I am not kidding! I'm still totally shocked!I want to explain what happened. We have pretty cloudy and autumn weather. The clouds were low so I decided to try break through the clouds today.
I started my Spark normally and started to climb. On approx. 350m I already hit the bottom of the clouds. I observed that the altimeter in the DJI GO app started to go crazy, it jumped from different heights back and forth, I continued to climb. When I reached the inner cloud my altimeter showed 0m !? I could not see anything - because I was in the cloud. I could not descend anymore and then I started to panic! I tried to get more height and then I lost signal, and it randomly connected and disconnected. I could not descend as it always showed 0m altitude. It went to return to home and stuck in the clouds because it thought it's < 1m above ground.
I knew I am screwed. I was so worried and scared because I knew that thing will come down like a brick from over 400m (thats 1200ft!). I flew in populated area and there is a main road and a lot of houses...
When the battery went down I took cover and waited, hoping that thing will drop in the lawn. But then I heard a huge crash noise... It came down at my neighbours house, I already thought that thing went through his roof!
But I was lucky, that thing hit the concrete roof of his balcony...  I had a loc8tor but that thing flew off on impact... The battery flew off over 15meters on impact. I knew, my drone is gone. But when I climbed on the roof I saw the Spark with only the housing a bit open (the lid of the drone) and 2 props missing... I took it and pressed the housing together, it snapped in. I then put in 2 new props and started the drone with a fresh battery. Using my smartphone I could take off and this freaking thing IS STILL WORKING!
I CANT BELIEVE IT... It only got a scratch on the back left prop arm. That thing is working guys, the battery too...

BUT...
Now the question. Why the hell the altimeter goes crazy when going into a cloud or mist? How can I override the controls to descend when it says 0m?

First it got to 475 metres because you were pushing up on the throttle, it was then that it seemed to gradually increase height after first RTH kicked in.
I think what might have occurred is VPS was showing height at 1.5 metre it may well have locked on some clouds, from there it tried to climb to whatever RTH height you had set and then descend but you kept moving sticks which can result in stopping RTH it was doing its best to land but I'm thinking it thought it could land on a cloud so this had the effect of continually halting RTH until it ran out of battery and fell from the sky.

You should sync your flight to dji cloud and get their analyses .

While cloud seems low it's probably not quite as low as you imaging. Climbing to 475 metres is not a very wise thing to do, you are very clearly in manned airspace plus you have no VLOS , putting other aircraft in danger is not acceptable and will not help drone flying.

Thanks for the info. The only aircraft that flies here are above 25000ft so I doubt I put other aircrafts in danger. BTW I am totally sane and I don't need such common sense advices.. I would not fly if there are other aircrafts around.. I mean, I am not an idiot thus I dont like to be treated like one.

My guess is that the Vision system couldn't see through the moisture/particle content of the cloud and assumed it was a solid surface and thus thought it was on the ground.  I can see very easily how this would happen.  Not a very common scenario I would think.  However, we did have a really big fog come through the other morning and hang around for a few hours.  I actually thought about trying to fly in it, but after your experience, I'm glad I didn't!

That is amazing that your Spark survived a fall like that onto a solid surface!  I know everything seems to be working now, but I'd personally recommend taking baby steps over your next few flights to make sure that things are definitely working 100%.

Thanks for the info. The only aircraft that flies here are above 25000ft so I doubt I put other aircrafts in danger. BTW I am totally sane and I don't need such common sense advices.. I would not fly if there are other aircrafts around.. I mean, I am not an idiot thus I dont like to be treated like one.


Well i think you will find that flying above 120 metres is illegal in your country, also I'm confused if you could not see above the clouds how did you know for certain there were no low flying aircraft I'm sure that they have helicopters and small aircraft using airspace in Croatia.
Nobody called you an idiot, and if it's common sense then maybe you should use it.

I don't think you should fly over places where some kind of risk exists when the drone comes down (buildings, people, ..). Personally, I'll never do that. I and other drone users don't like to be in the newspaper with the message that the spark has hit somebody. And from that heigth, it might be lethal.
I'm not saying you're an idiot but please be more carefull before starting your next flight.

Kloo Ge will do so. I am still sceptical that the drone works flawless after that impact.

Hallmark, I live here. And I really doubt that someone will fly on VFR between mountains when there is 0 visibility. No helicopters here either, not in this conditions. Maybe we have other understandings what common sense means.

Ernieken, I wont do that again. Thats for sure! Lesson learned. But no matter if 150 or 500m, kinetical energy is the same. I lost my confidence into the Spark.

read the manual.

