What????!!!

What????!!!

Indoor interference. You would be surprised at the interference from WiFi, microwaves or anything that gives off magnetic fields.

Neither wifi nor microwaves produce magnetic fields, and this incident had nothing to do with "interference".

It's perfectly OK to fly the drone indoor as long as there is no intermittent availability of GPS and the lightling is good enough for vps to work. I have done it with my M2P and also Mini many times. Never had any problem. I don't think the problem of the OP is solved. The reason of the drone's behaviour is yet to be identified.

 

[Greekislandlover]

I realize that everyone is just trying to be helpful, but this thread has become a complete mess of misinformation. It is most unlikely to have been an RTH event because (1) it is unlikely to have disconnected from the controller at such close proximity and (2) because RTH that close to the home point doesn't include ascending. It is unlikely to have been ATTI mode because (1) indoors it will always try to use VPS and (2) it will not use obstacle avoidance or climb uncommanded in ATTI mode. It is likely to have been some combination of VPS and GPS positioning - this kind of issue has been seen many times when flying indoors and getting an intermittent and unsteady position lock.

And also note that the aircraft flight logs will not be readable except by DJI.

I agree, but I also agree that the original poster has learned an awful lot about drone behaviour at no cost! I think this thread has been useful.

1, without GPS lock it will drift about depending on wind, or currents it's generated itself by being a bloody powerful fan.

2, if it switches between ATTI and GPS it's gonna behave unexpectedly, so make sure there is a good GPS lock before going anywhere, and it knows where to come back to.

3, without the phone connected you have no idea what mode it's in, and no idea of any warnings the drone is giving you.

4, obstacle avoidance is not by any means perfect. In the case of his drone (MA2) it has no upwards sensors, so in a confined space if it senses something below it will go up - and crash into obstacles it can't see. In the case of mine (Mavic 2 Zoom) it does have upwards detectors so if it goes towards the ceiling it goes down again and tries to find a spot midway in the room.

5, as someone said above, it's an aircraft, not a housecraft. it's really not intended for indoor flight. If you are going to take off indoors be prepared for odd things to happen. If you were taking off outside with GPS lock, and phone up and running this would not happen unless you chose to take off under a tree - which would be bonkers.

I am afraid I cannot agree.

Besides ATTI and GPS, there is a mode called OPTI mode which works very well indoor at least for my M2P and Mini. DJI did demonstrate, in many exhibitions and their shops how well it works so their drones are clearly designed to fly safely indoor as long as the environment allows the VPS to work effectively, ie,

(1) sufficient lighting,
(2) clearly discernible patterns on the ground and
(3) the height is within 11 m from the ground.

I don't think we have sufficient evidence to come to the conclusion that the problem encountered by the OP was caused by weak GPS.

Besides ATTI and GPS, there is a mode called VISION mode which works very well indoor at least for my M2P and Mini. DJI did demonstrate, in many exhibitions and their shops how well it works so their drones can definitely be flown safely indoor as long as the environment allows the VPS to work effectively, ie, (1) sufficient lighting, (2) clearly discernible patterns on the ground and (3) the height is within 11 m from the ground.

Hi, I'm not sure anybody has come to any conclusion as to what caused the behaviour - everybody is just trying to offer up possibles based on the limited information given.

The poster has learned (without crashing the new drone) that for a variety of reasons the on board systems have limits. And there is a need to learn about how to stay safe, and be aware of these limitations - which is my point.

 

[RSDonovan]

My first rule is no GPS lock, no take off. So far it has worked for me.

Maybe take off should be disallowed without GPS

 

[swooshdave]

Maybe take off should be disallowed without GPS

There is nothing wrong with flying without GPS... if you know what you are doing. Or maybe there's a case where the take off spot doesn't have enough satellite coverage.

But certainly for novice flyers the rule of thumb should be that until the little satellite icon isn't red don't take off.

Except that much of the information given is simply incorrect. Many people reading this are going to end up with a completely incorrect understanding of how these systems interact.

Like everyone here I'm scare to death of a fly away.

Despite the number of times you might see people posting about a "flyaway", there is no such thing.
Flyaway just means .. I lost my drone but don't understand why.

Your drone is much easier to fly than you imagine.
The trick is to not let this fool you into getting too adventurous too early.
After you have the basics, there's still a lot to learn to master drone flying.
Do your early flights in a large open area, well away from trees, buildings and obstacles.
Be afraid, very afraid of trees, buildings etc. They are involved in most incidents.
Read up on return to home procedures, practise using RTH and cancelling it so you understand how it works and how you can resume control in an RTH situation.

HI I'M HAVING PROBLEM WITH MY TABLET CONTENTION. .
THAT SAID I TOOK THE DRONE IN MY GARAGE AND DID SOME TROUBLE SHOOTING BEFORE CALLING DJI SUPPORT. (SWAP CABLE AND PHONES, TABLET)
LASTLY I FLEW IT WITH JUST THE CONTROLS ( JOY STICK DOWN AND OUT) THE AVOIDANCE SYSTEM WAS ON . SO THEN GOT IT UP AND HOVERED ( YOU CAN CONTROL THE SEED SWITCH I HAD IT IN (N) THEN WENT TO LOWER SPEED, IT DID , AND I WENT FORWARD AND THE DRONE STOPPED THEN TRIED TO GO UP TO AVOID THE OBJECT THAT WAS IN FRONT OF IT . SO I PULED DOWN TO STOP IT FROM CRASHING INTO THE CEILING . FOR MY MAIN PROBLEM . UNIT UNDER 14 DAY FREE REPLACEMENT WARRANTY SORRY FOR THE GRAMMAR NOW THE WAIT AGAIN
#SAFE #RESPECT #HAPPY FLYING
