I am wondering if anyone else has experienced a situation where a mini pro 3 refused to land?
I had an experience today where my drone would not land due to 'detecting' an unsafe landing area, but I could not override by holding the throttle down. I could not land anywhere else due to jagged rocks and powdery snow. The drone would not self force land itself despite going past critically low battery levels (time remaining dropped to zero).

Eventually it started to lose the ability to hold a steady position, and rather than simply waiting for it to run out of battery completely and fall, I managed to grab it from underneath and pull the battery out.


thanks
Ian

I don't have a Mini 3 but do get these warnings at times with other DJI drones.
I have the impression, though I may be wrong,  that it may be necessary to 'accept' the message by touching it etc., after which the down stick will work. I am sure someone will correct me if I am wrong.
I am pretty sure you could replicate the situation in a safer place to test to see what happens.

With regards to the grabbing it and pulling the battery, I would suggest 2 alternatives to pulling the battery.
1) Hold your hand still and simultaneously hold the throttle closed, if the drone 'thinks' it is still /has-landed the throttle closed position would normally shut down the motors.
2) Tilt the drone so that the props are vertical, this may shut down the motors and 'snatch and twist' is used by some peoples a routine method of hand catching....personally whilst I land a drone in my cupped hand quite a lot I think snatch and twist is best left for emergency use.

Push UP on the stick, then move it to a better location to land.

Yes, cancel the message on the screen, than down stick works again

Hello, Ian.  Thank you for reaching out and we're sorry to read about the refused-to-land concern you're experiencing with your Mini 3 Pro. Have you tried different flight environments to isolate this concern? Please follow the steps below to troubleshoot the issue:
1. Please check whether the remote controller’s control stick mode and the control stick operation are correct. If the control stick mode is Mode 2, push the left control stick down to land.
2. Calibrate the remote controller and ensure that the remote controller’s control stick can respond normally.
3. Check whether the landing ground meets the conditions (for example, whether the ground is flat, or whether there is a water surface). For drones with a landing protection function, when the Downward Vision System works and the ground does not meet the landing conditions, the aircraft will hover and wait for the user’s further operation.
4. Avoid flying through clouds or in a heavy fog environment, which will affect the Downward Vision System.
5. Remove any payload under the aircraft which may affect the Downward Vision System.
6. Make sure everything is updated:


Additional Notes:
· The Downward Vision Systems work best when the aircraft is at an altitude from 0.5 to 30 m if there
is no GNSS available. Extra caution is required if the altitude of the aircraft is above 30 m as the
Vision Systems may be affected.
·  Keep the sensors clean at all times. DO NOT tamper with the sensors. DO NOT use the aircraft in
dusty or humid environments.
·  DO NOT fly when it is raining, foggy, or if there is no clear sight.
Check the following before each takeoff:
a. Make sure there are no stickers or any other obstructions over the Infrared Sensing and Vision Systems.
b. If there is any dirt, dust, or water on the Infrared Sensing and Vision Systems, clean it with a soft
cloth. Do not use any cleanser that contains alcohol.

Thank you for your understanding and cooperation.

Push UP on the stick, then move it to a better location to land.

As the post said, there was no other place to land

Thanks - will remember those tricks if it happens again

You didn't understand what he was asking about at all.
None of your post is any help to him.

I would suggest you 'practise it', I find experiencing these things is the best way to 'remember' them, plus it helps remove the panic.

It happens sometimes. Grab the drone from beneath and flip it over. It will stop the motors.

In some situations, this message is not present. I recently encountered this myself.

Hi, Labroides. I'm sorry for any confusion and if you feel this way regarding the statement provided. To clarify the information, if in case the drone would not land due to 'detecting' an unsafe landing area there's a possibility that the concern is regarding the Downward Vision System since it is the one detecting any obstacle detection and avoidance. It was also mentioned that he could not override by holding the throttle down, which might be a problem with the remote controller that's why it is included in the steps above. We hope that this clarifies the provided suggested resolution. We'd like you to know that we appreciate your valuable feedback. Thank you for your understanding and support.

You could have hand landed.

I have used that when I needed to land on a boat in the open ocean.

This happens to me from time to time as well.  It doesn't want to land with all the objects it sees close to itself.

Click on the ... in the upper right corner of the controller
You will be on the Safety tab
If you can see the done and it is safe to land, turn Obstacle Avoidance Off
The done will now pay attention to the sticks and do whatever you want (including crashing into whatever it was worried about crashing into)

Thanks for the suggestion - I tried turning off obstacle avoidance but it still would not land (and when I went to grab it from below it did try and move away from my hand).  This makes me think it was an issue with the controller not getting the override or obstacle avoidance signal to the drone.

Hi Gamora

Your suggestion of the controller issue makes sense - I also tried turning off obstacle avoidance, however the drone still tried to avoid my hand when I went to grab it, which suggests that it was not receiving either the throttle override or obstacle avoidance commands. Will do updates and hope it doesn't occur again

It's not possible to turn off the downward facing sensor.

IR sensors always work

This will always happen due to the downward sensors, its easy to overcome and i welcome it doing this as it gives me time to assess.
Once it stops ascending, apply full stick down. I don't think i wait till it stops, i cant remember now.

This has happened to me a couple of times with my Mini 3 Pro, also.  I was fortunate enough to have another suitable area close by to fly to and attempt landing again.  I did so, and it landed fine.  I was curious as to why it wouldn't land but just caulked it up as a weird anomaly.  Sometimes, I think these newer drones are just a little too smart!

Hi, Ian. Thank you for the update. Hopefully, that will fix the issue but if the issue persists after the above troubleshooting methods have been tried and doing the helpful suggestions of the co-pilots, you may consider sending the unit in for a proper diagnosis.  You may submit an online repair request through this link: {https://repair.dji.com/repair/index}. If you need assistance with creating a ticket, you may contact DJI support at https://www.dji.com/support. Your kind understanding is appreciated and thank you for your continued support. Safe flying!

You don't grab it. You land it on your hand.

Drey. I Posted at 11-15 05:18

and the thread's  title and subject are what????    It 'was not obeying a command to land' or for some reason not obeying a down-stick command when 'low'......wouldn't  that make it  somewhat difficult to "land it on your hand"
