by maximum weight includes nano, micro, small, medium and large categories.
   
2. Uses span agriculture, mapping, disaster response and last-mile logistics.
   
3. Counter-drone tools that destroy drones are always safe to use in cities.
   
4. Fixed-wing platforms generally offer longer range than multi-rotor designs.
   Which of the statements given above are correct?
   

One-line wrap: Clear rules, everyday use-cases and careful counter-drone planning can make drones a public good—without turning the sky into a risk.
