Unmanned Aerial Vehicle: Definition, Benefit, Type, and Goal

Do you know that drones, also known as unmanned aircraft systems (UAS), have practical applications other than weapons and espionage? No? Here are a few to get to know better about UAVs.

What is an Unmanned Aerial Vehicle?

Drones are commonly known as an unmanned aerial vehicle (UAV) is a plane that does not have a human pilot or passengers. UAVs, also known as “drones,” can be fully or partially autonomous, but are usually controlled remotely by a human pilot.

What is the goal of an Unmanned Aerial Vehicle?

UAVs are used for reconnaissance and tactical planning. This technology is now available for use in the field of emergency response to help crew members. UAVs are classified based on their altitude range, endurance, and weight, and they can be used for a variety of purposes, including military and commercial applications.

What is the benefit of an Unmanned Aerial Vehicle?

Below, plenty of reasons exist to support the use of drones.

Aerial Imaging of High Quality

Drones are ideal for taking high-quality aerial photographs and video, as well as collecting massive amounts of imaging data. These high-resolution images can be used to create 3D maps and interactive 3D models, both of which have numerous applications. 3D mapping of disaster areas, for example, can help rescue teams be better prepared before entering dangerous situations.


Because unmanned aerial vehicles use GPS (Global Positioning System), they can be precisely programmed and maneuvered to precise locations. This is particularly useful in a variety of situations. UAVs, for example, are used in precision agriculture for a variety of farming needs, such as spraying fertilizer and insecticide, identifying weed infestations, and monitoring crop health. UAV precision saves farmers both time and money.

Deployment is simple

Because of advancements in control technology, most drones can be deployed and operated with little to no experience. Drones are becoming more accessible to a wider range of operators, thanks to the relatively low cost of most models. UAVs can also move more freely than manned aircraft. They can fly lower and in more directions, allowing them to easily navigate previously inaccessible areas.


Another advantage of using drones is increased security. Unmanned aerial vehicle operators with the proper license can use unmanned aerial vehicles to provide security and surveillance to private companies, sporting events, public gatherings, and other venues. Drones can also collect valuable data during and after natural disasters, which can aid in security and recovery efforts.

Types of Unmanned Aerial Vehicle you must know

UAVs may be classified as any other aircraft, according to design configuration such as weight, maximum flight altitude, degree of operational autonomy, operational role, etc. However, in this article, we’re going to talk based on weight categories and degree of autonomy only. 

As retrieved from the print.id, Drones are classified into five weight categories: nano (up to 250 g), micro air vehicles (MAV) (250 g – 2 kg), miniature UAV or small (SUAV) (2-25 kg), medium (25-150 kg), and large (over 150 kg) (over 150 kg). 

While based on percepto.co, Drones could also be classified based on the degree of autonomy with which they fly. Uncrewed aircraft are classified by the ICAO as either remotely piloted or fully autonomous. [22] Some UAVs have varying degrees of autonomy. For example, consider a vehicle that is piloted remotely in most situations but has an autonomous return-to-base operation. Some aircraft types may fly manned or as unmanned aerial vehicles (UAVs), which may include manned aircraft converted into uncrewed or Optionally Piloted UAVs (OPVs).

The benefit of using an Unmanned Aerial Vehicle

  1. They are capable of saving lives. UAS can be used to survey the damage, locate stranded and injured victims, and assess ongoing threats in natural and man-made disasters without jeopardizing the safety of rescue teams and first-responders.
  2. They can provide assistance to law enforcement. UAS can be used to find missing children, provide tactical surveillance and suspect tracking, aid in accident investigations, and monitor large crowds.
  3. They can help with infrastructure maintenance and management. Consider how difficult it is to inspect the underside of a bridge or the top of a skyscraper, not to mention the costs and risks involved. Scaffolding, cranes, or harnesses are not required with UAS. Simply deploy the system to remotely assess the structure’s condition.
  4. They have the potential to improve agricultural management. Farmers can target areas that require attention by using a crop management system to observe, measure, and respond to variability in individual plants. Farmers can improve yield, conserve resources, and avoid waste by identifying these areas and providing care only where it is needed.
  5. They can provide media with access to inaccessible locations. A UAS can capture aerial photography for a news broadcast or a blockbuster film in an efficient, cost-effective, and safe manner.
