Operating drone thermography in India requires compliance with DGCA’s Drone Rules 2021 and UAS Rules 2021 — covering drone registration on the Digital Sky Platform, Remote Pilot Certificate (RPC) for commercial operations, airspace zone classification, and specific permissions for controlled areas. Non-compliance penalties include fines up to ₹1 lakh and grounding of equipment under the Aircraft Act 1934.
A Delhi-based inspection company recently faced ₹75,000 in DGCA penalties and temporary suspension of operations after conducting commercial thermography surveys without valid Remote Pilot Certificates for two operators and missing drone registration for one aircraft. The financial penalty was secondary; the 45-day operational suspension cost ₹8.5 lakh in lost inspection contracts. Regulatory compliance is not optional for commercial drone operators.
India’s drone regulatory framework is evolving rapidly. The Drone Rules 2021 liberalised many requirements from the 2018 Civil Aviation Requirements, but introduced new mandatory digital systems (Digital Sky Platform, DroneAcknowledgement for flight clearances). The Production Linked Incentive (PLI) scheme for drones has boosted domestic manufacturing, and India’s National Counter Unmanned Aircraft System (NCUAS) policy adds security layers around critical infrastructure relevant to industrial thermography operators.
Key Takeaways
- Drone thermography operations involve using drones equipped with thermal imaging cameras to capture and analyze data for various applications such as building inspections, agriculture, and search and rescue missions.
- The Federal Aviation Administration (FAA) has specific regulations for drone operations, including registration requirements, airspace restrictions, and pilot certification.
- Drone operators must consider legal considerations for privacy and data protection, including obtaining consent for data collection and ensuring the security of the data collected.
- Insurance and liability considerations are important for drone operators to protect against potential accidents, property damage, and data breaches.
- Environmental and safety regulations for drone operations include compliance with environmental protection laws and ensuring safe operation to prevent accidents and injuries. Additionally, intellectual property considerations for drone thermography data involve protecting the ownership and use of the data collected. State and local regulations for drone operations may vary and must be considered when planning drone thermography operations.

The DGCA Framework for Commercial Drone Operations in India
India’s drone regulatory framework is governed by the Unmanned Aircraft System (UAS) Rules 2021, issued by the Directorate General of Civil Aviation. These rules came into force in August 2021 and replaced the earlier draft framework. All commercial drone operators in India — including those conducting drone thermography for solar farms and transmission line inspection — must comply with this framework. Operating a drone commercially without the required approvals is an offence under the Aircraft Act 1934 (as amended) and carries penalties including equipment seizure.
Key Requirements Under UAS Rules 2021
| Requirement | Detail | Applies To |
| Drone Registration | All drones above 250g must be registered on the Digital Sky Platform at digitalskyplatform.gov.in | All commercial operators |
| Remote Pilot Licence (RPL) | Required for Medium and Large category drones above 2kg MTOW. Issued after ground training, simulator, and flight test | Operators of inspection-grade drones |
| DGCA Type Certification | The drone model must be type-certified by DGCA. Check the DGCA approved drone list before purchasing or commissioning | Operators |
| Drone Operator Certificate | Required for commercial operations. Issued to the operating entity company, not just the individual pilot | Companies |
| NPNT — No Permission No Takeoff | Drones must receive real-time digital clearance from the Digital Sky Platform before each flight | All drones |
| NOTAM Filing | For flights near airports and controlled airspace, a NOTAM must be filed with AAI minimum 48 hours before flight | Flights near power infrastructure in controlled zones |
Drone Inspection Near Power Infrastructure — Specific Requirements
- NOTAM requirement: If the transmission corridor or substation is within 5km of a licensed aerodrome, a NOTAM must be filed. Outside 5km, a NOTAM is good practice but may not be strictly required depending on airspace classification.
- Asset owner permission: Transmission utilities — PGCIL, state transcos, DISCOMs — require written permission before a drone is flown over their infrastructure. Elion obtains this permission as part of project mobilisation.
- Safety clearance from conductors: Elion’s operating procedure requires minimum 30 metres horizontal clearance from any live conductor above 33kV, based on IEC 60900 safe approach distances.
- Load dispatch co-ordination: Load dispatch must be informed of inspection activity so they do not make switching operations during the inspection window.
No-Fly Zone Classification in India
- Red Zone: Flights prohibited. Requires special permission from Ministry of Civil Aviation. Applies within 2km of airports, international borders, certain government buildings.
- Yellow Zone: Controlled airspace. Flights require real-time digital clearance via NPNT on the Digital Sky Platform. Most urban areas fall in Yellow Zones.
- Green Zone: Uncontrolled airspace. Flights permitted without prior approval for registered drones below 400 feet AGL. Most rural transmission corridors and solar farms fall in Green Zones.
Elion’s Compliance Checklist for Every Mission
- Verify drone is registered on Digital Sky Platform and is DGCA type-certified
- Verify pilot holds valid Remote Pilot Licence (RPL) for the drone category
- Check flight area airspace classification on Digital Sky Platform
- File NOTAM with AAI if required by airspace classification or aerodrome proximity
- Obtain written permission from asset owner — power utility, plant operator, or property owner
- Brief local security and operations team at the inspection site before flight
- Conduct pre-flight safety check per Elion standard operating procedure
- Log all flight data on Digital Sky Platform per NPNT requirements

FAQs
Does Elion have the required DGCA certifications?
Yes. Elion’s drone operations follow all UAS Rules 2021 requirements including drone registration on the Digital Sky Platform, valid Remote Pilot Licences for our operators, and Drone Operator Certificate for the company. We provide certification documentation on request as part of project mobilisation.
Can a drone inspect a live 400kV transmission line?
Yes, subject to the compliance framework described above. The drone does not touch or approach the conductor — it maintains a safe standoff distance of 30 metres minimum from live conductors above 33kV. PGCIL and several state transcos have used drone thermography for transmission line inspection across India. The technology is proven and the regulatory framework supports it.
What happens if inspection is needed inside a restricted zone?
For restricted or controlled airspace, Elion applies for a Unique Authorization Number from the Digital Sky Platform in advance of the planned inspection date. For Red Zone areas near airports or international borders, we apply for special permission through the Ministry of Civil Aviation. We have managed these approvals for clients with assets in sensitive locations.