DJI speaks very clear in the clouds and fog ... not fly inside is not recommended !!

beginner's mistake. I'm sorry, I lost 1 hour to read it all ... and still I do not know the spark potential yet.

fly to 500mt? yes, but with cloudless sky ...

good luck for your next flights!

Dear all, can you please explain to me why we are discussing a case where somebody has not only intentionally breached all European laws concerning the flying of drones, has put other people at serious risk,  confirming just all the prejudices we have to continuously struggle against, lying to us about air traffic in his area which is anyway not his business to control or oversee, going out of RC range with the Spark if he has been in CE mode and then complaining that the Altitude meter was not working properly and requesting our time to answer this question?
What comes next would be my only question...

its a common sense thing.  out where my farm is lot of helicopters (medical/emergency) that fly a specific paths and routes, and most small planes fly similar paths..  but they almost always crossing  several miles over to the  east/south east and south..  so it is possible to know where they are and will more then likely be going.   doesn't mean they wont or can't cut across and cause issues, but not impossible to study it..and feel comfortable taking a small drone up for 10 minutes with "limited risk"   if its like 30 minutes up there then i would side with the more shouty people.  but spark isn't going to be staying up there for very long...

My guess is that the Vision system couldn't see through the moisture/particle content of the cloud and assumed it was a solid surface and thus thought it was on the ground.  I can see very easily how this would happen.  Not a very common scenario I would think.  However, we did have a really big fog come through the other morning and hang around for a few hours.  I actually thought about trying to fly in it, but after your experience, I'm glad I didn't!

That is amazing that your Spark survived a fall like that onto a solid surface!  I know everything seems to be working now, but I'd personally recommend taking baby steps over your next few flights to make sure that things are definitely working 100%.

i agree! it is the VPS kicking in causing the spark to "panic"  once the VPS kicks it it usually 'correcting" the altimeter as well..  meaning you wont have a clean reading in such cases.

i cannot remember for life of me if the spark allows you to turn off the VPS/downfiring sensors or not..  i know it doesn't have landing protection so it can't distinguish a cloud from the ground like the mavic has...   would be stupid if DJI didn't give the spark a toggle to disable VPS/downfiring sensor..  not like the spark has ultrasonic sensor to test if cloud if ground or not..

Just wondering if we can draw any conclusions for our benfit. If altitude reading suddenly goes to zero, is this because visual control has been automatically invoked?
If so the ability to turn it off might be a life saver. Since gps is still in control, (since no atti indication registered), one could then descend as required.Might be useful in other scenarios.To prove this, all one needs to do is fly at say 35 ft over a 25 ft building and watch the height reading.
Just an idea.

That cannot be the point. In the US you probably have no idea (and very likely can't, unless you would read European newspapers or watch European TV) how hard times are getting for us drone pilots here. We have got a really negative image because of few insane persons who have decided that no laws or regulations apply to them. And the guy at stake reports himself that he realised that his Spark was falling down from high altitude and with high speed in a densely populated area (see post #1) and he has intentionally taken that risk. There is nothing more to say in my opinion.

I had similar problem one day with light fog (not inside a cloud). When the sensor gets wet start to fail. If it is completely wet it marks 0 and you cannot go down. So, the first opportunity I had I returned home. Never fly with fog, even very light fog.

It is incredible that the dron supports that fall, I imagine the propeller guard were installed.

true, you are correct.  but i also feel like that shouldn't make the good people who are mindful be pushed away either..  idiots will be idiots, regardless..    sadly restricting drone pilots only does one thing.... limits good people, and allows idiots full freedom to be idiots and make it harder for us.  

that's why i dont listen to limitations and restrictions and listen to common sense and common knowledge..  meaning obviously not going to fly over as hospital with helipad or push my aircraft up into path of a plane or anything..  and ill stay away from airports and military zones..  but blanket limitations are stupid if you know what you are doing..


its like the gun debate we sometimes have in the US and the media..  reality is, i carry a gun, i have a permit for consealed carry, i hate politics and all of that, im idependant on that matter, but its same logic, if gun laws got too strict too tough then that hurts good people like me and others that carry or have home defense..  and doesnt slow down people that are already out for bad, not like they are legally purchasing a gun anytime soon to commit crimes..  not like requiring us to have training with our guns, that gangs on the street any better or worse off.. etc etc..  so blanket limitations and requirments do litterally nothing to help anyone....idiots will be idiots reguardless

I agree I think for many reasons option to disable VPS would make life a lot easier, I have thought about this and why we are blocked from doing this and my only conclusion is because of palm launch if you forget to turn back on you may have a lot of problems.

ah, i was struggling to remember if it is option or not.. so stupid you cant..  almost like dji wants people to crash..

