Drones, also known as Unmanned Aerial Vehicles (UAVs), have transformed various industries by offering efficient, cost-effective, and versatile aerial solutions. Whether it's capturing breathtaking aerial imagery or enhancing agricultural productivity, drones have become indispensable tools in both personal and professional settings.
As drone technology continues to evolve, understanding the different types of drones and their applications is essential.
Classification of Drones in India: DGCA Guidelines
In India, the Directorate General of Civil Aviation (DGCA) classifies drones based on their weight, which determines their regulatory requirements:
Nano Drones (≤ 250 grams): Ideal for beginners and hobbyists, these drones are exempt from registration and are perfect for indoor use and basic photography.
Micro Drones (250 grams – 2 kg): Suitable for recreational use and amateur photography. They require registration but have fewer operational restrictions.
Small Drones (2 kg – 25 kg): Commonly used in commercial applications like agriculture, surveying, and media production. Operators must obtain a Remote Pilot Certificate.
Medium Drones (25 kg – 150 kg): Used in industrial applications, including logistics and large-scale surveillance. These drones require special permissions and adherence to stringent safety norms.
Large Drones (> 150 kg): Primarily utilized in defense and heavy industrial sectors, large drones are subject to rigorous regulatory oversight.
Understanding this classification of drones in India is crucial for compliance and optimal utilization.
What Are the Four Types of Drones?
Drones can also be categorized based on their design and flight capabilities. The four main types are:
1. Multi-Rotor Drones
The most common category of drone, multi-rotor drones include quadcopters, hexacopters, and octocopters. They are:
Pros: Easy to control, capable of vertical takeoff and landing (VTOL), and suitable for aerial photography and surveillance.
Cons: Limited flight time and payload capacity.
These drones are widely used in photography, agriculture, and inspection services.

2. Single-Rotor Drones
Resembling helicopters, single-rotor drones have one large rotor and a smaller tail rotor. They offer:
Pros: Longer flight times and higher payload capacity compared to multi-rotor drones.
Cons: More complex mechanics and higher operational costs.
They are often used in industrial applications and for carrying heavier equipment.
3. Fixed-Wing Drones
These drones have a rigid wing structure, similar to airplanes. They are:
Pros: Capable of covering long distances and staying airborne for extended periods.
Cons: Require runways or catapults for takeoff and landing, and cannot hover.
Fixed-wing drones are ideal for mapping, surveillance, and agricultural monitoring.
4. Fixed-Wing Hybrid VTOL Drones
Combining the benefits of fixed-wing and rotor-based designs, these drones can:
Pros: Take off and land vertically like multi-rotor drones and fly long distances like fixed-wing drones.
Cons: More complex and expensive than other types.
They are increasingly used in delivery services and large-scale surveying.
Types of Drones in India: Applications and Use Cases
India's diverse landscape and growing industries have led to the adoption of various drone types:
- Agricultural Drones: Used for crop monitoring, spraying pesticides, and assessing field conditions.
- Surveillance Drones: Employed by law enforcement and security agencies for monitoring and reconnaissance.
- Delivery Drones: Companies are exploring drones for delivering packages, especially in remote areas.
- Media and Entertainment Drones: Utilized for capturing aerial shots in films, weddings, and events.
- Industrial Inspection Drones: Deployed for inspecting infrastructure like pipelines, power lines, and bridges.
Understanding the category of drone suitable for each application ensures efficiency and compliance with regulations.

Frequently Asked Questions
Which type of drone is best for beginners in India?
For beginners, nano drones or micro drones are ideal. They are lightweight, easier to fly, and often exempt from stringent DGCA regulations. These drones are perfect for learning the basics and exploring recreational flying.
What permissions do I need to fly a drone in India?
You need to register your drone on the Digital Sky Platform by DGCA if it weighs more than 250 grams. Additionally, you must obtain a Remote Pilot Certificate for small and medium drones used in commercial applications.
Can I fly my drone anywhere in India?
No, drone operations are restricted in certain zones, especially near airports, military zones, and international borders. You must check No Permission No Takeoff (NPNT) zones via DGCA-approved apps before flying.
What is the average price range of different types of drones in India?
- Nano drones: ₹3,000–₹10,000
- Micro drones: ₹10,000–₹50,000
- Small commercial drones: ₹50,000–₹5 lakhs
- Fixed-wing or hybrid drones: ₹5 lakhs and above
Prices vary based on features, payload capacity, and brand.
How do I choose the right drone based on my use case?
- Photography & Videography: Multi-rotor drones (quadcopters)
- Agriculture: Fixed-wing or hybrid drones for larger coverage
- Inspection/Surveying: Small to medium drones with high-resolution sensors
- Delivery or Defense: Fixed-wing hybrid VTOL drones.
Consider your budget, payload needs, range, and regulatory compliance before making a decision.
