Is it normal that my Mini 3 Pro always wants to land immediately when flying in the fog? Shouldn't it continue flying if it has connection to 21 sattellites?  Thx

Mine just states 'low visibility, fly with caution'. What do you mean...are you saying it tries to force land because this is not what I am experiencing.

Yes it stops abruptly and saying “landing” and I can’t control it

And is the visibility super low?

Define "super low"?
2-3m or so.

That's plenty of visibility.  Cant see that causing issues at all other than warning about it.

I assume you've tried calibrating the sensors using DJI Assistant?

In other drones it is not uncommon, can't comment on the mini 3.
But is it wise to fly in such conditions?  You risk water getting into the drone, perhaps ice formation, not being able see something in time to take avoiding action and not being able to see the drone full stop.
If something went wrong and someone was injured as a consequence its going to be your neck and wallet on the chopping block.

In most countries its illegal (vlos rules) unless theres a hole with clear sky to punch through.

i thought the whole idea around vlos is so you can see not just your own drone but also so you can scan the airspace in and around your drone for other aircraft?  how can you do that when it's foggy?

It is not legal, but most importantly it is not responsible.

It is very common as the sensors see the water particles as an object, be it landing or horizontal sensors. At least with the front and back, they can be turned off with a flick of the switch.

Its not really about where you are or folks being around, its about you being able to see incoming aircraft.

Very true. Although I was well below max altitude allowed by law

Hi,

Only reason for this is that the bottom height sensor measures false height, due to the fog.
This will force an autolanding.

Measuring 0.5 meter false height AND stick down = autolanding.

Nothing you can do about this, as this sensor cannot switch off. It is always on.....

cheers

You cant fly *in* fog.
Most countries rules state that clear.
If you cant see the drone and have no spacial awareness of the airspace its not VLOS.

You can fly up through a hole in the fog provided you keep it in sight but i dont know anywhere where its legal to fly through or in fog.

Auto-landing can be disabled by workarounds.

Being unable to disable OA/VPS in the Mini 3 is problematic in a number of scenarios.  I miss that option from my Mavic 2.

Rather than debate, I'll just fast forward to the part where understanding is achieved.  The airspace....  Anyways, enjoy and have fun.  Be safe!

I think a "hole" in the fog could be called into question in regards to Article 241 as you cannot see the whole of the airspace, probably much the same as flying from within a city with high rises in the way. If something is blocking your view be it even from just one direction then you are not able to ascertain flight traffic from that direction. Also, fog can reduce sound travel therefore any air traffic could be on top of you sooner than normal.

In the UK we have the ANO (Air Navigation Order) and within that we have CAP 722, guidance on the law for UAS. If there is one article within that that one should follow and that is Article 241, its a catch-all, and that is...

A person must not recklessly or negligently cause or permit an aircraft to endanger any person or property.

Whereas before, we were only told to follow the drone code, it was just a really condensed pamphlet, now when you google Drone Code, it should point you to here https://register-drones.caa.co.uk/drone-code it now expands on the original drone code and also, there is a section there;

Background: Drones and model aircraft in the law
Some of the key points of law behind this Code.

They do not tell you to read the ANO or other Articles for that matter BUT now this is a big one, we are expected to read it so that we know the guidance and acts.

In the eyes of the CAA or the courts for that matter, ignorance is not bliss when it comes to the airspace. It is up to us as pilots to read and understand what is expected of us. Now i wouldnt tell anyone to read either the ANO (worse than the bible is that) or CAP 722 (you should at least browse CAP 722 though), thats just as bad but nowhere near as bad as the full ANO.

FYI, I'm just letting you know whats what, nothing more than that as i am probably the last person that should be telling others what to do lol

Hello, MetaFlexa. Thank you for reaching out and we're sorry for the inconvenience. It is caused by the fog as thin air will affect the aircraft’s propulsion, resulting in propulsion overload, sudden descent when hovering, unstable flight, etc. Please avoid flying through clouds or in a heavy fog environment, which will affect the Vision Systems. Have a safe flight always!

Rules and warnings aside, in theory you can put some black tape on your bottoms sensors. They are pretty useless in the fog anyway. Just be careful to tape them really good so that bottom cameras can't see anything other than pure blackness. If not you risk that the drone picks the tape as an obstacle that it will try to avoid by increasing altitude and it will go straight to the stratosphere. Also be careful when landing as the drone will not be able to see the ground and decrease speed before ramming into it.