if the spark has mini ultrasonic sensor then no option to turn off vps is ok..  because ultrasonic will see nothing there and stop it from being stupid..  like dji half assed it.. no ultrasonic and no way to disable vps..rip

I agree, but even notifcation that the a/c had switched  to vps would be useful. All such  info for the pilot would be constructive. Maybe in fog it tries to climb a bit as altitude is zero, but continues to read zero even though it expects to have gained height. No wonder it gets confused.
Of course you should not fly in these conditions, but if this is the explanation undulating terrain might produce a similar situation.

ya its stupid.. technically is a indicator VPS is used, but its tiny and easy to miss at the bottom of the screen..  need to be a popup saying potential issue and ask to disable VPS for you.  

on my mavic pro i can disable VPS all together or just disable landing protection (i think is the ultrasonic sensors)

i think the spark needs a "pro mode"  just unlocks certain features, like disabling VPS and other stupid things DJi left out..

so i am the entire representation as a whole of a community of potentially millions??   interesting logic you got there.  i behave myself but i do not obey blanket limitations and will never obey them.  i know how to fly, i use common sense, i have no intentions of causing harm to others...

this maybe the wrong thread to post my opinion on this since the OP did fly dangerously in an area if it crashed way it did it could have caused even more damage than it did..  but my opinion stands that with common sense and common knowledge you should be nannied into idiot level.. but my intial point was that he understood and studied flights around him.. not that he was right or wrong in what he did, (i agree he was wrong)



as for carrying a gun to feel safe, not at all why i carry, i carry for other people who maybe helpless in given situations that require deadly force.  the police take an average of 9 minutes to respond in america..  9 minutes is an eternity give the situations that require use of deadly force.  i have never had to use it, and i hope i never have to, but just incase, it is always with me..

Altimiter is a barometric sensor. Air pressure in clouds can be dynamic, resulting in inaccurate readings. Hence, dont do it, per the manual.

Also, OP is a fool. There is a thing aircraft have called instruments. It allows them to fly without seeing. Commonly known as IFR. You dont have common sense, or any sense. Just foolishness.

Do us all a favor, sell the Spark. Take up knitting.

One fool with a gun decides to shoot an intruder in his home, turns out to he his son sneaking home late. Congrats, y'all got painted with the same stupid brush. So, yes, you do represent a community.

One turd decided to spy on his sunbathing neighbour, now we are all pervs with cameras and have rules created accordingly. Yes, you do represent the community.

Of course, you may be better than either example, but those are the colours by which the general public paint us, no matter how sane you are.

As for common sense in flying: unpopulated area, clearly visible, decide to go to 200m when the law says 100m? Well, you can see there is nobody around so that is good sense.

Flying into cloud over a populated area is senseless.

i dont think the baro was the cause, i think it was the VPS.   i understand your logic but VPS "corrects" readings if it is triggered, clouds and dense fog can trigger VPS...  the spark has no protection or redundancies to know for certain.


im not a cloud expert, but i have flown my mavic in come clouds a few times myself didn't have any issues, but that was with mavic pro not spark, i would be more cautious about skimming clouds in a spark for sure.

Hmm..flying almost 400m, over populated areas, seeing clouds and still trying to climb and posting on the official forum, and still flying after a 400m drop...
I might be the only one but none of those seemed right to me.

In any case, clouds will cause the sensor to think you're at 0m altitude. The clouds will seem like ground to the sensor..it's all mentioned in forums and even dji says not to do so..

ya i think everyone agrees what he did is stupid and a shame.   he did only one smart thing that was study the flight patterns over his area before putting his spark up in danger.  

if he did that over an empty park during a time when no one will be walking over.. then that's "okay"  i'm ok with that.  assuming he made sure no possibility he was going to fly in path of any other aircraft and only person he will possibly hit was himself..

like i'm getting crap here right now, but i wouldn't go skim a cloud in a spark unless i could disable VPS...  even then i wouldn't go skimming clouds over populated areas, it would be at my farm or something equally remote.. i have skimmed clouds in my mavic, but i never did that over people or over vehicals.. i did it over an off limits area with underground mine fires... called centralia..

One thing that I have learned from Spark is if the bottom sensor detects something very very close to it, it will initiate Palm Landing though you have not start Palm Launch nor enable Advance Geature. You may make a test. I have not test with other DJI model.

You all should not complain OP. He is just one among hundred thousands who buy Spark and DJI should be well aware about this. So, DJI should not build Spark to fly higher than 30 m. and further than 50 m. radius to make it safe in hand of most people like OP, ordinary people with average skill. Sell high capability aircraft only to people with licence only.
