A Guide to How Drones Are Used for Inspections
Drones are becoming an essential tool in modern inspection processes across various industries. By using drones, inspectors can collect visual data on the condition of assets without putting themselves in dangerous situations. This not only enhances safety but also improves efficiency and reduces costs.
Inspection drones are transforming traditional manual methods, enabling faster data collection while eliminating the need for risky physical inspections. For example, inspecting a cell tower manually could involve climbing several stories, whereas a drone can easily access the structure from above, capturing detailed images and videos without any risk.
In industrial settings, such as boiler or pressure vessel inspections, drones offer a safer alternative to scaffolding or rope access. Instead of risking injury, inspectors can use drones to gather critical information, which can then be reviewed later for analysis and decision-making.
With advancements in technology, drones are now equipped with sensors like LiDAR, thermal cameras, and multispectral imaging, allowing them to perform more than just visual inspections. These tools help detect issues that might not be visible to the naked eye, making inspections more comprehensive and accurate.

This guide explores the best inspection drones for different applications, the goals of aerial data collection, and the benefits of using drones in inspections. We'll also look at how various industries are leveraging this technology and the types of jobs available in the drone inspection field.
Whether you're looking to start a drone business or explore career opportunities, understanding the role of drones in inspections is crucial. From agriculture to mining, the applications are vast and continue to expand as technology evolves.
The Best Inspection Drones
Selecting the right inspection drone depends on the specific needs of the job. There are numerous options available, each designed for different environments and tasks. For large-scale land surveys, fixed-wing drones with long flight times are ideal. In urban or confined spaces, multi-rotor or quadcopter drones offer greater maneuverability. For tight, hazardous areas, cage drones like the Elios 3 are perfect, featuring advanced sensors and robust construction to withstand challenging conditions.
Each type of drone has its strengths, and choosing the right one ensures that inspections are both effective and safe. Whether it's for internal inspections in silos or external assessments of power lines, the right drone can make all the difference.
What Is a Visual Inspection and Why Is It Important?
A visual inspection involves a thorough examination of an asset using the naked eye. In many cases, drones replace the inspector’s eyes, collecting visual data that can be analyzed later. This method is particularly useful for identifying wear, damage, or potential hazards that may require maintenance.
For instance, inspecting a cell phone tower manually requires climbing to great heights, which can be time-consuming and risky. Drones eliminate these risks by providing a clear view of the structure, allowing inspectors to identify issues without physical exposure.
Visual inspections are crucial for maintaining the integrity of assets. They help prevent costly repairs and ensure the safety of personnel and the public. In industries like oil and gas or power generation, even small issues can lead to major problems if left unchecked.
Not All Drone Inspections Are Visual
While most drone inspections are visual, they can also be equipped with specialized sensors for other types of inspections. Thermal cameras, LiDAR, and multispectral sensors allow drones to detect heat leaks, measure distances, and analyze crop health, among other things.
For example, in agriculture, drones with multispectral sensors can assess crop health by analyzing different wavelengths of light. In HVAC inspections, thermal cameras can detect energy inefficiencies, helping to reduce costs and improve performance.
Some drones, like the Elios 3, can carry multiple payloads, including radiation detectors, LiDAR scanners, and ultrasonic thickness sensors. This versatility makes them ideal for a wide range of inspection tasks, from industrial facilities to underground mines.
Where Inspections Fit in the Maintenance Process
Inspections are the first step in the maintenance process. After identifying potential issues, repairs are made as needed. Drones play a vital role in this process by reducing the need for dangerous manual inspections, saving time, and lowering costs.
For example, instead of building scaffolding to inspect a boiler, a drone can quickly gather the necessary data. This approach not only improves safety but also minimizes downtime, allowing businesses to operate more efficiently.
While drones are valuable tools, they are not a replacement for human judgment. In some cases, manual inspections are still required, especially when complex decisions need to be made. However, drones provide a powerful supplement to traditional methods, enhancing overall inspection capabilities.
The Benefits of Drone Inspections
Drones offer numerous benefits, including improved safety, cost savings, and increased efficiency. By eliminating the need for manual inspections in dangerous environments, drones protect workers and reduce liability risks.
One of the key advantages of drone inspections is cost reduction. Building scaffolding for manual inspections can be expensive, and the time required for setup and removal adds to the overall cost. Drones eliminate these expenses, allowing companies to save up to 80-90% on inspection-related costs.
Additionally, drones reduce downtime. When an asset needs to be shut down for inspection, every second of delay can result in lost revenue. Using drones allows for quicker inspections, minimizing disruption and maximizing productivity.
Other benefits include better record-keeping, increased frequency of inspections, and enhanced data accuracy. With digital records, companies can track the condition of assets over time, ensuring that maintenance is performed proactively rather than reactively.

Inspection Standards and Formal Inspection Bodies
Many industries have strict regulations requiring regular inspections to ensure safety and compliance. These standards are often set by organizations like API and ASME, which establish guidelines for proper inspection procedures.
Inspection Standards
Standards organizations create rules that must be followed during inspections, especially for high-risk assets like pressure vessels, boilers, and nuclear power plants. These standards ensure that inspections are conducted consistently and effectively.
Formal Inspection Bodies
Formal inspection bodies are responsible for verifying that inspections meet the required standards. These organizations employ trained inspectors who evaluate the quality of the work and ensure that all procedures are followed correctly.
While standards organizations may not endorse specific tools, formal inspection bodies often have their own guidelines for acceptable inspection methods. This means that drones can be used as long as they meet the required data quality and safety standards.
Do Formal Inspection Bodies Allow Drones to Be Used in Inspections?
Most standards organizations are flexible regarding the tools used for inspections. As long as the data collected meets the required standards, drones are generally accepted. Some formal inspection bodies have even certified drone-based inspections, recognizing the value of this technology in improving safety and efficiency.
Drone Inspections by Industry
Drones are being used across a wide range of industries, from agriculture to mining. Each sector has unique requirements, and the right drone can make a significant difference in the effectiveness of inspections.
For example, in agriculture, drones help monitor crop health and optimize irrigation. In construction, they provide aerial data to track project progress. In the energy sector, drones inspect power lines, wind turbines, and oil rigs, reducing the need for manual inspections in dangerous environments.
