UAV Darter waypoints do not always work
Acknowledged, HighPublic


Often the Darter will spin in circles or fly around instead of directly to the waypoint given. Even if it gets to the waypoint it will then spin uncontrollably.

Video here (comment below):


Legacy ID
Operating System
Windows 7
UAV (Unmanned Aerial Vehicle)
Steps To Reproduce

Open UAV terminal and tell darter to move somewhere via shift-click waypoints.

Additional Information

When doing this, it also makes the camera for the gunner VERY unstable/buggy.

Event Timeline

There are a very large number of changes, so older changes are hidden. Show Older Changes

I also experienced this behavior numerous times in singleplayer as-well, but I don't think you can really reproduce this event - the behavior of ArmAs AI is too Sporadic & Inconsistent...

But I have noticed that this typically occurs during very complex missions (Many Units, Waypoints, Scripts, Ect.)...

This is happening to me. I'm in a Multiplayer server, and the camera shakes uncontrollably and the UAV keeps rotating in random directions.

This happens regardless of any waypoints

When I fix this?

Lex added a comment.Aug 25 2016, 3:52 PM

When wait for fixes? Take the time to fix it.

It always happens to me!

Every time that in mark a distant crossing point, it moves for about 300m and starts these turns.

Chubbs updated the task description. (Show Details)Sep 14 2016, 2:01 AM
Chubbs changed Reproducibility from Sometimes to Always.
Chubbs set Operating System to Windows 7.

This is now happening more than ever, I cannot use UAVs at all using their autonomous waypoints and others are getting the same issues according to the comments in the youtube video. Can we get some word on this? Has it been acknowledged at least?

Lex added a comment.EditedNov 3 2016, 2:29 PM

Remember as AI gets into the car. Takes a detour near the car. And at the UAV, only infinite circles.
To the ticket term 1.5 years. Please fix a problem.

I do not understand this bug is easy to appear on bespilotnike. I put two drone in the editor, and a detachment of the enemy. During the game in the editor, drone revolves around the point and can not take the appointed position.
Is there no time to fix it?
for Mission Editor.

Use the UAV to detect the enemy.

Replace the name on - UAV Darter traveling points don't work.
98% of UAV Darter won't reach in a point.
ArmA 3 RC 1.66
You when solve it UAV Darter?

This thing is becoming more and more frustrating since the Falcon introduction with Apex.
It would be nice to use an UAV without the thrilling of not being capable of moving it where needed.

Please guys, please

I'm not quite sure if BIS is acknowledging this bug and it's importance to fix it. This is a big problem for me, since I started playing arma3 two years ago, and since then, nothing was done about it! It is happening 9.8/10 times for me and it is so frustrating, that I started avoiding UAV which is real shame.

Please give me hope that somebody will do something about it in 2017.

Thank you for your game and work, but this really grinds my gears!

Fleeing returns false, however unwanted behavior continues

I thought it might be an altitude problem as I was using 2000m pretty consistently for my waypoints but I just confirmed that the altitude does not matter.  The Falcon waypoint system is completely broken as I tried all of them and none of them would make it even come close to actually getting to a waypoint.  I manually attained 200m, 500m and 2000m before I set the movement waypoint and it did not get there no matter what.  I did get the Darter to a waypoint by using the hold waypoint mode once but only once out of 6 times that I tried.  Otherwise they both spin out of control not seeming to know where they waypoint that I set was.  Also a major bug is that you can't release the autonomous mode at all once you give them a waypoint.  I tried deleting the waypoint and turning off  autonomous in the terminal but they continue to try to get to the waypoint that was set earlier..

Can confirm this. I find that it only happens when you set the altitude of the Darter. If you create a waypoint it will move to the waypoint just fine. If you assign it an altitude it will trip out hard, every few hundred meters.

Lex added a comment.Mar 8 2017, 12:58 PM

@smp1991 Perhaps there is serial communication. But this time, when the UAV cannot reach the route point, assigned to the UAV keeps height. It looks
as loss of coordination in movement.

This problem is beyond frustrating.

Until now nothing to solve the probl

At 1.72, there are good changes in the behavior of Darter. It can easily be stabilized when it can not come to the waypoint.
It's very good that he does not try to come to the waypoint when I remove the waypoint. It's almost a victory. Many thanks. I hope you will be able to teach Darter to fly, and not make unnecessary turns around the axis.

Lex added a comment.EditedAug 13 2017, 11:53 PM

In 1.74 \ DEV1.75. Now UAV in most trial flights does not fly to the waypoint. Almost always, deviates from the course to the waypoint and rotates, makes a roundabout, at a distance of 100-500 meters from the waypoint. These UAV rotations turn into an endless cycle, and do not stop without operator intervention.

Not sure if that blocking task has anything to do with this one.

Confirmed still an issue sometimes in RC 1.82.

Confirmed this behaviour still exists in latest release as well as current dev build (1.83.144597)

madpat3 added a subscriber: madpat3.EditedApr 9 2018, 12:27 PM

it seems, that at least for the darter , it doesn't delete last waypoint. set a waypoint for the darter via terminal. see how it begins to travel to it. then delete the waypoint. see, that it's still flying towards the already deleted waypoint.

@Lex: better?

Lex added a comment.EditedApr 24 2018, 7:19 AM

@madpat3 this ticket about UAV Darter which can't reach a traveling point.
For other problems with UAV Darter it is necessary to create other ticket with steps of reproduction of a problem.

Still not working in 2019

@Wulf My ticket T120265 was closed - as "no problem" or "this is according to the scenario." But you do not solve the problem of moving the darter to the control point. As a result, we have a non-working darter, we have the opportunity to stop the rotation in offline mode, but we lose control of the camera. What happens four years, and when this ticket will find the attention and solution?

Communication is not in the problem, but in the UAV, which comprehensively receives the problem of control / use in all functions that the player does not receive when using the UAV. By the sum of the problems, the player cannot comfortably use the UAV in the game for many problems. I point to this connection.

This seems to be a common problem for AI, which I pointed out on this ticket .

The greyhawks have a similar problem where they will randomly start going off in a random direction. Also this seems to happen after u try to couteract the bug with greyhawks automatically going into landing autopilot

c'mon guys :)
any news?

Not fixed in 2.0

Re-Tested in editor with an empty map with only BLUFOR units: UAV operator as player and UAVs. Tested UAV Darter, Pelican, Pelican Medical, and Falcon. All have the same behaviour. No mods loaded.

We need this re-assigned as the person it's assigned to hasn't had any activity since 2016.

Hopefully fixed with Arma 4!

Glad this is getting picked up again. Happy to help explain the troubleshooting steps. For a visual reference, here is a new video that I took today (30/10/2021)

Video has:

  • No mods loaded
  • Begins at game launch
  • Follows steps below
  • Has only 1 unit on the map (1x UAV Operator) so there are no "fleeing" or enemy detection issues
  • Purposely long to showcase the issue continues - Please fast forward as you need to see the next parts of the video, at no point has the video speed been changed (aka. no fast-forward or slowing down time)
  • Runs the scenario twice with the bug in both


  1. Launch Arma with no mods
  2. Open Editor
  3. Place down UAV operator unit
  4. Create UAV using scroll-wheel
  5. Open UAV terminal and connect to the UAV | Alternate: Scroll-wheel on the UAV to connect to UAV before opening terminal
  6. Shift-Click UAV to a point on the map
  7. Select Height (in the video I did 200)
  8. Watch UAV attempt to get to waypoint, eventually spinning out forever

Hope this helps and thanks for picking up issues like this again!
