Heliguy Recommendations to Avoid User Error Flyaways

Flyaways are a worrying thing for all drone pilots from beginners to professionals as they can result in a potentially deadly crash or the loss of a drone. Following an investigation by our Technical Team, we discovered a large number of flyaways are caused by pilot error and could be avoided.

Here are Heliguy’s top causes of flyaways and our recommendations to prevent them occurring to keep your drone safe.


 

Flying Your Drone Out of Your Line of Sight

Cause – In the UK, the CAA’s Dronecode states users must keep their aircraft under 400ft (120m), within 1640ft (500m) and in their line of sight. Using the aircraft’s camera alone means you only have sight of what’s directly in front of you leaving you open to collisions which may cause a potential flyaway.

 

Heliguy Recommend – Always keep your aircraft within your line of sight. This will ensure if an error does occur, you will be able to guide it back to yourself safely. If you lose sight of your aircraft, try to regain orientation by using the camera or activate the RTH function.

Scout out the area you’re flying in to make sure you won’t encounter any issues.

Some pilots may find it easier to control their aircraft as part of a team for added security.

 


Home Point Not Set / Updated

Cause –  The RTH (Return to Home) is a useful function that can be used manually by the pilot to land the aircraft at the touch of a button or automatically when a battery is low on charge or the signal from the remote controller is lost. The automatic functions are useful safety measures to give an added level of peace of mind when flying your aircraft. A Home Point should be set before each flight for the function to be used as if the signal is lost from the controller or the battery is critically low, to avoid a flyaway.

 

Heliguy Recommend – At the beginning of each individual flight, set a new Home Point where you want your aircraft to land, this is usually where your flight begins. Make sure you have a least four (five recommended for flying) GPS bars and double check the Home Point has been set before setting off.

When setting your RTH, also confirm the altitude is set higher than any objects in the surrounding area. This will cause the aircraft to rise above any objects prior to flying to the Home Point, avoiding a collision. The aircraft can also be set to hover if this is required.

For another level of safety, always turn off the aircraft before your controller is switched off.


Compass Accuracy

Cause – If your aircraft’s compass is not accurate, flyaways and crashes may occur. This can be if the compass is not calibrated prior to your flight or if interference occurs during your flight.  Compass interference can occur if the aircraft is launched from a metal object such as a car bonnet or your aircraft is flown near tall structures or antennas.

 

Heliguy Recommend – You should calibrate your compass before every flight to ensure it is 100% accurate and up to date. The calibration process takes less than a minute before your flight and can help prevent a flyaway.

Make sure your compass strength is strong before you begin your flight.

Never launch from a metal surface as compass interference can occur. This includes cars, balconies or metal rooves.

Pilots should also know the area they’re flying in. Avoid flying near any magnetite, tall structures or metal buildings. These can all cause compass interference.

 


Signal Interference

Cause – Like compass interruptions, signal issues can cause aircraft flyaways or crashes. The interruptions can occur when your aircraft is flown too close to powerlines or if a large object is between the pilot and aircraft.

 

Heliguy Recommend – Scout out the area you’re flying around and make sure you’re aware of any powerlines or anything that could come between the controller and the drone. Avoid flying in areas where this could occur.

High-Intensity Radio Transmission Areas (HIRTA) can also cause signal interference which may lead to flyaways.

 


User Not Experienced in ATTI Mode

Cause – ATTI Mode can be selected manually on the majority of DJI aircraft. This mode disables the GPS, GLONASS and obstacle avoidance settings and will only maintain the aircraft’s altitude. The mode is great for people who want to take full control of their drone without any limitations, however, if the GPS or compass signals are lost, the aircraft will enter ATTI Mode. This can be scary for a more inexperienced user as the aircraft will drift in the wind and may lead to a flyaway or crash.

 

Heliguy Recommend – If your aircraft is capable, practice flight within the ATTI Mode in a safe location. Get used to having to combat the wind without the assistance of your aircraft. This will make it easier to take back control if it occurs whilst out on a mission.

Also, remember that you can use your visual line of sight to control the drone, or if you’re disorientated, the camera can be used to find your location.

 


These recommendations will help to prevent flyaways that can be prevented keeping your drone safer.
