Put an end to hazardous inspections and surveys

Underground applications for the ELIOS 3 are extensive. Thanks to its rotating LiDAR sensor, ELIOS 3 provides an omni-directional field of view, ensuring 3D data is collected in all directions. Accurate model measurement and volume calculations are made possible without GPS.

Frequently Asked Questions

In order to operate a drone, do you have to be an engineer or an NDE inspector?

No, it is not required but you should always be aware of the regulations concerning commercial drone operations in your area before flying). Piloting Elios drones is accessible to everyone who has completed the introductory training. Traditionally our clients work in teams of two when running inspections, one pilot and one inspector who can analyze the data on the spot. With this approach, each person can focus on their area of expertise.

How do I train my team?

Flyability has put in place a complete certification and training program that takes drone pilots from discovering the particularities of piloting a drone indoors BVLOS (Beyond Visual Line of Sight), to being able to perform the most difficult indoor inspection missions. The certification tests the pilots on their ability to assess the difficulty of a mission and puts their own piloting skills into perspective. Our training courses are defined and provided by professional pilots with extensive mission track records using Elios drones. Every bit of theory you will learn is backed-up by practical exercises directly applicable to your everyday job as a pilot. Operators following our training courses receive a valuable professional certification, acknowledging their proficiency at using Elios drones.

Do I need to adapt my Standard Operating Procedures?

Asset owners are responsible for deciding whether to modify their SOPs to accommodate the use of drones. Nevertheless, SOPs provide a method to communicate the process changes to employees. As they no longer rely on humans to enter confined spaces for inspection, most of our customers update SOPs to take the drone into consideration.

Can a drone be used as a formal inspection tool?

Several clients have conducted formal inspections using our products that have been approved by classification societies. You can read more about an example in this article:
The thing to note is that drones can't permanently be recognized as a formal inspection tool, since inspectors are agnostic to specific tools. Rather, inspectors can approve a given tool in a specific inspection when they see the data it can produce.

How to process inspection data?

Once your mission is completed, you can simply connect Elios to your computer using the USB port fitted on the top of the drone to import all data in Inspector, our companion software.

After retrieving the flight data, you have immediate access to a high resolution point cloud of your assets that you can visualise in Inspector. You can then review your POIs and document your inspection by taking notes in the POIs, making measurements, and exporting your data as a report.

Are drones intrinsically safe?

ATEX is the European certification given to equipment tested and approved to be intrinsically-safe.

The Elios drones are not ATEX rated / intrinsically safe. It is hardly possible for a drone to be intrinsically safe (none to date).

You will need to perform a procedure to neutralize the environment of the asset you want to inspect like you would do when doing a manned inspection. You still have a lot to gain when performing the inspection with a drone instead of a human. For example, you can use nitrogen to neutralize the asset and send in a drone right away. If you do the same for a manned inspection, the inspector would have to carry a breathing apparatus and you would need to deploy bystanders, which is much more complicated and dangerous.

Can I fly Elios drones outdoors?

Flyability drones can fly outdoors in ATTI mode to inspect outdoor assets. However, it is not recommended to do so as it is much harder to control the drone in ATTI mode. This use case is reserved to experienced pilots only. Keep in mind that flying outdoors is subject to airspace regulations, unlike indoor flights.

Should I insource or outsource drone-based inspections?

It depends on your usage and the regulations in place. Some industries may require a qualified and certified inspector to perform an inspection. In case you would like to outsource, there are service providers that use the Elios drones all around the world.

For more information on outsourcing, consult the following links:

What is the size of the smallest defect the Elios drones can spot?

With Elios 2 & 3, you can capture images with a Ground Sampling Distance of 0.18 mm/pixel when standing at 30 centimeters from the surface you inspect. With this accuracy, you can easily spot defects that are a few millimeters wide such as small cracking patterns in the walls or a hole inside of silos.

Is dust a blocker for drone-based inspections?

Industrial indoor spaces are often full of dust, which makes First-Person View aircraft navigation difficult. Elios drones feature a dust-proof lighting system that allows you to traverse dirty places without losing sight of your objective. And for the extreme cases, you can navigate inside assets relying solely on the live map created by LiDAR and displayed instantly in Cockpit.
