Frequently Asked Questions

General Questions

The Yuneec H520 commercial UAS is a multi-payload hexacopter aircraft built for inspection, law enforcement, security, construction, surveying, and mapping applications in addition to offering cinematic or broadcast-ready imaging payload systems.

The H520 is currently deployed in Law Enforcement Organizations, Fire Departments, Search and Rescue operations, inspection operations and several contractors (e.g. construction).

Our DataPilot™ software system enables users to efficiently and consistently create orthomaps, 3D scans, crop data imagery, for repeatable, recallable aerial flight paths, without requiring 3rd party mission planning/flight control software.

Yes, there are three flight modes. Manual mode, Angle mode and RTL (return to launch) mode. In manual mode, GPS is deactivated and the aircraft requires manual control, capable of holding altitude position-only. In Angle mode, GPS assists position. In RTL mode, the H520 will automatically return to launch point and land.

The ST16S’ intuitive Multi-function 7” Display touchscreen interface with haptic feedback requires minimal training. The three function screens may be rapidly selected via three function buttons at the top of the DataPilot™ application. The touch screen also allows for instant full-screen data, and can be "double-tapped" to return the telemetry and measurement information on the screen.

No. The H520 is limited in payload weight. Conversely, the H520 can access locations that manned aircraft cannot.

New pilots are not required to take any special training courses. However, it is recommended to read through the manual, understand the safety precautions and local regulations as a Commercial UAS, and understand how local regulations and laws apply to its use. Yuneec recommends both practical and theoretical training for the H520 aircraft. Due to the advanced technology that the H520 solution employs, training and stick-time training are dramatically reduced, allowing newer users to generate high quality data or video results in a very short period of time.

5000 meters above sea level. However, in the United States, FAA requires unmanned aerial systems to be within 400' above ground level AND within visual line of sight. Although the H520 has successfully launched from altitudes as high as 15,500', the operational altitude specification is 12,000'. High altitudes will incur shorter battery life (due to density altitude) and reduced precision.

The mission-useful range of the H520 is approximately 1 mile (1.6Km). In ideal LOS circumstances, longer distances can be achieved.

Three payloads are available from Yuneec: E90, E50, and CGOET.

Yuneec-built custom payloads are not available at this point. However, there are third party manufacturers creating compatible payload systems.

Yes, DataPilot™ application allows missions to be planned on a desktop, laptop, or ST16S Ground Control station to avoid outdoor working time. Missions may be stored and recalled for future use.

Yes, DataPilot™ allows for storage/caching of maps from many map providers for access in areas with no connectivity, and provides tools for precise waypoint placement even in areas where no updated maps are available. DataPilot™ allows for maps generated by popular mapping providers such as Bing, Google, Statkart, and Esri.

Yes, in live-scene operations, ground anchor points for waypoint or survey flight may be manually created without a map. This is a valuable feature, particularly for Law Enforcement and Construction applications.

Orange is the standard color for industrial tasks and stands out well in outdoor industrial environment. The airframe is Safety Orange (Pantone 152) to provide stark contrast/greater visibility contrasts in most enterprise/commercial environments.

The H520 does not offer GIS-certified accuracy, as most UAS products do not.

No. Video is encoded to HEVC or .mp4. Still images are JPEG or DNG (digital negative) and are compatible with most viewing and editing systems.

Images are stored in full resolution on the aircraft via the Micro SD port on the camera system. A low-resolution copy is stored on the ST16S for reference

Yes. The HDMI output port delivers a 4:2:2 720 video stream from the ST16S Ground Station, and distribution of video may be achieved in many ways ranging from connection to a cell network, direct cable-coupling with a broadcast truck, or feeding a video village via an HDMI splitter. The H520 records a redundant stream with one file recorded on the H520 in 4K or HD resolution, and the other recorded in 720P on the ST16S Ground Station. Additionally, the H520 may be ground-tethered for constant power, allowing the H520 to remain on-station for long periods of time, allowing for time-lapse, constant feed in temporary gatherings, or as a portable fixed-camera solution.

Virtually any photo or video editing/viewing application is compatible with video or stills from the H520 and its related payloads.

When the H520 initially senses a low battery, the system will first notify the user. If the user does not respond within an environmentally-determined time, the H520 it will automatically enter RTL (return to launch) mode and fly back to automatically land where it was launched.

Yes, DataPilot™ offers flight log export for compliancy.

The built-in sonar system assists in comprehending distance from objects and obstacles. This is not an obstacle-avoidance system.

Yes, users can set the radius and height of the fence through custom settings and set the flight commands of the H520 when the GeoFence function is triggered.

Product Use

Boot-time for the ST16S is approximately 30 seconds. The H520 boot-up time is approximately 5 seconds. Both may be booted at the same time. The aircraft/GCS bind at every boot-up, taking approximately 90 seconds.

Yes, all Yuneec commercial camera systems are hot-swappable, which minimizes down time and improves productivity.

Yes, you may fly the H520 back and replace the battery during mission. DataPilot also calculates the amount of battery needed based on the mission. The H520 and DataPilot™ combined intelligence will return the aircraft to the launch point for battery change-out, and resume any auto-flight from the last point flown. Multiple batteries may be changed out during flights.

Charge time is dependent on the type of charger used. The standard charger requires approximately 110 minutes to fully charge a battery. The optional industrial charger/balancer requires approximately 60 minutes to simultaneously charge two batteries.

The area depends on the precision level of the survey and how much overlap you need for the images. Generally, one battery will cover five to seven acres of property with variables of altitude, wind, groundspeed, and other environmental considerations that may affect coverage area.

Yes. However, although the technology allows for flying multiple aircraft, many countries have regulations that prevent “swarming” (flying multiple UAS in the same area for large scale survey). US users will want to refer to FAR 107.35.

Wind and moisture are the greatest environmental challenges to any UAS.

Horizontal: ±1.5m; vertical: ±0.5m

The larger motors and larger propellers provide for more efficient use of power, heavier payload, and reduced rotor volume (noise) in flight.

Approximately 25 minutes with E90 and 28 minutes with E50 and CGOET payloads.

Service & Maintenance

The Yuneec YES! Extended Service Plans are available for the H520 and the Ground Control Station/ST16S as well as the various payloads.

Users may update the applications in the field. However, a hotspot is required to download updates. Yuneec recommends updates be performed in the office or shop, and tested prior to any flight.

Yes. Yuneec provides a scheduled maintenance guide for the H520 and its components.

We recommend the aircraft be returned to Yuneec, or one of its authorized agents, every 500 hours for a complete examination and overhaul of the aircraft.

Safety & Reliability

The H520 offers geo-fencing, auto-return to launch point on low battery, and auto soft-land in the event of a critical battery. If a pilot ignores the low battery warnings, the aircraft will determine criticality and force-land itself safely.

There are many advantages to a six-rotor platform. Six rotors allow for greater precision and balance in any flight scenario, while six rotors also provide significantly greater stability in turbulence or high winds. Additionally, six rotors provide redundancy. In the event of a rotor strike or foreign-object damage the aircraft is able to continue flight on five rotors. This is of utmost importance in any public safety scenario.

Retractable/extendable landing gear allow operators a 360° rotation of the imaging payload (camera) but also reduce the concern for snag points in leafy or guide-wire environments. Additionally, retractable landing gear reduces drag on the aircraft, providing for smoother, less turbulent flight.

No. Yuneec does offer a third-party solution to provide high water resistance to the aircraft, which reduces risk of water and dust damage. Yuneec highly recommends the use of launch/landing pads to reduce ingest of dust and other debris, providing longer life motor potential.
