Drone Rules 2021 — India’s UAV Policy, Zones, PLI, Agriculture Use (UPSC Science & Tech)
Drone Rules 2021 — classification, airspace zones, Digital Sky, PLI scheme, agriculture drones, Namo Drone Didi — UPSC GS III notes.
In August 2021, India replaced a 160-page, permission-heavy drone regulation with a 35-page, trust-based framework. The Drone Rules 2021, notified by the Ministry of Civil Aviation on 25 August 2021, aim to make India a global drone hub by 2030. In 2024, the Namo Drone Didi scheme put drones in the hands of 15,000 women-led SHGs. Drones are now agricultural input, logistics vehicle, surveillance tool and battlefield weapon — all in one.
For UPSC GS III, drones sit under indigenisation of technology, defence, agriculture, infrastructure and disaster management — multiple sub-heads of the syllabus converge here.
Why New Rules Were Needed
Pre-2021 rules (Unmanned Aircraft Systems Rules 2020) required approvals for every drone flight, imposed multiple certifications and made commercial use almost impossible. India had a growing drone ecosystem but crippling regulation. The 2021 rules moved to self-certification, digital authorisation, and minimal human interface.
Salient Features of Drone Rules 2021
- Built on the premise of trust, self-certification and non-intrusive monitoring.
- Several approvals abolished: unique authorisation number, prototype certification, certificate of manufacturing, certificate of airworthiness, import clearance, student licence, remote pilot instructor authorisation.
- Digital Sky Platform — single-window online system for registrations, licences and flight authorisations.
- Interactive airspace map with green, yellow and red zones.
- No foreign ownership restriction in Indian drone companies.
- Imports regulated by DGFT, not MoCA.
- Drone coverage expanded from 300 kg to 500 kg — includes drone taxis.
- DGCA prescribes drone training; online pilot licences.
- Drones used by army, navy, air force are exempt.
Classification by Weight (including payload)
| Class | Weight |
|---|---|
| Nano | Less than 250 g |
| Micro | 250 g to 2 kg |
| Small | 2 kg to 25 kg |
| Medium | 25 kg to 150 kg |
| Large | More than 150 kg |
Airspace Zones
- Green zone — Up to 400 ft (120 m) AGL where no red or yellow zone is designated; and up to 200 ft (60 m) in a lateral band 8-12 km from airports. No permission required.
- Yellow zone — Requires permission from the ATC concerned.
- Red zone — Flight requires permission from the Central Government.
PLI Scheme for Drones
The Production Linked Incentive (PLI) scheme for drones and components was notified in September 2021 with an outlay of ₹120 crore. It offers manufacturers 20% of value addition over three years. Minimum value addition thresholds vary by year. The PLI covers:
- Airframes
- Propulsion systems
- Flight controllers
- Batteries and power systems
- Sensors (lidar, cameras, GPS modules)
- Simulator and safety equipment
Notified beneficiaries include IdeaForge, Garuda Aerospace, Asteria Aerospace and several MSME manufacturers.
Applications of Drones
Agriculture
- Spraying — Pesticides, fertilisers, herbicides.
- Seeding — Aerial seeding of fodder crops and reforestation.
- Yield estimation — NIR sensors track photosynthesis.
- Soil analysis — Moisture, nitrogen mapping.
- Crop insurance verification — PMFBY damage claims.
- Livestock monitoring.
Benefits over manual spraying: 20-40 hectares per day, 30% pesticide saving, 90% water saving with ultra-low-volume spraying, no direct contact with chemicals.
Defence and Security
- ISR (Intelligence, Surveillance, Reconnaissance) — Border and LoC surveillance.
- Armed drones — Swarm drones, loitering munitions.
- Operation Sindhu and Balakot-era reconnaissance examples.
- Border management — BSF drone fleets on western and northern borders.
Commerce and Logistics
- Last-mile delivery — Flipkart, Dunzo, Swiggy pilots.
- Medicine delivery — Medicine-from-the-sky in Telangana.
- Food delivery trials in select cities.
Disaster Management
- Post-disaster survey (cyclones, floods, earthquakes).
- Search and rescue.
- Damage assessment for relief disbursal.
Healthcare
- Vaccine delivery to remote areas (Meghalaya, Arunachal Pradesh).
- Organ transport (trial projects).
- Blood sample collection.
Environment and Forestry
- Forest-fire detection.
- Anti-poaching surveillance.
- Wildlife census.
- Illegal mining detection.
Meteorology
- Lower atmosphere profiling — cheaper than balloons and sondes.
- Cyclone tracking.
Construction and Mining
- Site survey and volumetric analysis.
- Stockpile measurement.
- Progress tracking for PM Gati Shakti projects.
Entertainment
- Cinematography, drone light shows.
- Republic Day 2024 drone show at Kartavya Path used 1,000 drones.
Namo Drone Didi Scheme (2023-24)
Announced in 2023, rolled out 2024:
- 15,000 women-led Self-Help Groups (SHGs) to be equipped with drones.
- Drones used for spraying fertilisers, pesticides, seed application.
- ₹8 lakh subsidy per drone kit (up to 80%).
- Training provided to one member per SHG.
- Total outlay: ₹1,261 crore over 2024-26.
