One of the latest outcomes in the field of aircraft technology is the drone. Drones are unmanned remote controlled vehicles that can be accompanied with other technologies like a video camera. As a result of it, it enables it to make videos of objects or scenarios which humans cannot reach. Because of their small size and ability to travel to great heights and long distances, drones have found far-fetched applications in several fields. Some of the uses of drones will include:
Search and rescue operations
Previously, these kinds of operations are conducted with the help of helicopters 
and airplanes. However, these vehicles are large and take time for their deployment. Moreover, they cannot reach all the places on earth. These missions require immediate actions, and there is no provision to waste time in this case. These machines can take off immediately when put into action. Additionally, the design of the drones consists of carbon fiber that can withstand adverse climatic condition like heavy rain or extreme temperature. These drones are also equipped with the latest data transfer technology in real time that will keep the main station updated with the most recent proceedings.
Inspection
Drones can be used for regular inspection of the functioning of machines at power grid stations, gas and oil plants. Most of these industries make use of high-risk machines and involvement of workers in person is generally not recommended. However, a drone can be used in this case to work autonomously resulting in a thorough yet rapid inspection. It is even possible to use the drones for inspection of wind turbines and high voltage lines since they can withstand magnetic field as well as high voltage.
Security and surveillance
Civil security has always been a matter of prime importance in today’s world especially when there is an increasing incidence of terrorist attacks. Previously helicopters are used for constant surveillance, but these vehicles are large and costly. Moreover, it requires special training courses for the protectors of the law. Drone is an efficient, cost-effective technology that does away with the need for such costly training programs. They can be equipped with associated technologies like the laser scanner which can make a comprehensive recording of the incident and immediately send the report to the main station.
Scientific and research purposes
For r
esearch purpose, it is very much important to have an overall view of the area under the project. Moreover, since the project concerns a particular region of the natural environment, it is also necessary to minimize the adverse effect of the research techniques on the eco-system. Usage of airplanes, helicopters or cars can significantly harm the natural environment. Opting for an eco-friendly alternative like a drone will always be on the cards. These gadgets make the least perturbations and aid in the research work in ways more than one. One can have the area photographed at various viewing angles and perspectives. Moreover, the drones can be equipped with robotics which can be used to do some o the experiments without the need of human interventions.
Aerial photography and videography
This aspect of the usage of a drone is wonderful news for all those who are in love with photography. Drones can be used to take breath-taking shots with awe-inspiring perspectives in a cost-effective manner. Nowadays, drones come with GPS-Position-Hold technology, which enables to take blur-free pictures and videos in windy conditions. These pictures can be rapidly transferred to the main computer thus preventing much space from getting used up. It is recommended to use single-lens reflex cameras to ensure best picture quality.
These are some of the possibilities where the drones can be used. The wide range of application each drone comes with makes it an obvious choice for alternatives to costly procedures. The results obtained till date has proved the drones to be much more effective than its predecessors.
