Flyability
Safe Drones for Inaccessible Places
Flyability have built a solid reputation for creating the world’s most advanced indoor and confined space inspection drones. As the official Channel Partner for Hong Kong and Macau, Dronesurvey Asia provides full sales, after sales and servicing support for the Elios range and Elios accessories.
More than a flying camera: a powerful data-harvesting tool.
Relying on the power of computer vision and SLAM LiDAR, Elios 3 is a versatile indoor drone platform, opening doors to a world where performing systematic inspections does not require months of training, and where reporting is done intuitively on a 3D model of your asset, with full situational awareness built into the piloting app.
Powered by FlyAware™
FlyAware™ is the unique combination of computer vision, LiDAR, and a powerful NVidia graphic engine. A centimetre-accurate indoor GPS, FlyAware™ builds real-time 3D maps, enabling the drone to sense its surroundings instantaneously. Today, Flyaware™ allows for groundbreaking stability and accurate locational awareness. Soon you will see complex confined spaces inspections performed in full autonomy.
3D Live Map: complete locational awareness
The on-board LiDAR constantly scans the surroundings to deliver a high-density point cloud map. This map is displayed in the Cockpit App in real time, giving you exceptional locational awareness. A real-time 3D view of the drone’s trajectory and environment provides crucial data. If visibility inside the environment is compromised (due to dust or moisture) you can continue to navigate your way safely.
Live Map in Action
This video shows the on-screen display in the Cockpit app, while flying the Elios 3. Note the 3D map in the lower right corner. The pilot is able to flip the map to the main screen if visibility on the video feed is compromised.
Extra Reassurance in Challenging Environments
The Elios 3’s Intelligent Autonomy ensures extra piece of mind for complex indoor inspections.
1. Smart Return-to-Home
With Smart Return-to-Home, the drone autonomously returns to the take-off point, intelligently navigating by the shortest return path, and dynamically avoiding obstacles. This is the power of FlyAware™ and autonomy in action!
2. Resume Inspection
By using Smart Return-to-Home to return safely to the landing point, Elios 3 “remembers” the path. Insert a new battery, start up, and hit “Resume Inspection” — the drone automatically flies back to the last RTH point, ready to continue your mission. Simple, easy, safe… and efficient!
Multiple Power Source Options
Choose from standard or high-capacity batteries, or for unlimited flight time, the new Tether Power Unit.
Standard Battery
The flight-safe standard battery gives up to 9 minutes of flight time in most situations.
High-Capacity Battery
The High-Capacity battery delivers 50 percent more flight time (up to 13 minutes) over the standard battery.
Tether Power Unit
The Tether Power Unit gives you almost unlimited flight time by using ground power through a 50m kevlar-reinforced cable.
The Elios 3 tether unit delivers continuous power for long, stress-free operations. By connecting to a wall outlet, generator, or compatible portable power station, it converts 100–240 V AC into high-voltage DC, delivered to the drone through a 50 m (164 ft) Kevlar®-reinforced cable.
With steady power from the ground, pilots can eliminate mid-mission battery changes and stay focused on the inspection. The Tether Power Unit offers:
Full Mission Focus
Removes flight-time constraints, allowing the pilot to focus entirely on the mission.
Uninterrupted Efficiency
No battery charging or swaps. Pilots stay on task, maximising mission output.
Extra Peace of Mind
The tether serves as a safety lifeline, giving pilots confidence in every mission.
Unique Anti-Flip Swivel
Fly as freely as if untethered. The anti-flip swivel secures the cable while allowing it to move freely around the drone, eliminating disturbances from the tether. This ensures perfect stability, even during sharp manoeuvres or a cable snag.
The swivel rotates 360° around the drone, allowing the tether to attach from any direction. This rotation removes directional constraints, ensuring inspections are never limited by tether orientation.
Easy Tether-to-Battery Swap
Easily switch from tethered to untethered flight.
The air unit connects the cable to the drone and can be swapped with an Elios 3 battery in seconds. This lets pilots fly beyond the tether’s reach, ensuring complete data collection in all conditions.

Backup Battery
Land safely if there’s an unexpected power outage.
The tether ground power unit is equipped with a backup battery either Elios 3 standard or high-capacity battery that automatically supplies enough power for a safe, controlled landing during unexpected power loss.

Supercharged Data Quality
The fixed payload can be tilted remotely, giving you a fully unobstructed field of view 180° up and down.
Inside is a 4K camera, a thermal camera, and a distance sensor.
The lighting system uses industry-leading oblique and dust-proof lights, designed to spot pitting and cracks in surfaces.
