Weather…Wet, Wet, Wet

Wishing Well, by Wet, Wet, Wet in the 80’s was a cracking little number. But when you are trying to work with UAV’s it’s not even a one hit wonder. Its like Jed-wood’s attempt at the Eurovision song contest. Nil point!!Autum Wet Path

Weather, in all its forms, dictates Ikopta’s work pattern. And sometimes the work just can’t wait for the weather to be right, so what happens then?

UAV’s are expensive, they are expensive to buy, its expensive to get qualified, it’s ridiculously expensive to insure, and if/when it goes pear shaped they are expensive to repair (if they can be). Money, Money, Money. ( I feel another tune coming on).

Boredom has set in, and to break from editing YouTube has distracted me. This is great piece on YouTube I found of how NOT to fly a DJI Inspire: Thank you to Transito for posting, sorry for your loss.


What went wrong? As with most YouTube uploads of drone/UAV crashes, its down to pilot error in one way , or the other. And it can happen to anyone at the controls of a UAV. From the video, the pilot has lost line of sight of the UAV, fun to do, however this is against the regulations set out by the Civil Aviation Authority (CAA)in the UK. As a Ikopta UAV pilot, you have to keep line of sight at all times, to allow you to see any intrusions into your operational flight space, also to insure that the craft is in contact with the transmitter. Common sense should tell you that if you can see the UAV because of an obstacle, then there is a good chance that the transmitting signal will be interrupted as well. The UAV craft will then go into failsafe mode, as it is designed to do by DJI, and this is when pilot error number two happens.

All qualified, CAA approved UAV pilots in the UK will tell you, its all about the pre-flight checks. Robust check lists may take longer than the flight itself, and for good reasons, they are essential. Error two in Transito’s video,  when signal was lost between the transmitter and UAV craft, the Dji Inspire went into failsafe mode, returning to its preset home point. In this instance, as with most, the pilot did not complete the proper pre flight checks, did not set the correct home point in clear, safe area. The pilot also failed to set the correct fail safe return to home height for the area that there were operating.

The result is what you see in the video. Embarrassing on a commercial job if you ditch your bird in front of the client, and I can’t even start to imagine how they managed to rescue the Inspire from the tree. In the UK under the just reporting ethos of the CAA, by which all qualified UAV pilots adhere, this incident would be reported. Sometimes, when you perform a task day in, day out it becomes automatic, we switch off a little to the detail. It’s only when it goes wrong that we wake up to failings in our systems.

Moral of the Video? FOLLOW YOUR CHECK LIST! FLY SAFE! Or write yourself an amazing operating procedure for UAV tree rescues.
